In the People’s Republic of China, charitable foundations are a new phenomenon and an innovative form of social organization. Since 2004, when the new Regulations on the Administration of Foundations went into effect, the number of charitable foundations has grown quickly. In spite of its potential and the important role the foundation sector can play in China’s social development, effective media supervision can help charitable foundations grow. Media monitoring plays an indispensable role in social governance. Based on the evolutionary model theory, a model involving government, media, and charitable organizations is constructed. Our study highlights the influence of media supervision on the strategic behavior of charitable organizations and government supervision departments. The research finds a certain degree of a substitution relationship between media supervision and government supervision; the intensification of media supervision is conducive to encouraging government regulatory departments to choose regulatory strategies and charitable organizations to choose legal and compliant operation strategies. The National Kidney Foundation event in Singapore and the Spring Bud Project event of China Children and Teenagers’ Foundation were taken as cases to verify and respond to the important influence of media supervision in charitable organizations. Media supervision can help reduce corruption by promoting good governance, strengthening reform-oriented initiatives, reducing the likelihood of corrupt behavior, improving relationships between government employees and public members, letting donors be aware of government activities, and monitoring and controlling the behavior of government employees.
