Analysis on the coupling coordination recationship and driving force between technological innovation and carbon emission efficiency in the Yangtze River Economic Belt
Based on the data of 11 provinces and cities in the Yangtze River Economic Belt from 2011 to 2021,this paper uses entropy weight method and SBM-Malmquist index to measure the technological innovation level and carbon emission efficiency,and analyzes the coupling coordination relationship and influencing factors between technological innovation and carbon emission efficiency.The findings are as follows:First,the technological innovation level in the Yangtze River Economic Belt is on the rise,and the carbon emission efficiency values remain basically stable after fluctuations.There are significant differences in the technological innovation level and carbon emission efficiency values in the upper,middle and lower reaches,showing a"V-shaped"distribution.Second,the coupling degree between technological innovation and carbon emission efficiency in the Yangtze River Economic Belt experienced three stages:antagonism,coupling and run-in.The coupling coordination degree enters the moderate coordination stage.Third,environmental regulation,education level and tertiary industry structure level are important factors to improve the coupling coordination level between technological innovation and carbon emission efficiency.Urbanization level and opening to the outside world have significantly different impacts on the upper,middle and downstream coupling coordination.
