基于碳交易的闭环供应链碳减排与定价策略研究

Study on Carbon Reduction and Pricing of Closed-loop Supply Chain Based on Carbon Trading

在消费者对低碳产品存在偏好的碳交易市场中,研究两级闭环供应链中的减排与定价决策问题.对于制造商负责回收模式下的回收再制造过程,采用指数分布来刻画废旧产品质量水平的不确定性.假设新产品和再制造品存在竞争关系,建立制造商和零售商间的Stackelberg博弈模型,给出制造商确定减排投资和回收参考价格以及零售商决定两种产品的差别定价策略,通过算例分析回收产品的残值和碳交易价格对最优策略和供应链成员利润的影响.研究表明,为了获得利润最大,当碳交易的市场价格升高时,制造商应加大减排投资,且零售商应采取提高产品零售价的策略.

In the carbon trading market with consumers prefer low carbon products, the problem of carbon emission re- duction and pricing in the two echelon closed--loop supply chain is studied. For the remanufacturing under the manufacturer＇s responsibility for recycling, exponential distribution is adapted to describe the quality level of the waste products. Assures that there is competition between new products and remanufactured products, a Stackelberg game model between the manufacturer and the retailer is developed. The manufacturer decides the investment for carbon reduction and recovery price of reference, and the retailer decides discriminational price of the two products. A numerical example is given to formulate the optimal strategy , and the impact of salvage and carbon trading price on the optimal strategy is analyzed. It show that, to maximize the profits, when the carbon trading price increases, the manufacturer should increase investment in emissions, and the retailer should raise the retail price of the product.
