摘　　要：将国内外基于投入产出模型的虚拟水研究进行系统概括,认为按研究层面可以归纳为区域之间的虚拟水贸易和产业间部门用水关联两方面,并指出:(1)目前基于投入产出分析技术的虚拟水研究基本建立在价值型投入产出模型的基础上,实际上将产业虚拟水替代了原本产品虚拟水的概念。(2)目前针对工业品、服务品的虚拟水量化研究不足,并未独立研究非农产品虚拟水量化时的差异性。最后文章提出产业生态学中近年来发展的混合生命周期评价方法(Hybrid life-cycle assessment,HLCA)。Researches on virtual water based on input - output model at home and abroad are generalized systematically. It can be divided into two aspects according to the research level. One part is about virtual water trade among regions; the other is about department water connection between industry. It is pointed out that l ） At present, input - outpu~ analysis of virtual water are mainly established on the basis of value input - output model, the original concept of product virtual water are replaced by the concept of industry virtual water actually. 2） Applying input - output analysis for virtual water quantification of industrial products and service products is lacking, and the differences in the virtual water study of non - agricultural products is not studied separate- ly. Therefore, the hybrid life cycle assessment（HLCA）is proposed.
