Under the goal of"double carbon",it is of great significance to analyze the spatial and temporal evolution of industrial eco-efficiency and its influencing factors to achieve industrial green development in Jilin Province.This paper analyses the regional differences,spatial and temporal evolution and influencing factors of industrial eco-efficiency development level in Jilin province based on the panel data of eight prefectural-level cities and province from 2010 to 2021 by comprehensively applying the Super-SBM model of non-expected outputs,Dagum's Gini coefficient and its decomposition,Kernel Density Estimation,and the panel Tobit regression mod-el.The results show that:the development level of industrial eco-efficiency in Jilin Province has large regional differences and shows an increasing trend over time,in which the inter-regional differences are the main source of differences;from the time dimension,the de-velopment level of industrial eco-efficiency in Jilin Province and various regions is unstable and shows a trend of bifurcation,and there are large differences in the level of development of various cities and regions;the degree of influence of factors on the development level of industrial eco-efficiency in Jilin Province varies significantly,which the industrial eco-efficiency development level has a significant influence on the level of industrial eco-efficiency in the province.There are obvious differences in the degree of influence,with indus-trial structure,location entropy,and scientific and technological research and development having a positive effect,while environmental regulations have different degrees of negative influence on the level of industrial eco-efficiency development in Jilin Province.
