The topic should not be too big. Don't always analyze the industry and so on. The research topic, whether undergraduate or master's thesis, should focus on a point and peep at some problems in a certain field from a point. Too big will inevitably lead to uncontrollable content, and finally it can only be generalized. Second, you can't be too old. You can't always say that the topic should be timely. For example, it can't be 2022 now. If you study things in 2000, they are usually topics within three years. Specific to the topic of the paper, if there are specific topics, such as case analysis, event analysis and so on. These topics should have happened in recent years. Third, we should innovate, but we should also consider the acquisition of information. In one case, some students choose a very unpopular topic in pursuit of innovation, which will lead to writing papers without clear and effective information support, and it is very difficult to write. Therefore, before making a decision, it is basically necessary to know whether there are corresponding materials to support the creation.
