The Yangtze River Economic Belt has abundant innovation resources and is a leader in innovation in China. In order to explore the efficiency of technological innovation of its industrial enterprises, this paper measures and analyzes the efficiency of technological innovation of industrial enterprises in the Yangtze River Economic Belt using DEA-Malmquist index method based on the panel data of industrial enterprises in 11 provinces and cities in the Yangtze River Economic Belt from 2011 to 2020. The results show that (1) according to the static DEA analysis, the overall level of technical efficiency of technological innovation of industrial enterprises in the Yangtze River Economic Belt is relatively low during 2011-2020; there are significant differences among the three regions in the upper, middle and lower reaches of the Yangtze River. (2) The dynamic Malmquist index shows that the overall Malmquist index of technological innovation of industrial enterprises in the Yangtze River economic zone during 2011-2020 shows an improving trend, and the main source of its improvement is technological change rather than the efficiency of the utilization of technological innovation factors.
Abstract
The Yangtze River Economic Belt has abundant innovation resources and is a leader in innovation in China. In order to explore the efficiency of technological innovation of its industrial enterprises, this paper measures and analyzes the efficiency of technological innovation of industrial enterprises in the Yangtze River Economic Belt using DEA-Malmquist index method based on the panel data of industrial enterprises in 11 provinces and cities in the Yangtze River Economic Belt from 2011 to 2020. The results show that (1) according to the static DEA analysis, the overall level of technical efficiency of technological innovation of industrial enterprises in the Yangtze River Economic Belt is relatively low during 2011-2020; there are significant differences among the three regions in the upper, middle and lower reaches of the Yangtze River. (2) The dynamic Malmquist index shows that the overall Malmquist index of technological innovation of industrial enterprises in the Yangtze River economic zone during 2011-2020 shows an improving trend, and the main source of its improvement is technological change rather than the efficiency of the utilization of technological innovation factors.
