Abstract: In this paper, we study the influence of emergency cooperation relationship on status differences, personal power, and social power, and test the mediating effect of individual power and social power in group status differences and the relationship among organizations, as well as the regulating effect of risk perception on the relationship between personal power and social power and emergency cooperation. Research results show that the status differences, personal power, and social power have a significant influence on the emergency cooperation relationship. The differences in organization have negative influences on the emergency cooperation relationship, and personal power and social power have positive influences on the emergency cooperation relationship. Status differences affect the emergency cooperation through the personal power and social power, meanwhile the risk perception regulates the relationship between the personal power and social power and the emergency cooperation. Finally, it is proposed that the high-level emergency conductor should regulate the power allocation among organizations according to the risk differences.
