借助微分博弈研究由单个制造商与两个零售商组成的供应链系统中长期联合减排和低碳宣传的问题.在消费者需求受产品减排量和零售商低碳宣传努力影响的情况下,构建了3种微分博弈模型.研究发现,在一定条件下,成本分担契约可以实现制造商和零售商利润的Pareto改善,而且处于稳定状态时,随着竞争强度的增加,制造商和整个供应链系统的利润逐渐上升,零售商的利润逐渐下降.最后,通过算例对模型进行了分析. Using the differential game to study the issue of long-term combined emission reduction and low-carbon publicity in a supply chain system consisting of a single manufacturer and two retailers.When consumer demand is affected by product emission reductions and low-carbon advocacy efforts by retailers , And builds three kinds of differential game models.The study finds that under certain conditions, cost-sharing contract can achieve the improvement of Pareto profits of manufacturers and retailers, and in the steady state, as the intensity of competition increases, the manufacturer and the entire supply The profits of the chain system gradually increased, and the profits of the retailers decreased gradually.Finally, the model was analyzed through a case study.
