Research on Innovation Efficiency of Hubei High-tech Industry Based on DEA and PSM-DID Models

Abstract

This paper uses the DEA-Malmquist model to study the efficiency and changes of the overall technological innovation activities of high-tech industries in Hubei Province from 2010 to 2016, and finds that the total factor productivity of Hubei Province has declined slightly in recent years, and the efficiency of overall technological innovation activities is low, which can be manifested as weak growth of technical efficiency and technological progress level and weak stability. In addition, this article uses the "Wuhan Independent Innovation Capability Enhancement Plan (2013-2016)" to express government support, and uses 60 listed companies in Hubei Province as a sample and uses the PSM-DID model to investigate the effect of government support on the efficiency of corporate innovation, to further verify the above conclusions. The verification results show that the innovation-driven policies of Hubei Province have no significant positive effect on the innovation efficiency of high-tech enterprises.
