Taking Yangtze River Delta Basin as an example, indirect economic impacts of water pollution in 2011 on sub-regions (Shanghai, Zhejiang and Jiangsu) were simulated based on a basin scale multi-regional computable general equilibrium (CGE) model. Moreover, an indirect effect coefficient (IDE) was been built to reflect the degree of indirect effect of water pollution on each sub-region and sector. The results indicated that economic impacts of water pollution had significant differences in three sub-regions of Yangtze River Delta Basin. The loss in GDP in Shanghai was the highest (16.13 billion Yuan), whereas the ratio of GDP loss in Zhejiang decreased most significantly (2.84%). In addition, the IDE of Shanghai, Zhejiang and Jiangsu were 3.47, 1.98 and 0.92 respectively, which means that the economy of Shanghai was most sensitive to water pollution occurred in the Yangtze River Delta Basin than other two regions.
