Abstract Constructing an efficient cooperation network is the key to break through the research and development (R&D) problems of the key generic purpose technology.It is of great significance for the development of cooperation network to reveal the evolution mechanism of cooperation network.Based on social network theory and random statistics theory, this study summarizes the driving factors of the evolution of the technology cooperation network as attribute-driven, homophily-driven and structure-driven.Based on the cooperative patent data of the key generic purpose technology in the pharmaceutical industry, the technology cooperation network is constructed to analyze the evolution characteristics of the network, and the driving mechanism of the network evolution is explored by using the ERGM.The results show that with the evolution of the network, only a few R&D entities carry out extensive and frequent cooperation.The R&D capability and structural hole attributes of R&D entities have no obvious effect on the evolution of the technology cooperation network, but the degree centrality has a significant effect on the network evolution.The network evolution has obvious geographical and organizational homogeneity effects.The network tends to form star structure and closed triangle structure rather than open triangle structure.
