本文从投入产出分析的角度对虚拟水流量进行了解释和说明。使用澳大利亚维多利亚州的案例研究，它表明，输入-输出分析可以枚举虚拟水流量没有系统的和未知的截断误差，一个问题，这在很大程度上是缺席的虚拟水文献。从生产者的角度来看，简化的流量分析将维多利亚描绘为净虚拟水进口国，而使用输入-输出分析列举整个供应链中的水实施例显示维多利亚是一个重要的净虚拟水出口国。这项研究成功地为澳大利亚政府的政策提供了信息，这是一个令人鼓舞的迹象，表明投入产出分析将能够为其他国家和国际应用提供很大的价值。
This article explains and interprets virtual water flows from the well‐established perspective of input‐output analysis. Using a case study of the Australian state of Victoria, it demonstrates that input‐output analysis can enumerate virtual water flows without systematic and unknown truncation errors, an issue which has been largely absent from the virtual water literature. Whereas a simplified flow analysis from a producer perspective would portray Victoria as a net virtual water importer, enumerating the water embodiments across the full supply chain using input‐output analysis shows Victoria as a significant net virtual water exporter. This study has succeeded in informing government policy in Australia, which is an encouraging sign that input‐output analysis will be able to contribute much value to other national and international applications.
