How to Write a Research Paper Introduction (with Examples)

The research paper introduction section, along with the Title and Abstract, can be considered the face of any research paper. The following article is intended to guide you in organizing and writing the research paper introduction for a quality academic article or dissertation.

The research paper introduction aims to present the topic to the reader. A study will only be accepted for publishing if you can ascertain that the available literature cannot answer your research question. So it is important to ensure that you have read important studies on that particular topic, especially those within the last five to ten years, and that they are properly referenced in this section. 1 What should be included in the research paper introduction is decided by what you want to tell readers about the reason behind the research and how you plan to fill the knowledge gap. The best research paper introduction provides a systemic review of existing work and demonstrates additional work that needs to be done. It needs to be brief, captivating, and well-referenced; a well-drafted research paper introduction will help the researcher win half the battle.

The introduction for a research paper is where you set up your topic and approach for the reader. It has several key goals:

• Present your research topic
• Capture reader interest
• Summarize existing research
• Position your own approach
• Define your specific research problem and problem statement
• Highlight the novelty and contributions of the study
• Give an overview of the paper’s structure

The research paper introduction can vary in size and structure depending on whether your paper presents the results of original empirical research or is a review paper. Some research paper introduction examples are only half a page while others are a few pages long. In many cases, the introduction will be shorter than all of the other sections of your paper; its length depends on the size of your paper as a whole.

The introduction in a research paper is placed at the beginning to guide the reader from a broad subject area to the specific topic that your research addresses. They present the following information to the reader

• Scope: The topic covered in the research paper
• Context: Background of your topic
• Importance: Why your research matters in that particular area of research and the industry problem that can be targeted

The research paper introduction conveys a lot of information and can be considered an essential roadmap for the rest of your paper. A good introduction for a research paper is important for the following reasons:

• It stimulates your reader’s interest: A good introduction section can make your readers want to read your paper by capturing their interest. It informs the reader what they are going to learn and helps determine if the topic is of interest to them.
• It helps the reader understand the research background: Without a clear introduction, your readers may feel confused and even struggle when reading your paper. A good research paper introduction will prepare them for the in-depth research to come. It provides you the opportunity to engage with the readers and demonstrate your knowledge and authority on the specific topic.
• It explains why your research paper is worth reading: Your introduction can convey a lot of information to your readers. It introduces the topic, why the topic is important, and how you plan to proceed with your research.
• It helps guide the reader through the rest of the paper: The research paper introduction gives the reader a sense of the nature of the information that will support your arguments and the general organization of the paragraphs that will follow. It offers an overview of what to expect when reading the main body of your paper.

What are the parts of introduction in the research?

A good research paper introduction section should comprise three main elements: 2

• What is known: This sets the stage for your research. It informs the readers of what is known on the subject.
• What is lacking: This is aimed at justifying the reason for carrying out your research. This could involve investigating a new concept or method or building upon previous research.
• What you aim to do: This part briefly states the objectives of your research and its major contributions. Your detailed hypothesis will also form a part of this section.

How to write a research paper introduction?

The first step in writing the research paper introduction is to inform the reader what your topic is and why it’s interesting or important. This is generally accomplished with a strong opening statement. The second step involves establishing the kinds of research that have been done and ending with limitations or gaps in the research that you intend to address. Finally, the research paper introduction clarifies how your own research fits in and what problem it addresses. If your research involved testing hypotheses, these should be stated along with your research question. The hypothesis should be presented in the past tense since it will have been tested by the time you are writing the research paper introduction.

The following key points, with examples, can guide you when writing the research paper introduction section:

• Highlight the importance of the research field or topic
• Describe the background of the topic
• Present an overview of current research on the topic

Example: The inclusion of experiential and competency-based learning has benefitted electronics engineering education. Industry partnerships provide an excellent alternative for students wanting to engage in solving real-world challenges. Industry-academia participation has grown in recent years due to the need for skilled engineers with practical training and specialized expertise. However, from the educational perspective, many activities are needed to incorporate sustainable development goals into the university curricula and consolidate learning innovation in universities.

• Reveal a gap in existing research or oppose an existing assumption
• Formulate the research question

Example: There have been plausible efforts to integrate educational activities in higher education electronics engineering programs. However, very few studies have considered using educational research methods for performance evaluation of competency-based higher engineering education, with a focus on technical and or transversal skills. To remedy the current need for evaluating competencies in STEM fields and providing sustainable development goals in engineering education, in this study, a comparison was drawn between study groups without and with industry partners.

• State the purpose of your study
• Highlight the key characteristics of your study
• Describe important results
• Highlight the novelty of the study.
• Offer a brief overview of the structure of the paper.

Example: The study evaluates the main competency needed in the applied electronics course, which is a fundamental core subject for many electronics engineering undergraduate programs. We compared two groups, without and with an industrial partner, that offered real-world projects to solve during the semester. This comparison can help determine significant differences in both groups in terms of developing subject competency and achieving sustainable development goals.

The purpose of the research paper introduction is to introduce the reader to the problem definition, justify the need for the study, and describe the main theme of the study. The aim is to gain the reader’s attention by providing them with necessary background information and establishing the main purpose and direction of the research.

The length of the research paper introduction can vary across journals and disciplines. While there are no strict word limits for writing the research paper introduction, an ideal length would be one page, with a maximum of 400 words over 1-4 paragraphs. Generally, it is one of the shorter sections of the paper as the reader is assumed to have at least a reasonable knowledge about the topic. 2 For example, for a study evaluating the role of building design in ensuring fire safety, there is no need to discuss definitions and nature of fire in the introduction; you could start by commenting upon the existing practices for fire safety and how your study will add to the existing knowledge and practice.

When deciding what to include in the research paper introduction, the rest of the paper should also be considered. The aim is to introduce the reader smoothly to the topic and facilitate an easy read without much dependency on external sources. 3 Below is a list of elements you can include to prepare a research paper introduction outline and follow it when you are writing the research paper introduction. Topic introduction: This can include key definitions and a brief history of the topic. Research context and background: Offer the readers some general information and then narrow it down to specific aspects. Details of the research you conducted: A brief literature review can be included to support your arguments or line of thought. Rationale for the study: This establishes the relevance of your study and establishes its importance. Importance of your research: The main contributions are highlighted to help establish the novelty of your study Research hypothesis: Introduce your research question and propose an expected outcome. Organization of the paper: Include a short paragraph of 3-4 sentences that highlights your plan for the entire paper

Cite only works that are most relevant to your topic; as a general rule, you can include one to three. Note that readers want to see evidence of original thinking. So it is better to avoid using too many references as it does not leave much room for your personal standpoint to shine through. Citations in your research paper introduction support the key points, and the number of citations depend on the subject matter and the point discussed. If the research paper introduction is too long or overflowing with citations, it is better to cite a few review articles rather than the individual articles summarized in the review. A good point to remember when citing research papers in the introduction section is to include at least one-third of the references in the introduction.

The literature review plays a significant role in the research paper introduction section. A good literature review accomplishes the following: Introduces the topic – Establishes the study’s significance – Provides an overview of the relevant literature – Provides context for the study using literature – Identifies knowledge gaps However, remember to avoid making the following mistakes when writing a research paper introduction: Do not use studies from the literature review to aggressively support your research Avoid direct quoting Do not allow literature review to be the focus of this section. Instead, the literature review should only aid in setting a foundation for the manuscript.

Remember the following key points for writing a good research paper introduction: 4

• Avoid stuffing too much general information: Avoid including what an average reader would know and include only that information related to the problem being addressed in the research paper introduction. For example, when describing a comparative study of non-traditional methods for mechanical design optimization, information related to the traditional methods and differences between traditional and non-traditional methods would not be relevant. In this case, the introduction for the research paper should begin with the state-of-the-art non-traditional methods and methods to evaluate the efficiency of newly developed algorithms.
• Avoid packing too many references: Cite only the required works in your research paper introduction. The other works can be included in the discussion section to strengthen your findings.
• Avoid extensive criticism of previous studies: Avoid being overly critical of earlier studies while setting the rationale for your study. A better place for this would be the Discussion section, where you can highlight the advantages of your method.
• Avoid describing conclusions of the study: When writing a research paper introduction remember not to include the findings of your study. The aim is to let the readers know what question is being answered. The actual answer should only be given in the Results and Discussion section.

To summarize, the research paper introduction section should be brief yet informative. It should convince the reader the need to conduct the study and motivate him to read further.

How to Write an Introduction for a Research Paper

Table of Contents

Writing an introduction for a research paper is a critical element of your paper, but it can seem challenging to encapsulate enormous amount of information into a concise form. The introduction of your research paper sets the tone for your research and provides the context for your study. In this article, we will guide you through the process of writing an effective introduction that grabs the reader's attention and captures the essence of your research paper.

Understanding the Purpose of a Research Paper Introduction

The introduction acts as a road map for your research paper, guiding the reader through the main ideas and arguments. The purpose of the introduction is to present your research topic to the readers and provide a rationale for why your study is relevant. It helps the reader locate your research and its relevance in the broader field of related scientific explorations. Additionally, the introduction should inform the reader about the objectives and scope of your study, giving them an overview of what to expect in the paper. By including a comprehensive introduction, you establish your credibility as an author and convince the reader that your research is worth their time and attention.

Key Elements to Include in Your Introduction

When writing your research paper introduction, there are several key elements you should include to ensure it is comprehensive and informative.

• A hook or attention-grabbing statement to capture the reader's interest.  It can be a thought-provoking question, a surprising statistic, or a compelling anecdote that relates to your research topic.
• A brief overview of the research topic and its significance. By highlighting the gap in existing knowledge or the problem your research aims to address, you create a compelling case for the relevance of your study.
• A clear research question or problem statement. This serves as the foundation of your research and guides the reader in understanding the unique focus of your study. It should be concise, specific, and clearly articulated.
• An outline of the paper's structure and main arguments, to help the readers navigate through the paper with ease.

Preparing to Write Your Introduction

Before diving into writing your introduction, it is essential to prepare adequately. This involves 3 important steps:

• Conducting Preliminary Research: Immerse yourself in the existing literature to develop a clear research question and position your study within the academic discourse.
• Identifying Your Thesis Statement: Define a specific, focused, and debatable thesis statement, serving as a roadmap for your paper.
• Considering Broader Context: Reflect on the significance of your research within your field, understanding its potential impact and contribution.

By engaging in these preparatory steps, you can ensure that your introduction is well-informed, focused, and sets the stage for a compelling research paper.

Structuring Your Introduction

Now that you have prepared yourself to tackle the introduction, it's time to structure it effectively. A well-structured introduction will engage the reader from the beginning and provide a logical flow to your research paper.

Starting with a Hook

Begin your introduction with an attention-grabbing hook that captivates the reader's interest. This hook serves as a way to make your introduction more engaging and compelling. For example, if you are writing a research paper on the impact of climate change on biodiversity, you could start your introduction with a statistic about the number of species that have gone extinct due to climate change. This will immediately grab the reader's attention and make them realize the urgency and importance of the topic.

Introducing Your Topic

Provide a brief overview, which should give the reader a general understanding of the subject matter and its significance. Explain the importance of the topic and its relevance to the field. This will help the reader understand why your research is significant and why they should continue reading. Continuing with the example of climate change and biodiversity, you could explain how climate change is one of the greatest threats to global biodiversity, how it affects ecosystems, and the potential consequences for both wildlife and human populations. By providing this context, you are setting the stage for the rest of your research paper and helping the reader understand the importance of your study.

Presenting Your Thesis Statement

The thesis statement should directly address your research question and provide a preview of the main arguments or findings discussed in your paper. Make sure your thesis statement is clear, concise, and well-supported by the evidence you will present in your research paper. By presenting a strong and focused thesis statement, you are providing the reader with the information they could anticipate in your research paper. This will help them understand the purpose and scope of your study and will make them more inclined to continue reading.

Writing Techniques for an Effective Introduction

When crafting an introduction, it is crucial to pay attention to the finer details that can elevate your writing to the next level. By utilizing specific writing techniques, you can captivate your readers and draw them into your research journey.

Using Clear and Concise Language

One of the most important writing techniques to employ in your introduction is the use of clear and concise language. By choosing your words carefully, you can effectively convey your ideas to the reader. It is essential to avoid using jargon or complex terminology that may confuse or alienate your audience. Instead, focus on communicating your research in a straightforward manner to ensure that your introduction is accessible to both experts in your field and those who may be new to the topic. This approach allows you to engage a broader audience and make your research more inclusive.

Establishing the Relevance of Your Research

One way to establish the relevance of your research is by highlighting how it fills a gap in the existing literature. Explain how your study addresses a significant research question that has not been adequately explored. By doing this, you demonstrate that your research is not only unique but also contributes to the broader knowledge in your field. Furthermore, it is important to emphasize the potential impact of your research. Whether it is advancing scientific understanding, informing policy decisions, or improving practical applications, make it clear to the reader how your study can make a difference.

By employing these two writing techniques in your introduction, you can effectively engage your readers. Take your time to craft an introduction that is both informative and captivating, leaving your readers eager to delve deeper into your research.

Revising and Polishing Your Introduction

Once you have written your introduction, it is crucial to revise and polish it to ensure that it effectively sets the stage for your research paper.

Self-Editing Techniques

Review your introduction for clarity, coherence, and logical flow. Ensure each paragraph introduces a new idea or argument with smooth transitions.

Check for grammatical errors, spelling mistakes, and awkward sentence structures.

Ensure that your introduction aligns with the overall tone and style of your research paper.

Seeking Feedback for Improvement

Consider seeking feedback from peers, colleagues, or your instructor. They can provide valuable insights and suggestions for improving your introduction. Be open to constructive criticism and use it to refine your introduction and make it more compelling for the reader.

Writing an introduction for a research paper requires careful thought and planning. By understanding the purpose of the introduction, preparing adequately, structuring effectively, and employing writing techniques, you can create an engaging and informative introduction for your research. Remember to revise and polish your introduction to ensure that it accurately represents the main ideas and arguments in your research paper. With a well-crafted introduction, you will capture the reader's attention and keep them inclined to your paper.

The introduction leads the reader from a general subject area to a particular topic of inquiry. It establishes the scope, context, and significance of the research being conducted by summarizing current understanding and background information about the topic, stating the purpose of the work in the form of the research problem supported by a hypothesis or a set of questions, explaining briefly the methodological approach used to examine the research problem, highlighting the potential outcomes your study can reveal, and outlining the remaining structure and organization of the paper.

Importance of a Good Introduction

Think of the introduction as a mental road map that must answer for the reader these four questions:

• What was I studying?
• Why was this topic important to investigate?
• What did we know about this topic before I did this study?
• How will this study advance new knowledge or new ways of understanding?

According to Reyes, there are three overarching goals of a good introduction: 1) ensure that you summarize prior studies about the topic in a manner that lays a foundation for understanding the research problem; 2) explain how your study specifically addresses gaps in the literature, insufficient consideration of the topic, or other deficiency in the literature; and, 3) note the broader theoretical, empirical, and/or policy contributions and implications of your research.

A well-written introduction is important because, quite simply, you never get a second chance to make a good first impression. The opening paragraphs of your paper will provide your readers with their initial impressions about the logic of your argument, your writing style, the overall quality of your research, and, ultimately, the validity of your findings and conclusions. A vague, disorganized, or error-filled introduction will create a negative impression, whereas, a concise, engaging, and well-written introduction will lead your readers to think highly of your analytical skills, your writing style, and your research approach. All introductions should conclude with a brief paragraph that describes the organization of the rest of the paper.

Structure and Writing Style

I.  Structure and Approach

The introduction is the broad beginning of the paper that answers three important questions for the reader:

• What is this?
• Why should I read it?
• What do you want me to think about / consider doing / react to?

Think of the structure of the introduction as an inverted triangle of information that lays a foundation for understanding the research problem. Organize the information so as to present the more general aspects of the topic early in the introduction, then narrow your analysis to more specific topical information that provides context, finally arriving at your research problem and the rationale for studying it [often written as a series of key questions to be addressed or framed as a hypothesis or set of assumptions to be tested] and, whenever possible, a description of the potential outcomes your study can reveal.

These are general phases associated with writing an introduction: 1.  Establish an area to research by:

• Highlighting the importance of the topic, and/or
• Making general statements about the topic, and/or
• Presenting an overview on current research on the subject.

2.  Identify a research niche by:

• Opposing an existing assumption, and/or
• Revealing a gap in existing research, and/or
• Formulating a research question or problem, and/or
• Continuing a disciplinary tradition.

3.  Place your research within the research niche by:

• Stating the intent of your study,
• Outlining the key characteristics of your study,
• Describing important results, and
• Giving a brief overview of the structure of the paper.

NOTE:   It is often useful to review the introduction late in the writing process. This is appropriate because outcomes are unknown until you've completed the study. After you complete writing the body of the paper, go back and review introductory descriptions of the structure of the paper, the method of data gathering, the reporting and analysis of results, and the conclusion. Reviewing and, if necessary, rewriting the introduction ensures that it correctly matches the overall structure of your final paper.

II.  Delimitations of the Study

Delimitations refer to those characteristics that limit the scope and define the conceptual boundaries of your research . This is determined by the conscious exclusionary and inclusionary decisions you make about how to investigate the research problem. In other words, not only should you tell the reader what it is you are studying and why, but you must also acknowledge why you rejected alternative approaches that could have been used to examine the topic.

Obviously, the first limiting step was the choice of research problem itself. However, implicit are other, related problems that could have been chosen but were rejected. These should be noted in the conclusion of your introduction. For example, a delimitating statement could read, "Although many factors can be understood to impact the likelihood young people will vote, this study will focus on socioeconomic factors related to the need to work full-time while in school." The point is not to document every possible delimiting factor, but to highlight why previously researched issues related to the topic were not addressed.

Examples of delimitating choices would be:

• The key aims and objectives of your study,
• The research questions that you address,
• The variables of interest [i.e., the various factors and features of the phenomenon being studied],
• The method(s) of investigation,
• The time period your study covers, and
• Any relevant alternative theoretical frameworks that could have been adopted.

Review each of these decisions. Not only do you clearly establish what you intend to accomplish in your research, but you should also include a declaration of what the study does not intend to cover. In the latter case, your exclusionary decisions should be based upon criteria understood as, "not interesting"; "not directly relevant"; “too problematic because..."; "not feasible," and the like. Make this reasoning explicit!

NOTE:   Delimitations refer to the initial choices made about the broader, overall design of your study and should not be confused with documenting the limitations of your study discovered after the research has been completed.

ANOTHER NOTE : Do not view delimitating statements as admitting to an inherent failing or shortcoming in your research. They are an accepted element of academic writing intended to keep the reader focused on the research problem by explicitly defining the conceptual boundaries and scope of your study. It addresses any critical questions in the reader's mind of, "Why the hell didn't the author examine this?"

III.  The Narrative Flow

Issues to keep in mind that will help the narrative flow in your introduction :

• Your introduction should clearly identify the subject area of interest . A simple strategy to follow is to use key words from your title in the first few sentences of the introduction. This will help focus the introduction on the topic at the appropriate level and ensures that you get to the subject matter quickly without losing focus, or discussing information that is too general.
• Establish context by providing a brief and balanced review of the pertinent published literature that is available on the subject. The key is to summarize for the reader what is known about the specific research problem before you did your analysis. This part of your introduction should not represent a comprehensive literature review--that comes next. It consists of a general review of the important, foundational research literature [with citations] that establishes a foundation for understanding key elements of the research problem. See the drop-down menu under this tab for " Background Information " regarding types of contexts.
• Clearly state the hypothesis that you investigated . When you are first learning to write in this format it is okay, and actually preferable, to use a past statement like, "The purpose of this study was to...." or "We investigated three possible mechanisms to explain the...."
• Why did you choose this kind of research study or design? Provide a clear statement of the rationale for your approach to the problem studied. This will usually follow your statement of purpose in the last paragraph of the introduction.

IV.  Engaging the Reader

A research problem in the social sciences can come across as dry and uninteresting to anyone unfamiliar with the topic . Therefore, one of the goals of your introduction is to make readers want to read your paper. Here are several strategies you can use to grab the reader's attention:

• Open with a compelling story . Almost all research problems in the social sciences, no matter how obscure or esoteric , are really about the lives of people. Telling a story that humanizes an issue can help illuminate the significance of the problem and help the reader empathize with those affected by the condition being studied.
• Include a strong quotation or a vivid, perhaps unexpected, anecdote . During your review of the literature, make note of any quotes or anecdotes that grab your attention because they can used in your introduction to highlight the research problem in a captivating way.
• Pose a provocative or thought-provoking question . Your research problem should be framed by a set of questions to be addressed or hypotheses to be tested. However, a provocative question can be presented in the beginning of your introduction that challenges an existing assumption or compels the reader to consider an alternative viewpoint that helps establish the significance of your study. 
• Describe a puzzling scenario or incongruity . This involves highlighting an interesting quandary concerning the research problem or describing contradictory findings from prior studies about a topic. Posing what is essentially an unresolved intellectual riddle about the problem can engage the reader's interest in the study.
• Cite a stirring example or case study that illustrates why the research problem is important . Draw upon the findings of others to demonstrate the significance of the problem and to describe how your study builds upon or offers alternatives ways of investigating this prior research.

NOTE:   It is important that you choose only one of the suggested strategies for engaging your readers. This avoids giving an impression that your paper is more flash than substance and does not distract from the substance of your study.

Giving the dictionary definition of words related to the research problem may appear appropriate because it is important to define specific terminology that readers may be unfamiliar with. However, anyone can look a word up in the dictionary and a general dictionary is not a particularly authoritative source because it doesn't take into account the context of your topic and doesn't offer particularly detailed information. Also, placed in the context of a particular discipline, a term or concept may have a different meaning than what is found in a general dictionary. If you feel that you must seek out an authoritative definition, use a subject specific dictionary or encyclopedia [e.g., if you are a sociology student, search for dictionaries of sociology]. A good database for obtaining definitive definitions of concepts or terms is Credo Reference .

Another Writing Tip

When Do I Begin?

A common question asked at the start of any paper is, "Where should I begin?" An equally important question to ask yourself is, "When do I begin?" Research problems in the social sciences rarely rest in isolation from history. Therefore, it is important to lay a foundation for understanding the historical context underpinning the research problem. However, this information should be brief and succinct and begin at a point in time that illustrates the study's overall importance. For example, a study that investigates coffee cultivation and export in West Africa as a key stimulus for local economic growth needs to describe the beginning of exporting coffee in the region and establishing why economic growth is important. You do not need to give a long historical explanation about coffee exports in Africa. If a research problem requires a substantial exploration of the historical context, do this in the literature review section. In your introduction, make note of this as part of the "roadmap" [see below] that you use to describe the organization of your paper.

