摘　　要：考虑一条风险规避型的"单制造商—单零售商"双渠道供应链,通过求解供应链系统分别在集权模式和分权模式下最大效用的Karush-Kuhn-Tucker(KKT)条件,得到其在需求扰动前后的最优定价策略和生产决策。研究表明,风险规避系数与最优价格成反比,与最优生产量成正比,与二者的值有关,与不同决策的分界点无关;需求扰动时供应链的决策只与扰动量有关,与风险规避系数无关;集权模式下供应链知道需求扰动的价值与风险规避系数正相关。A risk-averse dual-channel supply chain made up of one manufacturer and one retailer is taken into account. By solving the Karush-Kuhn-Tucker （KKT）condition of the supply chain system in the centralized decision-making and decentralized decision-making respectively, the optimal pricing and production decisions before and after demand disruption are obtained. Some conclusions are drawn： the coefficient of risk aversion is proportional to the optimal prices but is inversely proportional to the optimal production, and it is associated with the value of the optimal prices and optimal production but has no relation with the dividing point of the decision; the decisions of the supply chain under demand disruption are only related with disruption quantity, and has nothing to do with the coefficient of risk aversion; the value of knowing the disruption in centralized decision-making of the supply chain is proportional to the coefficient of risk aversion.
