The COVID-19 pandemic has fundamentally changed human mobility patterns in cities. Lockdowns, social distancing and flexible working hours have restructured pre-existing dynamics between two opposing forces in major cities: centripetal and centrifugal. To scrutinise the new dynamics, human mobility in the Seoul Metropolitan Area in early 2020 was investigated using big data collected from cell phone activity. By suggesting a network-based approach to untangle complex human mobility in the urban network, this research contributes to understanding how the COVID-19 shock impacted human mobility patterns in everyday life and how human behaviours adapted to the new normal.

由内而外：人类流动性大数据显示 COVID-19 如何改变首尔都市区的城市网络结构

COVID-19 大流行从根本上改变了城市中的人类流动模式。封锁、保持社交距离和灵活的工作时间已经重构了主要城市中两种对立力量之间的原有动态：向心力和离心力。为了审视新的动态，使用从手机活动中收集的大数据调查了 2020 年初首尔都市区的人类流动性。通过提出一种基于网络的方法来解开城市网络中复杂的人类流动，这项研究有助于了解 COVID-19 冲击如何影响日常生活中的人类流动模式以及人类行为如何适应新常态。