Yet Another Writing Tip

Always End with a Roadmap

The final paragraph or sentences of your introduction should forecast your main arguments and conclusions and provide a brief description of the rest of the paper [the "roadmap"] that let's the reader know where you are going and what to expect. A roadmap is important because it helps the reader place the research problem within the context of their own perspectives about the topic. In addition, concluding your introduction with an explicit roadmap tells the reader that you have a clear understanding of the structural purpose of your paper. In this way, the roadmap acts as a type of promise to yourself and to your readers that you will follow a consistent and coherent approach to addressing the topic of inquiry. Refer to it often to help keep your writing focused and organized.

How to write an effective introduction for your research paper

Last updated

However, the introduction is a vital element of your research paper. It helps the reader decide whether your paper is worth their time. As such, it's worth taking your time to get it right.

In this article, we'll tell you everything you need to know about writing an effective introduction for your research paper.

• The importance of an introduction in research papers

The primary purpose of an introduction is to provide an overview of your paper. This lets readers gauge whether they want to continue reading or not. The introduction should provide a meaningful roadmap of your research to help them make this decision. It should let readers know whether the information they're interested in is likely to be found in the pages that follow.

Aside from providing readers with information about the content of your paper, the introduction also sets the tone. It shows readers the style of language they can expect, which can further help them to decide how far to read.

When you take into account both of these roles that an introduction plays, it becomes clear that crafting an engaging introduction is the best way to get your paper read more widely. First impressions count, and the introduction provides that impression to readers.

• The optimum length for a research paper introduction

While there's no magic formula to determine exactly how long a research paper introduction should be, there are a few guidelines. Some variables that impact the ideal introduction length include:

Field of study

Complexity of the topic

Specific requirements of the course or publication

A commonly recommended length of a research paper introduction is around 10% of the total paper’s length. So, a ten-page paper has a one-page introduction. If the topic is complex, it may require more background to craft a compelling intro. Humanities papers tend to have longer introductions than those of the hard sciences.

The best way to craft an introduction of the right length is to focus on clarity and conciseness. Tell the reader only what is necessary to set up your research. An introduction edited down with this goal in mind should end up at an acceptable length.

• Evaluating successful research paper introductions

A good way to gauge how to create a great introduction is by looking at examples from across your field. The most influential and well-regarded papers should provide some insights into what makes a good introduction.

Dissecting examples: what works and why

We can make some general assumptions by looking at common elements of a good introduction, regardless of the field of research.

A common structure is to start with a broad context, and then narrow that down to specific research questions or hypotheses. This creates a funnel that establishes the scope and relevance.

The most effective introductions are careful about the assumptions they make regarding reader knowledge. By clearly defining key terms and concepts instead of assuming the reader is familiar with them, these introductions set a more solid foundation for understanding.

To pull in the reader and make that all-important good first impression, excellent research paper introductions will often incorporate a compelling narrative or some striking fact that grabs the reader's attention.

Finally, good introductions provide clear citations from past research to back up the claims they're making. In the case of argumentative papers or essays (those that take a stance on a topic or issue), a strong thesis statement compels the reader to continue reading.

Common pitfalls to avoid in research paper introductions

You can also learn what not to do by looking at other research papers. Many authors have made mistakes you can learn from.

We've talked about the need to be clear and concise. Many introductions fail at this; they're verbose, vague, or otherwise fail to convey the research problem or hypothesis efficiently. This often comes in the form of an overemphasis on background information, which obscures the main research focus.

Ensure your introduction provides the proper emphasis and excitement around your research and its significance. Otherwise, fewer people will want to read more about it.

• Crafting a compelling introduction for a research paper

Let’s take a look at the steps required to craft an introduction that pulls readers in and compels them to learn more about your research.

Step 1: Capturing interest and setting the scene

To capture the reader's interest immediately, begin your introduction with a compelling question, a surprising fact, a provocative quote, or some other mechanism that will hook readers and pull them further into the paper.

As they continue reading, the introduction should contextualize your research within the current field, showing readers its relevance and importance. Clarify any essential terms that will help them better understand what you're saying. This keeps the fundamentals of your research accessible to all readers from all backgrounds.

Step 2: Building a solid foundation with background information

Including background information in your introduction serves two major purposes:

It helps to clarify the topic for the reader

It establishes the depth of your research

The approach you take when conveying this information depends on the type of paper.

For argumentative papers, you'll want to develop engaging background narratives. These should provide context for the argument you'll be presenting.

For empirical papers, highlighting past research is the key. Often, there will be some questions that weren't answered in those past papers. If your paper is focused on those areas, those papers make ideal candidates for you to discuss and critique in your introduction.

Step 3: Pinpointing the research challenge

To capture the attention of the reader, you need to explain what research challenges you'll be discussing.

For argumentative papers, this involves articulating why the argument you'll be making is important. What is its relevance to current discussions or problems? What is the potential impact of people accepting or rejecting your argument?

For empirical papers, explain how your research is addressing a gap in existing knowledge. What new insights or contributions will your research bring to your field?

Step 4: Clarifying your research aims and objectives

We mentioned earlier that the introduction to a research paper can serve as a roadmap for what's within. We've also frequently discussed the need for clarity. This step addresses both of these.

When writing an argumentative paper, craft a thesis statement with impact. Clearly articulate what your position is and the main points you intend to present. This will map out for the reader exactly what they'll get from reading the rest.

For empirical papers, focus on formulating precise research questions and hypotheses. Directly link them to the gaps or issues you've identified in existing research to show the reader the precise direction your research paper will take.

Step 5: Sketching the blueprint of your study

Continue building a roadmap for your readers by designing a structured outline for the paper. Guide the reader through your research journey, explaining what the different sections will contain and their relationship to one another.

This outline should flow seamlessly as you move from section to section. Creating this outline early can also help guide the creation of the paper itself, resulting in a final product that's better organized. In doing so, you'll craft a paper where each section flows intuitively from the next.

Step 6: Integrating your research question

To avoid letting your research question get lost in background information or clarifications, craft your introduction in such a way that the research question resonates throughout. The research question should clearly address a gap in existing knowledge or offer a new perspective on an existing problem.

Tell users your research question explicitly but also remember to frequently come back to it. When providing context or clarification, point out how it relates to the research question. This keeps your focus where it needs to be and prevents the topic of the paper from becoming under-emphasized.

Step 7: Establishing the scope and limitations

So far, we've talked mostly about what's in the paper and how to convey that information to readers. The opposite is also important. Information that's outside the scope of your paper should be made clear to the reader in the introduction so their expectations for what is to follow are set appropriately.

Similarly, be honest and upfront about the limitations of the study. Any constraints in methodology, data, or how far your findings can be generalized should be fully communicated in the introduction.

Step 8: Concluding the introduction with a promise

The final few lines of the introduction are your last chance to convince people to continue reading the rest of the paper. Here is where you should make it very clear what benefit they'll get from doing so. What topics will be covered? What questions will be answered? Make it clear what they will get for continuing.

By providing a quick recap of the key points contained in the introduction in its final lines and properly setting the stage for what follows in the rest of the paper, you refocus the reader's attention on the topic of your research and guide them to read more.

• Research paper introduction best practices

Following the steps above will give you a compelling introduction that hits on all the key points an introduction should have. Some more tips and tricks can make an introduction even more polished.

As you follow the steps above, keep the following tips in mind.

Set the right tone and style

Like every piece of writing, a research paper should be written for the audience. That is to say, it should match the tone and style that your academic discipline and target audience expect. This is typically a formal and academic tone, though the degree of formality varies by field.

Kno w the audience

The perfect introduction balances clarity with conciseness. The amount of clarification required for a given topic depends greatly on the target audience. Knowing who will be reading your paper will guide you in determining how much background information is required.

Adopt the CARS (create a research space) model

The CARS model is a helpful tool for structuring introductions. This structure has three parts. The beginning of the introduction establishes the general research area. Next, relevant literature is reviewed and critiqued. The final section outlines the purpose of your study as it relates to the previous parts.

Master the art of funneling

The CARS method is one example of a well-funneled introduction. These start broadly and then slowly narrow down to your specific research problem. It provides a nice narrative flow that provides the right information at the right time. If you stray from the CARS model, try to retain this same type of funneling.

Incorporate narrative element

People read research papers largely to be informed. But to inform the reader, you have to hold their attention. A narrative style, particularly in the introduction, is a great way to do that. This can be a compelling story, an intriguing question, or a description of a real-world problem.

Write the introduction last

By writing the introduction after the rest of the paper, you'll have a better idea of what your research entails and how the paper is structured. This prevents the common problem of writing something in the introduction and then forgetting to include it in the paper. It also means anything particularly exciting in the paper isn’t neglected in the intro.

How to Write an Introduction for a Research Paper

How to write an introduction for a research paper? Eventually (and with practice) all writers will develop their own strategy for writing the perfect introduction for a research paper. Once you are comfortable with writing, you will probably find your own, but coming up with a good strategy can be tough for beginning writers.

The Purpose of an Introduction

Your opening paragraphs, phrases for introducing thesis statements, research paper introduction examples, using the introduction to map out your research paper.

• First write your thesis.Your thesis should state the main idea in specific terms.
• After you have a working thesis, tackle the body of your paper before you write the rest of the introduction. Each paragraph in the body should explore one specific topic that proves, or summarizes your thesis. Writing is a thinking process. Once you have worked your way through that process by writing the body of the paper, you will have an intimate understanding of how you are supporting your thesis. After you have written the body paragraphs, go back and rewrite your thesis to make it more specific and to connect it to the topics you addressed in the body paragraph.
• Revise your introduction several times, saving each revision. Be sure your introduction previews the topics you are presenting in your paper. One way of doing this is to use keywords from the topic sentences in each paragraph to introduce, or preview, the topics in your introduction.This “preview” will give your reader a context for understanding how you will make your case.
• Experiment by taking different approaches to your thesis with every revision you make. Play with the language in the introduction. Strike a new tone. Go back and compare versions. Then pick the one that works most effectively with the body of your research paper.
• Do not try to pack everything you want to say into your introduction. Just as your introduction should not be too short, it should also not be too long. Your introduction should be about the same length as any other paragraph in your research paper. Let the content—what you have to say—dictate the length.

The first page of your research paper should draw the reader into the text. It is the paper’s most important page and, alas, often the worst written. There are two culprits here and effective ways to cope with both of them.

First, the writer is usually straining too hard to say something terribly BIG and IMPORTANT about the thesis topic. The goal is worthy, but the aim is unrealistically high. The result is often a muddle of vague platitudes rather than a crisp, compelling introduction to the thesis. Want a familiar example? Listen to most graduation speakers. Their goal couldn’t be loftier: to say what education means and to tell an entire football stadium how to live the rest of their lives. The results are usually an avalanche of clichés and sodden prose.

The second culprit is bad timing. The opening and concluding paragraphs are usually written late in the game, after the rest of the thesis is finished and polished. There’s nothing wrong with writing these sections last. It’s usually the right approach since you need to know exactly what you are saying in the substantive middle sections of the thesis before you can introduce them effectively or draw together your findings. But having waited to write the opening and closing sections, you need to review and edit them several times to catch up. Otherwise, you’ll putting the most jagged prose in the most tender spots. Edit and polish your opening paragraphs with extra care. They should draw readers into the paper.

After you’ve done some extra polishing, I suggest a simple test for the introductory section. As an experiment, chop off the first few paragraphs. Let the paper begin on, say, paragraph 2 or even page 2. If you don’t lose much, or actually gain in clarity and pace, then you’ve got a problem.

There are two solutions. One is to start at this new spot, further into the text. After all, that’s where you finally gain traction on your subject. That works best in some cases, and we occasionally suggest it. The alternative, of course, is to write a new opening that doesn’t flop around, saying nothing.

What makes a good opening? Actually, they come in several flavors. One is an intriguing story about your topic. Another is a brief, compelling quote. When you run across them during your reading, set them aside for later use. Don’t be deterred from using them because they “don’t seem academic enough.” They’re fine as long as the rest of the paper doesn’t sound like you did your research in People magazine. The third, and most common, way to begin is by stating your main questions, followed by a brief comment about why they matter.

Whichever opening you choose, it should engage your readers and coax them to continue. Having done that, you should give them a general overview of the project—the main issues you will cover, the material you will use, and your thesis statement (that is, your basic approach to the topic). Finally, at the end of the introductory section, give your readers a brief road map, showing how the paper will unfold. How you do that depends on your topic but here are some general suggestions for phrase choice that may help:

• This analysis will provide …
• This paper analyzes the relationship between …
• This paper presents an analysis of …
• This paper will argue that …
• This topic supports the argument that…
• Research supports the opinion that …
• This paper supports the opinion that …

Quotes, anecdotes, questions, examples, and broad statements—all of them can used successfully to write an introduction for a research paper. It’s instructive to see them in action, in the hands of skilled academic writers.

Let’s begin with David M. Kennedy’s superb history, Freedom from Fear: The American People in Depression and War, 1929–1945 . Kennedy begins each chapter with a quote, followed by his text. The quote above chapter 1 shows President Hoover speaking in 1928 about America’s golden future. The text below it begins with the stock market collapse of 1929. It is a riveting account of just how wrong Hoover was. The text about the Depression is stronger because it contrasts so starkly with the optimistic quotation.

“We in America today are nearer the final triumph over poverty than ever before in the history of any land.”—Herbert Hoover, August 11, 1928 Like an earthquake, the stock market crash of October 1929 cracked startlingly across the United States, the herald of a crisis that was to shake the American way of life to its foundations. The events of the ensuing decade opened a fissure across the landscape of American history no less gaping than that opened by the volley on Lexington Common in April 1775 or by the bombardment of Sumter on another April four score and six years later. The ratcheting ticker machines in the autumn of 1929 did not merely record avalanching stock prices. In time they came also to symbolize the end of an era. (David M. Kennedy, Freedom from Fear: The American People in Depression and War, 1929–1945 . New York: Oxford University Press, 1999, p. 10)

Kennedy has exciting, wrenching material to work with. John Mueller faces the exact opposite problem. In Retreat from Doomsday: The Obsolescence of Major War , he is trying to explain why Great Powers have suddenly stopped fighting each other. For centuries they made war on each other with devastating regularity, killing millions in the process. But now, Mueller thinks, they have not just paused; they have stopped permanently. He is literally trying to explain why “nothing is happening now.” That may be an exciting topic intellectually, it may have great practical significance, but “nothing happened” is not a very promising subject for an exciting opening paragraph. Mueller manages to make it exciting and, at the same time, shows why it matters so much. Here’s his opening, aptly entitled “History’s Greatest Nonevent”:

On May 15, 1984, the major countries of the developed world had managed to remain at peace with each other for the longest continuous stretch of time since the days of the Roman Empire. If a significant battle in a war had been fought on that day, the press would have bristled with it. As usual, however, a landmark crossing in the history of peace caused no stir: the most prominent story in the New York Times that day concerned the saga of a manicurist, a machinist, and a cleaning woman who had just won a big Lotto contest. This book seeks to develop an explanation for what is probably the greatest nonevent in human history. (John Mueller, Retreat from Doomsday: The Obsolescence of Major War . New York: Basic Books, 1989, p. 3)

In the space of a few sentences, Mueller sets up his puzzle and reveals its profound human significance. At the same time, he shows just how easy it is to miss this milestone in the buzz of daily events. Notice how concretely he does that. He doesn’t just say that the New York Times ignored this record setting peace. He offers telling details about what they covered instead: “a manicurist, a machinist, and a cleaning woman who had just won a big Lotto contest.” Likewise, David Kennedy immediately entangles us in concrete events: the stunning stock market crash of 1929. These are powerful openings that capture readers’ interests, establish puzzles, and launch narratives.

Sociologist James Coleman begins in a completely different way, by posing the basic questions he will study. His ambitious book, Foundations of Social Theory , develops a comprehensive theory of social life, so it is entirely appropriate for him to begin with some major questions. But he could just as easily have begun with a compelling story or anecdote. He includes many of them elsewhere in his book. His choice for the opening, though, is to state his major themes plainly and frame them as a paradox. Sociologists, he says, are interested in aggregate behavior—how people act in groups, organizations, or large numbers—yet they mostly examine individuals:

A central problem in social science is that of accounting for the function of some kind of social system. Yet in most social research, observations are not made on the system as a whole, but on some part of it. In fact, the natural unit of observation is the individual person…  This has led to a widening gap between theory and research… (James S. Coleman, Foundations of Social Theory . Cambridge, MA: Harvard University Press, 1990, pp. 1–2)

After expanding on this point, Coleman explains that he will not try to remedy the problem by looking solely at groups or aggregate-level data. That’s a false solution, he says, because aggregates don’t act; individuals do. So the real problem is to show the links between individual actions and aggregate outcomes, between the micro and the macro.

The major problem for explanations of system behavior based on actions and orientations at a level below that of the system [in this case, on individual-level actions] is that of moving from the lower level to the system level. This has been called the micro-to-macro problem, and it is pervasive throughout the social sciences. (Coleman, Foundations of Social Theory , p. 6)

Explaining how to deal with this “micro-to-macro problem” is the central issue of Coleman’s book, and he announces it at the beginning.

Coleman’s theory-driven opening stands at the opposite end of the spectrum from engaging stories or anecdotes, which are designed to lure the reader into the narrative and ease the path to a more analytic treatment later in the text. Take, for example, the opening sentences of Robert L. Herbert’s sweeping study Impressionism: Art, Leisure, and Parisian Society : “When Henry Tuckerman came to Paris in 1867, one of the thousands of Americans attracted there by the huge international exposition, he was bowled over by the extraordinary changes since his previous visit twenty years before.” (Robert L. Herbert, Impressionism: Art, Leisure, and Parisian Society . New Haven, CT: Yale University Press, 1988, p. 1.) Herbert fills in the evocative details to set the stage for his analysis of the emerging Impressionist art movement and its connection to Parisian society and leisure in this period.

David Bromwich writes about Wordsworth, a poet so familiar to students of English literature that it is hard to see him afresh, before his great achievements, when he was just a young outsider starting to write. To draw us into Wordsworth’s early work, Bromwich wants us to set aside our entrenched images of the famous mature poet and see him as he was in the 1790s, as a beginning writer on the margins of society. He accomplishes this ambitious task in the opening sentences of Disowned by Memory: Wordsworth’s Poetry of the 1790s :

Wordsworth turned to poetry after the revolution to remind himself that he was still a human being. It was a curious solution, to a difficulty many would not have felt. The whole interest of his predicament is that he did feel it. Yet Wordsworth is now so established an eminence—his name so firmly fixed with readers as a moralist of self-trust emanating from complete self-security—that it may seem perverse to imagine him as a criminal seeking expiation. Still, that is a picture we get from The Borderers and, at a longer distance, from “Tintern Abbey.” (David Bromwich, Disowned by Memory: Wordsworth’s Poetry of the 1790s . Chicago: University of Chicago Press, 1998, p. 1)

That’s a wonderful opening! Look at how much Bromwich accomplishes in just a few words. He not only prepares the way for analyzing Wordsworth’s early poetry; he juxtaposes the anguished young man who wrote it to the self-confident, distinguished figure he became—the eminent man we can’t help remembering as we read his early poetry.

Let us highlight a couple of other points in this passage because they illustrate some intelligent writing choices. First, look at the odd comma in this sentence: “It was a curious solution, to a difficulty many would not have felt.” Any standard grammar book would say that comma is wrong and should be omitted. Why did Bromwich insert it? Because he’s a fine writer, thinking of his sentence rhythm and the point he wants to make. The comma does exactly what it should. It makes us pause, breaking the sentence into two parts, each with an interesting point. One is that Wordsworth felt a difficulty others would not have; the other is that he solved it in a distinctive way. It would be easy for readers to glide over this double message, so Bromwich has inserted a speed bump to slow us down. Most of the time, you should follow grammatical rules, like those about commas, but you should bend them when it serves a good purpose. That’s what the writer does here.

The second small point is the phrase “after the revolution” in the first sentence: “Wordsworth turned to poetry after the revolution to remind himself that he was still a human being.” Why doesn’t Bromwich say “after the French Revolution”? Because he has judged his book’s audience. He is writing for specialists who already know which revolution is reverberating through English life in the 1790s. It is the French Revolution, not the earlier loss of the American colonies. If Bromwich were writing for a much broader audience—say, the New York Times Book Review—he would probably insert the extra word to avoid confusion.

The message “Know your audience” applies to all writers. Don’t talk down to them by assuming they can’t get dressed in the morning. Don’t strut around showing off your book learnin’ by tossing in arcane facts and esoteric language for its own sake. Neither will win over readers.

Bromwich, Herbert, and Coleman open their works in different ways, but their choices work well for their different texts. Your task is to decide what kind of opening will work best for yours. Don’t let that happen by default, by grabbing the first idea you happen upon. Consider a couple of different ways of opening your thesis and then choose the one you prefer. Give yourself some options, think them over, then make an informed choice.

Whether you begin with a story, puzzle, or broad statement, the next part of the introduction should pose your main questions and establish your argument. This is your thesis statement—your viewpoint along with the supporting reasons and evidence. It should be articulated plainly so readers understand full well what your paper is about and what it will argue.

After that, give your readers a road map of what’s to come. That’s normally done at the end of the introductory section (or, in a book, at the end of the introductory chapter). Here’s John J. Mearsheimer presenting such a road map in The Tragedy of Great Power Politics . He not only tells us the order of upcoming chapters, he explains why he’s chosen that order and which chapters are most important:

The Plan of the Book The rest of the chapters in this book are concerned mainly with answering the six big questions about power which I identified earlier. Chapter 2, which is probably the most important chapter in the book, lays out my theory of why states compete for power and why they pursue hegemony. In Chapters 3 and 4, I define power and explain how to measure it. I do this in order to lay the groundwork for testing my theory… (John J. Mearsheimer, The Tragedy of Great Power Politics . New York: W. W. Norton, 2001, p. 27)

As this excerpt makes clear, Mearsheimer has already laid out his “six big questions” in the introduction. Now he’s showing us the path ahead, the path to answering those questions.

At the end of the introduction, give your readers a road map of what’s to come. Tell them what the upcoming sections will be and why they are arranged in this particular order.

After having written your introduction it’s time to move to the biggest part: body of a research paper.

We write different types of papers for academic and professional reasons. Research paper is one of the most important papers and it is different from other papers. There are different types of rules for writing a research paper , the first part is the introduction. Through this article, we will try to tell you how to write an introduction for a research paper beautifully.

Introduction

Before starting to write any papers, especially research papers one should know how to write a research paper introduction. The introduction is intended to guide the reader from a general subject to a specific area of study. It establishes the context of the research being conducted by summarizing current understanding and background information on the topic, stating the purpose of the work in the form of a thesis, question, or research problem, Briefly explaining your rationale, your methodological approach, highlight the potential findings your research may reveal, and describe the remaining structure of the paper.

