Study On The Coupling And Coordination Of Green Economy And Financial Development In The Yangtze River Delta Urban Agglomeration

At present,China’s economy has entered the track of high-quality development,people’s income has been continuously improved,industrial development has continued to improve,and the international status has been increasingly improved.However,the extensive economic development in the past has caused a series of problems such as resource and energy shortage,ecological environment deterioration,and prominent human-land conflicts.The green economic development model,as an extension of the concept of sustainable development,is an inevitable choice to coordinate the relationship between economy,society and environment.As the core of modern economy,finance is crucial to promote industrial transformation and upgrading and promote green and low-carbon economic development.As the frontier highland of national economic development and financial agglomeration,the Yangtze River Delta urban agglomeration explores the coupling and coordination relationship between finance and green economic development,integrates finance into the process of green economic development,and promotes the synergy between the two,which is of great significance for realizing the sustainable development of finance and economy in the Yangtze River Delta region and even the whole country.Based on this,this paper,by combing the existing literature,and on the basis of understanding the relevant theoretical concepts of green economy and financial development,the mechanism of their coordination and analysis of the current development situation,respectively constructs the evaluation index system of green economy and financial development of the Yangtze River Delta urban agglomeration,and measures its green economy and financial development level between 2015 and 2020 using CRITIC-Mahalanobis distance TOPSIS method,Then,the coupling coordination relationship between the two systems is studied through the coupling coordination degree model.Finally,the key obstacles hindering the green economy and financial development of the Yangtze River Delta urban agglomeration are identified through the obstacle degree model.The research shows that:(1)The overall level of green economy and financial development of the Yangtze River Delta urban agglomeration has a steady upward trend from 2015 to 2020,and the level difference between different cities is significant.The comprehensive performance is as follows: Shanghai>Jiangsu>Zhejiang>Anhui;In terms of green economic development,Shanghai,Nanjing and Hangzhou have the leading comprehensive level,and Xuancheng,Chizhou and Tongling have the lowest ranking.On the four standard levels of green economic development,the environmental protection level has the highest score over the years;In terms of the level of financial development,Shanghai,Nanjing,Hangzhou,Suzhou and Hefei are in the leading position,while Chuzhou,Xuancheng,Anqing,Chizhou and Ma’anshan are ranked lower.On the three standard levels of the financial development system,the score of the financial scale level is increasing year by year,and the score of the financial structure level is the highest over the years.(2)During the study period,the coupling effect of green economy and financial development in the Yangtze River Delta urban agglomeration was significant,the coupling coordination degree showed a wave-like upward trend,and the overall level fluctuated between the barely coordinated level and the primary coordinated level;In terms of city level,Shanghai,Nanjing,Hangzhou,Suzhou and Wuxi are in the leading position in terms of coupling and coordination,while Chuzhou,Xuancheng,Chizhou,Tongling and Maanshan are lagging behind and in a state of unbalanced development;The spatial distribution is characterized by unbalanced distribution,and the coordination level is uneven,which shows that the eastern coastal cities are high,the southwest inland cities are low,and Shanghai,Nanjing,Hangzhou,and Hefei are the point centers and gradually decline to the four sides.(3)The empirical results of the barrier model show that water saving,the comprehensive utilization of general industrial solid waste,the proportion of the output value of the tertiary industry,the number of public toilets per10000 people,and the proportion of the industrial output value are the main obstacles to the development of the green economy in the Yangtze River Delta urban agglomeration,while the deposit and loan ratio of financial institutions,the deposit and loan balance of financial institutions,and the insurance depth are the main obstacles to the financial development level of the Yangtze River Delta urban agglomeration.Based on research findings,this article proposes that(1)cities should prioritize both local adaptation and coordinated development;(2)Improve the energy regulatory system and strengthen energy-saving publicity to promote green production and life;(3)Optimize the financial ecological environment and vigorously develop green finance to improve the efficiency of financial services.A total of three countermeasures and suggestions are proposed to promote the coordinated development of green economy and finance in the Yangtze River Delta urban agglomeration.
