Research on the Evaluation of Green Development Efficiency of Zhejiang Province Industry under the Background of ‘Dual-carbon’

This paper collects data from 11 prefectural-level cities in Zhejiang Province from 2011 to 2020, and measures the industrial green development efficiency of each prefectural-level city in Zhejiang Province using the global Super-SBM model based on non-expected output combined with the GML index. The results show that, from a static point of view, from 2011 to 2020, the industrial green development efficiency of Zhejiang Province is still in the middle-low level, but there is an imbalance in the development of each prefecture-level city. From the dynamic point of view, except for Jinhua, the GML index is less than 1, the GML index of all the other cities is greater than 1, which indicates that the industrial green development efficiency of all the cities except Jinhua is improving, in addition, the improvement of industrial green development efficiency in Huzhou and Taizhou is the change of technical efficiency, while the improvement of industrial green development efficiency of the rest of the cities mainly depends on the technological progress.
