低碳供应链生态研发、合作促销与定价的微分博弈分析

Differential game analysis of ecological R&D, cooperative promotion and pricing in the low-carbon supply chain

针对低碳供应链研发、促销与定价问题,构建微分博弈模型.将产品低碳度和商誉作为状态变量,综合考虑价格和非价格因素对市场需求的多重影响,考察并比较不同决策下供应链的反馈均衡策略,结合数值模拟,对相关参数进行敏感性分析.研究发现:集中式决策可促使供应链实现经济绩效和环境绩效双赢;产品批发价对分散式决策下供应链均衡策略及利润产生重要且不同影响;两种决策下产品低碳度随时间单调变化,而商誉的变化却呈现多样性.

Aiming at solving the problem of RD, promotion and pricing in the low-carbon supply chain, a differential game model is constructed. Both the products＇ low-carbon degree and goodwill are used as state variables. Meanwhile, it is considered that the market demand is affected by multiple factors, including the low-carbon degree, the goodwill and the retail price. Then, the feedback equilibrium strategies under different decision situations are obtained and compared. Furthermore,the sensitivity analysis of related parameters is conducted by using the numerical simulation method. The results show that the economic performance and environment performance of the low-carbon supply chain can achieve ＂win-win＂ with the help of centralized decision. In decentralized decision, wholesale price has important but different influences on equilibrium strategies and profits. The products＇ low-carbon degree trajectory is monotonic while the goodwill trajectory shows changing diversity.
