Evaluation Of Energy Saving Andenvironmental Expenditure Efficiency And Analysis Of Influencing Factors Among Regions Of China

Since the reform and opening up,China’s social civilization and economic development have made tremendous progress.At the same time,the problem of ecological environment has become increasingly prominent,which has become a short board for building a well-off society in an all-round way.In 2017,the total national expenditure on energy conservation and environmental protection was 561.733 billion yuan,which was 5.64 times that of 2007.According to the China Environmental Bulletin of 2018,more than 60% of the 338 cities at prefecture level and above exceeded the standard in air quality,and 21.7% of them had mild pollution or more days.Despite the increasing investment in environmental protection,the environment in some areas has been improved.However,the objective fact that insufficient investment in environmental protection does not match the needs of environmental protection exists.In the 13 th FiveYear Plan for Eco-environmental Protection,the State Council proposed that the core should be to improve environmental quality,implement the most stringent environmental protection system,and fight three major battles for prevention and control of air,water and soil pollution.In the report of the Nineteenth National Congress of the CPC,it was also pointed out that the strictest ecological environment protection system should be implemented,green development mode and lifestyle should be formed,and harmonious coexistence between man and nature should be maintained.By 2020,the quality of ecological environment will be improved in general,and the level of ecological civilization construction will be in line with the goal of building a well-off society in an all-round way.This paper divides it into four regions: the east,the middle,the West and the northeast,firstly,it summarizes the research status in related fields,explains the concepts of energy saving and environmental protection expenditure and financial expenditure efficiency,and the theoretical basis of environmental protection.Secondly,descriptive statistics are made on the scale and structure of national expenditure on energy conservation and environmental protection,mainly comparing and analyzing the existing emission of environmental pollutants and the effect of environmental treatment in the four regions.Thirdly,based on the historical experience data of the eastern,central,western and northeastern regions,the DEA efficiency evaluation method is used to empirically test the efficiency of energy saving and environmental protection expenditure in the four regions from two perspectives: horizontal(DEA-BCC)and vertical(DEA-Malmquist).From the analysis of DEA-BCC index,from 2007 to 2016,the national average comprehensive technical efficiency value was 0.382,and the eastern,central,western and northeastern areas were 0.438,0.256,0.435 and 0.264,respectively.The expenditure efficiency of energy-saving and environmental protection in the eastern region is superior to that in the other three regions by virtue of its superior economic environment and social development conditions.However,in recent years,the urbanization of the western region has developed rapidly,the ability of environmental governance has increased rapidly,and the expenditure efficiency of energy-saving and environmental protection has been continuously improved.The fact that the regional environmental governance capacity lags still exists,and the overall environmental governance efficiency level is low,which can not achieve the optimal scale utilization efficiency.From the DEA-Malmquist index analysis,the average change of technology progress in different regions is less than 1,which results in less than 1 efficiency value of energy saving and environmental protection expenditure in different regions.Based on the above analysis results,theoretical hypothesis is put forward from four aspects of economic development,urbanization level,scientific and technological progress and environmental protection.The Tobit regression model is used to analyze the influencing factors of energy saving and environmental protection expenditure efficiency.It is found that the efficiency of regional environmental protection expenditure is related to urbanization rate and scientific and technological progress.Finally,according to Tobit’s empirical analysis results and the analysis of the influencing factors of efficiency,some suggestions are put forward to improve the efficiency of energy saving and environmental protection expenditure.
