Research on Innovation Efficiency of Listed Companies in High-end Equipment Manufacturing

Abstract

The development of high-end equipment manufacturing industry is the embodiment of China's comprehensive national strength, and the development of high-end equipment manufacturing industry is inseparable from the improvement of the level of innovation. Through the construction of reasonable innovation input-output index system, based on the Malmquist index method, this paper makes a comprehensive evaluation of the change trend of the innovation efficiency of 22 high-end equipment manufacturing companies from 2012 to 2015, and decomposes the technological progress and technological efficiency change. Results show that: (1) There is a serious phenomenon of redundancy in the entrepreneurial activities of high-end equipment manufacturing enterprises. (2) From 2012 to 2015 years, the overall innovation efficiency of China's high-end equipment manufacturing enterprises are in the promotion, but the index of technological progress is on the decline, and the technical efficiency change index of ascension is the main reason for the current innovation to improve the efficiency of our country.
