环境约束下中国省际水资源两阶段效率及影响因素研究
Two-stage utilization efficiency of the interprovincial water resources under environmental constraint and its influence factors in China
摘要
Abstract
Water resource utilization system can be divided into water resource utilization and pollution processing subsystem.This paper proposes a considering the undesirable output SBM efficiency evaluation model under environmental regulation based on the slack two-stage model.Taking advantage of the input and output data of 31 provincial administrative region in China from 2001 to 2014,considering regional two-stage water resources utilization process,the overall China's regional water resource utilization efficiency and each stage efficiency are measured.And the space-time characteristics of the overall efficiency of the regional water resource utilization in China are analyzed with the spatial autocorrelation analysis method.We employ spatial lag and spatial error econometric model under considering spatial effect and analyzing the influence factors of the overall efficiency of water resources utilization from the per capita water resources,industrial water,living water consumption,per capita GDP,the degree of opening to the outside world,the industrial structure,technological progress and other aspects.The results shows that:① From an overall perspective,the first stage efficiency is significantly higher than the second phase water resources utilization efficiency,and the overall efficiency is close to the second stage efficiency,the second stage efficiency determines the overall effectiveness of the water resources utilization.② Through each stage slack of input and output,the problems of excessive output of water pollutants and poor handling water pollutants are the cause for the low second the second stage efficiency.③ The spatial autocorrelation intensity of overall efficiency of water resources utilization is significantly greater than zero,and overall efficiency of water resources utilization presents the characteristic of concentration distribution in the space;the eastern coastal region has concentration of H-H type,and the central and western regions of L-L type.④ The overall efficiency of water resources utilization has spatial spillover effects,and a region's overall efficiency is not only affected by regional factors,but also affected by heighbouring overall efficiency.⑤ Through spatial econometric models,the results show that industrial water consumption has a significantly negative impact on overall efficiency of water resources utilization,and per capita GDP as well as the degree of opening to the outside world have a significantly positive impact on overall efficiency of water resources utilization in China.According to the above empirical results,the conclusions as following:First,strengthening water pollutants discharge management,and enhancing the capacity of sewage treatment.Second,achieving industrial water with high efficiency and reducing industrial water consumption.Third,giving full play to advantages of regional water resources endowment,strengthening regional cooperation,optimizing regional water resources allocation,and promoting the coordination of economic and environmental sustainable development.关键词
