Abstract: Based on measuring the university technology transfer efficiency of 31 provinces in China during 2005-2011 using DEA method, this paper investigates the regional differences and the convergence of the university technology transfer efficiency, analyzes the effects of the subject, the relation and the environment on the university technology transfer efficiency using panel tobit model. The results show, the university technology transfer efficiency in China is relatively low, no significant improvement, and has a convergent trend as a whole. The promotion of the university, the relation between the university and the firm, regional GDP have significant positive influence on the university technology transfer efficiency. The supports of the government, the relation between the government and the university, the absorptive capacity of the regional firm have no significant influence on the university technology transfer efficiency. Finally, this paper gives some policy recommendations.
