“…In addition to these anecdotal case reports, there are also a growing (yet limited) number of studies using microlevel survey data to investigate the dynamics and heterogeneities of consumers’ buying behaviors ( Ellison et al, 2020 , Gao et al, 2020 , Moon et al, 2021 , Wang and Na, 2020 ) and of enterprises’ reaction behaviors ( Rybaczewska et al, 2021 , Dannenberg et al, 2020 , Mahajan and Tomar, 2020 , Priambodo et al, 2021 ; Shafi et al, 2020). Studies about consumers’ purchasing behaviors based on internet survey data from a few hundred consumers have generally found that the occurrence of COVID-19 and its subsequent control measures have encouraged the shift of consumers’ purchasing behaviors of food from offline to online channels worldwide (e.g., Chenarides et al, 2021 , Ellison et al, 2020 on U.S., Wang and Na, 2020 , Gao et al, 2020 on China; Mehrolia, et al 2020 on India, Moon et al, 2021 on Korea).…”