A well-written introduction is imperative since, essentially, you never get a second chance to form a great first impression. The opening passage of your paper will give your audience their introductory impression, almost the rationale of your contention, your composing style, the general quality of your investigation, and, eventually, the legitimacy of your discoveries and conclusions. A vague, disorganized, or error-filled introduction will create a negative impression on the readers. While a brief, engaging, and well-written introduction will begin your readers off considering profoundly your expository abilities, your writing style, and your research approach. 

Tips for Writng an Introduction in Research Paper

Introduce your topic

This is a significant part of how to write an introduction for a research paper. The first task of the introduction is to tell the reader what your topic is and why it is interesting or important. This is usually done with a strong opening hook.

A hook is a strong opening sentence that conveys relevance to your topic. Think of an interesting fact or statistic, a powerful statement, a question, or a brief anecdote that will make readers wonder about your topic.

Describe the context

This introduction varies depending on your approach to your writing. In a more argumentative article, you will explore the general context here. In a more empirical paper, this is a great place to review previous research and determine how your research fits together.

Start briefly, and narrow down

The first thing of a research paper introduction is, to briefly describe your broad parts of research, then narrow in on your specific focus. This will help position your research topic within a broader field, making the work accessible to a wider audience than just experts in your field.

A common mistake when writing a research paper introduction is trying to fit everything in at once. Instead, pace yourself and present each piece of information in the most logical order the reader can understand. Typically, this means starting with the big picture and then gradually getting more specific with the details.

For your research paper introduction, you should first present an overview of the topic and then focus on your specific paper. This “funnel” structure naturally includes all the necessary parts of what should be included in a research paper introduction, from context to appropriate or research gaps and finally to relevance.

State Objective and Importance

Papers abandoned because they “do not demonstrate the importance of the topic” or “lack a clear motivation” often miss this point. Say what you want to achieve and why your readers should want to know whether you achieved it or not.

Quote generously

Once you have focused on the specific topic of your research, you should detail the latest and most relevant literature related to your research. Your literature review should be comprehensive but not too long. Remember, you are not writing a review. If you find your introduction is too long or has too many citations, a possible solution is to cite journal articles, rather than cite all of the individual articles that have been summarised in the journal.

Do not Keep it broad

Try to avoid lengthy introductions. A good target is between 500 and 1,000 words, although checking the magazine’s guidelines and back issues will provide the clearest guidance.

The introduction is not lengthy or detailed; rather, they are initiating actions. Introductions are best when they get to the point: save the details in the body of the document, where they belong.

The most important point of a research paper introduction is that they are clear and easy to understand. Writing at length can be distracting and even make your point harder to understand, so cut out unnecessary words and try to express things in simple terms that everyone understands. understandable.

Check journal condition

Many journals have specific assertions in their author instructions. For example, a maximum of one word may be stated, or instructions may require specific content, such as a supposition statement or a summary of your key findings.

Write the introduction to your research paper at the last moment

Your introduction may appear first in a research paper, but the general advice is to wait to write it until everything else has been written. This makes it easier for you to summarize your article because at this point you know everything you’re going to say. This also eliminates the urge to include everything in the introduction because you don’t want to forget anything.

Additionally, it is especially helpful to write an introduction after your research paper is finished. The introduction and conclusion of a research paper have similar topics and often reflect the structure of each topic. Writing the conclusion is also generally easier thanks to the pace created by writing the rest of the paper, and the conclusion can guide you in writing the introduction.

Make your introduction narrative style

Although not always appropriate for formal writing, using a narrative style in the introduction of your research paper can do a lot to engage readers and engage them emotionally. A 2016 study found that in some articles, using narrative strategies improved how often they were cited in other articles. Narrative style involves making the paper more personal to appeal to the reader’s emotions.

• Use first-person pronouns (I, we, my, our) to show that you are the narrator expressing emotions and feelings in the text setting up the scene. 
• Describe the times and locations of important events to help readers visualize them. 
• Appeal to the reader’s morality, sympathy, or urgency as a persuasive tactic. Again, this style will not be appropriate for all research paper introductions, especially those devoted to scientific research. 

However, for more informal research papers and especially essays, this style can make your writing more interesting or at least interesting, perfect for making readers excited right from the beginning of the article.

Use the CARS model

British scientist John Swales developed a method called the CARS model to “generate a search space” in the introduction. Although intended for scientific papers, this simple three-step structure can be used to outline the introduction to any research paper.

Explain the background of your topic, including previous research. Explain that information is lacking in your topic area or that current research is incomplete.

Explain how your research “fills in” missing information about your topic. 

the research findings and providing an overview of the structure of the rest of the paper, although this does not apply to all research papers, especially those Unofficial documents.

Six Essential Elements of How to Write a Research Paper Introduction

1. topic overview.

Start with a general overview of your topic. Refine your outline until you address the specific topic of your article. Next, mention any questions or concerns you have about the case. Note that you will address these in the article.

2. Previous research

Your introduction is the perfect place to review other findings about your topic. Includes both old and modern scholars. This general information shows that you are aware of previous research. It also presents previous findings to those who may not have that expertise.

3. A justification for your article

Explain why your topic needs to be discussed now. If possible, connect it to current issues. Additionally, you can point out problems with old theories or reveal gaps in current research. No matter how you do it, a good reason will keep readers interested and demonstrate why they should read the rest of your article.

4. Describe the method you used

Tell about your processes to make your writing more trustworthy. Identify your goals and the questions you will answer. Reveal how you conducted the research and describe how you measured the results. Also, explain why you made the important choices.

5. A thesis statement

Your main introduction should end with a thesis statement. This statement summarises the ideas that will run throughout your entire research paper. It must be simple and clear.

6. An outline

It is an adequate idea of how to write an introduction for a research paper. 

The introduction usually ends with an overview. Your layout should quickly present what you plan to cover in the following sections. Think of it as a road map, guiding readers to the end of your article.

What is the purpose of the introduction in a research paper, and why is it considered crucial?

The purpose of the introduction in a research paper is to guide the reader from a general subject to a specific area of study. It establishes the context of the research by summarizing current understanding, stating the purpose of the work, explaining the rationale and methodological approach, highlighting potential findings, and describing the paper’s structure. It’s considered crucial because it forms the reader’s first impression and sets the tone for the rest of the paper.

How can I effectively use a hook to engage readers in my research paper introduction?

Using a hook, such as an interesting fact, a powerful statement, a question, or a brief anecdote, can effectively engage readers in your research paper introduction. A hook captures the reader’s attention and makes them curious about your topic, encouraging them to continue reading.

How long the introduction should be in a research paper?

While there’s no strict word count, a good target for a research paper introduction is between 500 and 1,000 words, although you should check the specific guidelines provided by the journal you’re submitting to. It’s recommended to write the introduction after the rest of the paper has been completed. This way, you have a comprehensive understanding of your research, making it easier to summarize and guide your readers effectively.

Conclusion 

These are the important tips and tricks on how to write an introduction for a research paper properly. If you maintain these rules we believe that you will be able to write an excellent introduction in your research paper.

6 Examples of Research Paper Introductions to Hook Your Readers

Welcome to our guide on research paper introductions!

As you may already know, the introduction is a critical component of any research paper, as it sets the tone for the rest of the paper and establishes the reader’s expectations.

The introductory paragraph in a research paper should give an overview of what the reader can expect from the rest of the paper.

It should also establish a context for readers who are new to this topic. More importantly, when writing a research paper introduction, it’s best to focus on two key points: the problem being addressed and how this particular study (or studies) addresses it.

If those two points are clear then readers should be able to follow along as they read more into your paper.

In the following sections, we’ll provide you with examples of different types of research paper introductions to help you get started.

Types of Research Paper Introductions

General introductions.

A general introduction is suitable when you’re discussing a range of different topics or subjects within one paper. It provides the reader with an idea of where you stand in regard to the topic at hand and can be followed up with a sentence or two explaining your specific angle.

Topic: The Effect of Social Media on Mental Health

Social media has become an integral part of our daily lives, and its impact on mental health has become a subject of increasing concern in recent years. While social media platforms have provided a new means of communication and access to information, they have also been linked to negative mental health outcomes such as depression, anxiety, and low self-esteem. This research paper aims to explore the relationship between social media use and mental health outcomes. Specifically, we will investigate how social media affects individuals’ perceptions of themselves and their social relationships, as well as the potential impact on their emotional well-being. Through a thorough literature review and original research, we hope to shed light on the complex relationship between social media and mental health and provide insights into effective interventions for those who may be negatively impacted by social media use.

Topic: Formal Presentations at University

Most universities require their graduate-level courses to have some form of formal presentation such as a dissertation, master’s thesis, or doctoral dissertation. These presentations often take the form of an oral defense. Formal presentations provide both teachers and students with feedback in order to make future projects better. Teachers also use these projects to gauge student performance and provide guidance during group discussions throughout the course. What makes these oral defenses different than others is that they must adhere to strict guidelines set forth by the institution overseeing them. Failure to comply with these guidelines may result in expulsion from the university. Oral defenses typically contain three major parts: an opening statement, main body, and closing statement. However, some institutions may offer variations of this format. For instance, many institutions now require a written version of the presentation that includes all major aspects required by the institution.

Quote-Based Research Paper Introduction

This type of introduction is ideal for research papers that rely heavily on quotes to establish their point.

In these cases, quoting the most relevant piece of information is usually necessary because doing so will allow the reader to better understand what your discussion entails.

With that said, remember that every quote you include needs to add something significant and/or novel which hasn’t been covered before – otherwise it won’t be worth including in your paper!

Topic: International Student Success at the University Level

Shakespeare once said that “A rose by any other name would smell as sweet.” This line from Romeo and Juliet suggests that names don’t matter. Similarly, the fact that someone goes to school in a certain country does not affect the quality of education. Yet research has shown that international students perform worse academically than domestic ones in American colleges and universities. So, the question becomes: How do we foster success among international students? It is possible that differences in culture and socialization contribute to the observed gaps in academic achievement. Given that, our next step should be to examine the challenges faced by international students in an effort to find effective ways of addressing these challenges.

Topic: The Impact of Social Media on Mental Health

As Mark Twain once said, “Comparison is the death of joy.” In today’s world, social media platforms provide us with countless opportunities to compare our lives to those of others, often leading to feelings of inadequacy, anxiety, and depression. Research has shown that excessive social media use can have a negative impact on mental health, particularly among young adults. Given the increasing prevalence of social media in our daily lives, it’s important to explore this topic in more depth and understand the ways in which social media use can impact mental health outcomes.

Surprising Fact-based Introductions

A surprising fact-based introduction works well with scientific or medical topics where there is surprising new evidence that directly impacts how people view a certain issue. In such cases, it’s often necessary to give some background on what exactly is at stake in order to highlight why it’s important and relevant. Following that, you can introduce the key findings and what they mean.

Topic: The relationship between caffeine and weight loss

Caffeine is a well-known stimulant, which is consumed by millions of people on a daily basis in the form of coffee, tea, energy drinks, or pills. Although it’s unclear how much caffeine is too much for an individual to consume each day, it’s commonly believed that the positive effects of caffeine are canceled out by the increased appetite that results from drinking caffeinated beverages. But did you know that caffeine might actually help you lose weight?! Recent research conducted by a team of investigators from the Johns Hopkins Bloomberg School of Public Health and Harvard T.H. Chan School of Public Health found that the more caffeine an individual consumes, the lower their risk for obesity. That’s right: while it may sound counterintuitive, having one or two cups of coffee per day could actually decrease your chances of becoming overweight or obese.

Topic: The Benefits of Napping on Memory Retention

Did you know that a short nap can help boost your memory retention by up to 30%? Most people think of napping as something reserved for children or lazy adults, but recent research has shown that a short nap can actually be beneficial for cognitive function, particularly in regard to memory. In today’s fast-paced world, we often prioritize productivity over rest, but the science behind napping suggests that we should be doing the opposite. In this paper, we will explore the benefits of napping on memory retention and discuss how individuals and organizations can incorporate napping into their daily routines for optimal cognitive performance.

Explanatory research paper introductions

These types of research paper introductions are used when you’re introducing a new concept or idea that requires the audience to have knowledge of basic facts in order to follow along.

In this case, it’s critical that you provide the necessary background information and then follow up with a statement about why the rest of the research is interesting and/or relevant.

For example, you might say that the paper discusses a recent study on mindfulness and meditation.

In order to fully grasp the research and the claims being made, it’s necessary to first understand what mindfulness is and why it’s relevant. The following paragraphs would therefore serve as an introduction to both topics.

Topic: Mindfulness

Mindfulness is a mental state achieved by focusing one’s awareness on the present moment, while calmly acknowledging and accepting one’s feelings, thoughts, and bodily sensations. Regular practice of mindfulness can be highly beneficial to both mental and physical health. There are many different techniques for practicing mindfulness: Mindful walking, sitting with an open mind, eating without distractions, listening deeply to others, or simply noticing what you see in your environment. What’s most important is that you develop the ability to pay attention in a way that helps you connect with yourself and the world around you. And just like anything else, mindfulness takes practice. The best way to get started is by taking part in a course or program offered at your local community center, hospital, or online.

Topic: The Effectiveness of Online Learning in Higher Education

As more and more students turn to online learning to pursue their higher education, questions have arisen regarding the effectiveness of this type of education. While online learning offers a number of benefits, such as flexibility and convenience, it also presents unique challenges, including the lack of face-to-face interaction with instructors and classmates. This research paper aims to examine the effectiveness of online learning in higher education and compare it to traditional classroom-based learning. By conducting a literature review and analyzing data from surveys and interviews with students and instructors, this paper seeks to identify the advantages and disadvantages of online learning and provide recommendations for improving its effectiveness.

Narration-based paper introductions

This type of research paper introduction is used when you’re discussing a topic or event in detail.

You could talk about why it’s important, explain what happened and how it relates to your larger point, summarize what happened (as with a timeline), or present an example to prove your thesis.

Whatever you choose, it’s imperative that you make your readers want to keep reading.

This is done by telling a compelling story, using storytelling elements such as tension and conflict, or painting a vivid picture of the scene with sensory details.

Topic: The impact of stress on memory and learning

It’s well known that stress can impair our ability to learn new things, but it also has an impact on our memories. Well, I have first-hand experience with this. The night before my midterm, I had a major fight with my partner. This was one of the worst arguments we’ve ever had and it went on for hours. Needless to say, it stressed me out and there’s no doubt that it hurt my performance on the test. The funny thing is that in the days following the argument, my partner and I were able to clear everything up, so now we’re good again. But this experience taught me one very important lesson: the impact of stress on memory and learning might seem negligible but it can actually have a long-term impact on academic performance.

Topic: The Effects of Social Media on Mental Health

As I sit here scrolling through my Instagram feed, I can’t help but feel a sense of envy and inadequacy wash over me. The seemingly perfect lives of influencers and friends alike are on full display, leaving me to question why I don’t have the same level of success and happiness. It’s no secret that social media has become a ubiquitous part of our daily lives, with billions of people using platforms like Instagram, Facebook, and Twitter to connect with others and share their lives. But what are the effects of this constant exposure to other people’s carefully curated images and narratives? Are we putting ourselves at risk for developing mental health issues like anxiety and depression? In this paper, I will explore the research that has been done on the topic of social media and mental health, examining both the positive and negative effects that social media can have on our psychological well-being. By the end of this paper, you will have a better understanding of how social media impacts mental health and what steps we can take to mitigate its negative effects.

Teaser-based research paper introductions

The most common types of research paper introductions are teasers.

This simply means that your first sentence is a hook: something to grab your reader’s attention and make them want to read more.

One way to create a compelling teaser is by addressing an interesting question or controversial topic, such as “Why do some people succeed and others fail?”

Another approach is to pose a problem that you plan to solve.

Here are examples of a teaser-based research paper introductions.

Topic: Why do some people succeed and others fail?

Failure is a part of life. We all fail at one time or another, it’s just something that happens. But why do some people fail more than others? And what about people who never seem to fail? You see them every day, they are in your office and everywhere else you go. These people always seem to be successful and highly driven. How do they do it? This is a question that has puzzled psychologists and other social scientists for years. In the past, a lot of psychologists believed that success was due to differences in abilities and intelligence. Others said it depended on luck. Still, others believed that family background determined whether someone succeeded or not. As you can imagine, these explanations led to considerable debate and disagreement among scholars.

Topic: The Future of Artificial Intelligence in Healthcare

Are we on the cusp of a revolution in healthcare? With the rise of artificial intelligence (AI), the answer might just be yes. From machine learning algorithms that can identify diseases faster and more accurately than humans to chatbots that can answer patient questions 24/7, AI is poised to transform every aspect of healthcare. But as with any technology, there are risks and challenges that must be addressed. In this paper, we’ll explore the ways in which AI is being used in healthcare today and the potential implications for patients, doctors, and the healthcare industry as a whole. Buckle up, because the future is here, and it’s powered by AI.

Final Remarks: Research Paper Introductions

Crafting an effective research paper introduction can be challenging, but with the right approach and attention to detail, you can create an introduction that captures the reader’s attention and sets the stage for the rest of the paper.

Whether you choose a general introduction, a quote-based introduction, a surprising fact-based introduction, or an anecdotal introduction, be sure to clearly state your topic and thesis, provide background information, and engage your readers in meaning.

How to Write an Introduction for a Research Paper

• Purpose of intro
• Key elements
• Writing an effective intro
• Step-by-step guide
• Research intro checklist
• Introduction formats
• Good and bad examples

An introductory paragraph is vital for any academic paper. It allows you to show reviewers why your research topic is worth reading about. In this article, we will explore the tips to make a good introduction paragraph. You’ll get a step-by-step tutorial on writing your paper’s informative yet laconic intro.

What is the purpose of an introduction?

The purpose of a research paper intro is to provide an overview and context for the study being conducted. A research paper engages the reader, establishes the importance of the research topic, and outlines the study’s objectives and scope.

The paper intro also presents the question or hypothesis and summarizes relevant background characteristics and existing literature.

An effective introduction helps the reader understand the significance and relevance of the research paper and sets the stage for the subsequent sections. The introduction captures the reader’s attention and creates a foundation for understanding the research and its contributions.

The key elements of a scientific paper introduction

The introduction of your research paper should include several key elements, including the problem statement, hypothesis/thesis/research question, purpose, and background.

Let’s explore each of these parts of the research paper intro in detail:

• Problem Statement : identifies the specific issue or gap in knowledge that the research paper aims to address. It highlights the problem’s relevance, significance, and potential impact on the field of study. The problem statement sets the stage for the research by clearly stating the project or research gap.
• Hypothesis / Thesis / Research Question : a paper hypothesis predicts the relationship between variables, a thesis statement presents the main argument or claim, and a research question seeks to put a specific aspect on a research paper.
• Purpose: describes the overall objective or goal the research paper aims to achieve. It outlines the researcher’s intention and provides a clear direction for the investigation. The purpose statement typically explains why the research is being conducted and what the researcher hopes to accomplish by the end of the study.
• Background : provides the necessary context and information to familiarize readers with the research paper. It presents a concise review of the relevant literature, previous studies, and theoretical frameworks that have shaped the understanding of the problem.

Shortly, the introduction section of a research paper combines these key elements to introduce the problem, state the hypothesis/thesis/research question, define the paper’s purpose, and provide the background necessary for readers to understand the significance and context of the study.

How to write an effective intro?

To start an introduction for a research paper, consider the following steps:

• Hook the reader : begin with a compelling opening sentence or a thought-provoking statement that grabs the reader’s attention. This could be an interesting fact, a relevant anecdote, or a surprising statistic related to your research paper.
• Provide background information : offer a brief overview of the paper and its significance in the field. This helps to improve the structure of an introduction and demonstrate why it is important to investigate the point further in a paper.
• State the problem : clearly articulate the problem statement or research gap your study aims to address. Explain the specific issue or gap in knowledge that your research paper seeks to explore, emphasizing its relevance and potential impact.
• Present the research question/hypothesis/thesis : formulate a concise and focused research question, hypothesis, or thesis statement in the intro that guides your scientific paper. This sets the direction for your research and provides a clear focus for the reader.
• Outline the purpose and objectives : explain the overall purpose of your research paper and the specific objectives you aim to achieve. This helps readers understand why your study is being conducted and what you hope to accomplish.
• Preview the structure : briefly introduce the organization and structure of your research paper. Mention the main sections or components that will be covered, giving readers a sense of what to expect as they continue reading the paper.

Remember, the intro should be concise and engaging, providing a clear roadmap for your research and capturing the reader’s interest from the very beginning. There are different ways to start a research paper, and you can pick the intro that suits you best.

Writing an introduction to a research paper: key steps

Here’s a short guide on getting you started with an introduction:

• Start with an attention-grabbing opening : begin your intro with a captivating statement, a relevant quote, a surprising fact, or an intriguing anecdote. This will engage the reader’s interest and make them curious about your research paper.
• Provide background information : write a brief overview of the research topic to provide context and establish the importance of the subject matter. Discuss key concepts, definitions, or historical background relevant to your study. This section should help the reader understand the broader context of your research paper.
• State the research problem or gap : clearly define the specific problem or research gap your study aims to address. Explain why this problem is significant and deserving of investigation. This helps the reader understand the purpose and relevance of your research paper.
• Present your research question or thesis statement : formulate a clear and concise research question, hypothesis, or thesis statement that serves as the central focus of your study. This statement should guide your research paper and articulate your introduction format.
• Outline the structure of the paper : write a brief preview of your research paper’s main sections and organization. This helps the reader understand the flow of your paper and what to expect in each section. Provide a roadmap by mentioning the key points or arguments discussed in subsequent sections.

By following these steps, you can create an introduction that grabs the reader’s attention and sets the stage for the rest of your research paper, clearly understanding your study’s problem, purpose, and structure.

Writing a checklist for a proper college paper introduction

Here’s a short writing checklist for a research paper intro:

• Attention-grabbing opening:
• Does the research paper introduction example start with a compelling statement, relevant quote, surprising fact, or intriguing anecdote?
• Is the opening engaging enough to capture readers’ attention and make them curious about the research paper?
• Background information:
• Have you provided a concise overview of the research topic, including relevant definitions, concepts, or historical context?
• Does the background information help the reader understand the broader context and importance of the subject matter?
• Clear problem statement:
• Have you clearly stated the specific problem or research gap that your study aims to address?
• Does a research introduction have a well-defined, strong, and significant problem statement?
• Research question or thesis statement:
• Have you presented a clear and concise research question, hypothesis, or thesis statement that guides your paper?
• Does the research question or thesis statement align with the problem statement and set the direction for your research paper?
• Structure and organization:
• Did you write a brief overview of the structure and organization of the research paper?
• Does the introduction outline the main sections or components covered in the paper?
• Coherence and flow:
• Is the intro logically organized? Does it have smooth transitions between ideas and paragraphs?
• Does the intro flow smoothly from the opening to the problem statement, research question, and purpose?
• Conciseness and clarity:

• Is the language clear, avoiding jargon or overly technical terms that may confuse the reader?
• Relevance and significance:
• Have you clearly explained the relevance and significance of the research topic and the paper’s potential impact?
• Does the introduction effectively communicate why your research is important and worth exploring?

