We should insist on choosing topics with scientific value and practical significance. The purpose of scientific research is to better understand and transform the world, thus promoting the continuous progress and development of society. Therefore, the topic selection of graduation thesis must be closely combined with the needs of socialist material civilization and spiritual civilization construction, with promoting the development of scientific undertakings and solving practical problems as the starting point and destination. The topic selection should conform to the correct direction of scientific research, be novel and innovative, and have theoretical value and practical guiding significance or promoting effect. A meaningless research, even if it takes a lot of energy and the expression is perfect, is worthless. Specifically, candidates can choose topics from the following three aspects. First of all, we should choose a topic from the disadvantages of reality and learn professional knowledge. We should not only stay in books and theories, but also try to integrate theory with practice and use our professional knowledge to find and solve problems that need to be solved urgently in work practice. Secondly, we should choose topics from the blank and marginal fields of scientific research. There are still many virgin lands in scientific research, and there are still many defects and gaps to be filled. Candidates should have unique vision and advanced consciousness to think, discover and study. Finally, we should choose the topic from finding the shortcomings and mistakes of previous studies. Many of the research topics put forward by predecessors have achieved initial research results, but with the continuous development of society, they still need to be enriched, improved and developed. This supplementary or revised research topic also has scientific value and practical guiding significance.
