Governments　around　the　world　have　taken　measures　in　fighting　against　COVID-19,　but　how　the　government＇s　response　affects　the　public　evaluation　of　government　performance　in　crisis　remains　to　be　examined.　The　study　investigated　how　government　actions,　the　public＇s　trust　in　government,　risk　perception,　and　negative　emotions　influenced　the　public　evaluation　of　government　performance　based　on　a　primary　survey.　The　findings　showed　that:　(1)　government　actions　and　public　evaluation　of　government　performance　in　crisis　are　significantly　and　positively　associated;　(2)　trust　in　government　can　positively　lead　to　the　public　evaluation　of　government　performance　in　crisis;　(3)　risk　perception　and　negative　emotions　can　negatively　moderate　and　attenuate　the　previous　positive　relationship.　The　research　revealed　that　the　public　evaluation　of　government　performance　is　formed　by　the　government　actions　through　mediation　effect　of　trust　in　government　and　also　moderation　effect　of　risk　perception　and　emotional　factors.　Thus,　this　study　innovatively　developed　a　moderated　mediation　model　of　public　perceived　government　performance　which　may　serve　as　a　basis　for　improving　public　evaluation　while　dealing　with　the　crisis　in　other　countries　and　regions.
