Trust can be obtained by firm location (endowed trust) or behaviors (earned trust). We are interested in whether firms located in trusted regions are more likely to protect stakeholders’ benefits as a strategy to earn trust. Based on a sample of Chinese firms, we find a significant and positive correlation between regional endowed trust and local firms’ environmental and social commitment. We suggest that endowed trust has two effects: 1) shaping local firms’ legal cognition and thus decreasing misconducts; and 2) providing resources and thus mitigating financial constraints, both of which encourage firms to protect the environment and society. Moreover, the positive effect of high endowed trust is weakened when corporate governance or local legal environment is strong.
