摘　　要：文章研究了考虑生产商风险管理因素并存在为购买绿色商品的零售商提供价格补贴的绿色供应链网络均衡模型,可以有效降低风险损失,提高竞争优势。该供应链由生产商、零售商、消费市场的三层结构组成,分析了损失函数表达供应链中的中断风险特征及生产商、零售商、消费市场的行为优化条件,将供应链网络均衡问题转化为广义纳什均衡问题,通过证明广义纳什均衡解的存在性证明得到供应链网络均衡问题的解也是存在的,并提供数值算例以验证其合理性。The research shows that the green supply chain network equilibrium model that considers producer risk management factors and provides price subsidies for retailers to purchase green products can reduce risk losses and improve competitive advantage.This supply chain comprises a three-tier structure of manufacturers,retailers,and demand markets.This study analyzes the loss function that ex⁃presses the characteristics of disruption risk in the supply chain and the optimal conditions for the behav⁃ior of manufacturers,retailers,and demand markets and transform the supply chain network equilibrium problem into a Generalized Nash equilibrium problem.By proving the existence of the Generalized Nash equilibrium solution,it is proved that the solution to the supply chain network equilibrium problem also exists,and a numerical example is provided to verify its rationality.
