Credibility is very important for non-profit organizations, which directly affects the public fundraising ability of non-profit organizations, so it is more important for foundations, especially public foundations. The credibility of a foundation comes from the degree of social recognition and trust accumulated during the operation of the organization, and good credibility comes from observing legal constraints and self-discipline norms. After a series of events in the public welfare industry were exposed in 21, the credibility crisis became a serious problem that the foundation industry must face. This problem led to a large reduction in social donations received by some foundations in the following years. In the Ya 'an earthquake in April 213, the impact of the credibility crisis was further reflected. At the end of 211, Shenzhen One Foundation Public Welfare Foundation, a private public offering foundation, received the most social donations, while the performance of individual foundations that received many donations in Wenchuan earthquake was much worse. In order to enhance its credibility, the foundation must strengthen its information disclosure and improve its interaction and communication with the public in its daily work.
