供应链角度的碳减排问题受到了广泛的关注.在考虑消费者的低碳偏好对市场需求影响的基础上,建立了三种不同的契约模型,对供应链系统中制造商和零售商的联合减排机制及供应链利润协调问题开展了研究.分析结果表明,约束批发价格的成本分摊契约可以实现供应链利润的协调,并在一定条件下其减排效果最好:而批发价格契约和成本分摊契约不能实现供应链利润的协调,其中成本分摊契约在满足一定条件时其产品的碳减排水平最高.
Carbon reduction from the the perspective of supply chains has received widespread attention. Con- sidering consumers' low-carbon preference that affects the market demand for a product, this paper establishes three different contract models, and studies the joint carbon emission reduction mechanism between a manu- facturer and a retailer in the supply chain system and the profit coordination of the supply chain. The analysis shows that the cost sharing contract under constraint wholesale price can coordinate the supply chain's profit effectively and results in the best carbon emission reduction under certain conditions, that the wholesale price contract and the cost sharing contract cannot coordinate the supply chain's profit, and that the cost sharing contract can result in the highest level of carbon emission reduction for a product when certain conditions are met.
