A　supply　chain　with　a　risk　neutral　supplier　and　multiple　risk　preference　retailers　is　studied.　It　is　assumed　that　the　market　demand　is　random　and　each　retailer＇s　demand　is　directly　proportional　to　its　ordering　quantity.　The　mean　CVaR　criterion　is　used　to　describe　the　retailers＇　attitudes　towards　risk.　In　the　retailers　symmetric,　the　monotonicity　of　the　total　balance　order　quantity　of　the　system　about　retailers＇　number　and　risk　preference　coefficient　is　obtained.　It　is　proved　that　when　the　risk　appetite　coefficient　meets　certain　conditions,　the　wholesale　contract　can　coordinate　the　supply　chain,　and　the　larger　stochastic　demand　leads　to　higher　total　balance　order　quantity　of　the　system.　The　numerical　example　is　given　to　illustrate　the　influence　of　demand　variability　on　the　total　balance　order　quantity　of　the　system.　©　2015,　Northeast　University.　All　right　reserved.
