The onset of the COVID-19 outbreak led to widespread adoption of mobility intervention policies, which were widely regarded as effective measures to control the spread of the virus. The initial pandemic wave, accompanied by the enforcement of mobility intervention policies, greatly changed human mobility patterns, especially cross-border mobility (CBM). This study investigates the impact of the first wave of the pandemic and related mobility intervention policies on the CBM of the senior population between Shenzhen and Hong Kong. Based on anonymous mobile phone trajectory data from 17 million devices active in Shenzhen spanning December 2019 to May 2020, we consider the implementation of mobility intervention policies during different stages of pandemic in both cities. We adopt interrupted time series (ITS) analysis to explore the causal effects of different mobility intervention policies on the CBM of older people between Hong Kong and Shenzhen. We find that most mobility intervention policies have a significant abrupt or gradual effect on the CBM of older people, especially in the 60-64 age group. As these policies neglect the mobility needs and characteristics among the senior groups, such as visiting relatives or friends and seeking medical treatment across borders, we suggest that more coordinated and integrated policies and measures are required to address the CBM needs of older people in Shenzhen and Hong Kong, especially in the post-pandemic era.
新冠疫情的爆发导致了广泛采用流动性干预政策，这些政策被广泛认为是控制病毒传播的有效措施。最初的疫情浪潮伴随着流动性干预政策的实施，极大地改变了人类的流动模式，特别是跨境流动（CBM）。本研究调查了第一波疫情和相关流动性干预政策对深圳和香港老年人群体跨境流动的影响。本研究基于 2019 年 12 月至 2020 年 5 月期间深圳 1700 万部活跃手机的匿名轨迹数据，考虑了两个城市在疫情不同阶段实施的流动性干预政策。我们采用中断时间序列（ITS）分析来探讨不同流动性干预政策对香港和深圳老年人群体跨境流动的因果影响。我们发现，大多数流动性干预政策对老年人的跨境流动有显著的突然或渐进影响，特别是在 60-64 岁年龄组。由于这些政策忽视了老年人的流动需求和特点，例如跨境探亲访友和就医，我们建议需要制定更协调和综合的政策和措施来满足深圳和香港老年人的跨境流动需求，特别是在后疫情时代。
