Abstract In this paper,the SBM-Undesirable model is adopted to measure the innovation efficiency of Chinese provincial high-tech industries,then the system GMM is employed to test how local technology transfer can enhance innovation efficiency of high-tech industries,and explorations are made respectively in the interactions between local technology transfer and foreign technology import or foreign direct investment and in their influence on the innovation efficiency.The results show that local technology transfer not only can directly enhance innovation efficiency of high-tech industries,but can indirectly enhance the efficiency through its complementary effect on foreign technology import.FDI has a substitution effect on local technology transfer and suppresses independent innovation of high-tech industries in China.
