China's generic drug industry has made great progress in recent years and become an important player in the global generic drug market. In this study, CNKI was used as the data source, and Clustering and Cosine similarity algorithms were invoked to explore the development trend and research hotspots in the field of generic drugs in China, and the authors, issuing organizations, keywords, etc. of the screened eligible literature were analyzed for co-occurrence, and the knowledge map was drawn, and a total of 1,749 articles were included in the screened literature. The results show that the annual publication number of literature overall fluctuating growth trend. The authors of the publications mainly include Xu Mingyi, Shao Rong, and Niu Jianzhao, and the institutions are mainly China Academy of Food and Drug Control and China Pharmaceutical University. The research hotspots mainly focus on generic drugs, original drugs, drug registration, etc., of which band purchasing is the focus of generic drug research in recent years. The overall development of domestic generic drug research is good, but the influence of the published papers is insufficient. The cooperation between authors is relatively close, but the cross-institutional research cooperation needs to be strengthened.