This checklist will help you to review your research essay introduction to ensure it effectively grabs the reader’s attention, provides necessary background information, states the problem clearly, presents a focused research question or thesis statement, outlines the structure of the paper, and maintains coherence and clarity throughout.

Types of intro formats

Different academic disciplines may follow specific formatting styles for research introduction, such as MLA (Modern Language Association), APA (American Psychological Association), Chicago, ASA (American Sociological Association), and AMA (American Medical Association).

To write an introduction paragraph, you should understand the differences between the most common academic formats for your future paper.

MLA (Modern Language Association):

• Primarily used in humanities, literature, and arts disciplines.
• Features in-text citations using the author-page format (e.g., “Smith 45”).

APA (American Psychological Association):

• Commonly used in social sciences, psychology, and education.
• Utilizes in-text citations with the author-date format (e.g., “Smith, 2019”).
• Often used in history, humanities, and some social sciences.
• Offers two styles: the notes-bibliography system and the author-date system.
• Includes a bibliography page to list all sources used.

ASA (American Sociological Association):

• Primarily used in sociology and related social sciences.
• Utilizes in-text citations with the author-date format (e.g., “Smith 2019”).

AMA (American Medical Association):

• Commonly used in medical, health, and biological sciences.
• Features in-text citations with a superscript number (e.g., “Smith^1”).
• Emphasizes accuracy and consistency in citation style.

All formatting styles mean a set of rules and guidelines for citing sources, formatting headings, page layout, and referencing. It’s important to consult the specific style guide or manual associated with your field of study before you write.

These might include guidelines provided by your institution to ensure proper paper formatting and adherence of a research introduction to the chosen style.

Research introduction sample

Now that you know how the idea goes in the introduction of a research paper, let’s see the practical examples of good and bad introductions and discuss their differences.

Good example:

Title: “Exploring the Impact of Climate Change on Biodiversity: A Comprehensive Analysis”

Introduction:

Climate change is a pressing global issue that has far-reaching consequences for our planet. Its effects on various ecosystems, particularly biodiversity loss, have attracted significant attention from researchers and policymakers alike.

This research paper aims to provide a comprehensive analysis of the impact of climate change on biodiversity, focusing on key regions and species vulnerable to these changes. By examining the latest scientific literature, empirical studies, and expert opinions, we will explore the complex interplay between climate change and biodiversity loss, shed light on the underlying mechanisms, and propose potential mitigation strategies.

Understanding these dynamics is crucial for developing effective conservation strategies and promoting sustainable practices that will help preserve our planet’s invaluable natural heritage.

Bad example:

Title: “Climate Change and Biodiversity”

Climate change and biodiversity are two important topics that have received considerable attention recently. Climate change refers to the long-term alteration of temperature and precipitation patterns, while biodiversity encompasses the variety of life forms found on Earth.

In this research paper, we will discuss the impact of climate change on biodiversity and explore various examples and case studies. The paper will also highlight the significance of addressing this issue and present potential solutions.

By delving into this subject, we aim to contribute to the existing body of knowledge and raise awareness about the importance of protecting biodiversity in climate change.

To begin an introduction paragraph, don’t provide too much background or theory at once. Remember to arrange your thoughts concisely while keeping the important information for the paper body.

A good intro should answer the four basic questions:

• What was I studying?
• Why was this topic important to investigate?
• What did we know about this topic before I did this study?
• How will this study advance our knowledge?

Remember that you might not get a second chance to create a positive first impression. That’s why it’s equally important to keep your paper laconic and to end an introduction paragraph with a call to action to read your research paper.

• Research Paper Title
• Research Paper Sources
• Research Paper Problem Statement
• Research Paper Thesis Statement
• Hypothesis for a Research Paper

Research Paper Introduction – Definition

The research paper introduction arrests the reader’s attention from a general perspective to one specific area of a study. It outlines a summary of the research being conducted by condensing current understanding and background information about the topic, presenting the importance of the research in the form of a hypothesis, research questions , or research problem. It also outlines the methodological approach touching the likely outcomes that your study can reveal, and describing the remaining structure of the research paper.

Research paper introduction in academic writing is widely used in the presentation of a thesis and academic work. This article highlights the best ways to go about writing a captivating introduction to help you fine-tune your writing skills at the introductory level.

What is the purpose of a research paper introduction?

It establishes the depth, the context, and the importance of the research by summarizing and bringing the reader’s attention to your thesis. The research topic should be clear from the get-go. The introduction needs to draw in the reader whilst summarizing for them what it is that they’re about to read.

How do you start a research paper introduction?

You start the introduction of the research paper by presenting what your research paper is about. You’ll need some great sentence starters and transition words because your introduction needs to be well written in order to envoke the reader’s interest. Don’t forget to create some context and inform the reader about the research you have carried out.

How do you write a research paper introduction?

Draft your introduction on a piece of paper and edit it extensively before you add it to the final copy of your research paper. Be sure to refer to the research paper outline that you created before you started writing. Your sentences should be short and precise. It’s also important that you do not oversell your ideas at this point- remember that you’re still trying to draw the reader in.

What do you include in a research paper introduction?

You should highlight the key aspects of your thesis. It’s important that your thesis statement is placed towards the end of your research paper introduction. You are essentially briefly introducing the reader to concepts that they will come across in your research work.

How do you write a research paper introduction to a scientific research paper?

The information included in a scientific research paper introduction is very similar to what you would include in any other research paper . However, the overall structure of a scientific research paper is a bit different as you’ll need to include sections like ‘materials’ and ‘scientific processes’. Your introduction to a scientific research paper should highlight sufficient background information on the experiment that you did, making it easy for readers to understand and evaluate your research work.

What is the rationale in the research paper introduction?

The rationale for research is the highlight of why your research topic is worthy of the study and experimentation and how it adds value to already existing research works. You will probably need to bury yourself in books, do your research in the library and undertake descriptive research for your specific field. You need to become an expert in your chosen field and you should know exactly what you are contributing to the academic community with your research.

Tip: Read about the different parts of a research paper for a full rundown of which parts go where.

Research Paper Introduction: Structure

The structure of a research paper introduction should contain the main goal and the objective of the research. It should be a concise but enlightening outline of the soon-after context. Here you are required to state your rationale or reasons why you want to major into a particular subject or instead what problems you seek to solve in the subject matter.

Therefore, you need  comprehensible argumentation to emphasize the importance of your research topic to your reader. In addition, you want to excite the readers curiosity for the subject. Below you will find the prime points to create a convincing research paper introduction.

The Do’s and Don’ts

One of the things that should be evident throughout your research paper introduction is honesty to your readers. This will go a long way in establishing a piece of research work that can be relied on by other students and researchers in the future. You will also not find it hard explaining the rest of the research paper to the panellists.

• Your research paper introduction should be short, accurate and precise. Don´t tell stories at the introductory level of your research.

• Pick-point the ideas you want to talk about and the methodologies that you have derived from the course work for you to solve the hindrances that you encountered on the ground.

• Refer to diverse research paper introduction works and make sure to look for up-to-date researches for your thesis.

• Provide tangible shreds of evidence and supporting arguments to blueprint your findings, and at least prove the fact that what you are presenting is well researched as well as authentic.

• Find it worth to include relevant terms, may it be scientific or mathematical or even theological.

• Always remember to proofread your work.

• Scrutinize your research paper introduction before presentation for reliability and present it with utmost logic to show how it supports your research and not a mere throwing in of figures.

• Do not try explaining ideas that do not answer your research questions. This is a mere waste of time and will not lead to any new conclusion about your research paper introduction work.

• Do not write a lengthy research paper introduction. What will you write in the rest of the paper if you tell it all here?

• Do not state incomplete reasons for carrying out the research. You want to be as convincing as possible in your research paper introduction.

• Do not exceed the stated word limit. It brings about the fact that you do not know what you are talking about, instead, you present yourself as a bluff.

• Do not plagiarize your research paper introduction, just like any other portion of your research work. Check this before any submissions. Make sure all the hypothetical findings are genuine and unique.

Research Paper Introduction: Example

In a nutshell

• Research paper introduction introduces the core topic to your thesis.
• The introduction explains where you are coming from concerning your research. Therefore make your research paper introduction precise.
• The research paper introduction should be short, concise, and accurate.
• Your research paper introduction should highlight the rationale of your research, which is the support of the worthiness of your study and research experiments.
• A research paper introduction should be free from plagiarism.

The Dreaded Introductory Paragraph

Writing the introductory paragraph can be a frustrating and slow process -- but it doesn't have to be.  If you planned your paper out, then most of the introductory paragraph is already written.  Now you just need a beginning and an end.

Here's an introductory paragraph for a paper I wrote.  I started the paper with a factoid, then presented each main point of my paper and then ended with my thesis statement.

How to Write a Research Paper | A Beginner's Guide

A research paper is a piece of academic writing that provides analysis, interpretation, and argument based on in-depth independent research.

Research papers are similar to academic essays , but they are usually longer and more detailed assignments, designed to assess not only your writing skills but also your skills in scholarly research. Writing a research paper requires you to demonstrate a strong knowledge of your topic, engage with a variety of sources, and make an original contribution to the debate.

This step-by-step guide takes you through the entire writing process, from understanding your assignment to proofreading your final draft.

Table of contents

Understand the assignment, choose a research paper topic, conduct preliminary research, develop a thesis statement, create a research paper outline, write a first draft of the research paper, write the introduction, write a compelling body of text, write the conclusion, the second draft, the revision process, research paper checklist, free lecture slides.

Completing a research paper successfully means accomplishing the specific tasks set out for you. Before you start, make sure you thoroughly understanding the assignment task sheet:

• Read it carefully, looking for anything confusing you might need to clarify with your professor.
• Identify the assignment goal, deadline, length specifications, formatting, and submission method.
• Make a bulleted list of the key points, then go back and cross completed items off as you’re writing.

Carefully consider your timeframe and word limit: be realistic, and plan enough time to research, write, and edit.

Prevent plagiarism. Run a free check.

There are many ways to generate an idea for a research paper, from brainstorming with pen and paper to talking it through with a fellow student or professor.

You can try free writing, which involves taking a broad topic and writing continuously for two or three minutes to identify absolutely anything relevant that could be interesting.

You can also gain inspiration from other research. The discussion or recommendations sections of research papers often include ideas for other specific topics that require further examination.

Once you have a broad subject area, narrow it down to choose a topic that interests you, m eets the criteria of your assignment, and i s possible to research. Aim for ideas that are both original and specific:

• A paper following the chronology of World War II would not be original or specific enough.
• A paper on the experience of Danish citizens living close to the German border during World War II would be specific and could be original enough.

Note any discussions that seem important to the topic, and try to find an issue that you can focus your paper around. Use a variety of sources , including journals, books, and reliable websites, to ensure you do not miss anything glaring.

Do not only verify the ideas you have in mind, but look for sources that contradict your point of view.

• Is there anything people seem to overlook in the sources you research?
• Are there any heated debates you can address?
• Do you have a unique take on your topic?
• Have there been some recent developments that build on the extant research?

In this stage, you might find it helpful to formulate some research questions to help guide you. To write research questions, try to finish the following sentence: “I want to know how/what/why…”

A thesis statement is a statement of your central argument — it establishes the purpose and position of your paper. If you started with a research question, the thesis statement should answer it. It should also show what evidence and reasoning you’ll use to support that answer.

The thesis statement should be concise, contentious, and coherent. That means it should briefly summarize your argument in a sentence or two, make a claim that requires further evidence or analysis, and make a coherent point that relates to every part of the paper.

You will probably revise and refine the thesis statement as you do more research, but it can serve as a guide throughout the writing process. Every paragraph should aim to support and develop this central claim.

Receive feedback on language, structure, and formatting

Professional editors proofread and edit your paper by focusing on:

• Academic style
• Vague sentences
• Style consistency

See an example

A research paper outline is essentially a list of the key topics, arguments, and evidence you want to include, divided into sections with headings so that you know roughly what the paper will look like before you start writing.

A structure outline can help make the writing process much more efficient, so it’s worth dedicating some time to create one.

Your first draft won’t be perfect — you can polish later on. Your priorities at this stage are as follows:

• Maintaining forward momentum — write now, perfect later.
• Paying attention to clear organization and logical ordering of paragraphs and sentences, which will help when you come to the second draft.
• Expressing your ideas as clearly as possible, so you know what you were trying to say when you come back to the text.

You do not need to start by writing the introduction. Begin where it feels most natural for you — some prefer to finish the most difficult sections first, while others choose to start with the easiest part. If you created an outline, use it as a map while you work.

Do not delete large sections of text. If you begin to dislike something you have written or find it doesn’t quite fit, move it to a different document, but don’t lose it completely — you never know if it might come in useful later.

Paragraph structure

Paragraphs are the basic building blocks of research papers. Each one should focus on a single claim or idea that helps to establish the overall argument or purpose of the paper.

Example paragraph

George Orwell’s 1946 essay “Politics and the English Language” has had an enduring impact on thought about the relationship between politics and language. This impact is particularly obvious in light of the various critical review articles that have recently referenced the essay. For example, consider Mark Falcoff’s 2009 article in The National Review Online, “The Perversion of Language; or, Orwell Revisited,” in which he analyzes several common words (“activist,” “civil-rights leader,” “diversity,” and more). Falcoff’s close analysis of the ambiguity built into political language intentionally mirrors Orwell’s own point-by-point analysis of the political language of his day. Even 63 years after its publication, Orwell’s essay is emulated by contemporary thinkers.

Citing sources

It’s also important to keep track of citations at this stage to avoid accidental plagiarism . Each time you use a source, make sure to take note of where the information came from.

The research paper introduction should address three questions: What, why, and how? After finishing the introduction, the reader should know what the paper is about, why it is worth reading, and how you’ll build your arguments.

What? Be specific about the topic of the paper, introduce the background, and define key terms or concepts.

Why? This is the most important, but also the most difficult, part of the introduction. Try to provide brief answers to the following questions: What new material or insight are you offering? What important issues does your essay help define or answer?

How? To let the reader know what to expect from the rest of the paper, the introduction should include a “map” of what will be discussed, briefly presenting the key elements of the paper in chronological order.

The major struggle faced by most writers is how to organize the information presented in the paper, which is one reason an outline is so useful. However, remember that the outline is only a guide and, when writing, you can be flexible with the order in which the information and arguments are presented.

One way to stay on track is to use your thesis statement and topic sentences . Check:

• topic sentences against the thesis statement;
• topic sentences against each other, for similarities and logical ordering;
• and each sentence against the topic sentence of that paragraph.

Be aware of paragraphs that seem to cover the same things. If two paragraphs discuss something similar, they must approach that topic in different ways. Aim to create smooth transitions between sentences, paragraphs, and sections.

The research paper conclusion is designed to help your reader out of the paper’s argument, giving them a sense of finality.

Trace the course of the paper, emphasizing how it all comes together to prove your thesis statement. Give the paper a sense of finality by making sure the reader understands how you’ve settled the issues raised in the introduction.

You might also discuss the more general consequences of the argument, outline what the paper offers to future students of the topic, and suggest any questions the paper’s argument raises but cannot or does not try to answer.

You should not :

• Offer new arguments or essential information
• Take up any more space than necessary
• Begin with stock phrases that signal you are ending the paper (e.g. “In conclusion”)

There are four main considerations when it comes to the second draft.

• Check how your vision of the paper lines up with the first draft and, more importantly, that your paper still answers the assignment.
• Identify any assumptions that might require (more substantial) justification, keeping your reader’s perspective foremost in mind. Remove these points if you cannot substantiate them further.
• Be open to rearranging your ideas. Check whether any sections feel out of place and whether your ideas could be better organized.
• If you find that old ideas do not fit as well as you anticipated, you should cut them out or condense them. You might also find that new and well-suited ideas occurred to you during the writing of the first draft — now is the time to make them part of the paper.

The goal during the revision and proofreading process is to ensure you have completed all the necessary tasks and that the paper is as well-articulated as possible. You can speed up the proofreading process by using the AI proofreader .

Global concerns

• Confirm that your paper completes every task specified in your assignment sheet.
• Check for logical organization and flow of paragraphs.
• Check paragraphs against the introduction and thesis statement.

Fine-grained details

Check the content of each paragraph, making sure that:

• each sentence helps support the topic sentence.
• no unnecessary or irrelevant information is present.
• all technical terms your audience might not know are identified.

Next, think about sentence structure , grammatical errors, and formatting . Check that you have correctly used transition words and phrases to show the connections between your ideas. Look for typos, cut unnecessary words, and check for consistency in aspects such as heading formatting and spellings .

Finally, you need to make sure your paper is correctly formatted according to the rules of the citation style you are using. For example, you might need to include an MLA heading  or create an APA title page .

A research paper introduction holds perhaps the most importance for a study to be successful. After a good research paper abstract , it is the introduction that builds the interest in a reader to continue reading the research paper. If the introduction turns out to be dull and drab, then the study would be a failed one.

A good research paper needs a lot of background study, which you often fail to do. To make your work easier, Management Paper is there for you to help you write yours efficiently.

Key Features of a Research Paper Introduction

• It forms the basic part of both the research paper as well as the research proposal .
• Apart from giving a general notion about the research paper topic , it includes important elements such as background, aim, objectives, questions and many more.
• It must contain the questions ‘WHY’: why is the research conducted, why it is important, why this chosen topic and so on is.
• It helps in pointing out the knowledge gaps and fills them up throughout the paper.
• Use precise and clear points.

The Most Commonly Included Elements in The Research Papers

There are different kinds of research papers like essays, reports, dissertations and journals. The introduction which is generally used in case of all other types of research paper except dissertations are similar in nature. Such an introduction is similar to a summary of the topic, defining the problem, stating the aims and objectives that are going to be established through the research.

But in case of dissertation, in a good research paper format the introduction is presented in great detail by dividing the section into the following parts:

• Research background
• Research problem
• Research rationale
• Research aim
• Research objectives
• Research hypothesis
• Research questions

Apart from this, many papers include time plan, scope and limitations of the research too. The experts from the team of Management Paper can help you with your paper writing and also make you understand the various aspects of a research paper.

Some Significant Examples of Research Paper Introduction

Research paper introduction example #1, topic: impact of leadership effectiveness on employees for the company amazon (dissertation).

The history and the various past events related to the topic are being mentioned in this section. Thsi supplies context to the paper and contains both relevant and important studies. Authenticating your information is a must by in-text citations.

The research problem states a specific area of concern, a bothering question, a difficulty which is to be eliminated or a condition that demands improvement. The missing knowledge about the topic is being found out through this and then only you can do further research about the problem.

The rationale answers the question of why the research is being conducted and thus states its importance.

The things that are expected to be achieved at the end of the research are generally mentioned here.

The objectives are the various goals or targets that are to be established and achieved throughout the study.

The research question points out the facts that are to be established through the paper and provides the research with a clear focus and purpose.

This is a specific predictive statement about the possible future outcome of the study which is mostly based upon the relationship between different variables or on a single variable.

Research Paper Introduction Example # 2

Topic: implementing online customer support service through chat portal at aldi, research paper introduction example # 3, topic: compare and contrast the policies for the aged people in various countries.

In both the second and the third example, the introduction is written in a single paragraph. In the first line itself you must introduce the topic. Try to avoid embellishments. Write any remarkable event about the topic then. Explain the problem and the purpose of the research. Try to build a reasonable thesis statement. Then with few lines, insert a smooth transition to make a shift from the introduction to the body.

Research Paper – Structure, Examples and Writing Guide

Table of Contents

Research Paper

Definition:

Research Paper is a written document that presents the author’s original research, analysis, and interpretation of a specific topic or issue.

It is typically based on Empirical Evidence, and may involve qualitative or quantitative research methods, or a combination of both. The purpose of a research paper is to contribute new knowledge or insights to a particular field of study, and to demonstrate the author’s understanding of the existing literature and theories related to the topic.

Structure of Research Paper

The structure of a research paper typically follows a standard format, consisting of several sections that convey specific information about the research study. The following is a detailed explanation of the structure of a research paper:

The title page contains the title of the paper, the name(s) of the author(s), and the affiliation(s) of the author(s). It also includes the date of submission and possibly, the name of the journal or conference where the paper is to be published.

The abstract is a brief summary of the research paper, typically ranging from 100 to 250 words. It should include the research question, the methods used, the key findings, and the implications of the results. The abstract should be written in a concise and clear manner to allow readers to quickly grasp the essence of the research.

Introduction

The introduction section of a research paper provides background information about the research problem, the research question, and the research objectives. It also outlines the significance of the research, the research gap that it aims to fill, and the approach taken to address the research question. Finally, the introduction section ends with a clear statement of the research hypothesis or research question.

Literature Review

The literature review section of a research paper provides an overview of the existing literature on the topic of study. It includes a critical analysis and synthesis of the literature, highlighting the key concepts, themes, and debates. The literature review should also demonstrate the research gap and how the current study seeks to address it.

The methods section of a research paper describes the research design, the sample selection, the data collection and analysis procedures, and the statistical methods used to analyze the data. This section should provide sufficient detail for other researchers to replicate the study.

The results section presents the findings of the research, using tables, graphs, and figures to illustrate the data. The findings should be presented in a clear and concise manner, with reference to the research question and hypothesis.

The discussion section of a research paper interprets the findings and discusses their implications for the research question, the literature review, and the field of study. It should also address the limitations of the study and suggest future research directions.

The conclusion section summarizes the main findings of the study, restates the research question and hypothesis, and provides a final reflection on the significance of the research.

The references section provides a list of all the sources cited in the paper, following a specific citation style such as APA, MLA or Chicago.

How to Write Research Paper

You can write Research Paper by the following guide:

• Choose a Topic: The first step is to select a topic that interests you and is relevant to your field of study. Brainstorm ideas and narrow down to a research question that is specific and researchable.
• Conduct a Literature Review: The literature review helps you identify the gap in the existing research and provides a basis for your research question. It also helps you to develop a theoretical framework and research hypothesis.
• Develop a Thesis Statement : The thesis statement is the main argument of your research paper. It should be clear, concise and specific to your research question.
• Plan your Research: Develop a research plan that outlines the methods, data sources, and data analysis procedures. This will help you to collect and analyze data effectively.
• Collect and Analyze Data: Collect data using various methods such as surveys, interviews, observations, or experiments. Analyze data using statistical tools or other qualitative methods.

