摘　　要：通过期望效应理论,研究了零售商具有多个零售点时的回购契约模型。得出不同风险偏好下,实现供应链协调时的最优定购量、最优回购价格与风险系数的关系。数值分析表明,当零售商为风险中性时,回购价格随着供应商风险系数的增大而减小;当供应商为风险中性时,在订购量小于一定量的情况下,回购价格随着零售商风险系数的增大而增大,当订购量大于一定值后,回购价格为固定值。By using expectation effect theory, the buy-back contract model of the retailer with multiple outlets was studied. The relationship among the optimal quantity, the optimal buy-back price and the risk co- efficient was given when the channel coordination was realized under different risk preference. The numeri- cal analysis indicated that when retailer was risk neutral, the buy-back price decreased as the supplier＇s risk coefficient increased; when the supplier was risk neutral and the order quantity was less than a certain quantity, the buy-back price increased as the retailer＇s risk coefficient increased; and when the order quantity was larger than a certain quantity, the buy-back price became a constant.
