中国水资源利用秩序评价

水资源利用秩序反映了水资源供给侧效率和需求侧公平的程度。采用秩序模型对我国30个省级行政区2008—2017年的水资源利用状态进行测度,通过测量高低收入人群收入差距的变动状况度量公平程度,使用数据包络分析法将全要素生产率的增长进行分解,从而度量其效率发挥状况,将二者综合,计算水资源总秩序水平。研究结果表明:我国大多数省级行政区水资源利用纵向秩序较好、横向秩序较差,因此应采取措施,以保障水资源利用秩序保持在较高且比较稳定的水平上。

Order evaluation of utilization of water resources in China

The order of utilization of water resources reflects the degrees of efficiency of supply side and fariness of demand side. The order model is used to measure the utilization status of water resource in 30 provincial administrative regions in China from 2008 to 2017. The degree of fairness is obtained by measuring the change of income gap between high and low-income groups. The data envelopment analysis is used to decompose the growth of the total factor productivity so as to measure its efficiency. The overall order level of water resources is calculated by combining the above two aspects. The results show that the vertical order of most provincial administrative regions is better, while the horizontal order is worse. Attention should be paid to it and some measures should be taken to ensure that the order of utilization of water resources is kept at a higher and more stable level.