Title: The Impact of Social Media on Mental Health among Young Adults

Abstract: This study aims to investigate the impact of social media use on the mental health of young adults. A literature review was conducted to examine the existing research on the topic. A survey was then administered to 200 university students to collect data on their social media use, mental health status, and perceived impact of social media on their mental health. The results showed that social media use is positively associated with depression, anxiety, and stress. The study also found that social comparison, cyberbullying, and FOMO (Fear of Missing Out) are significant predictors of mental health problems among young adults.

Introduction: Social media has become an integral part of modern life, particularly among young adults. While social media has many benefits, including increased communication and social connectivity, it has also been associated with negative outcomes, such as addiction, cyberbullying, and mental health problems. This study aims to investigate the impact of social media use on the mental health of young adults.

Literature Review: The literature review highlights the existing research on the impact of social media use on mental health. The review shows that social media use is associated with depression, anxiety, stress, and other mental health problems. The review also identifies the factors that contribute to the negative impact of social media, including social comparison, cyberbullying, and FOMO.

Methods : A survey was administered to 200 university students to collect data on their social media use, mental health status, and perceived impact of social media on their mental health. The survey included questions on social media use, mental health status (measured using the DASS-21), and perceived impact of social media on their mental health. Data were analyzed using descriptive statistics and regression analysis.

Results : The results showed that social media use is positively associated with depression, anxiety, and stress. The study also found that social comparison, cyberbullying, and FOMO are significant predictors of mental health problems among young adults.

Discussion : The study’s findings suggest that social media use has a negative impact on the mental health of young adults. The study highlights the need for interventions that address the factors contributing to the negative impact of social media, such as social comparison, cyberbullying, and FOMO.

Conclusion : In conclusion, social media use has a significant impact on the mental health of young adults. The study’s findings underscore the need for interventions that promote healthy social media use and address the negative outcomes associated with social media use. Future research can explore the effectiveness of interventions aimed at reducing the negative impact of social media on mental health. Additionally, longitudinal studies can investigate the long-term effects of social media use on mental health.

Limitations : The study has some limitations, including the use of self-report measures and a cross-sectional design. The use of self-report measures may result in biased responses, and a cross-sectional design limits the ability to establish causality.

Implications: The study’s findings have implications for mental health professionals, educators, and policymakers. Mental health professionals can use the findings to develop interventions that address the negative impact of social media use on mental health. Educators can incorporate social media literacy into their curriculum to promote healthy social media use among young adults. Policymakers can use the findings to develop policies that protect young adults from the negative outcomes associated with social media use.

How to Write a Lab Report – with Example/Template

April 11, 2024

Perhaps you’re in the midst of your challenging AP chemistry class in high school, or perhaps college you’re enrolled in biology , chemistry , or physics at university. At some point, you will likely be asked to write a lab report. Sometimes, your teacher or professor will give you specific instructions for how to format and write your lab report, and if so, use that. In case you’re left to your own devices, here are some guidelines you might find useful. Continue reading for the main elements of a lab report, followed by a detailed description of the more writing-heavy parts (with a lab report example/lab report template). Lastly, we’ve included an outline that can help get you started.

What is a lab report?

A lab report is an overview of your experiment. Essentially, it explains what you did in the experiment and how it went. Most lab reports end up being 5-10 pages long (graphs or other images included), though the length depends on the experiment. Here are some brief explanations of the essential parts of a lab report:

Title : The title says, in the most straightforward way possible, what you did in the experiment. Often, the title looks something like, “Effects of ____ on _____.” Sometimes, a lab report also requires a title page, which includes your name (and the names of any lab partners), your instructor’s name, and the date of the experiment.

Abstract : This is a short description of key findings of the experiment so that a potential reader could get an idea of the experiment before even beginning.

Introduction : This is comprised of one or several paragraphs summarizing the purpose of the lab. The introduction usually includes the hypothesis, as well as some background information.

Lab Report Example (Continued)

Materials : Perhaps the simplest part of your lab report, this is where you list everything needed for the completion of your experiment.

Methods : This is where you describe your experimental procedure. The section provides necessary information for someone who would want to replicate your study. In paragraph form, write out your methods in chronological order, though avoid excessive detail.

Data : Here, you should document what happened in the experiment, step-by-step. This section often includes graphs and tables with data, as well as descriptions of patterns and trends. You do not need to interpret all of the data in this section, but you can describe trends or patterns, and state which findings are interesting and/or significant.

Discussion of results : This is the overview of your findings from the experiment, with an explanation of how they pertain to your hypothesis, as well as any anomalies or errors.

Conclusion : Your conclusion will sum up the results of your experiment, as well as their significance. Sometimes, conclusions also suggest future studies.

Sources : Often in APA style , you should list all texts that helped you with your experiment. Make sure to include course readings, outside sources, and other experiments that you may have used to design your own.

How to write the abstract

The abstract is the experiment stated “in a nutshell”: the procedure, results, and a few key words. The purpose of the academic abstract is to help a potential reader get an idea of the experiment so they can decide whether to read the full paper. So, make sure your abstract is as clear and direct as possible, and under 200 words (though word count varies).

When writing an abstract for a scientific lab report, we recommend covering the following points:

• Background : Why was this experiment conducted?
• Objectives : What problem is being addressed by this experiment?
• Methods : How was the study designed and conducted?
• Results : What results were found and what do they mean?
• Conclusion : Were the results expected? Is this problem better understood now than before? If so, how?

How to write the introduction

The introduction is another summary, of sorts, so it could be easy to confuse the introduction with the abstract. While the abstract tends to be around 200 words summarizing the entire study, the introduction can be longer if necessary, covering background information on the study, what you aim to accomplish, and your hypothesis. Unlike the abstract (or the conclusion), the introduction does not need to state the results of the experiment.

Here is a possible order with which you can organize your lab report introduction:

• Intro of the intro : Plainly state what your study is doing.
• Background : Provide a brief overview of the topic being studied. This could include key terms and definitions. This should not be an extensive literature review, but rather, a window into the most relevant topics a reader would need to understand in order to understand your research.
• Importance : Now, what are the gaps in existing research? Given the background you just provided, what questions do you still have that led you to conduct this experiment? Are you clarifying conflicting results? Are you undertaking a new area of research altogether?
• Prediction: The plants placed by the window will grow faster than plants placed in the dark corner.
• Hypothesis: Basil plants placed in direct sunlight for 2 hours per day grow at a higher rate than basil plants placed in direct sunlight for 30 minutes per day.
• How you test your hypothesis : This is an opportunity to briefly state how you go about your experiment, but this is not the time to get into specific details about your methods (save this for your results section). Keep this part down to one sentence, and voila! You have your introduction.

How to write a discussion section

Here, we’re skipping ahead to the next writing-heavy section, which will directly follow the numeric data of your experiment. The discussion includes any calculations and interpretations based on this data. In other words, it says, “Now that we have the data, why should we care?”  This section asks, how does this data sit in relation to the hypothesis? Does it prove your hypothesis or disprove it? The discussion is also a good place to mention any mistakes that were made during the experiment, and ways you would improve the experiment if you were to repeat it. Like the other written sections, it should be as concise as possible.

Here is a list of points to cover in your lab report discussion:

• Weaker statement: These findings prove that basil plants grow more quickly in the sunlight.
• Stronger statement: These findings support the hypothesis that basil plants placed in direct sunlight grow at a higher rate than basil plants given less direct sunlight.
• Factors influencing results : This is also an opportunity to mention any anomalies, errors, or inconsistencies in your data. Perhaps when you tested the first round of basil plants, the days were sunnier than the others. Perhaps one of the basil pots broke mid-experiment so it needed to be replanted, which affected your results. If you were to repeat the study, how would you change it so that the results were more consistent?
• Implications : How do your results contribute to existing research? Here, refer back to the gaps in research that you mentioned in your introduction. Do these results fill these gaps as you hoped?
• Questions for future research : Based on this, how might your results contribute to future research? What are the next steps, or the next experiments on this topic? Make sure this does not become too broad—keep it to the scope of this project.

How to write a lab report conclusion

This is your opportunity to briefly remind the reader of your findings and finish strong. Your conclusion should be especially concise (avoid going into detail on findings or introducing new information).

Here are elements to include as you write your conclusion, in about 1-2 sentences each:

• Restate your goals : What was the main question of your experiment? Refer back to your introduction—similar language is okay.
• Restate your methods : In a sentence or so, how did you go about your experiment?
• Key findings : Briefly summarize your main results, but avoid going into detail.
• Limitations : What about your experiment was less-than-ideal, and how could you improve upon the experiment in future studies?
• Significance and future research : Why is your research important? What are the logical next-steps for studying this topic?

Template for beginning your lab report

Here is a compiled outline from the bullet points in these sections above, with some examples based on the (overly-simplistic) basil growth experiment. Hopefully this will be useful as you begin your lab report.

Ethics of Care and Employees: The Impact of Female Board Representation and Top Management Leadership on Human Capital Development Policies

• Original Paper

While scholarly research on the relationship between female board representation and strategic decision-making has gained momentum, employee policy outcomes have remained relatively understudied. Integrating theory from the ethics of care perspective with research on the glass ceiling and workplace voice, we seek to understand the circumstances under which female directors influence policy changes for firm employees. We argue that firms with increasing female board representation are more likely to enact human capital development policies benefiting firm employees. However, this positive relationship will ultimately diminish as boards accrue an increasing number of female directors. We further predict that the presence of a female leader at the firm (serving in the role of either the CEO or the board chair) will moderate this diminishing effect. Using a sample of S&P 1500 firms, we find support for our hypotheses. The findings from this study provide evidence that while female board representation is positively related to human capital development policies, this effect is nuanced and impacted by the presence of female leadership at the top of organizations. Our paper extends existing research on the nature of female directors’ influence on ethical decisions, emphasizing the impact of these directors on employees.

Avoid common mistakes on your manuscript.

Introduction

“You observe things from a special vantage point when you live in a world and work in an industry that was built to hold you back.” —Lan Nguyen Chaplin, Harvard Business Review.

While the number of female directors remains low (Hoobler et al., 2009 ; Mitra et al., 2021 ), female board representation (FBR) has increased substantially in recent years as firms face pressure to include more women on their boards (Chang et al., 2018 ; Fernandez-Mateo & Kaplan, 2018 ). Given this push, understanding how female representation on boards impacts firms has become a question of interest for management scholars (Jeong & Harrison, 2017 ; Post & Byron, 2015 ; Roberson et al., 2017 ). Scholars have been increasingly devoting attention to the impact of female directors on key firm outcomes (e.g., Chen et al., 2016a ; Hoobler et al., 2018 ). However, the attention has primarily been limited to outcomes focusing on financial performance (Campbell and Minguez-Vera 2008 ; Chapple & Humphrey, 2014 ), corporate social responsibility (Byron & Post, 2016 ; Cook & Glass, 2018 ), innovation and risk-taking (Chen et al., 2016b ; Post et al., 2022 ), and customer perceptions (Wowak et al., 2020 ) with scarce attention to how FBR can impact firm employees (Glass & Cook, 2018 ).

Our study seeks to explore the circumstances under which FBR shapes employee-specific policies implemented at firms. We build our theoretical arguments using prior research on the ethics of care, which theorizes about gender-based differences in the ethical behaviors between men and women (Gilligan, 1982 ; Islam, 2013 ). This perspective suggests that women are relatively more committed to empathetic caring for others (e.g., Boulouta, 2013 ; Stajkovic & Stajkovic, 2023 ) in part because they recognize the care stakeholders need and their responsibility to fulfill it (Au & Stephens, 2023 ; Branicki, 2020 ). In our paper, we argue that female directors play a crucial role in attending to employees at their firm.

We contend that FBR impacts the enactment of human capital development (HCD) policies—policies that develop employees’ knowledge, skills, and abilities enhancing their workplace productivity (Crook et al., 2011 ; Jiang et al., 2012 ; Kim & Ployhart, 2014 ). Women all too often experience an acute shortage of HCD and related barriers as they advance through the workplace and break the ‘glass ceiling’ (Cook & Glass, 2014 ; Hoobler et al., 2009 , 2014 ). As such, women are well aware of the challenges that many employees face to equitably advance their career trajectories (Cohen et al., 2020 ; Lewellyn & Muller-Kahle, 2020 ; Mun & Jung, 2018 ). Drawing from the ethics of care literature, we theorize as to why barriers, such as the glass ceiling (Elley-Brown and Pringle, 2021 ), can evoke caring behaviors in female directors. Given the challenges that so many employees face in developing human capital, we argue that these obstacles will shape the experiences, and thus the strategic priorities, of female directors as they engage in providing care to employees of their firm.

While boards with greater female representation may address the challenges to HCD that confront employees, we do not, however, expect these experiences to translate into firm actions equally across the entire range of FBR. Specifically, while we expect this relationship to be positive, we also expect HCD policies to be enacted at a diminishing rate. Our study integrates research from the employee voice literature to argue that the extent of FBR dictates when female directors are likely to voice their experiences with such challenges to prompt policy changes. Workplace voice is conceptualized as a discretionary form of change-oriented communication offered with the intent of improving organizational functioning (Morrison, 2011 ; Van Dyne & LePine, 1998 ). Voicing experiences with workplace issues, such as gender-based challenges to HCD, is an important avenue for prompting organizational changes (Kim et al., 2022 ; Liang et al., 2012 ; Sherf et al., 2019 ). We expect that female directors are likely to advocate for removing the obstacles that employees experience in attempts to develop their human capital; however, when firms attain high levels of FBR, the overlap in gender-based experiences will begin to alter the priorities voiced by female directors. This occurs due to an eventual redundancy in shared perspectives, such that the extent to which female directors voice experiences with barriers to HCD eventually diminishes.

We also consider how the presence of a female leader (female CEO or female board chair) may moderate this relationship. Given that female leadership and FBR can lead to an overlap in experiences, increasing levels of FBR should be less pronounced at firms led by a female CEO and/or a female board chair. As such, we predict that the influence of FBR is impactful over a larger spectrum of FBR at firms without a female leader. Our analyses of a sample of S&P 1500 companies from 2007 to 2017 provide support for our theorized predictions.

Our study makes three contributions. First, we unpack a novel connection between FBR and HCD policies directed toward employees, a key stakeholder group that is often overlooked in studying the influence of FBR. While extensive research has focused on the role female directors play in influencing firm outcomes (Abdullah et al., 2016 ; Isidro & Sobral, 2015 ), little attention has been given to the role of barriers—such as career obstacles linked to the glass ceiling—that shape female directors’ experiences and thereby their motivation to challenge barriers for other employees. We theorize and find support that female directors are more likely to advocate for HCD policies in their organization. Second, we contribute to research on the ethics of care perspective (Alacovska & Bissonnette, 2021 ; Branicki, 2020 ; Elley-Brown & Pringle, 2021 ) by extending our understanding of how female directors care for stakeholders. We develop a new perspective as to why women’s glass ceiling experiences shape female directors’ motivation to engage in care for stakeholders (employees in this case). Our findings indicate that female directors’ care can benefit all employees of the firm through policies that remove barriers to HCD. Finally, drawing on arguments from the employee voice literature (Kim et al., 2022 ; Sherf et al., 2019 ), we add insights to our understanding of the circumstances under which FBR influences firm outcomes. Recent research has begun to call for a more nuanced outlook to understanding how gender-based decision-making behaviors unfold in the workplace (Gamache et al. in press). The support we find for our arguments that female directors may be more reluctant to voice their experiences if there is redundancy in shared perspectives adds to this important stream of research.

Theory and Hypotheses

Ethics of care and female board representation.

The ethics of care approach has its foundation in attentiveness to the needs of others and a responsibility of repairing, creating, and sustaining a better world (Alacovska & Bissonnette, 2021 ; Fisher & Tronto, 1990 ; Tronto, 1993 ). Ethics of care entails a relational focus and values the necessity of interpersonal connectedness (Held, 2006 ; Hoover & Pepper, 2015 ; Nicholson & Kurucz, 2019 ). This perspective emphasizes that an individual or organization should provide care when needed to improve the circumstances of another individual (D’Souza & Martí, 2022 ; Paillé et al., 2016 ; Rynes et al., 2012 ). While building on a philosophy of openness and responsibility to others, this stream of research has increasingly adopted the approach that such concern is not simply a virtuous disposition but rather a type of value that is pursued to enhance wider well-being (Au & Stephens, 2023 ; Branicki, 2020 ; Tomkins & Simpson, 2015 ).

Theory from this ethical perspective has long suggested that, relative to men, women are more inclined to be focused on the development and growth of others (Gilligan, 1982 ; Islam, 2013 ). Women’s unique perspective likewise shapes their views towards caring behaviors in the workplace (Elley-Brown & Pringle, 2021 ). In this way, women’s leadership has been linked to ethical behaviors based on relationality and caring (Pullen and Vachhani, 2021 ). Scholars have built on this logic to demonstrate that women often have an empathy-based caring motivation for others which makes them prioritize a caring attitude toward stakeholders (e.g., Boulouta, 2013 ; Campopiano et al., 2023 ; Jammaers, 2023 ). For example, Stajkovic and Stajkovic ( 2023 ) find that because female mayors exhibit an ethics of care leadership approach, cities run by women are associated with greater levels of urban revitalization, which benefits many stakeholders in these urban regions.

In the context of corporate governance, researchers have also demonstrated that female directors bring distinct perspectives to boards (Adams and Funk, 2011 ) and, in turn, alter group decision-making processes (e.g., Chen et al., 2016a ; Wiersema & Bantel, 1992 ). This occurs because gender-based distinctions in cognitive schemas lead to differences in information seeking, information processing, and subsequent strategy formulation (Post & Byron, 2015 ). While prior research has established that gender plays an important role in board decision-making and important strategic outcomes (Cook & Glass, 2016 , 2018 ; Eagly et al., 1994 ; Eagly and Johnson 1990 ; Gardiner & Tiggemann, 1999 ), we have much to learn about how female directors impact employee stakeholders (Chebbi et al., 2020 ; Glass & Cook, 2018 ).

Although firms have a moral duty to take care of stakeholders (Kaptein, 2022 ), organizations are often unresponsive to the needs of their employees, making them feel neglected and uncared for (Kong & Belkin, 2022 ). Taken together, we believe that ethics of care is an important lens to better understand how firms can identify the unique needs of employees and address them (Lähdesmäki et al., 2019 ). We next link this theory to the challenges that women in the workplace face in developing human capital and, ultimately, breaking through the glass ceiling.

The Glass Ceiling and Human Capital Development

An important stream of research has considered the many different pathways for women to ascend to the top of organizations (Biswas et al., 2023 ; Monteiro et al., 2022 ; Schoonjans et al., 2023 ). The various career trajectories are critical to shaping the experiences of women (Glass & Cook, 2016 ). Prior research has explored the complex pressures on the career trajectories of women in the workplace including gendered role expectations and adherence to social stereotypes (e.g., Cohen et al., 2020 ; Dwivedi et al., 2018 ; Oakley, 2000 ). While the precise experiences of every individual are unique, there are shared aspects—such as gender identity—relevant to our lived experiences. Such experiences may or may not be work-related or have occurred at the organization where an individual is now employed (Choi et al., 2023 ; Glass & Cook, 2020 ; Xu & Ma, 2022 ) given the fluidity of labor markets. For example, prior experience at one firm can inform an individual’s future decision-making in a role at another firm (McDonald et al., 2008 ). As such, the experiences tied to one’s social group are critical to understanding the strategic priorities of individuals who have ascended to the top of organizations.

Women frequently face challenges and institutional barriers to their advancement into leadership ranks, a phenomenon termed “the glass ceiling” (Bass & Avolio, 1994 ; Davidson & Cooper, 1992 ; Morrison et al., 1987 ). Due to societal stereotypes surrounding women in the workplace (Anand & Mitra, 2022 ; Eagly and Johnson 1990 ; Eagly & Karau, 2002 ), women are often unfairly perceived as being unsuited for leadership roles (Carli & Eagly, 2016 ). While female directors have broken through the glass ceiling (Cook & Glass, 2014 , 2016 ), many employees still face difficulties in upward career mobility as they progress through organizations (Dreher, 2003 ; Ryan et al., 2020 ). Indeed, the ubiquity of such biases can shape the experiences of women in the workplace, even if an individual is not directly negatively impacted by such challenges. Although structural barriers to upward mobility present a formidable challenge to all employees, such barriers may be overcome by creating developmental opportunities that build human capital.

Human capital comprises an employee’s knowledge, skills, and abilities that contribute to the individual’s work efficiency (Becker, 1964 ). HCD policies focus on enhancing employees’ skills and providing opportunities for their personal growth and accomplishments (Jiang et al., 2012 ). Investing in HCD strengthens a firm’s competitive advantage (Crook et al., 2011 ; Kim & Ployhart, 2014 ) because knowledgeable and skillful employees perform their tasks, duties, and responsibilities better (Ng & Feldman, 2010 ). The presence of HCD policies not only improves employees’ performance but also enhances employees’ readiness to hold leadership positions in the future (Aguinis & Kraiger, 2008 ).

Studies on the glass ceiling have demonstrated that institutional barriers to HCD are especially salient for women in the workplace (de Klerk & Verreynne, 2017 ), who often have limited access to resources that enable them to acquire and develop skills in their current role (Hoobler et al., 2014 ; Kalaitzi et al., 2017 ). This may occur due to structural exclusion in the workplace (Greguletz et al., 2019 ; Woehler et al., 2021 ) or disadvantages stemming from inequality woven into organizational norms (Bowles et al., 2019 ). In addition, they may be denied critical feedback (Walton et al., 2015 ) or receive ambiguous feedback (Bear et al., 2017 ). Female employees’ supervisors may not perceive them as suitable successors due to a lack of perceived fit (Rink et al., 2019 ). Women may also experience gender-based discrimination when it comes to performance appraisals (Stamarski & Son Hing, 2015 ), challenging opportunities (King et al., 2012 ), and complex jobs (Joshi et al., 2015 ) out of benevolent sexism (Hideg & Ferris, 2016 ). Taken together, the glass ceiling is a formidable career barrier to many women and, as such, should be salient to female directors when they rise to firm roles that enable them to alter the barriers employees face to HCD.

Consistent with the importance of HCD to firms, there is widespread acknowledgment that these obstacles should be remedied for employees. However, these barriers have persisted in many firms. We next integrate research on employee voice to provide insights into why we predict that increases in FBR will have a positive, but diminishing, effect on the enactment of HCD policies.

