Abstract: The government supports the corporation innovation through direct R&D subsidies, tax exemption and policy inducement. However, there is litter literature pay attention to the efficiency of government R&D support. This article proposes a three-stage DEA model based on Super-SBM method to measure the efficiency of government R&D support and find out that technological and operational capability among factors of enterprises as well as characteristics of corporations among factors of external environment exert tremendous influences on the input and/or output slacks. With the help from econometrics technique, we shed more light on the effect of enterprises’ R&D expenditure on the efficiency of government R&D support. After controlling the ratio of government R&D subsidies to enterprises’ R&D input, the R&D input itself perform positive influence on efficiency of government R&D support, while the ratio plays a negative moderating role in this relationship. it concludes by presenting that government should the ratio lower than a certain value; only if the R&D input lower than the critical value can the government increase that ratio favorably.
