摘　　要：为了研究零售商存在竞争时,不同的补贴策略对绿色供应链产生的影响,构建了由一个制造商主导和两个零售商追随的二级供应链,运用Stackelberg博弈的相关理论,分别建立了NS、MSR、GSR、GSM&MSR以及GSMR五种分散决策模型,求解得到产品绿色度、低碳宣传投入以及制造商对零售商补贴比例的均衡解、政府对零售商补贴调整系数的临界值以及绿色产品的均衡需求量、制造商和零售商各自利润的最优解。结果表明,零售商之间的竞争系数与制造商和零售商的利润均呈负相关关系。比较发现:制造商对零售商补贴,需求增加所带来的利润增加超过了成本的增加,说明制造商的补贴是有效的;当政府对零售商补贴调整系数小于临界值时,制造商补贴零售商的效果更加明显。进而讨论双重补贴下,制造商和零售商的利润变化。最后运用算例验证模型的有效性。In this paper, in order to study the impact of different subsidy strategies on a green supply chain containing mutually competing retailers, we constructed a two-echelon supply chain with one dominating manufacturer and two following retailers. Then we set up five decentralized decision-making models, namely the NS, MSR, GSR, GSM&MSR, and GSMR model using the Stackelberg game model,and obtained the equilibrium solution of product greenness, low-carbon publicity input, the proportion of subsidization from the manufacturer to the retailers, the critical value of the adjustment coefficient of government subsidies to the retailers, the equilibrium demand for green products, and the respective optimal profits of the manufacturer and the retailers. The result showed that the coefficient of competition between the retailers is negatively correlated to the profits of both the manufacturer and the retailers. Through comparison, it was found that:when the manufacturer subsidized the retailers, the increase in profit brought by increased demand would exceed the increase in cost,indicating that the manufacturer’s subsidy was effective;when the government’s subsidy adjustment coefficient for the retailers was less than the critical value, the manufacturer’s subsidy to the retailers would be more effective. Next we discussed the profit changes of the manufacturer and the retailers under double subsidization. Finally, we used an example to verify the validity of the models.
