The COVID-19 pandemic has profoundly affected people's daily lives, including their dietary behaviors. Using a panel data set of 31 provinces from 2015 to 2020, this study employed two-way fixed effects (FE) models to examine the impacts of the COVID-19 pandemic on dietary consumption among Chinese residents. The results showed that the COVID-19 pandemic positively affected residents' consumption of grain, eggs, dairy, and white meat (poultry and aquatic products), while it had a negative effect on individuals' red meat consumption in both urban and rural areas. These results were robust to different measures of the COVID-19 pandemic, including the number of confirmed cases, suspect cases, and dead cases. Comparatively, the changes in food consumption induced by the COVID-19 pandemic were more prominent for Chinese residents who lived in rural areas than urban areas. In addition, compared to their counterparts, the dietary consequences of the pandemic were more pronounced for residents living in the eastern region and regions with a high old-age dependency ratio and low illiteracy rate. Furthermore, the estimation results of the quantile regression model for panel data suggested that the COVID-19 pandemic had relatively larger impacts on the dietary consumption of Chinese residents at lower quantiles of food consumption compared with those at higher quantiles. Overall, the results of this study suggested that Chinese residents had a healthier diet after the outbreak of the COVID-19 pandemic. We discussed possible mechanisms, including health awareness, income, food supply and prices, and other behavioral changes during COVID-19 (e.g., physical activity and cooking). To further improve residents' dietary behaviors and health, our study proposed relevant measures, such as increasing residents' dietary knowledge, ensuring employment and income, and strengthening the food supply chain resilience during the pandemic.
新型冠状病毒肺炎疫情(COVID-19)对人们的日常生活产生了深远影响,包括其饮食行为。本研究利用 2015 年至 2020 年 31 个省份的面板数据集,采用双向固定效应(FE)模型,考察了 COVID-19 疫情对中国居民饮食消费的影响。结果表明,COVID-19 疫情对居民粮食、蛋类、奶类和白肉(禽肉和水产品)的消费产生了正向影响,而对城乡居民的红肉消费产生了负向影响。这些结果在不同的 COVID-19 疫情衡量指标下都是稳健的,包括确诊病例、疑似病例和死亡病例数。相比之下,COVID-19 疫情对农村居民的食物消费变化的影响更为显著。此外,与城市居民相比,疫情对东部地区和老年抚养比高、文盲率低地区居民的饮食影响更为明显。此外,面板数据分位数回归模型的估计结果表明,COVID-19 疫情对中国居民较低食物消费分位数的饮食消费的影响相对较大,而对较高分位数的影响较小。总的来说,本研究结果表明,COVID-19 疫情爆发后,中国居民的饮食更为健康。我们讨论了可能的机制,包括健康意识、收入、食品供应和价格以及 COVID-19 期间的其他行为变化(如体育活动和烹饪)。为了进一步改善居民的饮食行为和健康,我们提出了相关措施,如增加居民的饮食知识、确保就业和收入,以及在疫情期间加强食品供应链的弹性。
