Ma Zhong,Shi Peiji,Hu Ke. Linkage Analysis of Water Use among Industrial Sectors in Zhangye City[J]. Advances in Earth Science, 2010, 25(6): 666-672.

The traditional linkage analysis by input/output model on water use  based on direct and indirect consumer coefficients have some limitations. Introducing modified HEM (Hypothetical Extraction Method)method, which is based on the vertically integrated measures and the linkages analysis known as the HEM, the author made an analysis the behavior of industrial sectors of Zhangye economy as direct and indirect consumers of water. With  Zhangye water use input-output regional table in 2002 applied, the results confirmed that:①In certain economic structure, there is an overall balance between the amount of virtual water and the physical water use in economy, when the total final demand is  given, its structural change will not have an impact on the total physical water use volume;②Compared with the traditional linkage analysis method, this methodology can quantify the linkages analysis of water use more explicitly.
