针对消费者低碳偏好和第三方物流企业(Third-Party Logistics,3PL)对供应链决策造成重大影响的现象,为提高供应链整体的效率,提出了采用支撑收益共享契约( Spanning Revenue-Sharing Contract, SRS)来实现供应链协调;基于消费者低碳偏好构建了制造商、3PL和零售商的4个博弈模型,通过求解,得到了不同情形下供应链博弈的均衡解,研究了3PL提供物流服务和零售商自营物流下消费者低碳偏好对实际碳排放量的影响;通过数值仿真探讨了不同决策情形下消费者环保意识对实际碳排放量、产品需求、供应 链利润和供应链协调的影响。进一步分析发现:初始碳排放量较低时,消费者环保意识的增强可以降低单位产品的实际碳排放量;初始碳排放量较高时,实际碳排放量随着消费者环保意识的增强呈现先降低、后提高的态势。在一定的条件下,无论初始碳排放量高还是低,3PL提供物流服务可以提高制造商和供应链整体的 利润。SRS契约可以有效协调供应链,实现供应链全体成员的帕累托改进。
As consumers’low-carbon preference and third-party logistics (3PL) have a significant impact on supply chain decision-making, Spanning Revenue-Sharing Contract is proposed to achieve supply chain coordination. Based on consumers’low-carbon preference, four game models of manufacturer, 3PL and retailer are constructed. By solving the problem, the equilibrium solution of supply chain game under different situations is obtained, and the influence of consumers’low carbon preference on actual carbon emissions under 3PL logistics service and retailer self-logistics is studied. The effects of consumers’environmental awareness on actual carbon emissions, product demand, supply chain profit and supply chain coordination under different decision-making situations are discussed by numerical simulation. Further analysis shows that when the initial carbon emission is low, the enhancement of consumers’ environmental awareness can reduce the actual carbon emission per unit product. However, when the initial carbon emission is high, the actual carbon emission first decreases and then increases with the enhancement of consumers’ environmental awareness. Under certain conditions, whether the initial carbon emissions are high or low, 3PL can improve the profits of manufacturers and the whole supply chain by providing logistics services. SRS contract can effectively coordinate the supply chain and achieve Pareto improvement of the supply chain for all members.
