In order to obtain contribution of each innovation factor to efficiency of technological innovation, the paper distinguishes basic research, applied research and experimental development, and estimates the single factor efficiency of each innovation factor based on the stochastic frontier production function. The estimation results show that the single factor efficiency of basic research is higher than applied research's and experimental development's, R&D funds' efficiency in basic research and applied research is higher than R&D scientific and technical personnel's efficiency, but R&D scientific and technical personnel's efficiency is higher than R&D funds' efficiency in experimental development. Efficiency of scientific papers and patents as factors input are very low, efficiency of new product development expenditure is low, single efficiency of innovation input has greatly rising space. There are large regional differences in the efficiency of innovation in China, different province has different advantage of innovation efficiency, China should increase innovation investment. What's more, we should raise theefficiency of R&D funds and manpower input, and reverse "number oriented" of scientific papers and "supply oriented" of patent.
