基于碳配额交易的闭环供应链定价决策研究

Closed-loop supply chain pricing decision under carbon cap-and-trade system

文章引入了外生消费者偏好对新品和再造品进行区分,针对企业加入碳交易体系和不加入而接受超额惩罚2种情形建立模型,并运用二层规划方法对模型进行求解,通过数值仿真探究了不同排放配额、交易价格和惩罚价格对企业定价决策的影响。模型结果表明,虽然碳配额机制在一定程度上降低了企业利润并提高了产品售价,但是能够促使企业扩大回收力度、改变生产模式和降低二氧化碳排放,且碳限排政策相比于碳交易政策对企业排放约束更为直接有效,且更具稳定性。

In this paper, the exogenous consumer preference is introduced to classify new and remanu- factured products. Enterprises may join the carbon trading mechanism or not join and accept the punishment for exceeding quotas. According to the two situations, the models are built. The hi-level pro- gramming approach is used to solve the models. Through numerical simulation, the influence of dif- ferent emission quotas, trading prices and penalty prices on the pricing decisions of enterprises is ana- lyzed. The modeling results show that although the carbon quota mechanism reduces the profits of en- terprises and raises the selling price to some extent, it can promote the enterprises to enhance the re- cycling intensity, change the production mode and reduce carbon dioxide emissions. Compared with the carbon emission trading policy, the effect of the carbon emission restriction policy on the carbon e- mission constraint of enterprises is more direct, efficient and stable.
