探讨了双寡头制造商和一个零售商构成的二阶绿色供应链的竞合关系和研发模式选择问题。基于两制造商间的横向竞合关系及是否共同研发,构建了四种博弈模型,给出了各种情景下的均衡绿色度和均衡价格,分析了竞合关系和研发模式对供应链成员绩效和策略选择的影响。数值算例分析表明:合作与共同研发策略可使制造商获得最大收益,却不会使零售商获益最大;共同研发加剧的竞争会使制造商受损,但零售商却可从中受益;竞争程度和绿色度敏感系数会影响制造商和零售商的策略选择。
Discusses the competing relationship and researching mode of the second-order green supply chain formed by the duopoly manufacturer and a retailer. Based on the horizontal competition and cooperation between the two manufacturers and whether they jointly developed or not, four game models were constructed, and the equilibrium greenness and equilibrium price under various scenarios were given. The effects of competing relationship and R & D on the performance of supply chain members And the impact of strategy choices. Numerical examples show that cooperative and joint R & D strategies can maximize the profitability of the manufacturer without benefiting the retailers. Co-development of the intensified competition can damage the manufacturer, but the retailer can benefit from it. The competition The degree and greenness sensitivity factors affect the tactical choices of manufacturers and retailers.
