Abstract

Although understanding initial responses to a crisis such as COVID-19 is important, existing research on the topic has not been systematically comparative. This study uses topic modeling to inductively analyze over 13,000 COVID-19 policies worldwide. This technique enables the COVID-19 policy mixes to be characterized and their cross-country variation to be compared. Significant variation was found in the intensity, density, and balance of policy mixes adopted across countries, over time, and by level of government. This study advances research on policy responses to the pandemic, specifically, and the operationalization of policy mixes, more generally.

摘要

尽管了解诸如COVID-19之类的危机的初始响应很重要，但有关该主题的现有研究尚未进行系统地比较。这项研究使用主题建模对全球13,000多个COVID-19政策进行归纳分析。这种技术使COVID-19政策组合得以表征，并且可以比较其跨国差异。人们发现，随着时间的流逝，以及政府级别的不同，各国所采用的政策组合的强度，密度和平衡存在显着差异。这项研究特别是针对大流行的政策应对和更广泛的政策组合的可操作性进行了研究。
