| Since the reform and opening up,the level of industrialization and urbanization in my country has been continuously improved,and the economy and society have developed by leaps and bounds.At the same time,my country’s total energy consumption has increased year by year.However,my country’s energy efficiency has been too low for a long time,which wastes precious energy resources,and is not conducive to the coordinated and sustainable development of the economy and society.Therefore,under the background of the current dual-carbon policy,optimizing the industrial structure,reducing the proportion of high-energy-consuming industries,further improving energy efficiency,and solving the problem of excessive energy efficiency gaps between regions are the issues that the country and society will continue to focus on in the future.With the launch of the State Council’s green finance pilot project and the introduction of green finance policies,my country’s green finance development level has been greatly improved,and my country’s total energy consumption,energy efficiency,and energy structure have also been greatly improved,while further improving environmental quality.It has been improved to a certain extent,which is conducive to the sustainable and healthy development of the energy,environment and economy.This thesis first introduces the concept of green finance and the development process of green finance,then introduces the concept of energy efficiency,the influencing factors and index evaluation of energy efficiency,and analyzes the transmission mechanism of green finance policy on energy efficiency.Secondly,it introduces the current situation of my country’s total energy consumption,energy consumption structure,and energy intensity,and selects appropriate input-output indicators.Considering environmental factors and random factors,the SBM-DEA model is used to calculate the total energy consumption considering undesired output.Factor energy efficiency.At the same time,based on the panel data of 30 provincial administrative regions in my country from 2010 to 2019,the double difference method is used to study the policy effect of green finance on energy efficiency,and it is concluded that the green finance policy has effectively improved the energy efficiency of the pilot provinces.Using PSM-DID test,placebo test,time point of changing policy,changing control group and time span of various robustness tests all show that the conclusion has strong reliability.Then,the policy impact of green finance on energy efficiency is further studied through heterogeneity test and dynamic effect test.It is concluded that the role of the eastern region in the implementation of green financial policies is obvious,the role of the central and western regions in the implementation of green financial policies is slightly weaker,and the provinces with lower energy efficiency have a weaker role in the implementation of green policies.The marginal effect of financial policy on promoting energy efficiency is gradually increasing.Finally,through the intermediary effect test,it is concluded that green finance pilot policies can affect energy efficiency through the intermediary effect of technological innovation,and there is a positive indirect impact,while the transmission mechanism of green finance affecting energy efficiency by acting on the upgrading of industrial structure is not ideal.Through the analysis of the empirical results and the reliability conclusions drawn from the analysis,in order to give full play to the policy implementation effect of green finance in the energy field,effectively improve energy efficiency,improve energy structure,comprehensively promote green finance policy,and further contribute to my country’s To successfully achieve the dual carbon goal,we will provide corresponding feasible suggestions. |
