【摘要】：绿色发展是当今时代的主题,在对传统水资源效率研究的基础上,论文界定了水资源绿色效率的概念与内涵。基于数据包络技术,进行水资源绿色效率测度,将其与传统的水资源经济效率、环境效率测度结果进行比较分析,并运用ESDA方法进行空间格局研究。研究结果发现:社会维度效应对水资源整体利用效率改进有积极作用;3种水资源利用效率均呈现出下降的趋势,并且存在不同程度的波动,水资源环境效率波动最大,水资源绿色效率次之,水资源经济效率稳定性最好;水资源绿色效率与经济发展水平没有密切的关系,经济发达地区的水资源绿色效率高,但是经济欠发达地区的水资源绿色效率也高,水资源经济效率和水资源环境效率高值地区多数分布在东部沿海地区;水资源绿色效率的空间相关性不明显,并且集聚程度逐渐减弱;2000—2014年水资源绿色效率在研究区内部存在着明显的地区差异,并且这种差异逐渐扩大;不考虑社会维度效应的水资源利用效率对水资源真实利用情况产生偏差估计,误导政策制定。
[Abstract]:Green development is the theme of the present era. Based on the study of traditional water resources efficiency, this paper defines the concept and connotation of water resources green efficiency.Based on the data envelopment technology, the green efficiency of water resources is measured and compared with the results of traditional water resources economic efficiency and environmental efficiency, and the spatial pattern is studied by using ESDA method.The results show that the social dimension effect has a positive effect on the improvement of the overall utilization efficiency of water resources. The three kinds of water resources use efficiency all show a downward trend, and there are fluctuations of different degrees, and the environmental efficiency of water resources fluctuates the most.The green efficiency of water resources is the second, the stability of economic efficiency of water resources is the best, the green efficiency of water resources is not closely related to the level of economic development, and the green efficiency of water resources in economically developed areas is high.However, the green efficiency of water resources in underdeveloped areas is also high, and most of the areas with high value of economic efficiency of water resources and environmental efficiency of water resources are distributed in the eastern coastal areas, and the spatial correlation of green efficiency of water resources is not obvious.And the degree of agglomeration gradually weakened. There were obvious regional differences in the green efficiency of water resources in the study area from 2000 to 2014, and this difference gradually expanded.The water resources utilization efficiency without considering the social dimension effect produces the deviation estimate to the water resources actual utilization situation, misleads the policy formulation.
