水资源的可持续开发利用关系到经济社会的健康发展,评价我国水资源利用效率并探讨其影响因素至关重要。运用基于投入距离函数的随机前沿分析(SFA)模型,采用2003~2011年的省级面板数据,分析了我国水资源利用效率及其影响因素。结果表明,样本期内我国水资源利用效率稳步提高,但仍有较大提升空间,且呈现“东高西低”的空间分布特点;经济发展水平、科研投入、污染治理投资、水价等对水资源利用效率有正向影响。
The sustainable development and utilization of water resources are related to the healthy development of economy and society. It is of vital importance to evaluate the efficiency of water resources utilization in China and explore its influential factors. Based on the stochastic frontier analysis (SFA) model based on the input distance function and the provincial panel data from 2003 to 2011, the utilization efficiency of water resources in our country and its influencing factors were analyzed. The results show that the utilization efficiency of water resources in our country steadily increases during the sample period, but there is still room for improvement and the spatial distribution characteristics of “high, low and high in the east”, the level of economic development, investment in scientific research, investment in pollution control, water price, etc. Positive impact on water use efficiency.
