Analysis Of Regional Environmental Efficiency Measurement And Influencing Factors In China

Due to the acceleration of China's industrialization process and rapid economic growth,it can be clearly seen that the problem of urbanization has been improved.However,under this development model,a series of environmental problems,such as ecological imbalances,low utilization of natural resources,declining environmental quality,and increasing environmental health losses,are also caused.Today,all walks of life are increasingly aware that environmental issues have increasingly threatened the survival and development of human beings.Therefore,under this premise,it is possible to establish a calculation system that accurately measures environmental efficiency,and the need to find an impact factor that plays a major role in environmental efficiency is becoming more and more urgent.In order to measure China's environmental efficiency and study its influencing factors,this paper innovatively adopts a three-stage DEA method to accurately measure the effects of eliminating environmental factors and random disturbances.In the total of 10 years from 2008 to 2017,30 provinces in China The actual environmental efficiency and its changing trends in the municipal,autonomous,and three regions are compared with the efficiency results calculated by the traditional DEA model.Moreover,using the Bootstrap-DEA method and the Tobit model,regression equations are established to determine the internal and external factors that affect the environmental efficiency,and the results are used for size comparison and depth analysis.Through the investigation of the true measurement and influencing factors of environmental efficiency,we can find that after eliminating the influence of environmental factors and random errors,the real environmental efficiency values of each province are lower than the environmental efficiency values measured by traditional methods,and the pure technical efficiency.The impact of scale efficiency on environmental efficiency is greater.There is a clear imbalance between the regions.The eastern region has the highest efficiency value,the western region is second,and the central region is the last.For the influencing factors,the level of fiscal expenditure and the degree of openness will reduce the environmental efficiency value;while the urbanization rate and the increase in industrial sales value above designated size will increase the environmental efficiency.Therefore,the corresponding policy recommendations are drawn to improve the ecological environment,promote green development,build social civilization,and fundamentally improve the level of environmental efficiency.
