Abstract

Based on the starting point of enterprise as the mainstay of technological innovation, the stochastic frontier analysis (SFA) method was used to calculate the innovation efficiency and non efficiency factors. The results show that cooperation between major actors and the absorption ability has a positive influence on innovation efficiency, but the patent stock that enterprise owns and the import of technology has a negative influence on innovation efficiency. The regional innovation efficiency of China presents rising trend on the whole, and the innovation efficiency value fluctuates between 0.3~0.5, and there is still larger room for improvement in the future.
