Literature review, referred to as review for short, is an academic paper that collects a large number of relevant materials in a certain field or discipline, reveals the new trends, new trends and new principles of related issues through reading, sorting, analyzing and refining, and finds the breakthrough point and breakthrough point for the follow-up research. Summary seems simple, but in fact it is an arduous task. You need a lot of practical work experience in this field to know the advantages and disadvantages of various technical routes, and you also need a far-sighted strategic vision. In foreign countries, macro or systematic literature review is usually done by top "big cows" in a certain field.

The writing steps of literature review can generally be divided into literature collection, literature reading and classification, literature processing, comparison and comment; The research trend is predicted, and the problems to be studied are put forward [1].

( 1)? Document collection. In terms of quantity, sufficient preparation is needed; From a qualitative point of view, certainty is needed.

(2)? Reading and classification of documents. We should read the selected representative documents "critically and intensively". Secondly, it is classified according to certain standards, so as to be used in the follow-up research. Common ones are classified by subject field, and also by academic viewpoint and academic genre.

(4)? Forecast research trends. Summarize the main research results at home and abroad and their application value, point out the main problems at present, and look forward to the future development trend or prospect.

difficulty

A good literature review should be both strategic and down-to-earth; It's like exploring the hidden world, and it's like enlightening. Literature review, as its name implies, consists of "synthesis" and "narration". The first half of "synthesis" is not too difficult, if we can comprehensively classify, refine and summarize according to a large number of documents consulted. The comment, description and analysis in the second half are the dividing line of a summary, which needs to be integrated into the author's own theoretical level, professional foundation, ability to analyze and solve problems, and put forward his own unique views on the basis of reasonable analysis of the problems.

Common problems in literature review

(1) A large number of articles are listed and piled up, mistakenly thinking that the purpose of literature review is to show the understanding of its related research. Therefore, many literature reviews are not centered on the problems studied, but become a list of reading experiences.

(2) Selective literature review, some authors do not systematically review the literature, but choose to review the literature for some reason, which makes the review a reflection of the author's subjective wishes and loses objectivity and impartiality.

(3) There are too many listed documents and improper references. The documents required to be recorded in the review should be the original documents read by the author himself, but all the read documents should not be listed, and the representative and latest documents should be selected.
