考虑公平关切的自主减排低碳供应链决策研究

在碳减排约束下,通过对低碳供应链进行建模,借助数值实验,运用博弈论的方法研究产品碳系数和制造商公平关切行为对低碳供应链定价策略、碳减排水平、供应链各方利润以及供应链整体利润的影响.研究结果表明:1)集中式决策模式下,产品碳减排水平和供应链整体利润要高于分散式决策.制造商客观存在的公平关切属性会进一步降低产品碳减排水平和供应链整体利润,且随着制造商公平关切程度的增大,供应链各方成员以及供应链整体利润均会减小,但制造商利润所占供应链总利润的份额却在不断增大;2)三种不同供应链决策模式下,低碳产品零售价格、碳减排水平和供应链利润均会随着碳系数的增大而增大;3)碳减排投资成本分担契约的实施能够促进低碳产品零售价格降低,销量增加,从而能够有效地提高低碳供应链的整体效率.

Pricing and coordination decisions in autonomous reduction low-carbon supply chain with fairness concerns

With the constraint of carbon emission reduction, investigate how fairness and carbon coefficient may affect the retail price, the product carbon emission degree, and the profits of the manufacturer, the retailer, and the entire supply chain by establishing game theoretical models of a low-carbon supply chain. The results show that:1) both product carbon emission degree and supply chain profit in a centralized supply chain are higher than those in a decentralized supply chain, with manufacturer fairness concern, product carbon emission degree and supply chain profit will further reduce, and the manufacturer's behavior of fairness concerns is not only harmful to the retailer's profit and total channel profit, but also harmful to itself profit. Interestingly, although the manufacturer's profits are coming down, the relative share of manufacturer's profit in the total channel are rising; 2) in three different decision-making models, the retail price of low-carbon product, carbon emission degree and supply chain profit will increase with the increase of carbon coefficient; 3) carbon reduction investment cost sharing contract can contribute to the implementation of increasing demand of low-carbon products and decreasing retail price. Regardless of whether the manufacturer's fairness is concerned about or not, carbon reduction investment cost sharing contract could increase the overall efficiency of the supply chain and expand the supply chain profits.
