Study on Influence Factors of Technology Innovation Efficiency in China's Manufacturing Industry

Based on the approach of Stochastic Frontier Analysis and adopting the model of Trans-long Production Function, using the panel data of 25 manufacturing industries from 2009 to 2015 in China, this paper measures the technology innovation efficiency and analyzes influence factors of domestic enterprises. The results show that there is technological innovation inefficiency in domestic enterprises of manufacturing during 2009 to 2015. In terms of the factors that influence technology innovation efficiency, enterprise scale, market structure, technology acquisition and retrofit costs have positive effects on technology innovation efficiency, while export-oriented degree have negative and profitability has no significant effect on technological efficiency.
