Outline
This article reviews and analyzes the process of pharmaceutical innovation research in China to understand the frontier and hot spots of pharmaceutical innovation research, in order to provide reference for future research and practice. The relevant documents were searched in database CNKI, and CiteSpace visualization software was used to visually analyze and compare the selected documents, such as organization and author, keyword co-occurrence and clustering, keyword timeline and burst detection. A total of 2 255 literatures were included in this study. The results showed that the articles published on pharmaceutical innovation research has increased in volatility in the past 3 decades, and intuitively showed that the main affiliations, authors and major journals in this research field have not formed research clusters, and the institutional cooperation of scholars is limited. There are 10 clusters of high-frequency keywords, which are consistent with the development trend of pharmaceutical innovation. The emergence of 23 high-frequency keywords represents the research frontier in the field of pharmaceutical innovation. The cooperation density between institutions and authors remains a relatively low level, and a stable cooperative network relationship has not been formed between authors and institutions. In terms of research content, the development stage of China's pharmaceutical innovation research is consistent with the development of medicine, and the research content and field need to go further. The management performance and efficiency of pharmaceutical innovation and the cultivation of pharmaceutical innovation talents are more important research contents in recent years. There is still a large development space in pharmaceutical innovation research.
