竞争供应链中绿色成本分担博弈分析

Game analysis on green cost-sharing between competing supply chains

考虑零售商与制造商共同分担绿色成本的竞争供应链,研究了三种不同绿色成本分担模式的定价策略问题.基于博弈理论,建立了三种定价决策模型,并给出了相应的解析解.分析了三种不同绿色成本分担模式对产品零售价、绿色度以及供应链成员收益的影响.结果表明,竞争供应链对于绿色成本分担策略的选择不仅依赖于制造商分担绿色研发成本比例的大小,还与产品绿色竞争强度系数有关;其次,无论对方供应链是否采用绿色成本分担策略,只要制造商的绿色成本分担比例较大且绿色度竞争不是非常激烈时,采用成本分担策略就会有利于供应链成员获得更高的利润;随着供应链绿色度竞争的加强,成本分担策略的优势逐渐减弱.

Considering the competitive supply chain in which retailers and manufacturers share the green cost,the pricing strategies of three different green cost sharing modes are studied.Based on game theory,three pricing decision models are established,and the corresponding analytical solutions are obtained.The effects of three different green cost-sharing modes on the retail price,greenness and the benefits of supply chain members are analyzed.The results show that the selection of green cost sharing strategy for competitive supply chain not only depends on the proportion of manufacturers to share the green rd cost,but also depends on the product green competition intensity coefficient.Secondly,no matter whether the other supply chain adopts the green cost-sharing strategy or not,as long as the green cost sharing ratio of manufacturers is large and the green degree competition is not very fierce,the adoption of the cost sharing strategy will be conducive to the supply chain members obtaining higher profits.With the intensification of supply chain greenness competition,the advantage of cost sharing strategy is gradually weakened.
