基于辽宁省14个地级市的水足迹面板数据,利用数据包络法测度了2004-2014年辽宁省各城市的水资源利用效率。从时间上看,2004-2014年辽宁省整体水资源利用效率呈上升趋势,但整体水资源利用效率较低;从空间上看,辽宁省水资源利用效率整体上呈中间高、东西两侧低的格局,且东侧高于西侧。运用空间滞后模型、空间误差模型和空间Durbin计量模型研究了辽宁省各城市水资源利用效率的空间溢出效应,发现:辽宁省水资源利用效率存在空间溢出效应,辽宁省各城市的劳均GDP、教育经费、工业和农业用水比重、农田实际灌溉平均用水量对水资源利用效率存在显著正向影响;外商直接投资和人均用对水资源利用效率存在显著负向影响;教育经费的增加、农田实际灌溉平均用水量的控制能够促进水资源利用效率上升;外商直接投资和人均用水量的增加会导致水资源利用效率降低。
Based on Liaoning Province of 14 cities panel date of water footprint, established the water resources utilization efficiency of every cities in Liaoning Province by using date envelopment analysis model in the view of time line. Overall utilization efficiency of water resources in Liaoning province was on the rise from 2004 - 2014, but the water use efficiency was low. From the space point of views, overall utilization efficiency of water resources in Liaoning Province showed the middle high, east and west on both sides of the low pattern, and the east side was higher than the west side. By mean of the spatial lag model, spatial error model and space Durbin econometric model, this paper studied the spatial spillover effects of water resources utilization efficiency every cities in Liaoning Province. The results showed that there was significant spatial correlation in water resource efficiency of every cities in Liaoning Province. The GDP per labor, the education funds, the proportion of industrial and agTicuhural water and actual irrigation water consumption per area had positive significant influence. The factors of foreign direct investment and per capita water consumption had negative significant influence. Increasing in the education funds control the actual irrigation water consumption per area could promote the water resources utilization efficiency. Increasing in the factors of foreign direct investment and per capita water consumption resulted in the reduce of the water resources utilization efficiency.
