During the COVID-19 pandemic, the Chinese government adopted a series of preventative measures to control the spread of the virus. This paper studies the impact of the COVID-19 pandemic and its associated prevention methods on meal sharing in China. Meal gathering during multiple periods before and after the outbreak of COVID-19 is captured through two waves of online survey across China between March and June 2020, collecting a total of 1847 observations. We employ the difference-in-difference (DID) method to identify the causal effects of COVID-19 severity on meal sharing. The results show that relative to the same period in 2019, the frequency of meal gathering decreased sharply after the initial outbreak of the coronavirus in 2020 in both epicenters and non-epicenters. Furthermore, the impact of COVID-19 differed across different types of meal sharing. Our findings have implications for consumers, food service operators, as well as policymakers to understand the social and community impact of the pandemic and to adjust their coping strategies.
在 COVID-19 大流行期间，中国政府采取了一系列预防措施来控制病毒的传播。本文研究了 COVID-19 大流行及其相关预防方法对中国共餐习惯的影响。通过 2020 年 3 月至 6 月在中国进行的两轮在线调查，捕捉了 COVID-19 爆发前后多个时期的聚餐情况，共收集了 1847 个观测值。我们采用双重差分（DID）方法来识别 COVID-19 严重程度对共餐习惯的因果影响。结果表明，与 2019 年同期相比，2020 年冠状病毒最初爆发后，无论是在疫情中心还是非疫情中心，聚餐的频率都急剧下降。此外，COVID-19 对不同类型的共餐习惯的影响也不同。我们的研究结果对消费者、餐饮服务经营者以及政策制定者都具有重要意义，有助于他们了解疫情对社会和社区的影响，并调整应对策略。
