OBJECTIVE：To study industry-university-resear ch cooperation model and network evolution characteristics of pharmaceutical manufacturing industry in China ，and to provide decision-making basis for pharmaceutical innovation cooperation. METHODS：Using social network analysis method ，based on industry-university-research cooperation patent data of pharmaceutical manufacturing industry during 1998-2019，the patent cooperation network of pharmaceutical manufacturing industry in China was established，and the structural parameters were calculated and evolution regularity of the network were analyzed. RESULTS ： Industry-university-research cooperation patents in the pharmaceutical manufacturing industry were affected by drug innovation policies. The scale of innovation network in pharmaceutical manufacturing industry was expanding day by day ；the density of innovation network was decreasing gradually ；it was not characterized with typical small world features. CONCLUSIONS ：It is suggested to strengthen the scientific and technological support to the core innovation subjects （universities and research institutions），and improve the cooperation with enterprises ；optimize the drug innovation policy environment ，encourage more innovation subjects to participate in the drug R&D process ；construct a platform for industry-university-research collaborative innovation，build drug R&D mechanism which can promote industry-university-research cooperation ，reduce the number of intermediaries in cooperation ，optimize the allocation of drug R&D resources and promote cooperative innovation of enterprises.
