Drawing upon the concept of longitudinal multiplexity and the Institutional Collection Action (ICA) framework, this article conducts a longitudinal observation of online emergency collaborative networks (ECNs) built and sustained among organizational actors within Shenzhen and Hong Kong in response to Typhoon Mangkhut. In addition to investigating the multiplex relationships among three types of online ECNs (i.e., preparedness networks, response networks, recovery networks), this article takes a comparative approach to examining how the structural constraints imposed by distinct emergency management systems (EMSs) influence the network formation and evolution as the disaster evolves over time. Findings obtained from a series of inferential network analyses reveal that preexisting online collaborative ties formed at the disaster preparedness stage are important for increasing organizations' tendency to build and sustain online collaborations during disaster response and recovery. Moreover, the decentralized EMS in Hong Kong exhibits more effectiveness in facilitating online network changes during both transitional periods. These findings demonstrate a pressing need for emergency researchers and frontline communication managers to understand the dynamic relationships among online ECNs across different disaster phases and further explore potential opportunities to facilitate online emergency collaboration on a broader scale.
本文借鉴纵向多重性和机构集合行动（ICA）框架的概念，对深圳和香港的组织行为者为应对台风“山竹”而建立和维持的在线应急协作网络（ECN）进行了纵向观察。除了调查三种类型的在线 ECN（即备灾网络、响应网络和恢复网络）之间的多重关系外，本文还采用比较方法，研究了不同应急管理系统（EMS）施加的结构约束如何随着时间的推移影响网络的形成和演变。从一系列推理网络分析中得出的发现表明，在灾害准备阶段形成的现有在线协作联系对于增加组织在灾害应对和恢复期间建立和维持在线协作的倾向很重要。此外，香港分散的 EMS 在促进灾害过渡阶段的在线网络变化方面更有效。这些发现表明，应急研究人员和一线沟通管理人员迫切需要了解不同灾害阶段在线 ECN 之间的动态关系，并进一步探索促进更广泛的在线应急协作的潜在机会。
