Abstract: The R&D efficiency in the various regions of China is evaluated and the spatial R&D efficiency patterns are summarized by means of the super-efficiency DEA model. In the meantime, a convergence approach is applied to analyze the temporal-spatial evolution features of R&D efficiency. Finally the reasons for the R&D efficiency difference between regions are studied using the spatial econometric models. The results are listed as follows: The features of "club convergence" are presented among the regions,in which different regions converge to the different equilibrium levels; Geographic R&D efficiency spillovers between adjacent regions really exist; The factors of FDI,foreign trade,and human capital have positive impacts on the R&D efficiency; The spillover effects from the FDI and foreign trade could be strengthened by the human capital accumulation. Therefore, according to the status quo of R&D activity, local governments should strengthen the R&D cooperation between adjacent regions to achieve the optimal allocation of R&D resources.

Key words: R&D efficiency, spillover effect, spatial dependence
