Abstract

Increasingly, rural households in developing countries are shopping for food online, and the COVID-19 pandemic has accelerated this trend. In parallel, dietary guidelines worldwide recommend eating a balanced and healthy diet. With this in mind, this study explores whether online food shopping boosts dietary diversity-defined as the number of distinct food groups consumed-among rural households in China. Because people choose to shop for food online, it is important to account for the self-selection bias inherent in online food shopping. Accordingly, we estimate the treatment effects of online food shopping on dietary diversity using the endogenous switching model with a count outcome variable. The results indicate that online food shopping increases dietary diversity by 7.34%. We also find that education, asset ownership, and knowing the government's dietary guidelines are the main factors driving rural households' decisions to shop for food online.

网上食品购物能促进饮食多样性吗?带有计数结果变量的内生交换模型的应用。

发展中国家的农村家庭越来越多地在网上购买食品，COVID-19大流行加速了这一趋势。与此同时，世界各地的饮食指南都建议均衡健康的饮食。考虑到这一点，本研究探讨了网上食品购物是否促进了中国农村家庭饮食多样性——定义为消费不同食品类别的数量。因为人们选择在网上购买食品，所以考虑网上食品购物固有的自我选择偏见是很重要的。因此，我们使用带有计数结果变量的内生转换模型来估计在线食品购物对饮食多样性的治疗效果。结果表明，网上食品购物使膳食多样性增加了7.34%。我们还发现，教育程度、资产所有权和了解政府的膳食指南是推动农村家庭决定在线购买食品的主要因素。
