From the three cases we found that the market basically does not appear in the steady state of the larger changes in circumstances, the irresponsible behavior of listed companies had a negative impact; therefore, a listed company in the course of development should assume social responsibility. However, for different types of events, the impact is different, and sometimes have the opportunity to combine the characteristics of the information released, and then we found the importance of social responsibility to the enterprises.
