| Under the background of my country’s "dual carbon" strategy,whether green finance can promote technological innovation has become the main focus of attention.This paper uses the data of cities in the three major economic circles from 2015 to 2020 to investigate whether green finance can promote the efficiency of urban technological innovation and whether environmental regulation can regulate it.In recent years,energy conservation and environmental protection have attracted widespread attention from all sectors of society.How to achieve sustainable development is an important issue that the entire society must consider.At the beginning of the 21 st century,my country’s technological innovation level is constantly improving,and green finance has also developed rapidly.However,the degree of green financial development and the efficiency of technological innovation in various cities in China are significantly different.How to build a matching green financial system and promote technological innovation has become a thorny problem for local governments to solve.To grasp it,it needs continuous practice and exploration.This thesis adopts the research method of combining two ways to study the urban technology response of green finance and consider the regulating role of environmental regulation in it.Green finance and environmental regulation are analyzed.How does the interaction between green finance and environmental regulation affect the efficiency of urban technological innovation? Since green finance and environmental regulation have both a positive promotion and a negative hindrance transmission mechanism for urban technological innovation efficiency,the urban technological effect of green finance under environmental regulation is uncertain.In terms of empirical analysis,use the entropy method and coupling coordination degree to build green financial indicators,use the number of laws and normative documents to measure environmental regulation,and then use data envelopment analysis(DEA)to measure the efficiency of urban technological innovation after removing environmental factors,in order to study the relationship between green finance,environmental regulation and urban technological innovation efficiency in China’s three major economic circle urban agglomerations from 2015 to 2020.At last,the paper analyzes the influence of green finance and environmental regulation on urban technological innovation in the three economic circles.It is found that green finance significantly promotes urban technological innovation in the three economic circles,but after the introduction of green regulation and green finance multiplication,environmental regulation has a negative correlation with the regulation of green finance and urban technological innovation. |
