基于渠道竞争的双渠道供应链低碳协调策略

针对由一个制造商和一个零售商构成的双渠道供应链,将渠道竞争和产品的低碳性能引入消费者的非线性需求中,通过构建制造商为主导者的Stackelberg博弈模型,对比分析了分散决策和集中决策下的最优定价、碳排放水平和成员利润,并采用价格折扣-成本分摊契约实现了供应链的协调。研究结果表明:在分散决策和集中决策两种情况下,渠道竞争程度的增加均会造成碳排放水平、供应链利润和消费者效用的降低;集中决策下的直销价格大于分散决策下的直销价格,集中决策下的零售价格小于分散决策下的零售价格。最后通过算例验证了以上结论和协调机制的有效性。

Low-Carbon Coordination Strategy of Dual-channel Supply Chain Based on Channel Competition

In this paper,we studied a dual-channel supply chain consisting of a manufacturer and a retailer.By introducing channel competition and product low-carbon performance into consumer non-linear demand and constructing a Stackelberg game model with the manufacturer as the leader,we analyzed comparatively the optimal pricing,carbon emissions level and member revenue under decentralized and centralized decision-making respectively,and used a price discount-cost sharing contract to coordinate the supply chain.The result shows that in both decentralized and centralized decision-making scenarios,increase in channel competition will reduce carbon emissions,supply chain revenue and consumer utility;the direct selling price under centralized decision-making is greater than that under decentralized decision-making,while the opposite is true for the retail price.At the end,a numerical example is used to verify the effectiveness of the above conclusions and coordination mechanism.
