Case study method, as its name implies, refers to the research method to solve related problems through investigation and analysis of cases.
The research object of literature research method is "literature", and the research object of case study method is of course "case". The scope of cases includes individuals, groups, organizations, events, problems, phenomena and so on. It is a very important research method in academic research, and the research is concrete and meticulous.
Case study method is aimed at "individual" research. In the process of research, there are more or less differences between individuals and the whole, which will show particularity. Therefore, case analysis inevitably has typical characteristics when analyzing individuals and majors.
In-depth: the research content involved in case study is more in-depth: the basic information and historical data of the case need to be tracked during the research process. In this case, our research on individual cases is getting deeper and deeper with the passage of time, and the research data we have is more comprehensive.
Limitations: In addition to its typicality and depth, the case study still has some shortcomings. Limitation is its biggest flaw. Due to the small number of case studies, it is difficult to cover the whole, and the conclusions drawn from the study are difficult to be effectively applied to regular conclusions, which is not suitable for theoretical construction.
