摘　　要：运用水资源扩展型的投入产出法计算并分析了辽宁省2012年各产业部门的用水系数、最终消费、内部转移和外部贸易情况。结果显示:(1)辽宁省农业部门的直接、完全用水系数最大,各部门用水放大系数变化存在差异;(2)虚拟水消耗量和经济价值不匹配,产业用水结构存在不合理的现象;(3)农业是最大的虚拟水净输出部门,部门间主要的流出-流入组合包括农业-轻工业,采选业-重工业,重工业-建筑业;(4)辽宁省是虚拟水净输出地区,重工业部门的虚拟水贸易量最大且以虚拟水输出为主。Based on the input-output model of water resources expansion type,this paper calculated the water use coefficient,final consumption,internal transfers and external trade in various industrial sectors of Liaoning Province in 2012.The results showed that:(1)The direct water use coefficient and the total water use coefficient of the agricultural sector in Liaoning Province were the largest,and there were differences in the change of the water consumption multiplier;(2)Virtual water consumption and economic value did not match,and industrial water structure existed unreasonable phenomenon;(3)Agriculture is the largest virtual water net output sector,and the main output and input combinations among sectors included agriculture-light industry,mining industry-heavy industry,heavy industry-construction industry;(4)Liaoning Province was a net output area of virtual water,with the largest amount of virtual water trade in the heavy industry sector.
