中文摘要:虚拟水是凝结在产品和服务过程中所需要的水资源量。通过组合运用投入产出分析法与水足迹法,对长江中下游五省41个部门的虚拟水贸易进行测算,结果表明:五省中的四省以虚拟水贸易形式向其它地区输出了大量水资源,其中农林牧渔业是生产和输出水资源量最大的部门;并且省份间农畜产品的虚拟水流动存在较大差异,据此,各省份应调整进出口策略,优化产业结构和布局,综合实施虚拟水贸易策略。

Study on Virtual Water Trading Strategy Aimed at Alleviating China's Aridity Problem:Case Study of Five Provinces in Middle and Lower Reaches of the Yangtze River
Abstract:Virtual water is the amount of water used in the production of a good or services. Taken the five provinces in middle and lower reaches of the yangtze river as an example, the virtual water trade flows has been calculated using both input output analysis and water footprint method. The results show that four of the five provinces have exported a large quantity of water resources to other areas in the form of virtual water trade. And the majority water resources are produced by the forestry, animal, husbandry and fishery. However, big inter provincial difference has existed in the production of virtual water. So every province should adjust its strategy of export and import, optimize the industrial structure and layout, and use the virtual water strategy.
