| With the development of the times,people are pursuing economic growth and improving the quality of life.They are also committed to building a good natural ecological environment.Realizing the coordinated development of finance and the environment is the only way to promote the current sustainable development of the economy and society.On the one hand,in the process of global economic integration,various regions have gradually formed a financial agglomeration model and developed into a financial center,which has a certain driving influence on the regional financial development and the surrounding regional economy.On the other hand,the environment on which we live has been severely damaged.Natural disasters such as global warming,sea level rise,and severe haze are caused by human actions such as excessive felling of trees,inappropriate garbage disposal,and the emission of harmful fumes and wastewater.In order to achieve both economic growth and environmental improvement,people strive to allocate financial resources in the direction of green development,and green finance has become the focus of economic research.Based on this,the research on the relationship between financial agglomeration,green finance and ecological environment has important theoretical and practical value.Studying the coupling and coordinated development of financial agglomeration,green finance and the ecological environment is of great significance for promoting economic development and improving the ecological environment.This article takes the eastern provinces of China as the research object,combines the construction principles of the evaluation index system,uses the projection pursuit method to measure the comprehensive index values of the three subsystems,and quantitatively analyzes the coupling coordination degree of the ternary system through the coupling degree and coupling coordination degree model.This study studies the coupling between the three subsystems of regional financial agglomeration,green finance and ecological environment,and makes suggestions for future regional economic development and environmental protection.The research data in this article are all derived from the "China Statistical Yearbook","China Environmental Statistics Yearbook" and the provincial and municipal statistical yearbooks,"China Financial Yearbook","China Regional Financial Operation Report",Wind database and EPS database.Through empirical research on the coupling model,this paper draws the following four research conclusions.First,the provincial financial agglomeration,green finance and eco-environment system in the eastern part of China are in a high-level coupling stage,and high coordination standards have been achieved between regions.Beijing,Tianjin and Hebei have reached high-quality coordination standards in recent years,and the degree of mutual influence between subsystems is relatively high,financial agglomeration,green finance and ecological environment develop together.Although the ternary system has reached a good coupling state,there are still many problems in the regional economic development and environmental governance,and further development planning is still required.Second,the degree of financial agglomeration in eastern provinces and cities in China is deepening year by year,and the degree of financial agglomeration in Hebei Province is weak,which belongs to the development type of lagging financial agglomeration.It is also necessary to increase the degree of financial agglomeration to improve the overall level of coupling of the system.Third,the overall development of green finance in China has an upward trend.The comprehensive index value of green finance in Beijing,Shanghai and other provinces and cities reached a peak in 2017,but the region is lagging behind the development of green finance,it shows that compared with the economic development level of economically developed regions,green finance still has a lot of room for improvement.Fourth,the ecological environment in the eastern provinces of my country is relatively stable.The three provinces of Zhejiang,Jiangsu,and Shandong are slightly behind and lagging behind in the development of the ecological environment.The ecological environmental protection of these areas needs to be focused on.The innovation of this article is as follows:The first is the research perspective of this article.In the current context,scholars at home and abroad have conducted in-depth and extensive research on financial agglomeration,green finance and regional ecological environment,and there is no research on the coupling and coordination between the three.This article uses this as an entry point to discover the mutual promotion mechanism between regional financial development and environmental protection through a coupled model.The second is the construction of the evaluation index system.Combining the actual situation and the understanding of the existing research results,this paper establishes an index evaluation system for financial agglomeration,green finance and ecological environment,in order to measure the comprehensive index value of the three subsystems.In the green financial subsystem,the evaluation index system is constructed from the three aspects of green securities,green insurance and green investment;in the ecological environment subsystem,the proportion of natural reserves in the jurisdiction area is added as an indicator,which rarely appears in other scholars’ articles.The possible shortcoming of this article is as follows:the development of green finance in China is still in its infancy,and it is difficult to obtain relevant data,which limits the research on the coupling and coordination between financial agglomeration,green finance and the ecological environment in this article.Related issues need to be further studied and discuss.
