摘　　要：城镇化和工业化的快速发展,使得位于中国北方的辽宁省水资源短缺问题日益严峻,现代化进程受到制约。基于水足迹和虚拟水理论,利用单区域投入产出法,构建"实物-价值"型水资源投入产出模型。根据2012年辽宁省投入产出表和部门的用水数据,计算辽宁省2012年各产业部门的用水系数、水足迹和虚拟水贸易量。结果表明:1)辽宁省完全用水系数和直接用水系数最高的部门是水的生产供应业,农业位居第二;2)辽宁省农业直接水足迹最高,完全水足迹和间接水足迹最高的部门是制造业;3)辽宁省是虚拟水净输出地区,虚拟水净输出量为40 009万m3。The rapid development of urbanization and industrialization has increasingly worsened the water shortage and hindered the process of modernization of Liaoning Province in the north of China.Based on water footprint and virtual water theory,the paper constructed a“physical-value”input-output model of water resources with single-region input-output method,and then figured out water use coefficient,water footprint and virtual water trade volume of different sectors in 2012,according to the input-output table and data of sector water consumption of Liaoning Province in 2012.The results showed that:1)the sector with the highest total water use coefficient and direct water use coefficient in Liaoning Province was the water supply and production industry,with agriculture ranking the second;2)in Liaoning Province,agriculture had the highest direct water footprint,and manufacturing had the highest total water footprint and indirect water footprint;3)Liaoning Province was a net output area of virtual water with a net output of 400.09 million m 3.
