Abstract

The aim of this study is to find a reasonable indicator to evaluate by sector water use efficiency (WUE). Based on a water resource input-occupancy-output model, a new indicator (total water use coefficient) that considered indirect demand effects and occupancy was provided. Use this indicator and the commonly used indicator (direct water use coefficient), WUE by 19 sectors in Beijing in 2002 and 2007 was evaluated. Results showed that to each sector, its total water use coefficient is bigger than its direct water use coefficient. The order of WUE for 19 sectors was different with the two indicators. This indicated that, when one evaluated WUE, the indirect water consumption couldn't be ignored. The new indicator (total water use coefficient) was more reasonable.