The Relationship Between FBR and HCD Policies: Positive at a Diminishing Rate

We theorize that the glass ceiling shapes the experiences of women in the workplace and thus the actions they prioritize advocating for when they reach the boardroom. Female directors shape the board’s decision-making by voicing experiences with barriers to HCD. Due to the broad developmental barriers in the workplace (e.g., Bass & Avolio, 1994 ; Dreher, 2003 ), the need for improved HCD opportunities for employees is especially salient for female directors. In our context, we predict that female directors will be motivated to advocate for a caring behavior that can benefit all employees (and thus, benefit the firm more broadly). This is not to suggest that they will not also advocate for other policies such as those specific to women in the workplace—indeed, prior research has established directors with diverse backgrounds often use their roles for this purpose (e.g., Biswas et al., 2021 ; Skaggs et al., 2012 ). Rather, we expect that by voicing experiences specific to the glass ceiling, FBR will be associated with a shift in focus toward a greater stakeholder orientation in which firms are more likely to discuss the obstacles to HCD faced by all employees. Further, groups who have traditionally faced barriers have an incentive to challenge and change existing institutions for others (Clemens, 1993 ). For female directors, the greater motive is to remove these barriers that restrict the growth and development of firm employees. Removing these barriers fosters a more equitable and fairer workplace for everyone regardless of one’s social identity (Joshi & Diekman, 2022 ).

Theory from the ethics of care perspective suggests that female directors should be not only aware of challenges inherent to the glass ceiling but also motivated to voice such obstacles to enact changes. This approach emphasizes how individuals can engage in care, such as the maintenance and repair of organizational issues for constituents (Ryan et al., 2023 ). Given their experiences with the glass ceiling, female directors are positioned for both recognizing “the need for care (caring about)” and “taking responsibility for care (taking care)” (Branicki, 2020 , p. 879). By advocating for HCD policies female directors can care for employees, with such care providing critical ongoing support to a key stakeholder of the firm (Lawrence & Maitlis, 2012 ). Beyond the potential performance benefits such policies provide for the firm and employees, an ethics of care view argues that those who are aware of issues have a moral responsibility to provide care for another if positioned to do so (Au & Stephens, 2023 ; Held, 2006 ). This logic suggests that the experience of being a woman in the workplace prompts female directors to be both aware of relevant barriers to HCD as well as motivated to voice their experiences with such issues to address them now that they can provide such care for all employees at their firm.

We expect the relationship between FBR and HCD policies to be positive but at a diminishing rate. At high levels of FBR, the saliency of glass ceiling barriers is reduced for directors on the board. Drawing from the employee voice literature (Kim et al., 2022 ; Liang et al., 2012 ; Sherf et al., 2019 ), we assert that there is ultimately a point at which the overlap in experiences amongst female directors diminishes the likelihood that they prioritize voicing concerns about HCD issues. Perhaps counter-intuitively, greater awareness of an issue often makes it less likely that the issue is voiced because overlapping information is thought to be shared among individuals (Hussain et al., 2019 ). Often referred to as the ‘bystander effect,’ studies have shown that the greater the information redundancy in a group, the less any individual in the group feels individually responsible for voicing such information (e.g., Darley & Latane, 1968 ; Fischer et al., 2011 ; Oc & Kouchaki, 2023 ). Group decision-making research similarly theorizes that extended discussions that lead to information integration are most common for groups with access to distinct, rather than overlapping, information (e.g., Homan et al., 2007 ). This is not to imply that female directors begin to view such issues as unimportant—rather, the information redundancy associated with increasingly shared experiences shifts the priorities they voice during strategic decision-making.

In our context, this logic suggests that the extent to which female directors emphasize developmental challenges inherent to breaking through the glass ceiling is at least partially dependent upon the distinctiveness of their perspective. As information redundancy in gender-based experiences rises, the saliency of issues inherent to the glass ceiling gradually dissipates for boards with high levels of FBR. In sum, we theorize that the divergent perspectives brought to the fore by FBR initially will lead to increases in HCD policies but this positive effect ultimately diminishes as FBR continues to increase. As such, we expect that greater representation of female directors on the board may not necessarily translate directly into corresponding additional changes associated with their distinct perspectives. This leads us to our first hypothesis.

Hypothesis 1

The relationship between female board representation and the enactment of human capital development policies is positive at a diminishing rate.

The Interactive Effect of Female Leaders in the Firm

Firm leaders are critical to shaping the impact of directors serving on the board (Guldiken et al., 2019 ; Vandewaerde et al., 2011 ) and caring for firm employees (Monteiro et al., 2022 ). We focus on CEOs and board chairs as firm leaders because these roles have oversight over the strategic decisions made by firms and boards, including the allocation of resources and the adoption of workplace policies (Banerjee et al., 2020 ; Walls & Berrone, 2017 ). Research on workplace voice focuses on communication that is directed ‘upward’ in hierarchical organizational structures and, thus, leadership is key to determining whether employee voice ultimately prompts organizational changes (Kim et al., 2022 ; Morrison, 2023 ).

We predict that firm leadership influences the issues that female directors prioritize voicing. Specifically, we expect that the presence of female leadership at the firm will moderate the relationship between FBR and HCD policies. While female directors are often considered to be more influential in strategic decision-making when there is female leadership at the firm (Glass & Cook, 2018 ), this also creates an overlap in gender-based experiences. The workplace voice literature theorizes that such an overlap presents a redundancy in information. As noted earlier, redundancies in experience have previously been linked to changes in the strategic priorities voiced by individuals (Hussain et al., 2019 ).

We build off this logic to argue that female directors may defer to female leaders to voice gender-based experiences. This is because female leaders have also encountered experiences with the glass ceiling, and therefore have overlap in gender-based experiences with female directors. Female directors at these firms may feel less personally accountable to voice their gender-based experiences to provide care for other employees, as female leaders both share experiences with the glass ceiling and have relatively greater power to enact policy changes (Banerjee et al., 2020 ; Kakabadse et al., 2015 ). Therefore, we expect the presence of a female leader at the firm to further introduce redundancies in gender-based workplace experiences. In contrast, we expect that increasing levels of FBR will be especially impactful at firms led by a male leader (i.e., in the role of CEO or board chair). Boardroom discussions and deliberations at these firms would otherwise presumably result in little insights into barriers to HCD without the presence of female directors. This leads us to our second hypothesis.

Hypothesis 2

The positive relationship between female board representation and the enactment of human capital development policies will diminish at a faster rate for firms with a female as the CEO or the board chair.

Data and Sample

Our study covers S&P 1500 companies from 2007 to 2017. Firm-level data were collected from Compustat, Institutional Shareholder Services (ISS), and Refinitiv. Compustat is a financial data provider; it offers a variety of public accounting information, such as total firm assets and research expenditures. ISS provides corporate governance data. Refinitiv (formally part of Thomson Reuters) provides labor policies data. After merging the data from these sources and eliminating observations with missing data, our sample consisted of 6936 firm-year observations embedded in 1148 unique firms. For our final data analysis, female directors and all control variables are measured at time t, and HCD policies are measured at time t  + 1, resulting in a final sample of 5648 firm-year observations embedded in 1,098 unique firms when the lag structure is incorporated.

Main Variables

Human capital development policies.

This variable was derived from the Refinitiv ESG database, which is an enhancement and replacement of the well-known Thomson Reuters ASSET4 database. Refinitiv ESG provides not only variables capturing the overall corporate social performance (CSP) of an organization, but also policies that capture different forms of CSP such as labor rights policies and practices (Rathert, 2016 ). Consistent with previous research that examined subcomponents of CSR rating services (Cook & Glass, 2015 ), we used four HCD policies in our study: “Policy Skills Training” (Does the company have a policy to improve the skills training of its employees?), “Policy Career Development” (Does the company have a policy to improve the career development paths of its employees?), “Management Training” (Does the company claim to provide regular staff and business management training for its managers?), and “Training and Development Policy” (Does the company have a policy to support the skills training or career development of its employees?). Each of these variables was assigned the value 1 if the company claimed to offer such a policy, and 0 if no such claims were made. The Human capital development policies variable was then calculated as the mean of these four HCD policies, resulting in a variable that ranges from zero to one with several values in between.

Female Board Representation

We derived this variable from the ISS Directors database. The gender of each director is classified by ISS via a dummy variable, taking the value 1 if a director serving on the board is female and 0 if the director is male. We counted the total number of female directors on the board in a given firm-year. This variable does not include female board leaders (i.e., female board chair) as well as female corporate leaders (e.g., female CEO). These variables are captured in the following variable.

Female Leader

We derived the data for this construct from ISS Directors. It is a binary variable that takes the value 1 if the company has a female leader of the board (i.e., female board chair) or a female corporate leader (i.e., female CEO) and 0 otherwise.

Control Variables

We controlled for several variables at the firm level. First, firm size was measured by total assets. This variable was included to account for the effects of firm size on HCD policies, as larger firms may see greater benefits and returns from HCD. R&D intensity, operationalized as R&D expenditures divided by firm revenues, is controlled for because firms with a greater focus on R&D may benefit more from HCD policies. Third, leverage was measured as long-term debt and debt in current liabilities divided by total assets. Firms with greater financial leverage may find it more challenging to invest resources in long-term projects such as improving the human capital of current employees. Fourth, we included ROA to account for the effects of firm performance on HCD policies, as firms with better financial performance may invest more resources into their employees’ human capital. Lastly, internal promotion captured whether the firm claimed to favor promotion from within rather than hiring from the outside. This variable is a potentially important antecedent of HCD policies because a company with a greater focus on internal promotion may be more likely to invest in HCD policies.

We also included control variables relevant to the corporate governance of each firm. First, board size was measured as the total number of directors on the board. Larger boards may be ineffective monitors of top management due to collective action and coordination problems. Next, board independence was measured as the percentage of directors on the board who are outsiders. More independent boards can introduce new perspectives on management and labor practices, in addition to better monitoring of the executive team. Third, CEO duality was a dummy variable, taking the value 1 if the CEO is also the chairperson of the board and 0 otherwise. We also control for board ownership measured as the percentage of firm shares owned by all directors. Higher levels of firm ownership may motivate directors to examine and implement innovative labor-management policies. Lastly, we controlled for ownership concentration , defined as the proportion of shares held by the five largest shareholders in the firm. A higher value for this variable indicates a more concentrated shareholder structure, which in turn may indicate more vigilant monitoring of the firm’s operations by investors.

Analytical Strategy

Because our sample reflects panel data, we incorporated firm fixed effects to control for unobserved heterogeneity across firms, thereby capturing the unique, time-invariant characteristics of each firm that could influence the dependent variable. While random effects are generally more efficient than fixed effects models, they assume that unobserved effects are uncorrelated with the explanatory variables. If this assumption is violated, random effects models may produce biased results and fixed effects panel models should be used to reduce potential bias (at the expense of efficiency). Therefore, we conducted a Hausman test to examine the consistency of the fixed effects estimator in comparison to the random effects model. The results of this test (χ 2  = 30.88, p  < 0.001) indicate a preference for fixed effects estimators. Hence, we include fixed effects for firms and fixed effects for years in our models. Further, to estimate a more appropriate causal order, we measured the independent variable and all controls at time t and HCD policies at t  + 1.

The presence of female directors on the board is a strategic corporate governance decision that may raise endogeneity concerns because certain firms may self-select into the treatment condition (i.e., increasing female board representation ) with the goal of improving the working conditions of employees (i.e., actions that improve human capital development policies ). It is challenging to model these selection factors and hence self-selection-based endogeneity may bias our results (Clougherty et al., 2016 ). To address this concern, we utilized the Heckman correction approach (Heckman, 1979 ). The selection model predicts the presence of at least one female director on the board in a particular firm-year while including all control variables as well as an additional instrumental variable. The instrument used is the average female director ratio in a particular industry. The industry mean of the ultimate independent variable is emerging as an important instrument (Krause et al., 2019 , p. 297), because intra-industry pressures for conforming to industry norms will lead firms in the same industry to imitate and mirror important governance decisions made by their peers. From the selection model, we estimated an endogeneity correction factor (the inverse Mills ratio [ IMR ]) that we included as an additional variable in our models.

Table  1 reports our descriptive statistics and correlations. The variables used in this study were not generally highly correlated. Besides the correlation between FBR and FBR squared (which was expected and appropriate), human capital development policies and internal promotion were correlated at r  = 0.41. This effect is informative and illustrates that firms with internal promotion policies are also likely to implement more HCD policies.

Table  2 reports the results of the first-stage procedure. Model 1 in this table includes control variables only. Consistent with our expectations and previous research, larger firms and firms with larger and more independent boards were more likely to have at least one female director present on the board. Model 2 includes all control variables as well as the instrumental variable female director ratio (industry) . As expected, this instrument had a positive and statistically significant ( p  < 0.001) effect on the presence of a female director on the board.

Table  3 reports the results of our main analysis with human capital development policies as the outcome variable . Model 1 reports the results of the control variable model. The effects reported are generally in line with our expectations and provide interesting insights. For instance, firms with Internal promotion efforts seem to consistently invest more in HCD policies. Model 2 adds the linear term female board representation to the control variable model. The coefficient has a positive sign and is statistically significant ( p  < 0.001), supporting a simple linear relationship between FBR and HCD policies. Yet, this effect may not fully incorporate potential non-linearities. Model 3 tests Hypothesis 1, which states that the effect of FBR on the enactment of HCD policies is positive with diminishing returns. We tested this hypothesis by including the variable female board representation as well as the square term of female board representation . The positive coefficients on the linear term ( p  < 0.01) and the negative coefficients on the quadratic term ( p  < 0.05) suggested a non-monotonic relationship between FBR and HCD policies, as predicted in Hypothesis 1. In addition, while both Models 2 and 3 may be valid, the incremental model improvement from Model 2 (i.e., the model including only the linear term “female board representation”) to Model 3 (i.e., the model also including the “female board representation squared” term) show significant model improvement ( χ 2 (1) = 4.80, p  < 0.0285), leading us to rely on the non-linear model presented in Model 3.

Figure  1 represents our results graphically, displaying them up to two standard deviations above the mean. A negative quadratic term that is statistically significant suggests that the curve is concave and a curvilinear effect is present if the inflection point of the curve lies within two standard deviations of the mean (Haans et al., 2016 ; Meyer, 2009 ; Wang et al., 2014 ). The inflection point at which the positive relationship between greater FBR and HCD policies begins to diminish is when at least 3 directors on the board are female. Overall, these results are consistent with a diminishing positive relationship between FBR and HCD policies, providing support for Hypothesis 1.

Diminishing returns graph. Notes : Data displayed from zero female board representation to 2 SD above the mean for female board representation

Hypothesis 2 was tested in Model 4. Hypothesis 2 states that the effect of FBR on the enactment of HCD policies diminishes at a faster rate for firms with a female as the CEO or the board chair. Table 3 , Model 4 includes the linear and quadratic-by-

linear interaction terms between FBR and female leader. The linear interaction term is negative and significant ( p  < 0.01) while the quadratic-by-linear interaction term is positive and significant ( p  < 0.05). These findings provide evidence for a diminishing effect of female leader on the relationship between FBR and HCD policies, which provides support for Hypothesis 2.

We also present the visual results of this test in Fig.  2 . This Figure shows that the curve is diminished when a female leader is present. In fact, the curve is suggesting a negative effect of a female leader on HCD policies when FBR is increasing, up to about three female directors on the board. Yet, when a female leader is not present, the curve resembles a positive diminishing effect. We next elaborate on the implications of these findings.

Moderation effect. Notes : Data displayed from zero female board representation to 2 SD above the mean for female board representation

We also examined the significance of model improvements as well as the practical relevance of our findings. First, we compared the within-firm R 2 values between the control variable model and the model including both the linear term female board representation as well as the female board representation squared term. The control variable model has a within-firm R 2 of 0.091 while the main effect model has an R 2 of 0.095. In percentage terms, the increase in within-firm R 2 is around 4%. Second, in terms of the practical significance of the influence of FBR, adding a female director to the board will increase the absolute value of the dependent variable by 0.018. since the DV is scaled from 0 to 1 and has a mean of 0.562. Despite our use of firm fixed effects models—which control for time-invariant firm-level unobservable influences—we find that adding a female director to the board will increase the mean value from 0.562 to 0.580, which is a 3.2% increase in workplace practices. Given that firms spend considerable financial resources every year on HCD policies and the importance of these investments to firm success (Fulmer & Ployhart, 2014 ; Madgavkar et al., 2023 ), a 3.2% increase in these investments is noteworthy. In addition, if we discuss the practical significance from a between-firm perspective and compare firms with 0 female directors (1 SD below the sample mean) to firms with three female directors (1 SD above the sample mean), the percentage increase would be about 10% in relative terms.

Discussion and Conclusion

Attaining a better understanding of how female representation at the top of organizations impacts firm outcomes is a topic of increasing importance. Despite an increasing call for greater FBR, ambiguity persists in the circumstances under which female leaders influence key policy outcomes for firms. Building on theory from the ethics of care perspective, we find support for our contention that an increase in FBR leads to an increase in HCD policies, but that this positive association diminishes as boards amass higher levels of FBR. We also find support for an interactive effect between having a female leader atop the organization and FBR. These findings have important implications for understanding how FBR is associated with ethical decision-making by firms, especially as these decisions impact employees. Furthermore, our work suggests that the benefits of increased gender diversity may be more nuanced than previously thought. We next outline our intended contributions and how future research can build on this study to further discussions into how firms can better engage in caring for employees and other key stakeholders.

Contributions, Limitations, and Implications for Future Research

Our work makes three primary contributions. First, our study contributes to the research on FBR by highlighting the importance of women’s experiences in the workplace (Au & Stephens, 2023 ; Elley-Brown & Pringle, 2021 ) and theorizing about the circumstances under which such experiences influence employees. In this paper, we extend our understanding of the connection between gender-related workplace experiences and the strategic priorities of female directors. Female directors bring in a distinct perspective because of the developmental barriers women confront in the workplace; we find support for our theorizing that this drives their motivation to advocate for policies that break these barriers, demonstrating the importance of FBR in influencing policy changes intended to benefit firm employees. In doing so, we enhance our understanding of how FBR can impact employees–a key stakeholder group, yet one which is often overlooked in arguments surrounding the case for board gender diversity.

Second, our paper further integrates the ethics of care perspective (Gilligan, 1982 ; Jammaers, 2023 ; Stajkovic & Stajkovic, 2023 ) with the literature on FBR (Adams and Ferreira 2009 ; Mitra et al., 2021 ; Post & Byron, 2015 ). There has been a growing stream of research exploring the ethical and moral dimensions of relational leadership that emphasizes the importance of care for the development and well-being of firm stakeholders (Nicholson & Kurucz, 2019 ). Our study suggests that, because of workplace experiences related to the glass ceiling, female directors are more likely than male directors to embody an ethics of care approach towards employees and advocate for increases in HCD policies. These findings contribute to research on ethics of care by enriching our understanding of the different ways that female directors manifest caring behavior in their leadership.

Third, our study also extends research that has begun to call for more investigation of the factors that influence the extent to which female representation in leadership engenders change within organizations (Turban et al., 2019 ; Zhang, 2020 ). By integrating the employee voice literature our study advances research on FBR, revealing that increasing levels of FBR will be especially impactful at firms led by male leaders. In this way, our finding is consistent with the logic of overlapping female voices amongst firm decision-makers. This conclusion runs counter to the notion that issues inherent to the glass ceiling will be ultimately ended once women are either on the board or in leadership positions at firms, in which case an increasing presence of women at the top of firms would perpetually strengthen the impact of HCD policies.

Our study has several limitations that we believe point to opportunities for future research. First, while we focus on HCD policies as a caring outcome because it is closely linked with our theorizing, FBR may be linked to other forms of caring behaviors for firm employees. For example, future research should explore how firms can better leverage increases in FBR to advantages in key outcomes such as employee retention and organizational citizenship behaviors. Second, while our study theorizes about why women-specific experiences with the glass ceiling motivate policies linked to HCD, we acknowledge that we are unable to individually assess the unique experiences of these female directors. As discussed in our study, the paths that individuals take to the top of organizations are often quite varied. Exploring other experiences along the career trajectories that may interact with gender to influence the caring behaviors of female directors, or the temporal aspects of such impactful experiences, represents a promising avenue for future research. For example, future research can explore whether female directors are more likely to prioritize voicing the need for HCD policies (or other employee-specific needs) if they have more firm-specific knowledge due to ascending to their role internally, as opposed to being appointed to the board as an outside director. Relatedly, we assume that women in the workplace will either experience or at least be aware of barriers linked to the glass ceiling. We hope that our study prompts further research to advance our understanding of such experiences and how they shape ethical decision-making by female directors.

The results from this study highlight a diminishing relationship between FBR and HCD policies. We theorize that this occurs because—as information redundancy in gender-based experiences rises—the saliency of obstacles linked to HCD gradually dissipates for boards with high levels of FBR. This may have implications for scholars interested in understanding the relationship between a critical mass of FBR and the impact of female directors on firm outcomes. Extensive research on critical mass points to a minimum threshold of women being needed for female directors to influence decision-making (e.g., Chapple & Humphrey, 2014 ; Seebeck & Vetter, 2021 ; Torchia et al., 2011 ). However, this logic suggests that as FBR keeps increasing, female directors are less likely to be viewed as just representatives of women as a social group (Adriaanse, 2016 ; Konrad et al., 2008 ). Our paper adds to this scholarly conversation by theorizing that even as FBR keeps increasing, it may not always yield positive effects; rather, female directors may be less likely to voice their experiences because of information redundancy in shared experiences with other female directors or leaders. This is not to suggest that FBR ultimately becomes unimportant; rather, the findings from this study indicate a need for scholars to further explore how diverse voices can be successfully integrated into organizational decision-making. We hope that future studies build on our findings to determine how firms can better leverage diversity, such that the benefits of diverse viewpoints do not diminish as the diversity of firm decision-makers continues to increase.

We also acknowledge that the archival data we utilize does not fully capture the complex behaviors of female directors or the interplay of board dynamics when it comes to ethical decision-making (Barnes et al., 2018 ). While we theorize that female directors’ experiences motivate them to advocate for employee-related policies, we do not empirically investigate how female directors shift board agendas or the extent to which they monitor the successful implementation of such policies. We call on future research to explore the role of these dynamics, especially work that utilizes complementary methodological designs such as qualitative or experimental research. Finally, since our sample ends in 2017, we were not able to test if caring behaviors towards employees have changed following the COVID-19 pandemic or important social movements such as the rallies following George Floyd’s death. Companies are increasingly scrutinized about the ways they are (or are not) being inclusive and attending to distinct stakeholder needs (Capo et al., 2024 ; Dong et al., 2023 ). We encourage future research to investigate the potential for changes in ethical decision-making by firms before and after such significant events.

