Substantial empirical studies show that the reaction of the stock market to the information of outside world is asymmetric, this stylized fact is of great significance, if the variance of market returns can measure market risk, the market asymmetric response may result asymmetric risk premium in the stock market, asymmetric risk premiums on the stock market would be have impact on asset pricing, portfolio construction and risk position, so asymmetric reaction of the stock market has been the focus of attention of academics and investors, learning from the latest researching approach in domestic and foreign, on the basis of the actual situation in china ' s securities market, a more detailed study of china ' s shanghai and shenzhen stock a, b four markets have been done
