Impacts　of　risk　preference　and　demand　uncertainty　on　the　optimal　order　quantity　and　profit　in　supply　chain　system　with　mixture　conditional　value-at-risk　constrain　are　studied　by　using　stochastic　dominance.　It　is　proved　that　the　optimal　order　quantity　and　profit　of　the　retailer　will　decrease　while　risk　preference　coefficient　increases　under　the　wholesale　price　contract　and　revenue　sharing　contract.　The　wholesale　price　contract　can　coordinate　the　supply　chain　system　only　when　the　retailer　is　risk-taking.　The　supply　chain　system　can　also　be　coordinated　by　the　revenue　sharing　contract　for　any　risk　preference　of　the　retailer.　Under　the　revenue　sharing　contract,　stochastic　larger　demand　leads　to　higher　optimal　profit　of　the　retailer;　more　variable　demand　leads　to　less　profit　of　the　retailer　when　risk　preference　coefficient　is　larger　than　or　equal　to　one.　©,　2014,　Northeast　University.　All　right　reserved.
