Literature review is a specific process in which the author comprehensively sorts out, selects, introduces and comments the collected academic information and research methods on the basis of extensive reading in this discipline, so as to show the author's research vision, special research perspective and theoretical innovation while grasping the latest progress and development trend at home and abroad. First, the basic writing steps 1. The collection of literature materials is the basic basis for writing literature review. The topic selection and writing of the thesis need to collect and read a large number of domestic and foreign related documents, which can be consulted through China Journal Network, VIP and other websites or libraries at all levels. Try to collect and select the latest related research results, and select the best research products from near to far. For those authoritative and representative documents, we should study them repeatedly, understand their essence, examine their gains and losses, and integrate them for our use. 2. Accumulate reference materials, and arrange reading documents at any time. For published papers, download the full text (to China Journal Network or VIP website) or copy the full text (library); For publicly published books, the author, publishing house, publication time, book classification number and collection place in the library should be recorded, and relevant contents can be copied if necessary. We should carefully study the discovered literature, especially the authoritative and representative literature, and understand its essence; The important viewpoints and expositions in the literature should be refined, analyzed and synthesized, classified according to the problems studied or discussed, summarized according to the content, and classified separately. 3. Writing of Literature Review After reading a lot of literature, refining and enriching your own research topics, you can write a literature review. According to the writing outline, we can adjust the structure of the article, improve the viewpoint and supplement the content as needed in the writing process. After the completion of the first draft, we should review, revise and supplement it repeatedly, and pay attention to whether the viewpoint is consistent with the content of the topic, whether the structure is unified, and whether the data and words are wrong. Strive to achieve clear themes, clear concepts, rigorous logic, clear levels, refined words and accurate expression. Second, literature collection skills 1. It is a rigorous and responsible research attitude to choose mainstream literature and collect literature extensively, but if there is no standard and improper selection, it will consume valuable time and energy for a large number of mixed literature. Therefore, literature selection should focus on the core journals, classic works, research reports of full-time departments and other mainstream literature in this field, and try to consult authoritative and representative literature, such as the relevant expositions of famous people at home and abroad. 2. To reflect the latest research literature review, we should introduce valuable and up-to-date academic literature to reflect the cutting-edge research of this discipline, master the latest viewpoints, methods and their existing problems or research deficiencies, and clarify the value and innovation of our own research. III. Basic Precautions 1. Publishing one's own opinions and literature review cannot simply copy other people's research results or ready-made conclusions. It is necessary to take out the author's own inductive comments on the literature, analyze and investigate, and show his own views. 2. Respect for the content of the original literature review should be based on the original literature. When collecting data, if you find meaningful quotations, you must find the original documents, and you can't use indirect documents for convenience. Because indirect literature may make mistakes in the process of citation, so that it spreads from error to error. 3. Literature review closely related to the subject is an important symbol of comprehensively grasping the research overview of a specific professional field, and it is a comprehensive and concise refinement of professional literature, which can reflect the latest academic information, research results and research methods, and put forward its own views and ideas.
