To estimate the short-term economic effect of the 2013 M7.0 Lushan Earthquake, the constant mean return model and the market model of event study are adopted. On the levels of the whole stock market, some typical sectors, regional stocks, and the stock in the affected area, effects are measured. Three indices are adopted to measure the whole market. Nine indices are selected to observe the abnormal returns of the sectors, involving Energy, Materials, Industries, Consumer, Health care, Finance, Information technology, Telecommunication service, and Utilities. In Sichuan Province, there are 82 registered stocks with enough trading data, whose abnormal returns are calculated to test the short-term effect on the regional economy.
