Dynamics of Interagency Networks under Stress in Public Health Emergencies: Evidence from China

Disasters are continuously evolving complex processes. Coupling with rapidly changing conditions, response networks must change to meet external needs and adapt to the environment. This study explores the dynamics between stress and structural and functional characteristics of response networks in the centralized political context. Semantic analysis of policy documents shows that unmet needs are an underlying driver of the formation and the dynamics of task-oriented interagency networks. Network analysis shows that the interagency network is a hybrid network that evolves from a decentralized to a centralized structure as stress decreases. Moreover, the leading organizations also shift, which confirms the coordination by feedback in emergency response. After discussing research findings, this study offers recommendations (a) to identify and empower brokers for better coordination and (b) to combine coordination by feedback and coordination by plan.
