制造商为了激励零售商订购更多数量的产品，会在产品零售价下调时提供给零售商一定的补偿，如何制定最优补偿机制是提高供应链收益的关键问题。为此，建立了两阶段销售差价补偿机制下制造商与零售商的博弈模型，分析了纳什均衡解和Stackelberg均衡解下制造商对零售商的差价补偿机制的决策行为，导出了在最优让步均衡策略下差价补偿机制定量关系，并提出了求解给定差价补偿系数下的近似最优让步均衡策略的算法。通过智能产品算例的分析，表明差价补偿机制能提高供应链的期望收益，增加零售商的订购量，进一步，说明差价补偿机制可以有效地改善零供关系。

In the supply chain, suppliers provide retailers with a compensation mechanism after the price of products is reduced, so as to encourage retailers to order more products. Therefore, we establish a price difference compensation mechanism model between manufacturer and retailer about a two stage sales. Firstly, we analyze results of the Nash equilibrium strategy and Stackelberg equilibrium strategy under the manufacturer to the retailer's price difference compensation mechanism of decision-making behavior. And then we obtain quantitative relationship of the price difference compensation mechanism under the optimal compromise equilibrium strategies. An algorithm of the approximate optimal compromise equilibrium strategy is proposed at a given price difference compensation coefficient. The case study of intelligent products shows that the mechanism of price difference compensation can improve the expected revenue of supply chain and increase the order quantity of retailers. It shows that the mechanism of price difference compensation can effectively improve relationships between suppliers and retailers.
