论文概念辨析：Introduction 和 Problem Statement 有什么区别？
The Introduction is the first section of a research paper and provides background for the study. The purpose of an Introduction is to engage the readers and give them the essential background information they need to understand the aim of your study. The Introduction includes the study background and the research question.
A problem statement, on the other hand, is an essential part of a research proposal, which is written to acquire funding for your research. It is a brief explanation of an issue, a condition, or a situation that you wish to study. It helps you clearly identify the purpose of your project by highlighting the gap between an ideal situation and the reality, and why it is important to bridge that gap. Clearly defining the problem that your research will address is essential to convince the funders that your project is worth funding.
Writing a problem statement comes at a much earlier stage in your research journey, after you have chosen the area in which you would like to conduct your research (or the gap you would like to address through your research) and are seeking research funding. In contrast, the Introduction is written after you have completed your research and are presenting your findings for publication.
In sum, the Introduction provides background information, includes a literature review, explains the purpose of your study, and states the research question, and the problem statement gives an overview of the specific problem that your research will address.
