The influence of melamine incident on dairy industry in 2008 was investigated, and the control effect of different enterprises on the black swan incident was analyzed. First of all, this paper analyzes the impact of the stock of listed companies in the dairy industry after the black swan incident, and compares the impact of the different risk treatment of several leading enterprises on the stock price recovery. The results show that: first, the melamine incident has a negative effect on the enterprises involved, and the enterprises involved do not have a competitive advantage. Second, in the same period, enterprises pay more attention to the influence of black swan event and take more powerful measures. The greater the risk treatment intensity is, the less the influence of black swan event will be. Third, the two enterprises have similar risk handling strength.
