【摘要】：为实现水资源的高效利用和生态环境价值,必须把非合意产出纳入水资源利用效率的研究范畴。使用2003—2013年中国30个省市的面板数据,选取Malmquist-Luenberger生产率指数测算了考虑环境污染的绿色水资源利用效率,在此基础上,进行了各地区水资源利用效率的收敛性检验,研究结果表明:1)针对全国而言,环境约束下的动态绿色水资源利用效率低于无环境约束得到的水资源利用效率,即忽视非合意产出时水资源利用效率被高估,这也表明传统的水资源利用效率数值的"虚高"是以水生态破坏为代价的。2)全国绿色水资源利用效率增长3.3%,其中,技术进步对水资源利用效率增长起到了正向作用,但技术效率却对改善水资源利用效率起了阻碍作用。3)全国、东部和中部区域绿色水资源利用效率增长率趋向于稳态,但西部区域的增长率虽存在条件β收敛,但不存在绝对β收敛。最后根据研究结果,提出高度重视水资源的经济价值和生态环境功能;紧扣自主创新和产业结构调整主线,通过技术进步大幅提升绿色水资源利用效率及建立节水减排的内在动力机制,缩小绿色水资源利用率的地区差距等建议。
[Abstract]:In order to realize the efficient utilization of water resources and the value of ecological environment, it is necessary to bring non-desirable output into the research category of water use efficiency. The panel data of 30 provinces and cities in China from 2003 to 2013 are used. Malmquist-Luenberger productivity index was selected to calculate the efficiency of green water resources utilization considering environmental pollution. The convergence test of water resources utilization efficiency in different regions is carried out, and the results show that: 1) is for the whole country. The dynamic green water use efficiency under environmental constraints is lower than that obtained without environmental constraints, that is, the water resources utilization efficiency is overestimated when the undesirable output is ignored. This also shows that the "virtual high" of the traditional value of water resources utilization efficiency is at the cost of water ecological destruction. 2) the national green water resources use efficiency increases by 3.3%, among which. Technological progress has played a positive role in the increase of water resources utilization efficiency, but technical efficiency has hindered the improvement of water resources utilization efficiency. The growth rate of green water resource utilization efficiency in the eastern and central regions tends to steady, but the growth rate in the western region is conditional 尾 convergence, but there is no absolute 尾 convergence. Finally, according to the results of the study. We should attach great importance to the economic value and ecological environment function of water resources. Following the main line of independent innovation and industrial structure adjustment, it is suggested that the utilization efficiency of green water resources should be greatly improved through technological progress, and the internal motive mechanism of saving water and reducing emissions should be set up, and the regional disparity of utilization ratio of green water resources should be narrowed, and so on.
