Abstract: Technology present situation and problem, source of technology acquisition, and relationship between social network and technology acquisition are analyzed using Zhejiang province small and mini-sized enterprises as the sample. The results show that, the level of technology is not high with a lack of R&D investment; the technology acquisition is mainly based on external source, with the serious problem of technology stealing; there are differences among the effects of social network (including friends network, public network, experts network and market network) on technology acquisition, which market network is the most significant. Therefore, small and mini-sized enterprises should gradually transform from the external technology imitation and import to the internal technology absorption and development, at the same time, they should also build technology innovation network to realize synergy innovation and technology upgrading.
