The significance of lockdown policies for controlling the COVID-19 pandemic is widely recognized. However, most studies have focused on individual lockdown measures. The effectiveness of lockdown policy combinations has not been examined from a configurational perspective. This research applies fuzzy-set qualitative comparative analysis (fsQCA) to examine different lockdown policy combinations associated with high-epidemic situations in 84 countries. A high-epidemic situation can occur through three different "weak-confined" patterns of lockdown policy combinations. The findings demonstrate that a combination of lockdown policies is more successful than any single lockdown policy, whereas the absence of several key measures in policy combinations can lead to a high-epidemic situation. The importance of international travel controls can become obscured when they are the only measures adopted, and a high-epidemic situation can still arise where restrictions are placed on international travel but not on public transport or when workplaces are closed but schools remain open.
封锁政策对于控制 COVID-19 大流行的意义已得到广泛认可。然而，大多数研究都集中在个别封锁措施上。从组态视角来看，尚未对封锁政策组合的有效性进行检验。本研究采用模糊集定性比较分析（fsQCA）方法，考察了 84 个国家在高疫情情况下与不同封锁政策组合相关的问题。高疫情情况可通过三种不同的“弱封闭”封锁政策组合模式发生。研究结果表明，封锁政策组合比任何单一封锁政策都更成功，而政策组合中缺少几个关键措施可能导致高疫情情况的发生。当国际旅行控制措施成为唯一采取的措施时，其重要性可能会被掩盖，而在限制国际旅行但不限制公共交通或关闭工作场所但保留学校的情况下，仍可能出现高疫情情况。
