A Study On The Effect Of Land Finance And Urbanization To Green Economic Efficiency

At present,under the background of China's rapid economic development,resources and environmental issues have become increasingly prominent,and it has become the main resistance to China's transformation of green sustainable economic development.In current day and ages,it can be seen that improving the green economic efficiency has become an important issue in sustainable development.The green economic efficiency is different from the traditional economic efficiency because the calculation of green economic efficiency considers the undesired output like pollution emissions.Thus,the green economic efficiency is a comprehensive measurement to reflect the level of green development better.On the other hand,since the new century,China's land finance scale has expanded rapidly and the urbanization has also increased rapidly,which has become an important part of economic development.So how the development of land finance and urbanization will affect the efficiency of green economy has become the focus of this paper.Therefore,this paper integrates land finance and urbanization into the same framework to study the impact of land finance and urbanization on the green economic efficiency.Firstly,this paper discusses the definition of the related concept and theoretical analysis of the impact mechanism of land finance and urbanization on the green economic efficiency.Then,by constructing the index system and using the super-efficient data envelopment analysis slack-based measure model(DEA-SBM)to calculate the green economic efficiency in China.And analyze the status quo of land finance and urbanization in China.Finally,on the basis of theoretical mechanism and status quo analysis above,this paper uses the spatial autoregressive model to empirically analyze the impact of land finance,urbanization and related control variables on green economic efficiency.And the results show that both land finance and urbanization can positively affect the green economic efficiency through the corresponding path,and green economic efficiency has a spatial aggregation effect.In addition,the regression results of sub-regional show that the coefficients of key variables are decreasing between the east,middle and west region.On the other hand,the impact of the spatial spillover effect of land finance and urbanization on green economic efficiency also exists.Finally,the regression results also show that the control variables including the industrialization,human capital,technological development,economic development and innovation have varying degrees of impacton green economic efficiency.
