Research On Regional Differences And Influencing Factors Of Ecological Welfare Performance In China

In December 2021,the Sixth Plenary Session of the 19 th Central Committee of the Communist Party of China pointed out that the construction of ecological civilization is the most important foundation for sustainable development,a prerequisite for economic development,and an important guarantee for improving people.Coordinating the relationship between the economy,the environment and social welfare is still an important topic of current research,and it is also an inherent requirement to the concept of high-quality development.If a coordination point can be found between the investment of resources,the development of the economy and welfare,it will help country achieve sustainable development.Ecological welfare performance,as a measurement index reflecting the improvement of welfare level under a certain level of natural resource consumption,meets the needs of "environment-economywelfare" coupling and synergy.Therefore,measuring sustainable development level with the level of ecological welfare performance and exploring the key factors will help to achieve a "win-win" situation of ecological environmental protection,economic growth and social welfare enhancement,and then comprehensively promote China’s Coordinated and high-level development of the socio-economic-ecological complex system.This paper sorts out the relevant literature on ecological welfare performance around the measurement system,measurement method,and influencing factors;combines the concept of sustainable development,ecological economics and basic theories of welfare economics,defines the connotation of ecological welfare performance,and builds ecological welfare performance on this basis.Welfare performance measurement system.Secondly,the ecological welfare performance of 30 provinces and three major regions in country was measured by the combination of the entropy weight method and the Super-SBM model.The difference of ecological welfare performance is analyzed,and then the convergence trend of ecological welfare performance difference is judged based on the σ-convergence and absolute β-convergence models.Finally,with ecological welfare performance as the explained variable and factors such as industrial structure,economic scale and population agglomeration as the core explanatory variables,the Tobit regression model is used to investigate the influence mechanism and degree of influence of each factor.The results show that: From 2011 to 2020,country’s ecological welfare performance showed an "inverted U-shaped" trend,which was still in an insufficient stage.From a national perspective,the ecological welfare performance of country’s 15 provinces was in the High efficiency level;from the regional level,the overall ecological welfare performance presents a pattern of "strong in the east,weak in the middle and weak in the west".Secondly,although the difference in ecological welfare performance is shrinking,it is still in an unbalanced stage.From the perspective of absolute differences,the multi-polar distribution pattern is the mainstream trend of ecological welfare performance;from the perspective of relative differences,regional differences are the cause of the overall the main reason for the balanced distribution;from the perspective of differential convergence,the ecological welfare performance of various regions in my country has σ convergence at different stages.Except for the eastern region,all other regions have absolute β convergence,and the differences sometimes expand and the convergence speed varies.First,my country’s ecological welfare performance has not reached a stable situation.In addition,ecological welfare performance is positively affected by economic scale,technological innovation and environmental regulation,while industrial structure,as a negative factor,has an inhibitory effect on the improvement of ecological welfare performance.Based on this,this paper puts forward the following suggestions: The first is to achieve high efficiency of ecological welfare performance through the win-win situation of“economic growth,environmental improvement and welfare enhancement”;the second is to achieve balanced development of ecological welfare performance through coordinated strategies;the third is to promote efficiency improvement through industrial optimization strategies;the fourth is to use technology The innovation pattern will steadily improve efficiency;fifth,comprehensive environmental regulation tools will help improve efficiency.
