碳标签制度下产品碳足迹与定价决策及协调

Product carbon footprint and pricing decisions and coordination under carbon labelling system

基于供应链视角研究了碳标签制度下制造商和零售商的产品碳足迹和价格决策以及协调问题.通过建立集中式和分散式决策模型,分别得出了两种决策方式下制造商和零售商的最优策略组合,并分析了消费者环境意识对产品碳足迹和销售价格的影响.结果表明,碳标签制度下产品的碳足迹和销售价格不仅依赖于消费者的环境意识水平,还与其初始碳足迹以及供应链的决策方式有关.然后,引入两部定价合同实现了碳标签制度下供应链系统的完美协调.最后,通过算例分析验证了相应的结论.

This paper studies the products＇ carbon footprints and price decisions for the manufacturer and retailer,as well as the coordination problems under carbon labelling from the perspective of the supply chain.Both centralized and decentralized decision-making models are established,the combinations of the optimal strategies for the manufacturer and retailer are obtained respectively under the two decision-making styles,and the impacts of consumer environmental awareness on product carbon footprints and prices are also analyzed.The results show that products＇ carbon footprint sand prices under carbon labelling not only depend on the level of consumer environmental awareness,but also relate to the initial carbon footprints of the product and the choices of decision-making styles of the supply chain.Afterwards,the two-part pricing contract is introduced to coordinate the supply chain system with carbon labelling.Finally,a numerical example is provided to confirm the correctness of the conclusions.
