Online community group food purchasing during the COVID-19 pandemic: Food security, problems, and sustainability

The outbreak of the COVID-10 variant Omicron epidemic in Shanghai in 2022 had a huge impact on residents' food security. This study examines the roles, challenges, and sustainability of online community group food purchasing by analyzing survey data collected from 1168 households in Shanghai between March and May 2022, in the aftermath of COVID-19. This study demonstrates that online community group food purchasing played a crucial role in ensuring residents' food access and food security during the pandemic. However, this study also reveals that residents expressed concerns about the risk of epidemic transmission, food safety, increased prices, and difficulty in safeguarding rights. Only 21.5 % of residents are willing to continue using online community group purchasing. Based on the above conclusions, this study offers some suggestions.

When helping is risky: The influence of ethical attributes on consumers’ willingness to buy farmer-assisting agricultural products online

Chinese e-commerce platforms have long helped to sell agricultural products through farmer-assisting marketing activities, effectively alleviating the problem of stagnant agricultural products in some areas, and have become a valuable cause-related marketing strategy. The ethical attributes of farmer-assisting agricultural products have unique value compared with other agricultural products. However, the existing research rarely pays attention to the influence of the ethical attributes of farmer-assisting agricultural products on consumers’ willingness to buy farmer-assisting agricultural products online. Based on collective efficacy theory and risk perception theory, this study systematically explores the influence mechanism of ethical attributes (symbolic ethical attribute and functional ethical attribute) on consumers’ willingness to buy farmer-assisting agricultural products online through three situational experiments. The results show that compared with functional ethical attributes, symbolic ethical attributes have a more positive impact on consumers’ willingness to buy farmer-assisting agricultural products online. In addition, it further reveals two mediating pathways of ethical effects (collective efficacy and risk perception) and boundaries (emergency of farmer-assisting events). This study helps to understand the ethical attributes of farmer-assisting agricultural products, and provides some practical suggestions for e-commerce enterprises implementing farmer-assisting marketing communication activities or marketers developing and promoting farmer-assisting agricultural products.
