Abstract: After the integration of Yangtze River Delta was elevated and developed into a national strategy, few domestic studies have been conducted to explore the integrated and collaborative development of biopharmaceutical industry in the Yangtze River Delta region, which, as an important region of biopharmaceutical industry in China, has initially formed the development mode of industrial clusters. In this study, based on the industry-university-research model of patent and fund project cooperation, the social network analysis (SNA) method is used to analyze and study the cooperation of patent and Major Projects of National Natural Science Foundation of China in the biopharmaceutical industry in the Yangtze River Delta region. The study shows that the industry-university-research cooperation in the biomedical field in the Yangtze River Delta region is still in the development stage and the degree of integration needs to be improved. Universities and research institutes are more inclined to cooperate with enterprises for invention patents and with other universities for fund project research.It is suggested that the Yangtze River Delta region should adopt the deep integration mode of industry-university-research, relevant leading scientific research institutions should establish open innovation platforms, and pharmaceutical universities should cultivate innovative talents with the advantages of their disciplines, and adopt "Revealing the List and Taking Command" or other ways to tackle key core technologies.
