Abstract: Based on the patent transaction data of China's smartphone industry from 2002 to 2016, through the smart phone industry technology development is divided into the budding period, the emergence and stability period, this study examines the role of geographic, technological and institutional proximity in the evolution of the technology transaction networks of different stages. The empirical results based on QAP network regression method show that the effect of geographic, technological and institutional proximity on the inter-organization technology transaction network is positive and stable, but with the development of industrial technology from the budding stage to the stable stage, the degree of geographical proximity's effect is weakened, and the degree of the technological proximity's effect is enhanced and then weakened, and the degree of the institutional proximity ' effect is not significant. This study extends the theory of proximity to the inter-organization technology transaction network driving mechanism from the perspective of technology life cycle.
