| 摘 要： | 以中国西部地区12个省（自治区、直辖市）为研究对象，采用含有非期望产出的SBM-Windows模型测算了2000—2018年中国西部地区整体和不同产业部门的水资源利用效率，并在此基础上实证分析了环境规制对西部地区水资源利用效率的影响。研究表明：① 在维持现有技术水平不变的前提下，西部地区整体水资源利用效率仍有33.89%的改进潜力。② 样本期内西部地区的水资源利用效率呈现出先上升后下降的趋势。区域间、产业部门间水资源利用效率存在明显的差异性，具体表现为西南地区的水资源利用效率明显高于西北地区，工业部门的水资源利用效率高于农业部门。③ 环境规制抑制了西部地区水资源利用效率的提升。从产业部门和资源依赖程度差异性的角度来看，环境规制对工业部门水资源利用效率的提升具有不利影响，且对高资源依赖度地区水资源利用效率的提升具有显著的负向影响。

| Abstract: | Focusing on 12 provinces (autonomous regions and municipalities directly under the Gentral Government) in the western China, the article uses the SBM-Windows model with undesirable outputs to estimate the water resource utilization efficiency of the whole and different industrial sectors in the western China from 2000 to 2018, and then empirically analyzes the impact of environmental regulations on water resource use efficiency in the western China. The results show that: 1) Maintaining the existing technical level, the overall water utilization efficiency in the western region still has 33.89% improvement potential. 2) During the sample period, the water resource utilization efficiency in western China showed a trend of increasing first and then decreasing. There are obvious differences in the utilization efficiency of water resources among different regions and industrial sectors. Specifically, the water utilization efficiency in the southwest China is significantly higher than that in the northwestern China, and the water utilization efficiency of industrial sector is higher than that of agricultural sector. 3) Environmental regulations inhibit the improvement of water resources utilization efficiency in the western China. From the difference between industrial sectors and resource dependence degree, environmental regulation has an adverse effect on the improvement of water resource use efficiency in industrial sector, and has a significant negative impact on the improvement of water resource use efficiency in areas with high resource dependence degree. |
