Literature review refers to sorting out, summarizing, summarizing and evaluating the existing research status of a certain field or a certain problem at home and abroad, which is one of the necessary links of scientific research. It usually consists of four parts: introduction, text, conclusion and references. The introduction part mainly expounds the research object, research purpose, research significance and methods of this paper. Through the introduction, readers can quickly understand the issues to be discussed and concerned in the article.
The body part is the core part of literature review, which requires a comprehensive investigation, collation and summary of the existing research. These studies may be published in famous academic journals, important academic conferences, professional books, master's and doctoral dissertations at home and abroad. The content of the text can include the discussion of the research objects, research methods, research achievements and limitations of the existing research, as well as the analysis, classification, comparison, summary and evaluation of these studies.
The conclusion part summarizes the existing research, highlighting the contributions and shortcomings of the existing research in academic value, research significance, theoretical construction and practical application. At the same time, the conclusion of the literature review can also explain the innovation, significance and difficulty of the research.
Reference is the most important part of literature review, covering all the detailed information about the source, author, title and publication time. References need to be arranged according to the corresponding paper format specification to ensure the readability and traceability of the article.
Literature review can include the following contents:
1, the research object, purpose, methods, samples, data sources and other information of the existing research.
2. Advantages and disadvantages of existing research in academic contribution, research value, theoretical construction and practical application.
3. Information such as differences, connections and innovations between existing research and own research.
The importance of literature review
1. In-depth understanding of the existing research status and trends: Through literature review, understanding the research status and frontiers of academic circles in a certain field or a certain problem at home and abroad will help to deeply understand the existing research progress and trends in related fields and provide guidance and reference for their own research.
2. Accurate positioning of scientific problems: By consulting and analyzing the existing research, we can quickly understand the basic situation of a certain problem in the vast literature, thus positioning scientific research problems more accurately, narrowing the research direction and thinking, and improving research efficiency.
3. Improve the research credibility and scientific research level: Literature review needs to be based on in-depth research, systematic summary and reasonable evaluation of a large number of documents, provide researchers with sufficient academic knowledge reserves and material support, and improve the research credibility and scientific research level.