Metrics details

Public health emergencies are characterized by uncertainty, rapid transmission, a large number of cases, a high rate of critical illness, and a high case fatality rate. The intensive care unit (ICU) is the “last line of defense” for saving lives. And ICU resources play a critical role in the treatment of critical illness and combating public health emergencies.

This study estimates the demand for ICU healthcare resources based on an accurate prediction of the surge in the number of critically ill patients in the short term. The aim is to provide hospitals with a basis for scientific decision-making, to improve rescue efficiency, and to avoid excessive costs due to overly large resource reserves.

A demand forecasting method for ICU healthcare resources is proposed based on the number of current confirmed cases. The number of current confirmed cases is estimated using a bilateral long-short-term memory and genetic algorithm support vector regression (BILSTM-GASVR) combined prediction model. Based on this, this paper constructs demand forecasting models for ICU healthcare workers and healthcare material resources to more accurately understand the patterns of changes in the demand for ICU healthcare resources and more precisely meet the treatment needs of critically ill patients.

Data on the number of COVID-19-infected cases in Shanghai between January 20, 2020, and September 24, 2022, is used to perform a numerical example analysis. Compared to individual prediction models (GASVR, LSTM, BILSTM and Informer), the combined prediction model BILSTM-GASVR produced results that are closer to the real values. The demand forecasting results for ICU healthcare resources showed that the first (ICU human resources) and third (medical equipment resources) categories did not require replenishment during the early stages but experienced a lag in replenishment when shortages occurred during the peak period. The second category (drug resources) is consumed rapidly in the early stages and required earlier replenishment, but replenishment is timelier compared to the first and third categories. However, replenishment is needed throughout the course of the epidemic.

The first category of resources (human resources) requires long-term planning and the deployment of emergency expansion measures. The second category of resources (drugs) is suitable for the combination of dynamic physical reserves in healthcare institutions with the production capacity reserves of corporations. The third category of resources (medical equipment) is more dependent on the physical reserves in healthcare institutions, but care must be taken to strike a balance between normalcy and emergencies.

Introduction

The outbreak of severe acute respiratory syndrome (SARS) in 2003 was the first global public health emergency of the 21st century. From SARS to the coronavirus disease (COVID-19) pandemic at the end of 2019, followed shortly by the monkeypox epidemic of 2022, the global community has witnessed eight major public health events within the span of only 20 years [ 1 ]. These events are all characterized by high infection and fatality rates. For example, the number of confirmed COVID-19 cases worldwide is over 700 million, and the number of deaths has exceeded 7 million [ 2 ]. Every major public health emergency typically consists of four stages: incubation, outbreak, peak, and decline. During the outbreak and transmission, surges in the number of infected individuals and the number of critically ill patients led to a corresponding increase in the urgent demand for intensive care unit (ICU) medical resources. ICU healthcare resources provide material security for rescue work during major public health events as they allow critically ill patients to be treated, which decreases the case fatality rate and facilitates the prevention and control of epidemics. Nevertheless, in actual cases of prevention and control, the surge in patients has often led to shortages of ICU healthcare resources and a short-term mismatch of supply and demand, which are problems that have occurred several times in different regions. These issues can drastically impact anti-epidemic frontline healthcare workers and the treatment outcomes of infected patients. According to COVID-19 data from recent years, many infected individuals take about two weeks to progress from mild to severe disease. As the peak of severe cases tends to lag behind that of infected cases, predicting the changes in the number of new infections can serve as a valuable reference for healthcare institutions in forecasting the demand for ICU healthcare resources. The accurate forecasting of the demand for ICU healthcare resources can facilitate the rational resource allocation of hospitals under changes in demand patterns, which is crucial for improving the provision of critical care and rescue efficiency. Therefore, in this study, we combined a support vector regression (SVR) prediction model optimized by a genetic algorithm (GA) with bidirectional long-short-term memory (BILSTM), with the aim of enhancing the dynamic and accurate prediction of the number of current confirmed cases. Based on this, we forecasted the demand for ICU healthcare resources, which in turn may enable more efficient resource deployment during severe epidemic outbreaks and improve the precise supply of ICU healthcare resources.

Research on the demand forecasting of emergency materials generally employs quantitative methods, and traditional approaches mainly include linear regression and GM (1,1). Linear regression involves the use of regression equations to make predictions based on data. Sui et al. proposed a method based on multiple regression that aimed to predict the demand for emergency supplies in the power grid system following natural disasters [ 3 ]. Historical data was used to obtain the impact coefficient of each factor on emergency resource forecasting, enabling the quick calculation of the demand for each emergency resource during a given type of disaster. However, to ensure prediction accuracy, regression analysis needs to be supported by data from a large sample size. Other researchers have carried out demand forecasting for emergency supplies from the perspective of grey prediction models. Li et al. calculated the development coefficient and grey action of the grey GM (1,1) model using the particle swarm optimization algorithm to minimize the relative errors between the real and predicted values [ 4 ]. Although these studies have improved the prediction accuracy of grey models, they mainly involve pre-processing the initial data series without considering the issue of the excessively fast increase in predicted values by traditional grey GM (1,1) models. In emergency situations, the excessively fast increase in predicted values compared to real values will result in the consumption of a large number of unnecessary resources, thereby decreasing efficiency and increasing costs. As traditional demand forecasting models for emergency supplies have relatively poor perfect order rates in demand analysis, which result in low prediction accuracy, they are not mainstream.

At present, dynamic models of infectious diseases and demand forecasting models based on machine learning are at the cutting edge of research. With regard to the dynamic models of infectious diseases, susceptible infected recovered model (SIR) is a classic mathematical model employed by researchers [ 5 , 6 , 7 ]. After many years of development, the SIR model has been expanded into various forms within the field of disease transmission, including susceptible exposed infected recovered model (SEIR) and susceptible exposed infected recovered dead model (SEIRD) [ 8 , 9 ]. Nevertheless, with the outbreak of COVID-19, dynamic models of infectious diseases have once again come under the spotlight, with researchers combining individual and group variables and accounting for different factors to improve the initial models and reflect the state of COVID-19 [ 10 , 11 , 12 , 13 ]. Based on the first round of epidemic data from Wuhan, Li et al. predicted the time-delay distributions, epidemic doubling time, and basic reproductive number [ 14 ]. Upon discovering the presence of asymptomatic COVID-19 infections, researchers began constructing different SEIR models that considered the infectivity of various viral incubation periods, yielding their respective predictions of the inflection point. Based on this, Anggriani et al. further considered the impact of the status of infected individuals and established a transmission model with seven compartments [ 15 ]. Efimov et al. set the model parameters for separating the recovered and the dead as uncertain and applied the improved SEIR model to analyze the transmission trend of the pandemic [ 16 ]. In addition to analyzing the transmission characteristics of normal COVID-19 infection to predict the status of the epidemic, many researchers have also used infectious disease models to evaluate the effects of various epidemic preventive measures. Lin et al. applied an SEIR model that considered individual behavioral responses, government restrictions on public gatherings, pet-related transmission, and short-term population movements [ 17 ]. Cao et al. considered the containment effect of isolation measures on the pandemic and solved the model using Euler’s numerical method [ 18 ]. Reiner et al. employed an improved SEIR model to study the impact of non-pharmaceutical interventions implemented by the government (e.g., restricting population movement, enhancing disease testing, and increasing mask use) on disease transmission and evaluated the effectiveness of social distancing and the closure of public spaces [ 19 ]. These studies have mainly focused on modeling the COVID-19 pandemic to perform dynamic forecasting and analyze the effectiveness of control measures during the epidemic. Infectious disease dynamics offer good predictions for the early transmission trends of epidemics. However, this approach is unable to accurately estimate the spread of the virus in open-flow environments. Furthermore, it is also impossible to set hypothetical parameters, such as disease transmissibility and the recovery probability constant, that are consistent with the conditions in reality. Hence, with the increase in COVID-19 data, this approach has become inadequate for the accurate long-term analysis of epidemic trends.

Machine learning has shown significant advantages in this regard [ 20 , 21 ]. Some researchers have adopted the classic case-based reasoning approach in machine learning to make predictions. However, it is not feasible to find historical cases that fully match the current emergency event, so this approach has limited operability. Other researchers have also employed neural network training in machine learning to make predictions. For example, Hamou et al. predicted the number of injuries and deaths, which in turn were used to forecast the demand for emergency supplies [ 22 ]. However, this approach requires a large initial dataset and a high number of training epochs, while uncertainty due to large changes in intelligence information can lead to significant errors in data prediction [ 23 , 24 , 25 ]. To address these problems, researchers have conducted investigations that account (to varying degrees) for data characterized by time-series and non-linearity and have employed time-series models with good non-linear fitting [ 26 , 27 , 28 ]. The use of LSTM to explore relationships within the data can improve the accuracy of predicting COVID-19 to some extent. However, there are two problems with this approach. First, LSTM neural networks require extremely large datasets, and each wave of the epidemic development cycle would be insufficient to support a dataset suitable for LSTM. Second, neural networks involve a large number of parameters and highly complex models and, hence, are susceptible to overfitting, which can prevent them from achieving their true and expected advantages in prediction.

Overall, Our study differs from other papers in the following three ways. First, the research object of this paper focuses on the specific point of ICU healthcare resource demand prediction, aiming to improve the rate of critical care patient treatment. However, past research on public health emergencies has focused more on resource prediction , such as N95 masks, vaccines, and generalized medical supplies during the epidemic , to mitigate the impact of rapid transmission and high morbidity rates. This has led to less attention being paid to the reality of the surge in critically ill patients due to their high rates of severe illness and mortality.

Second, the idea of this paper is to further forecast resource needs based on the projected number of people with confirmed diagnoses, which is more applicable to healthcare organizations than most other papers that only predict the number of people involved. However, in terms of the methodology for projecting the number of people, this paper adopts a combined prediction method that combines regression algorithms and recurrent neural networks to propose a BILSTM-GASVR prediction model for the number of confirmed diagnoses. It capitalizes on both the suitability of SVR for small samples and non-linear prediction as well as the learning and memory abilities of BILSTM in processing time-series data. On the basis of the prediction model for the number of infected cases, by considering the characteristics of ICU healthcare resources, we constructed a demand forecasting model of emergency healthcare supplies. Past public health emergencies are more likely to use infectious disease models or a single prediction model in deep learning. some of the articles, although using a combination of prediction, but also more for the same method domain combination, such as CNN-LSTM, GRU-LSTM, etc., which are all recurrent neural networks.

Third, in terms of specific categorization of resources to be forecasted, considering the specificity of ICU medical resources, we introduce human resource prediction on the basis of previous studies focusing on material security, and classified ICU medical resources into three categories: ICU human resources, drugs and medical equipment. The purpose of this classification is to match the real-life prediction scenarios of public health emergencies and improve the demand forecasting performance for local ICU healthcare resources. Thus, it is easy for healthcare institutions to grasp the overall development of events, optimizing decision-making, and reducing the risk of healthcare systems collapsing during the outbreak stage.

In this section, we accomplish the following two tasks. Firstly, we introduce the idea of predicting the number of infected cases and show the principle of the relevant models. Secondly, based on the number of infected cases, ICU healthcare resources are divided into two categories (healthcare workers and healthcare supplies), and their respective demand forecasting models are constructed.

Prediction model for the number of infected cases

Gasvr model.

Support vector machine (SVM) is a machine-learning language for classification developed by Vapnik [ 29 ]. Suppose there are two categories of samples: H1 and H2. If hyperplane H is able to correctly classify the samples into these two categories and maximize the margin between the two categories, it is known as the optimal separating hyperplane (OSH). The sample vectors closest to the OSH in H1 and H2 are known as the support vectors. To apply SVM to prediction, it is essential to perform regression fitting. By introducing the \(\varepsilon\) -insensitive loss function, SVM can be converted to a support vector regression machine, where the role of the OSH is to minimize the error of all samples from this plane. SVR has a theoretical basis in statistical learning and relatively high learning performance, making it suitable for performing predictions in small-sample, non-linear, and multi-dimensional fields [ 30 , 31 ].

Assume the training sample set containing \(l\) training samples is given by \(\{({x}_{i},{y}_{i}),i=\mathrm{1,2},...,l\}\) , where \({x}_{i}=[{x}_{i}^{1},{x}_{i}^{2},...,{x}_{i}^{d}{]}^{\rm T}\) and \({y}_{i}\in R\) are the corresponding output values.

Let the regression function be \(f(x)=w\Phi (x)+b\) , where \(\phi (x)\) is the non-linear mapping function. The linear \(\varepsilon\) -insensitive loss function is defined as shown in formula ( 1 ).

Among the rest, \(f(x)\) is the predicted value returned by the regression function, and \(y\) is the corresponding real value. If the error between \(f(x)\) and \(y\) is ≤ \(\varepsilon\) , the loss is 0; otherwise, the loss is \(\left|y-f(x)\right|-\varepsilon\) .

The slack variables \({\xi }_{i}\) and \({\xi }_{i}^{*}\) are introduced, and \(w\) , \(b\) are solved using the following equation as shown in formula ( 2 ).

Among the rest, \(C\) is the penalty factor, with larger values indicating a greater penalty for errors > \(\varepsilon\) ; \(\varepsilon\) is defined as the error requirement, with smaller values indicating a smaller error of the regression function.

The Lagrange function is introduced to solve the above function and transformed into the dual form to give the formula ( 3 ).

Among the rest, \(K({x}_{i},{x}_{j})=\Phi ({x}_{i})\Phi ({x}_{j})\) is the kernel function. The kernel function determines the structure of high-dimensional feature space and the complexity of the final solution. The Gaussian kernel is selected for this study with the function \(K({x}_{i},{x}_{j})=\mathit{exp}(-\frac{\Vert {x}_{i}-{x}_{j}\Vert }{2{\sigma }^{2}})\) .

Let the optimal solution be \(a=[{a}_{1},{a}_{2},...,{a}_{l}]\) and \({a}^{*}=[{a}_{1}^{*},{a}_{2}^{*},...,{a}_{l}]\) to give the formula ( 4 ) and formula ( 5 ).

Among the rest, \({N}_{nsv}\) is the number of support vectors.

In sum, the regression function is as shown in formula ( 6 ).

when some of the parameters are not 0, the corresponding samples are the support vectors in the problem. This is the principle of SVR. The values of the three unknown parameters (penalty factor C, ε -insensitive loss function, and kernel function coefficient \(\sigma )\) , can directly impact the model effect. The penalty factor C affects the degree of function fitting through the selection of outliers in the sample by the function. Thus, excessively large values lead to better fit but poorer generalization, and vice versa. The ε value in the ε-insensitive loss function determines the accuracy of the model by affecting the width of support vector selection. Thus, excessively large values lead to lower accuracy that does not meet the requirements and excessively small values are overly complex and increase the difficulty. The kernel function coefficient \(\sigma\) determines the distribution and range of the training sample by controlling the size of inner product scaling in high-dimensional space, which can affect overfitting.

Therefore, we introduce other algorithms for optimization of the three parameters in SVR. Currently the commonly used algorithms are 32and some heuristic algorithms. Although the grid search method is able to find the highest classification accuracy, which is the global optimal solution. However, sometimes it can be time-consuming to find the optimal parameters for larger scales. If a heuristic algorithm is used, we could find the global optimal solution without having to trace over all the parameter points in the grid. And GA is one of the most commonly used heuristic algorithms, compared to other heuristic algorithms, it has the advantages of strong global search, generalizability, and broader blending with other algorithms.

Given these factors, we employ a GA to encode and optimize the relevant parameters of the model. The inputs are the experimental training dataset, the Gaussian kernel function expression, the maximum number of generations taken by the GA, the accuracy range of the optimized parameters, the GA population size, the fitness function, the probability of crossover, and the probability of mutation. The outputs are the optimal penalty factor C, ε-insensitive loss function parameter \(\varepsilon ,\) and optimal Gaussian kernel parameter \(\sigma\) of SVR, thus achieving the optimization of SVR. The basic steps involved in GA optimization are described in detail below, and the model prediction process is shown in Fig. 1 .

Prediction process of the GASVR model

Population initialization

The three parameters are encoded using binary arrays composed of 0–1 bit-strings. Each parameter consisted of six bits, and the initial population is randomly generated. The population size is set at 60, and the number of iterations is 200.

Fitness calculation

In the same dataset, the K-fold cross-validation technique is used to test each individual in the population, with K = 5. K-fold cross validation effectively avoids the occurrence of model over-learning and under-learning. For the judgment of the individual, this paper evaluates it in terms of fitness calculations. Therefore, combining the two enables the effective optimization of the model’s selected parameters and improves the accuracy of regression prediction.

Fitness is calculated using the mean error method, with smaller mean errors indicating better fitness. The fitness function is shown in formula ( 7 ) [ 32 ].

The individual’s genotype is decoded and mapped to the corresponding parameter value, which is substituted into the SVR model for training. The parameter optimization range is 0.01 ≤ C ≤ 100, 0.1 ≤ \(\sigma\) ≤ 20, and 0.001 ≤ ε ≤ 1.

Selection: The selection operator is performed using the roulette wheel method.

Crossover: The multi-point crossover operator, in which two chromosomes are selected and multiple crossover points are randomly chosen for swapping, is employed. The crossover probability is set at 0.9.

Mutation: The inversion mutation operator, in which two points are randomly selected and the gene values between them are reinserted to the original position in reverse order, is employed. The mutation probability is set at 0.09.

Decoding: The bit strings are converted to parameter sets.

The parameter settings of the GASVR model built in this paper are shown in Table 1 .

BILSTM model

The LSTM model is a special recurrent neural network algorithm that can remember the long-term dependencies of data series and has an excellent capacity for self-learning and non-linear fitting. LSTM automatically connects hidden layers across time points, such that the output of one time point can arbitrarily enter the output terminal or the hidden layer of the next time point. Therefore, it is suitable for the sample prediction of time-series data and can predict future data based on stored data. Details of the model are shown in Fig. 2 .

Schematic diagram of the LSTM model

LSTM consists of a forget gate, an input gate, and an output gate.

The forget gate combines the previous and current time steps to give the output of the sigmoid activation function. Its role is to screen the information from the previous state and identify useful information that truly impacts the subsequent time step. The equation for the forget gate is shown in formula ( 8 ).

Among the number, \(W_{f}\) is the weight of the forget gate, \({b}_{f}\) is the bias, \(\sigma\) is the sigmoid activation function, \({f}_{t}\) is the output of the sigmoid activation function, \(t-1\) is the previous time step, \(t\) is the current time step, and \({x}_{t}\) is the input time-series data at time step \(t\) .

The input gate is composed of the output of the sigmoid and tanh activation functions, and its role is to control the ratio of input information entering the information of a given time step. The equation for the input gate is shown in formula ( 9 ).

Among the number, \({W}_{i}\) is the output weight of the input gate, \({i}_{t}\) is the output of the sigmoid activation function, \({b}_{i}\) and \({b}_{C}\) are the biases of the input gate, and \({W}_{C}\) is the output of the tanh activation function.

The role of the output gate is to control the amount of information output at the current state, and its equation is shown in formula ( 10 ).

Among the number, \({W}_{o}\) is the weight of \({o}_{t}\) , and \({b}_{o}\) is the bias of the output gate.

The values of the above activation functions \(\sigma\) and tanh are generally shown in formulas ( 11 ) and ( 12 ).

\({C}_{t}\) is the data state of the current time step, and its value is determined by the input information of the current state and the information of the previous state. It is shown in formula ( 13 ).

Among the number, \(\widetilde{{C}_{t}}=\mathit{tan}h({W}_{c}[{h}_{t-1},{x}_{t}]+{b}_{c})\) .

\({h}_{t}\) is the state information of the hidden layer at the current time step, \({h}_{t}={o}_{t}\times \mathit{tan}h({c}_{t})\) .Each time step \({T}_{n}\) has a corresponding state \({C}_{t}\) . By undergoing the training process, the model can learn how to modify state \({C}_{t}\) through the forget, output, and input gates. Therefore, this state is consistently passed on, implying that important distant information will neither be forgotten nor significantly affected by unimportant information.

The above describes the principle of LSTM, which involves forward processing when applied. BILSTM consists of two LSTM networks, one of which processes the input sequence in the forward direction (i.e., the original order), while the other inputs the time series in the backward direction into the LSTM model. After processing both LSTM networks, the outputs are combined, which eventually gives the output results of the BILSTM model. Details of the model are presented in Fig. 3 .

Schematic diagram of the BILSTM model

Compared to LSTM, BILSTM can achieve bidirectional information extraction of the time-series and connect the two LSTM layers onto the same output layer. Therefore, in theory, its predictive performance should be superior to that of LSTM. In BILSTM, the equations of the forward hidden layer( \(\overrightarrow{{h}_{t}}\) ) , backward hidden layer( \(\overleftarrow{{h}_{t}}\) ) , and output layer( \({o}_{t}\) ) are shown in formulas ( 14 ) , ( 15 ) and ( 16 ).

The parameter settings of the BILSTM model built in this paper are shown in Table 2 .

Informer model

The Informer model follows the compiler-interpreter architecture in the Transformer model, and based on this, structural optimizations have been made to reduce the computational time complexity of the algorithm and to optimize the output form of the interpreter. The two optimization methods are described in detail next.

With large amounts of input data, neural network models can have difficulty capturing long-term interdependencies in sequences, which can produce gradient explosions or gradient vanishing and affect the model's prediction accuracy. Informer model solves the existential gradient problem by using a ProbSparse Self-attention mechanism to make more efficient than conventional self-attention.

The value of Transformer self-attention is shown in formula ( 17 ).

Among them, \(Q\in {R}^{{L}_{Q}\times d}\) is the query matrix, \(K\in {R}^{{L}_{K}\times d}\) is the key matrix, and \(V\in {R}^{{L}_{V}\times d}\) is the value matrix, which are obtained by multiplying the input matrix X with the corresponding weight matrices \({W}^{Q}\) , \({W}^{K}\) , \({W}^{V}\) respectively, and d is the dimensionality of Q, K, and V. Let \({q}_{i}\) , \({k}_{i}\) , \(v_{i}\) represent the ith row in the Q, K, V matrices respectively, then the ith attention coefficient is shown in formula ( 18 ) as follows.

Therein, \(p({k}_{j}|{q}_{i})\) denotes the traditional Transformer's probability distribution formula, and \(k({q}_{i},{K}_{l})\) denotes the asymmetric exponential sum function. Firstly, q=1 is assumed, which implies that the value of each moment is equally important; secondly, the difference between the observed distribution and the assumed one is evaluated by the KL scatter, if the value of KL is bigger, the bigger the difference with the assumed distribution, which represents the more important this moment is. Then through inequality \(ln{L}_{k}\le M({q}_{i},K)\le {\mathit{max}}_{j}\left\{\frac{{q}_{i}{k}_{j}^{\rm T}}{\sqrt{d}}\right\}-\frac{1}{{L}_{k}}{\sum }_{j=1}^{{L}_{k}}\left\{\frac{{q}_{i}{k}_{j}^{\rm T}}{\sqrt{d}}\right\}+ln{L}_{k}\) , \(M({q}_{i},K)\) is transformed into \(\overline{M}({q}_{i},K)\) . According to the above steps, the ith sparsity evaluation formula is obtained as shown in formula ( 19 ) [ 33 ].

