How　to　adopt　channel　strategy　is　one　of　the　important　issues　in　fresh　supply　chain　management.　Aiming　at　the　main　ways　for　consumers　to　purchase　fresh　products,　this　paper　uses　supply　chain　management　theory　to　study　the　channel　strategies　of　retailers　under　COVID-19　and　its　impact　on　fresh　supply　chain.　Firstly,　three　channels　for　consumers　to　purchase　fresh　products　under　COVID-19　and　their　characteristics　are　analyzed.　Secondly,　the　main　problems　existing　in　each　channel　under　COVID-19　are　studied.　Finally,　some　countermeasures　and　suggestions　are　put　forward　to　solve　the　main　problems　of　fresh　supply　chain.　©　2021　ACM.
