This study examined the global media citation network of COVID-19-related news at two stages of the pandemic alert phase, i.e., the national level alert stage and the global level alert stage. The findings reveal that the small-world pattern and scale-free property of media citation networks contributed to the rapid spread of COVID-19-related news around the world. Within the networks, a small number of media outlets from a few countries formed the backbone of the network to control the risk communication; meanwhile, many media of geographical and cultural similarities formed cross-border collaborative cliques in the periphery of the network. When the alert phase escalated from the national level to the global level, the network demonstrated a number of changes. The findings contribute to the understanding of risk communication for international public health emergencies by taking into account the network perspective and evolutionary nature of public health emergencies in analysis.
本研究考察了 COVID-19 相关新闻在大流行警戒阶段的两个阶段（即国家警戒阶段和全球警戒阶段）的全球媒体引用网络。研究结果表明，媒体引用网络的小世界模式和无标度特性促进了 COVID-19 相关新闻在全球范围内的快速传播。在这些网络中，少数来自几个国家的媒体构成了网络的骨干，以控制风险传播；同时，许多地理和文化相似的媒体在网络的外围形成了跨境合作集团。当警戒阶段从国家层面上升到全球层面时，网络显示出了一些变化。这些发现通过在分析中考虑到公共卫生突发事件的网络视角和演变性质，有助于理解国际公共卫生突发事件的风险沟通。
