Abstract: In the context of energy conservation and emission reduction, the low carbon production of manufacturers and the publicity competition of retailers are considered. The carbon emission reduction and goodwill are taken as state variables, to study the dynamic optimization and coordination of supply chain by means of differential game. With regards to the double marginalization effect, the supply chain is coordinated by introducing cost sharing contract. The research shows that after the introduction of contract, the retailers’ low-carbon publicity efforts, low-carbon goodwill and demand increase, and the supply chain profits basically reach the level of centralized decision-making. With the growing level of competition, the market demand upgrades, the manufacturer’s profit increases, and the overall profit of the supply chain rises, which inspires the supply chain enterprises to create a benign competition environment and form a benign competition mechanism in the decision-making process.

Key words: competition, goodwill of low-carbon, differential games, dynamic optimization, coordination

摘要： 在节能减排背景下考虑制造商低碳生产、零售商宣传竞争的情形,将碳减排量以及商誉作为状态变量,借助微分博弈研究供应链动态优化与协调问题。针对双重边际化效应,通过引入成本共担契约对供应链进行协调。研究表明,引入契约后零售商处的低碳宣传努力水平提高、低碳商誉提升、需求量增加,供应链利润基本达到集中决策水平;随着竞争程度的增加,市场需求量提高,制造商利润增加,供应链整体利润提高,启发供应链企业在决策过程中创造良性竞争环境、形成良性竞争机制。
