The　outbreak　of　COVID-19　has　disrupted　people＇s　pace　of　life　and　greatly　affected　the　normal　development　of　industry　and　commerce.　Different　types　of　enterprises　have　experienced　different　degrees　of　losses.　The　e-commerce　companies,　which　rely　on　both　labor　and　information　techniques,　have　been　influenced　obviously.　To　investigate　the　resilience　supply　chains　of　e-commerce　companies　in　the　post-epidemic　era,　we　choose　Jingdong　(JD)　as　an　example　and　identify　their　performances　during　this　specific　period.　According　to　our　analysis,　JD　has　shown　its　strong　supply　chain　management　and　service　ability　in　the　post-epidemic　period　of　resuming　work　and　production.　Moreover,　the　functions　of　the　digital　technology　integration　system　of　the　JD　Smart　Purchasing　Platform　are　also　demonstrated.　It　provides　integrated　supply　chain　service　and　procurement　project　service　that　faces　those　relative　enterprises.　In　conclusion,　applying　the　Information　Visualization　management　system　could　provide　an　efficient　reference　for　supply　chain　management　of　e-commerce　companies.　©　2021　IEEE.
