| After the reform and opening up,China’s economic operation capacity has been significantly improved,but due to the traditional extensive economic development model,the deterioration of China’s environment has been exacerbated.Moreover,China is currently in a period of economic transformation and upgrading,and its economy and society has entered a stage of medium-to-high-speed economic development,which has caused my country to fall into the dual dilemma of environmental degradation and economic and social decline.The report of the 19 th National Congress of the Communist Party of China emphasizes the strategic position of ecological civilization construction,which provides theoretical guidance for optimizing the quality of my country’s ecological environment and further promoting healthy economic and social development.In the context of the "30·60" dual-carbon goal,the 2021 government work report proposes that the implementation of a special policy of financial support for green and low-carbon development,and green financial services will be the main focus of future policies.Green finance pays more attention to environmental factors,and regional ecological efficiency emphasizes the coordinated development of the economy,society and the natural environment.Therefore,studying how to use green financial development to improve regional ecological efficiency is conducive to solving the current dual dilemmas faced by my country,and is conducive to the implementation of the national ecological civilization construction.Strategy is important.In view of this,this paper first summarizes the relevant economic theories,and the key contents include the environmental Kuznets curve theory,the environmental resource price theory,the resource optimization selection theory,and the sustainable development theory.And based on the function of green finance,the mechanism of the development of green finance on regional ecological efficiency is discussed;secondly,the paper constructs the evaluation index system of green finance and regional ecological efficiency,and uses the entropy method and the Super-SBM model including unexpected results to measure the development level and regional ecological efficiency of green finance in my country in from 2009 to 2020;then choose the spatial Durbin model to analyze the impact and spillover effect of green finance development on regional ecological efficiency,and further study the regional heterogeneity;then,verify the two mechanisms through the intermediary effect;finally,based on the empirical results and according to the current national conditions,policy recommendations are made.The conclusions of this paper are as follows:(1)From the perspective of time dimension,the overall level of green finance development in China is steadily rising,and the regional ecological efficiency shows a trend of first decreasing slightly and then rising;from the perspective of spatial distribution pattern,the development level of green finance and the regional ecological The distribution pattern of "high in the east and low in the central and western regions" is shown in the eastern region,and the eastern region is significantly higher than the central and western regions,and the difference between the central and western regions is not significant.(2)The empirical results show that the relationship between the development level of green finance and the regional eco-efficiency is a“U”-shaped relationship that suppresses and then promotes.At present,the “technical progress” effect of my country’s green finance on regional eco-efficiency is smaller than the “capital scale” effect.,in the first half of the "U"-shaped curve,and there is a "U"-shaped spatial spillover effect,and the impact of green finance on the ecological efficiency of the eastern,central and western regions shows significant heterogeneity.By examining the mediating effect of capital scale and technological progress,the "technical progress" effect and "capital scale" effect of green finance on regional ecological efficiency are verified.(3)The article puts forward specific policy suggestions from the perspectives of promoting the development of green finance diversified products,realizing the coordinated development of green finance regions,and promoting scientific and technological progress. |