One of them, \(M({q}_{i},K)\) denotes the ith sparsity measure; \(\overline{M}({q}_{i},K)\) denotes the ith approximate sparsity measure; \({L}_{k}\) is the length of query vector. \(TOP-u\) quantities of \(\overline{M}\) are selected to form \(\overline{Q}\) , \(\overline{Q}\) is the first u sparse matrices, and the final sparse self-attention is shown in Formula ( 20 ). At this point, the time complexity is still \(O({n}^{2})\) , and to solve this problem, only l moments of M2 are computed to reduce the time complexity to \(O(L\cdot \mathit{ln}(L))\) .

Informer uses a generative decoder to obtain long sequence outputs.Informer uses the standard decoder architecture shown in Fig. 4 , in long time prediction, the input given to the decoder is shown in formula ( 21 ).

Informer uses a generative decoder to obtain long sequence outputs

Therein, \({X}_{de}^{t}\) denotes the input to the decoder; \({X}_{token}^{t}\in {R}^{({L}_{token}+{L}_{y})\times {d}_{\mathit{mod}el}}\) is the dimension of the encoder output, which is the starting token without using all the output dimensions; \({X}_{0}^{t}\in {R}^{({L}_{token}+{L}_{y})\times {d}_{\mathit{mod}el}}\) is the dimension of the target sequence, which is uniformly set to 0; and finally the splicing input is performed to the encoder for prediction.

The parameter settings of Informer model created in this paper are shown in Table 3 .

BILSTM-GASVR combined prediction model

SVR has demonstrated good performance in solving problems like finite samples and non-linearity. Compared to deep learning methods, it offers faster predictions and smaller empirical risks. BILSTM has the capacity for long-term memory, can effectively identify data periodicity and trends, and is suitable for the processing of time-series data. Hence, it can be used to identify the effect of time-series on the number of confirmed cases. Given the advantages of these two methods in different scenarios, we combined them to perform predictions using GASVR, followed by error repair using BILSTM. The basic steps for prediction based on the BILSTM-GASVR model are as follows:

Normalization is performed on the initial data.

The GASVR model is applied to perform training and parameter optimization of the data to obtain the predicted value \(\widehat{{y}_{i}}\) .

After outputting the predicted value of GASVR, the residual sequence between the predicted value and real data is extracted to obtain the error \({\gamma }_{i}\) (i.e., \({\gamma }_{i}={y}_{i}-\widehat{{y}_{i}}\) ).

The BILSTM model is applied to perform training of the error to improve prediction accuracy. The BILSTM model in this paper is a multiple input single output model. Its inputs are the true and predicted error values \({\gamma }_{i}\) and its output is the new error value \(\widehat{{\gamma }_{i}}\) predicted by BILSTM.

The final predicted value is the sum of the GASVR predicted value and the BILSTM residual predicted value (i.e., \({Y}_{i}=\widehat{{y}_{i}}+\widehat{{\gamma }_{i}}\) ).

The parameter settings of the BILSTM-GASVR model built in this paper are shown in Table 4 .

Model testing criteria

To test the effect of the model, the prediction results of the BILSTM-GASVR model are compared to those of GASVR, LSTM, BILSTM and Informer. The prediction error is mainly quantified using three indicators: mean squared error (MSE), root mean squared error (RMSE), and correlation coefficient ( \(R^{2}\) ). Their respective equations are shown in formulas ( 22 ), ( 23 ) and ( 24 ).

Demand forecasting model of ICU healthcare resources

ICU healthcare resources can be divided into human and material resources. Human resources refer specifically to the professional healthcare workers in the ICU. Material resources, which are combined with the actual consumption of medical supplies, can be divided into consumables and non-consumables. Consumables refer to the commonly used drugs in the ICU, which include drugs for treating cardiac insufficiency, vasodilators, anti-shock vasoactive drugs, analgesics, sedatives, muscle relaxants, anti-asthmatic drugs, and anticholinergics. Given that public health emergencies have a relatively high probability of affecting the respiratory system, we compiled a list of commonly used drugs for respiratory diseases in the ICU (Table 5 ).

Non-consumables refer to therapeutic medical equipment, including electrocardiogram machines, blood gas analyzers, electrolyte analyzers, bedside diagnostic ultrasound machines, central infusion workstations, non-invasive ventilators, invasive ventilators, airway clearance devices, defibrillators, monitoring devices, cardiopulmonary resuscitation devices, and bedside hemofiltration devices.

The demand forecasting model of ICU healthcare resources constructed in this study, as well as its relevant parameters and definitions, are described below. \({R}_{ij}^{n}\) is the forecasted demand for the \(i\) th category of resources on the \(n\) th day in region \(j\) . \({Y}_{j}^{n}\) is the predicted number of current confirmed cases on the \(n\) th day in region \(j\) . \({M}_{j}^{n}\) is the number of ICU healthcare workers on the \(n\) th day in region \(j\) , which is given by the following formula: number of healthcare workers the previous day + number of new recruits − reduction in number the previous day, where the reduction in number refers to the number of healthcare workers who are unable to work due to infection or overwork. In general, the number of ICU healthcare workers should not exceed 5% of the number of current confirmed cases (i.e., it takes the value range [0, \(Y_{j}^{n}\) ×5%]). \(U_{i}\) is the maximum working hours or duration of action of the \(i\) th resource category within one day. \({A}_{j}\) is the number of resources in the \(i\) th category allocated to patients (i.e., how many units of resources in the \(i\) th category is needed for a patient who need the \(i\) th unit of the given resource). \({\varphi }_{i}\) is the demand conversion coefficient (i.e., the proportion of the current number of confirmed cases who need to use the \(i\) th resource category). \({C}_{ij}^{n}\) is the available quantity of material resources of the \(i\) th category on the \(n\) th day in region \(j\) . At the start, this quantity is the initial reserve, and once the initial reserve is exhausted, it is the surplus from the previous day. The formula for this parameter is given as follows: available quantity from the previous day + replenishment on the previous day − quantity consumed on the previous day, where if \({C}_{ij}^{n}\) is a negative number, it indicates the amount of shortage for the given category of resources on the previous day.

In summary, the demand forecast for emergency medical supplies constructed in this study is shown in formula ( 25 ).

The number of confirmed cases based on data-driven prediction is introduced into the demand forecasting model for ICU resources to forecast the demand for the various categories of resources. In addition to the number of current confirmed cases, the main variables of the first demand forecasting model for human resources are the available quantity and maximum working hours. The main variable of the second demand forecasting model for consumable resources is the number of units consumed by the available quantity. The main variable of the third model for non-consumable resources is the allocated quantity. These three resource types can be predicted using the demand forecasting model constructed in this study.

Prediction of the number of current infected cases

The COVID-19 situation in Shanghai is selected for our experiment. A total of 978 entries of epidemic-related data in Shanghai between January 20, 2020, and September 24, 2022, are collected from the epidemic reporting platform. This dataset is distributed over a large range and belongs to a right-skewed leptokurtic distribution. The specific statistical description of data is shown in Table 6 . Part of the data is shown in Table 7 .

And we divided the data training set and test set in an approximate 8:2 ratio, namely, 798 days for training (January 20, 2020 to March 27, 2022) and 180 days for prediction (March 28, 2022 to September 24, 2022).

Due to the large difference in order of magnitude between the various input features, directly implementing training and model construction would lead to suboptimal model performance. Such effects are usually eliminated through normalization. In terms of interval selection, [0, 1] reflects the probability distribution of the sample, whereas [-1, 1] mostly reflects the state distribution or coordinate distribution of the sample. Therefore, [-1, 1] is selected for the normalization interval in this study, and the processing method is shown in formula ( 26 ).

Among the rest, \(X\) is the input sample, \({X}_{min}\) and \({X}_{max}\) are the minimum and maximum values of the input sample, and \({X}_{new}\) is the input feature after normalization.

In addition, we divide the data normalization into two parts, considering that the amount of data in the training set is much more than the test set in the real operating environment. In the first step, we normalize the training set data directly according to the above formula; in the second step, we normalize the test data set using the maximum and minimum values of the training data set.

The values of the preprocessed data are inserted into the GASVR, LSTM, Informer, BILSTM models and the BILSTM-GASVR model is constructed. Figures 5 , 6 , 7 , 8 and 9 show the prediction results. From Figs. 5 , 6 , and 7 , it can be seen that in terms of data accuracy, GASVR more closely matches the real number of infected people relative to BILSTM and LSTM. Especially in the most serious period of the epidemic in Shanghai (April 17, 2022 to April 30, 2022), the advantage of the accuracy of the predicted data of GASVR is even more obvious, which is due to the characteristics of GASVR for small samples and nonlinear prediction. However, in the overall trend of the epidemic, BILSTM and LSTM, which have the ability to learn and memorize to process time series data, are superior. It is clearly seen that in April 1, 2022-April 7, 2022 and May 10, 2022-May 15, 2022, there is a sudden and substantial increase in GASVR in these two time phases, and a sudden and substantial decrease in April 10, 2022-April 14, 2022. These errors also emphasize the stability of BILSTM and LSTM, which are more closely matched to the real epidemic development situation in the whole process of prediction, and the difference between BILSTM and LSTM prediction is that the former predicts data more accurately than the latter, which is focused on the early stage of prediction as well as the peak period of the epidemic. Informer is currently an advanced time series forecasting method. From Fig. 8 , it can be seen that the prediction data accuracy and the overall trend of the epidemic are better than the single prediction models of GASVR, LSTM and BILSTM. However, Informer is more suitable for long time series and more complex and large prediction problems, so the total sample size of less than one thousand cases is not in the comfort zone of Informer model. Figure 9 shows that the BILSTM-GASVR model constructed in this paper is more suitable for this smaller scale prediction problem, with the best prediction results, closest to the actual parameter (number of current confirmed cases), demonstrating small sample and time series advantages. In Short, the prediction effect of models is ranked as follows: BILSTM-GASVR> Informer> GASVR> BILSTM> LSTM.

The prediction result of the GASVR model

The prediction result of the LSTM model

The prediction result of the BILSTM model

The prediction result of the Informer model

The prediction result of the BILSTM-GASVR model

The values of the three indicators (MSE, RMSE, and correlation coefficient \({R}^{2}\) ) for the five models are shown in Table 8 . MSE squares the error so that the larger the model error, the larger the value, which help capture the model's prediction error more sensitively. RMSE is MSE with a root sign added to it, which allows for a more intuitive representation of the order of magnitude difference from the true value. \({R}^{2}\) is a statistical indicator used to assess the overall goodness of fit of the model, which reflects the overall consistency of the predicted trend and does not specifically reflect the degree of data. The results in the Table 8 are consistent with the prediction results in the figure above, while the ranking of MSE, RMSE, and \({R}^{2}\) are also the same (i.e., BILSTM-GASVR> Informer> GASVR> BILSTM> LSTM).

In addition, we analyze the five model prediction data using significance tests as a way of demonstrating whether the model used is truly superior to the other baseline models. The test dataset with kurtosis higher than 4 does not belong to the approximate normal distribution, so parametric tests are not used in this paper. Given that the datasets predicted by each of the five models are continuous and independent datasets, this paper uses the Kruskal-Wallis test, which is a nonparametric test. The test steps are as follows.

Determine hypotheses (H0, H1) and significance level ( \(\alpha\) ).

For each data set, all its sample data are combined and ranked from smallest to largest. Then find the number of data items ( \({n}_{i}\) ), rank sum ( \({R}_{i}\) ) and mean rank of each group of data respectively.

Based on the rank sum, the test statistic (H) is calculated for each data set in the Kruskal-Wallis test. The specific calculation is shown in formula ( 27 ).

According to the test statistic and degrees of freedom, find the corresponding p-value in the Kruskal-Wallis distribution table. Based on the P-value, determine whether the original hypothesis is valid.

In the significance test, we set the significance setting original hypothesis (H0) as there is no significant difference between the five data sets obtained from the five predictive models. We set the alternative hypothesis (H1) as there is a significant difference between the five data sets obtained from the five predictive models. At the same time, we choose the most commonly used significance level taken in the significance test, namely 0.05. In this paper, multiple comparisons and two-by-two comparisons of the five data sets obtained from the five predictive models are performed through the SPSS software. The results of the test show that in the multiple comparison session, P=0.001<0.05, so H0 is rejected, which means that the difference between the five groups of data is significant. In the two-by-two comparison session, BILSTM-GASVR is less than 0.05 from the other four prediction models. The specific order of differences is Informer < GASVR < BILSTM < LSTM, which means that the BILSTM-GASVR prediction model does get a statistically significant difference between the dataset and the other models.

In summary, combined prediction using the BILSTM-GASVR model is superior to the other four single models in various aspects in the case study analysis of Shanghai epidemic with a sample size of 978.

Demand forecasting of ICU healthcare resources

Combined with the predicted number of current infected cases, representatives are selected from the three categories of resources for forecasting. The demand for nurses is selected as the representative for the first category of resources.

In view of the fact that there are currently no specific medications that are especially effective for this public health emergency, many ICU treatment measures involved helping patients survive as their own immune systems eliminated the virus. This involved, for example, administering antibiotics when patients developed a secondary bacterial infection. glucocorticoids are used to temporarily suppress the immune system when their immune system attacked and damaged lung tissues causing patients to have difficulty breathing. extracorporeal membrane oxygenation (ECMO) is used for performing cardiopulmonary resuscitation when patients are suffering from cardiac arrest. In this study, we take dexamethasone injection (5 mg), a typical glucocorticoid drug, as the second category of ICU resources (i.e., drugs); and invasive ventilators as the third category of ICU resources (i.e., medical equipment).

During the actual epidemic in Shanghai, the municipal government organized nine critical care teams, which are stationed in eight municipally designated hospitals and are dedicated to the treatment of critically ill patients. In this study, the ICU nurses, dexamethasone injections, and invasive ventilators in Shanghai are selected as the prediction targets and introduced into their respective demand forecasting models. Forecasting of ICU healthcare resources is then performed for the period from March 28, 2022, to April 28, 2022, as an example. Part of the parameter settings for the three types of resources are shown in Tables 9 , 10 , and 11 , respectively.

Table 12 shows the forecasting results of the demand for ICU nurses, dexamethasone injections, and invasive ventilators during the epidemic wave in Shanghai between March 28, 2022, and April 28, 2022.

For the first category (i.e., ICU nurses), human resource support is only needed near the peak period, but the supply could not be replenished immediately. In the early stages, Shanghai could only rely on the nurses’ perseverance, alleviating the shortage of human resources by reducing the number of shifts and increasing working hours. This situation persisted until about April 10 and is only resolved when nurses from other provinces and regions successively arrived in Shanghai.

The second category of ICU resources is drugs, which are rapidly consumed. The pre-event reserve of 30,000 dexamethasone injections could only be maintained for a short period and is fully consumed during the outbreak. Furthermore, daily replenishment is still needed, even when the epidemic has passed its peak and begun its decline.

The third category is invasive ventilators, which are non-consumables. Thus, the reserve lasted for a relatively long period of time in the early stages and did not require replenishment after its maximum usage during the peak period.

Demand forecasting models are constructed based on the classification of healthcare resources according to their respective features. We choose ICU nurses, dexamethasone injections, and invasive ventilators as examples, and then forecast demand for the epidemic wave in Shanghai between March 28, 2022, and April 28, 2022. The main conclusions are as follows:

A long period of time is needed to train ICU healthcare workers who can independently be on duty, taking at least one year from graduation to entering the hospital, in addition to their requiring continuous learning, regular theoretical training, and the accumulation of clinical experience during this process. Therefore, for the first category of ICU healthcare resources, in the long term, healthcare institutions should place a greater emphasis on their talent reserves. Using China as an example, according to the third ICU census, the ratio of the number of ICU physicians to the number of beds is 0.62:1 and the ratio of the number of nurses to the number of beds is 1.96:1, which are far lower than those stipulated by China itself and those of developed countries. Therefore, a fundamental solution is to undertake proactive and systematic planning and construction to ensure the more effective deployment of human resources in the event of a severe outbreak. In the short term, healthcare institutions should focus on the emergency expansion capacity of their human resources. In case there are healthcare worker shortages during emergencies, the situation can be alleviated by summoning retired workers back to work and asking senior medical students from various universities to help in the hospitals to prevent the passive scenario of severely compressing the rest time of existing staff or waiting for external aid. However, it is worth noting that to ensure the effectiveness of such a strategy of using retired healthcare workers or senior students of university medical faculties, it is necessary for healthcare organizations to provide them with regular training in the norm, such as organizing 2-3 drills a year, to ensure the professionalism and proficiency of healthcare workers who are temporarily and suddenly put on the job. At the same time, it is also necessary to fully mobilize the will of individuals. Medical institutions can provide certain subsidies to retired health-care workers and award them with honorable titles. For senior university medical students, volunteer certificates are issued and priority is given to their internships, so that health-care workers can be motivated to self-realization through spiritual and material rewards.

Regarding the second category of ICU resources (i.e., drugs), healthcare institutions perform the subdivision of drug types and carry out dynamic physical preparations based on 15–20% of the service recipient population for clinically essential drugs. This will enable a combination of good preparedness during normal times and emergency situations. In addition, in-depth collaboration with corporations is needed to fully capitalize on their production capacity reserves. This helps medical institutions to be able to scientifically and rationally optimize the structure and quantity of their drug stockpiles to prevent themselves from being over-stressed. Yet the lower demand for medicines at the end of the epidemic led to the problem of excess inventory of enterprises at a certain point in time must be taken into account. So, the medical institutions should sign a strategic agreement on stockpiling with enterprises, take the initiative to bear the guaranteed acquisition measures, and consider the production costs of the cooperative enterprises. These measures are used to truly safeguard the enthusiasm of the cooperative enterprises to invest in the production capacity.

Regarding the third category of ICU resources (i.e., medical equipment), large-scale medical equipment cannot be rapidly mass-produced due to limitations in the capacity for emergency production and conversion of materials. In addition, the bulk procurement of high-end medical equipment is also relatively difficult in the short term. Therefore, it is more feasible for healthcare institutions to have physical reserves of medical equipment, such as invasive ventilators. However, the investment costs of medical equipment are relatively high. Ventilators, for example, cost up to USD $50,000, and subsequent maintenance costs are also relatively high. After all, according to the depreciable life of specialized hospital equipment, the ventilator, as a surgical emergency equipment, is depreciated over five years. And its depreciation rate is calculated at 20% annually for the first five years, which means a monthly depreciation of $835. Thus, the excessively low utilization rate of such equipment will also impact the hospital. Healthcare institutions should, therefore, conduct further investigations on the number of beds and the reserves of ancillary large-scale medical equipment to find a balance between capital investment and patient needs.

The limitations of this paper are reflected in the following three points. Firstly, in the prediction of the number of infections, the specific research object in this paper is COVID-19, and other public health events such as SARS, H1N1, and Ebola are not comparatively analyzed. The main reason for this is the issue of data accessibility, and it is easier for us to analyze events that have occurred in recent years. In addition, using the Shanghai epidemic as a specific case may be more representative of the epidemic situation in an international metropolis with high population density and mobility. Hence, it has certain regional limitations, and subsequent studies should expand the scope of the case study to reflect the characteristics of epidemic transmission in different types of urban areas and enhance the generalizability.

Secondly, the main emphasis of this study is on forecasting the demand for ICU healthcare resources across the entire region of the epidemic, with a greater focus on patient demand during public emergencies. Our aims are to help all local healthcare institutions more accurately identify changes in ICU healthcare resource demand during this local epidemic wave, gain a more accurate understanding of the treatment demands of critically ill patients, and carry out comprehensive, scientifically based decision-making. Therefore, future studies can examine individual healthcare institutions instead and incorporate the actual conditions of individual units to construct multi-objective models. In this way, medical institutions can further grasp the relationship between different resource inputs and the recovery rate of critically ill patients, and achieve the balance between economic and social benefits.

Finally, for the BILSTM-GASVR prediction method, in addition to the number of confirmed diagnoses predicted for an outbreak in a given region, other potential applications beyond this type of medium-sized dataset still require further experimentation. For example, whether the method is suitable for procurement planning of a certain supply in production management, forecasting of goods sales volume in marketing management, and other long-period, large-scale and other situations.

Within the context of major public health events, the fluctuations and uncertainties in the demand for ICU resources can lead to large errors between the healthcare supply and actual demand. Therefore, this study focuses on the question of forecasting the demand for ICU healthcare resources. Based on the number of current confirmed cases, we construct the BILSTM-GASVR model for predicting the number of patients. By comparing the three indicators (MSE, MAPE, and correlation coefficient \(R^{2}\) ) and the results of the BILSTM, LSTM, and GASVR models, we demonstrate that our model have a higher accuracy. Our findings can improve the timeliness and accuracy of predicting ICU healthcare resources and enhance the dynamics of demand forecasting. Hence, this study may serve as a reference for the scientific deployment of ICU resources in healthcare institutions during major public events.

Given the difficulty in data acquisition, only the Shanghai epidemic dataset is selected in this paper, which is one of the limitations mentioned in Part 4. Although the current experimental cases of papers in the same field do not fully conform to this paper, the results of the study cannot be directly compared. However, after studying the relevant reviews and the results of the latest papers, we realize that there is consistency in the prediction ideas and prediction methods [ 34 , 35 ]. Therefore, we summarize the similarities and differences between the results of the study and other research papers in epidemic forecasting as shown below.

Similarities: on the one hand, we all characterize trends in the spread of the epidemic and predict the number of infections over 14 days. On the other hand, we all select the current mainstream predictive models as the basis and combine or improve them. Moreover, we all use the same evaluation method (comparison of metrics such as MSE and realistic values) to evaluate the improvements against other popular predictive models.

Differences: on the one hand, other papers focus more on predictions at the point of the number of patients, such as hospitalization rate, number of infections, etc. This paper extends the prediction from the number of patients to the specific healthcare resources. This paper extends the prediction from the number of patients to specific healthcare resources. We have divided the medical resources and summarized the demand regularities of the three types of information in the epidemic, which provides the basis for decision-making on epidemic prevention to the government or medical institutions. On the other hand, in addition to the two assessment methods mentioned in the same point, this paper assesses the performance of the prediction methods with the help of significance tests, which is a statistical approach to data. This can make the practicality of the forecasting methodology more convincing.
