Abstract
Innovation is the lifeblood of high-tech enterprises to survive and development. In this paper, using DEA model, we analysis three aspects of China's high-tech enterprise independent innovation efficiency of 2004-2011: comprehensive technical efficiency, pure technical efficiency and scale efficiency. The research shows that: in general, the efficiency of independent innovation of China's high-tech industry isn't optimistic, and the comprehensive technical efficiency is not high; relative to the pure technical efficiency, scale efficiency is relatively high, and the vast majority are in the diminishing interval of returns to scale; during the sample period, the decreasing of comprehensive technical efficiency mainly due to the decreasing in the value of scale efficiency.
