Abstract: Abstract Technology transaction is the main form of the transformation of innovation achievements. Studying the impact of multidimensional proximity on technology transaction can reveal the internal driving force of the current technology transaction relationship, and provide a theoretical basis for fomulating achievement transformation policy. Based on the Chinese integrated circuit patent transfer data, this paper uses the exponential random graph model (ERGM) to analyze the influence of multidimensional proximity and endogenous structural dependence of transaction entities on the formation of technical transaction relationships.The results show that geographical proximity has no obvious effect on technology transactions; technology and institutional proximity have only begun to affect technology transactions in the last three years; the proportion of organizational proximity has gradually increased; Social proximity has been playing a more stable role in promoting technology transactions. At the same time, research on the endogenous structure dependence of the network finds that enterprises tend to establish links with entities which have active transaction behavior; enterprises with direct transaction relationships will complete secondary transactions through indirect contacts, while enterprises with indirect links will not establish a direct transaction relationship actively .This conclusion verifies the influencing factors of technology transaction, which is helpful to guide industrial innovation and improve the the rate of technology transfer.
