城市间联系强度对COVID-19疫情跨区域传播的影响研究
首发时间:2020-03-31
摘要:中国COVID-19疫情已经得到了有效控制,研究疫情跨地区之间传播的规律,无论对未来疫情防控,还是对中国以外国家或地区COVID-19的防控,都具有重要意义。在本研究中,基于概率和最短路径树的"有效距离"表征城市之间的跨区域联系强度,通过COVID-19疫情发生数等高频数据,进行实证分析。得出结论认为,城市间联系强度越高,疫情跨区域传播规模越大。本文的研究结果或许对今后更好地防控疫情传播,具有一定的参考价值。

Research on the Influence of Inter-city Connection Intensity on the Cross-regional Transmission of COVID-19
Abstract:he COVID-19 epidemic in China has been effectively controlled. It is of great significance to study the law of cross-regional spread of the epidemic, for the prevention and control of the COVID-19 in the future in China and other countries or regions. In this study, the cross-regional connection intensity between cities was characterized based on the probability and the effective distance of the shortest path tree, and the empirical analysis was carried out based on the high-frequency data such as the cases of COVID 19 outbreaks. It is concluded that the higher the intensity of inter-city connection, the larger scale the cross-regional spread of the epidemic.
