【摘要】：选取我国大陆30个省(市、自治区)的2004—2014年间相关统计数据,运用超效率DEA-Tobit两阶段模型对水资源效率进行评价,并对水资源效率的区域差异及其影响因素进行分析。水资源效率的区域差异分析结果表明:我国水资源效率相对较低,仅北京、天津、青海三省市的水资源效率高于1,其余大部分省市水资源效率处于0~0.2之间;同时,我国水资源效率还存在区域差异,东部地区高于中西部地区,华北、西北地区相较于其他区域处于较高水平。水资源效率区域差异的影响因素分析结果发现:水资源效率与治理废水项目完成投资额和产业用水结构呈负相关关系,与供水总量和科技水平呈正相关关系。因此,为了进一步提升水资源效率,必须在发展经济的同时,加大科技投入,提升科技水平,优化产业用水结构。
[Abstract]:Based on the statistical data of 30 provinces (municipalities and autonomous regions) in mainland China from 2004 to 2014, this paper evaluates the efficiency of water resources by using the super-efficiency DEA-Tobit two-stage model. The regional differences of water resources efficiency and its influencing factors are analyzed. The results show that water resources efficiency is relatively low in China, only in Beijing and Tianjin. The water resource efficiency of the three provinces and cities in Qinghai is higher than 1, while the water resources efficiency of most other provinces and cities is between 0 and 0.2. At the same time, there are regional differences in the efficiency of water resources in China. Compared with other regions, Northwest China is at a higher level. The results show that the water resources efficiency is negatively related to the investment of wastewater treatment projects and the structure of industrial water use. Therefore, in order to further improve the efficiency of water resources, we must increase the investment of science and technology, improve the level of science and technology, and optimize the structure of industrial water use while developing economy.
