Reduction effect of carbon emission and optimisation path of green finance

Under the background of "dual-carbon",green finance is an important way to promote carbon emission reduction and realize the development of a low-carbon economy.Using provincial panel data from 2000 to 2020,this paper constructs a basic regression model to study the "carbon reduction " effect,mechanism of action,and heterogeneity of green finance.The study finds that:the development of green finance significantly inhibits carbon emissions and has an obvious "carbon reduction " effect;green technology innovation has a mediating effect on the carbon emission reduction effect of green finance;in regions with a high level of economic development or a high degree of marketization,the "carbon reduction " effect of green finance is significant.
