The rainstorm comprehensive economic loss assessment based on CGE model: using a July heavy rainstorm in Beijing as an example

This paper introduces the computable general equilibrium (CGE) model into the comprehensive economic loss assessment due to rainstorm, using Beijing as an example. The article has constructed a regional storm disaster CGE model to measure the impacts made by rainstorm occurence on sectors and the whole economic system by adding four disaster impact parameters corresponding to the four most affected sectors. The evaluation results show that the torrential rain on July 21 of 2012 in Beijing has caused a total of more than 27 billion RMB of indirect economic loss, which is much more than 11.64 billion RMB of direct economic loss, and on the other hand, we find that, although the rainstorm has brought immense losses to multiple economic departments, it stimulates the increase of social employment rate and investment in fixed assets.
