Research on the Measurement of Technological Innovation Efficiency and its Influencing Factors in the Chengdu-Chongqing Economic Zone

Abstract

This article constructs an evaluation index system for technological innovation efficiency. Using panel data from 16 cities at the prefecture level and above in the Chengdu-Chongqing Economic Zone from 2013 to 2019, the DEA-BCC model is employed to statically measure the technological innovation efficiency in the region. The Malmquist index method is used to conduct a dynamic analysis of the technological innovation efficiency, and the Tobit regression analysis method is applied with the comprehensive efficiency obtained from the BCC model results as the dependent variable to explore it’s influencing factors. The study reveals that there are significant differences in the comprehensive efficiency of technological innovation among cities in the Chengdu-Chongqing Economic Zone, with an overall value of 0.818. The slow development of technological innovation in some areas is mainly due to the mismatch between input and output in technological innovation. The intensity of government support and the degree of openness to the outside world has a significant impact on technological innovation efficiency in the Chengdu-Chongqing Economic Zone, while the influence of industrial structure and infrastructure level is not significant.
