The exploratory function of case studies has been widely recognized by the academic circles at home and abroad, but there are still many doubts about the universality of the research conclusions. Based on the understanding of the universal function of research and extrapolation, this paper discusses the extrapolation of case studies and responds to the key questions such as whether case studies need extrapolation, whether case studies can achieve extrapolation and what are the applicable conditions of extrapolation in turn. First of all, through the understanding of the case study extrapolation context, it is found that the more complex the context is, the weaker the universality of the research conclusion. In addition to the constraints of the complex context, the case study is more likely to cause the universality issue due to the small number of samples, and it is concluded that the extrapolation of the case study is extremely necessary. Secondly, through the in-depth analysis of the case study extrapolation context, it shows that although a case study is in a complex context, it can be generalized as universal constructs or in a simplified context combination through induction, thus laying the basis and conditions for extrapolation, and reaching the conclusion that a case study can achieve extrapolation on the basis of similar contexts. Thirdly, by discussing the boundary and scope of case study extrapolation, this study finds out the research objects under the homogenous contextual characteristics and similar contextual combinations, and the applicable theory can be compared and discussed, and concludes that the applicable conditions of case study extrapolation mainly include contextual feature mining and dynamic contextual combinations. Finally, in order to ensure the implementation of case study extrapolation, the process of extrapolation is further refined into basic and extended extrapolations, which provides references and suggestions for scholars to carry out case studies with universal values, and facilitates the vigorous development of management studies in China.
