Analysis on Variation and Factors of Water Resources Consumption Intensity in China

In China, water resources consumption intensity (WI) was obviously decreased during 1997–2008. Based on complete decomposition model, the paper makes a profound analysis on the variation and factors of WI from the point of industry. The results show that the decline of total WI was caused by both adjustment of industrial structure and increase of water utilization efficiency in various industries. Particularly, the decline of economic proportion of primary industry and the increase of water utilization efficiency of primary and secondary industry played an important role in the decline of WI. And WI has plenty of space to decline, so the water utilization efficiency should be continuously improved.
