Megaregions and COVID-19: a call for an innovative governing structure in the United States
研究发现美国大都市区（城市中心及其腹地网络）的COVID-19发病率更高，但该地理单元在跨辖区疫情应对中被忽视；通过多层次模型分析，提出大都市区可作为区域协作与治理的有效框架。
In the United States, megaregions, which are networks of urban centres and their hinterlands, have a greater prevalence of COVID-19, but have been overlooked as a geographical unit for multi-jurisdictional governance for pandemic response. Existing multi-metropolitan planning organization (MPO) collaborations and state-level COVID-19 coalitions in the United States demonstrate the utility of the megaregion as an effective framework for regional collaboration and operations. Using multilevel modelling, we explore the significance of megaregions in explaining disease occurrence. The results suggest that the megaregion can be an appropriate geographical scale for multi-jurisdictional operations, governance and pandemic response.
