Abstract: Based on the amount and the number of corporate philanthropic donation after “5·12” Wenchuan Earthquake, the paper conducts an empirical research on how the features of 31 provinces of China mainland influence the corporate philanthropic behavior. The results show that each province’s policy environment, the economic development level and corporate network have significant influence on corporate philanthropic behavior. It shows the amount and number of enterprises donations are directly proportional to the province’s level of economic development. And there exists government-oriented power in corporate philanthropy in China. At last, corporate donations behavior is also affected by the degree of tightness of local corporate networks in a given region.
