| Since the reform and opening up,China has achieved rapid economic development with extensive development mode,but with the rapid increase of carbon dioxide and other greenhouse gas emissions.At present,the new development concepts of "economic new normal","supply-side structural reform" and "innovation,coordination,green,open and Shared" are put forward.All these measures indicate that China’s economy will develop in an intensive and sustainable direction.At the same time,it is also the most effective way to reduce carbon emission intensity.The Chinese government has made a carbon emission reduction commitment to the world that "China’s carbon emission intensity will be reduced by 40%~50%by 2020".Therefore,this paper explores how to accelerate the process of China’s carbon emission reduction task with the "financial hand" and realize the transformation from high-carbon economy to low-carbon economy under the concept of sustainable developmentFirst of all,this article from the relationship between financial development and carbon emissions,mechanism study and empirical analysis of the three angles of combing the domestic and foreign research literature,found that more than existing literature from two aspects of technical effect and structural effect research of the relationship between financial development and carbon emissions,and choose a single,financial development index is difficult to objectively describe the actual financial development present situation,for this,this paper puts forward a new research idea,namely inherited predecessors’ from two aspects of technology and the structure and combining with China’s actual conditions to analyze the relationship between financial development and carbon emissions and mechanism,and from two aspects of input and output through building index system of financial development,It is more in line with China’s actual financial development,and the spatial econometric model considering geographical and spatial location factors is used to test the relationship between financial development and carbon emissionsSecondly,the paper analyzes the current situation of financial development efficiency and carbon emission at the provincial level in China.First of all,this paper constructs the input index of financial development from four aspects:banking,insurance,securities and financial environment,and selects the added value of financial industry as the output index of financial development.The entropy method and stochastic frontier model are used to calculate the financial development efficiency of provinces and regions in China.According to these indicators,the development status and efficiency of China’s banking,insurance,securities,financial environment and financial added value are analyzed;Second,of standard coal in the IPCC method,this paper calculates the carbon intensity of China’s provinces domain,the calculated result shows that our country as a whole,and even the things in the three areas of the average carbon intensity declining trend year by year,but the provincial perspective,China’s southeast coastal developed provinces of carbon emissions intensity is relatively low,and the backward economy in the western region carbon emissions intensity is relatively high;Third,through comparative analysis of financial development efficiency and carbon emission intensity in China’s provinces,the paper draws a qualitative conclusion that regions with higher financial development efficiency have lower carbon emission intensityThen,on the basis of the above analysis,this paper constructs the spatial error model(SEM)and spatial lag model(SLM)based on the STIRPAT model.According to the technical effect and structural effect in the theoretical analysis,technological progress index and Moore industrial structure upgrade index are selected as the core variables in this paper,and the four indicators including openness,contribution of external funds,government intervention and environmental regulation are selected as the control variables.The empirical test results show that there is an inverted u-shaped curve between financial development efficiency and carbon emission intensity,and financial development efficiency can reduce the carbon emission intensity of provinces through technological progress and industrial structure upgradingFinally,according to the empirical study can be concluded that carbon spatial distribution characteristics,the relationship between financial development efficiency and carbon emissions space effect and efficiency of financial development on carbon emissions spillover effect the conclusion of these three aspects,and system design,from the top of the carbon reduction efficiency of financial development to promote the ability of technology innovation,financial development efficiency,promote industrial upgrading process of these three aspects put forward relevant policy Suggestions. |
