摘要
水权交易是水资源利用效益最大化、效率最优化的有效途径之一。选用中国大陆31个省(自治区、直辖市)2005—2019年的面板数据评估我国水权交易试点政策对水资源利用效率的影响。首先运用非期望产出超效率全局SBM模型测度各地水资源利用效率,然后基于RCM(回归控制法)对水权交易政策进行反事实分析。研究结果表明:(1)近十几年我国水资源利用效率平均水平不高,提升空间较大;(2)从时间变化来看,以2015年为拐点水资源利用效率呈现“先降后升”的U型变化趋势;(3)从空间分布来看,各地水资源利用效率地区差异悬殊,主要与各地经济发展水平、对外开放程度、产业结构状况及水资源禀赋等因素相关,整体呈现“东高西低、沿海高内陆低”的分布状态;(4)基于回归控制法的分析结果表明,水权交易政策具有显著提高试点省(区)水资源利用效率的作用,且政策效果受地区经济技术发展和市场活力影响。
Water rights trading is one of the effective ways to maximize the benefits and efficiency of water resource utilization. This paper selects the panel data of 31 provinces of Chinese mainland from 2005 to 2019 to evaluate the impact of China’s water rights trading pilot policies on water resource utilization efficiency. This study uses the global SBM model of undesirable output super-efficiency to measure the water use efficiency of each province,and then conducts a counterfactual analysis of the water rights trading policy based on RCM(regression control method). The research results show that:(1)the average level of China’s water resources utilization efficiency is not high in the past ten years,and there is a large room for improvement.(2)From the perspective of time,the water resources utilization efficiency showed a "first decline and then an increase" with 2015 as the turning point.(3)From the perspective of spatial distribution,the regional differences in water resource utilization efficiency greatly varied between provinces,which are mainly related to factors such as the level of economic development,degree of opening to the outside world,industrial structure,and water resources endowment.(4)Based on the regression control method,the analysis results show that water rights trading policy can significantly improve the utilization efficiency of water resources in pilot provinces(regions),and the policy effect is affected by regional economic and technological development and market vitality.
