| Promoting the optimization and upgrading of regional industrial structure is not only an inherent requirement for realizing the goal of "double carbon",but also an important driving force for achieving high-quality economic development.In recent years,green finance has played an increasingly prominent role in promoting the optimization and transformation of industrial structure.By incorporating environmental benefits into daily financial services,green finance can guide green funds to the environmental protection industry and enhance the green technology innovation ability of enterprises,thus promoting the transformation and upgrading of traditional industries and the rapid development of emerging environmental protection industries.Since June2017,China has set Guangdong,Zhejiang,Jiangxi,Guizhou,Xinjiang,Gansu and Chongqing as green finance reform and innovation pilot zones in three batches.Since then,the construction of green finance in China has begun to enter the practical stage.Each pilot zone explores the development mode of green finance "pilot field" with its own characteristics based on its location conditions and industrial base.The move aims to rationally allocate credit resources,guide funds to green projects,increase the financing constraints on heavily polluting enterprises,and force the "top two" enterprises to develop green technologies and optimize internal production processes to achieve transformation and upgrading.At present,the optimization of industrial structure is an urgent problem to be solved to achieve high-quality development.Scientifically measuring and evaluating the policy effect of green gold reform pilot zone on industrial structure adjustment has an important guiding role in further optimizing industrial structure and achieving high-quality development.In the empirical research part,the green finance "pilot field" policy implemented in 2017 is regarded as a quasi-natural experiment,and the influence of setting up green finance reform and innovation pilot zone on industrial structure upgrading,rationalization and ecologicalization is tested empirically with the method of differential analysis.This paper uses theoretical analysis and empirical test to discuss the specific impact of green finance reform and innovation pilot zone policies on regional industrial structure optimization.In the theoretical research part,the paper analyzes the influence of the green gold reform pilot zone policy on the optimization of industrial structure by influencing the differentiated capital formation of high energy consumption industries and green industries,transmitting the signal of developing green economy and guiding the enterprise public,promoting industrial integration and achieving scale effect,improving the micro-level credit resource allocation efficiency,encouraging technological innovation and other mechanisms.The results show that the establishment of green finance "experimental field" can significantly affect the regional industrial structure of the high level and ecological,this conclusion is still robust after passing the parallel trend test and placebo test.However,it did not promote the development of industrial structure towards a more reasonable direction in the short term.Further research shows that the pilot policy of green finance reform and innovation pilot zone has more significant effect on the industrial structure of central and western cities.Of the old industrial base the city’s industrial structure and the industrial structure of the old industrial base city for empirically ecological impact is more significant.Finally combining the empirical analysis result,and puts forward the policy Suggestions on the five aspects. |
