| To address global climate change,promote climate governance and draw up a blueprint for sustainable development,countries around the world are paying more attention to environmental protection than ever before.Green finance,as an important means to coordinate economic development and environmental governance as well as accelerate China’s environmental protection process,has gained attention and gradually developed in China in recent years.However,the coupling and coordinated development level between green finance and environmental protection system in China has not been explored.Base on the interlinked and consistent of "coupling" and "symbiosis" in the ecological economic system,to study the symbiosis of relevant participants is to further expand and improve the research on system coupling.Therefore,financial institutions and the environmental protection enterprise as the most important main body in the process of green environmental protection,their symbiosis model under the background of the green financial and environmental protection system coupling needs to be further exploration,to explore more helpful tripartite cooperation policy path to improve the coupling and coordinated level of green finance and environmental protection system.This study measures the coupling and coordinated level of green financeenvironmental protection system(GE system)in 30 provinces of China from 2011 to2020,and uses the improved GM(1,1)model based on background value optimization to predict the future development trend of the coupling and coordinated level of green finance-environmental protection system.Based on the coupling research results,further explore the symbiosis model of government departments,financial institutions and environmental protection enterprises.Combining with the financial symbiosis theory,a three-party game model is constructed.With the help of numerical simulation experiments,this paper discusses the dynamic game process and symbiosis strategy profile of green finance-environmental protection system’s relevant participating subjects in green environmental protection,so as to study the coupling development of green finance and environmental protection system comprehensively.Finally,based on the empirical and simulation results,the countermeasures and paths are designed to improve the coupling and coordinated development level of green financeenvironmental protection system,and then help realize the "dual carbon" strategic goal.The specific research results are as follows:(1)The national average coupling and coordinated level of green finance-environmental protection system has been in mild disharmony from 2011 to 2020 all the time,and only Guangdong Province and Zhejiang Province among them have reached the coordination level.(2)The coupling and coordinated level of green finance-environmental protection system based on regional difference has a large gap,ranking in order: Eastern region> Central region >Western region > Northeast region.(3)The national average coupling and coordinated level will reach the coordination level in 2077,which fails to get ahead of “2060carbon neutrality” goal.(4)Under the current Chinese green finance and environmental protection reward and punishment policies,the tripartite evolution stability strategy is(highly intervention,active cooperation,speculative development and construction).In other words,when the government highly interferes and financial institutions actively cooperate,environmental protection enterprises appear "freeriding" behavior in decision-making.(5)The simulation results of evolution under different arrays show that increasing the probability of deregulation by government departments is helpful to promote environmental protection enterprises to adopt standardized development and construction strategy and financial institutions to select active cooperation strategy,so as to achieve the purpose of regulation.According to the above research and analysis,this paper puts forward the targeted specific policy proposals,aiming to narrow regional gap and improve the national coupling and coordinated level of green finance and environmental protection system and improve the tripartite game’s overall efficiency of government departments,financial institutions and environmental protection enterprise,so as to help accelerate the process of implementing green development in China.Figure [11] Table [9] Reference [74]... |
