考虑非合意产出的省际水资源利用效率及驱动因素研究——基于SE-SBM与Tobit模型的考察
Inter-provincial water resources utilization efficiency and its driving factors considering undesirable outputs: Based on SE-SBM and Tobit model
摘要
Abstract
The shortage of water resources and water ecological deterioration has become the main factors that restrict the utilization of water resources in China.Improving the utilization efficiency of water resources is the fundamental way to solve sustainable utilization of water resources as well as the core of the new normal and supply-side reform,so it is of necessity and practical significance to study water resources utilization efficiency.The most stringent water management system was implemented and ‘ three red lines’ of utilization of water resources were established by Chinese government.The dual control of water resources in total consumption and intensity was adopted and ‘ river-chief’ system was promoted as national water governance strategy.In this paper,the capital,labor and water consumption were selected as input indexes,and the real GDP and waste water discharge were selected as desirable and undesirable output indexes.SE-SBM model was adopted to estimate inter-province water resource utilization efficiency and Tobit Model was used to explore the influence factors in 2003-2015.The research showed that the utilization efficiency presented ‘ U’ shape and the utilization efficiency was improved in most of provinces ultimately.However significant differences existed between eastern,middle and western regions of China,the efficiency is highest in Beijing,Tianjin and Shanghai,while the efficiency is the lowest in most of northwest provinces.The regional disparity of water utilization efficiency showed the significant convergence trend through coefficients of variation method.The regional economic development level,the abundance of water resource,the structure of industry and agriculture,the intensity of government intervention have significantly negative effects on water utilization efficiency while the demands of exports and imports had no significant influence on water utilization efficiency.The state should take full account of the actual conditions in various regions,and make goals of water use efficiency and water resources management policy according to local conditions.Simultaneously water-saving technology should be vigorously developed and the lever of price should be exerted in improving water resources utilization efficiency.The positive spatial spillover effects should be exploited to promote cross-regional cooperation,thereby pushing forward inter-provincial collaborative development of water resources management.关键词
