摘　　要：在碳交易机制的背景下,综合考虑消费者的低碳偏好性和废旧产品回收质量的不确定性,通过构建由制造商和零售商组成的Stackelberg博弈模型,研究回收质量与碳交易价格对产品定价、最优减排量及减排投资成本上限的影响。研究表明:市场规模越大,最优单位碳减排量越大;当废旧产品回收质量较低时,系统总利润随碳交易价格的升高而降低,当废旧产品回收质量较高时,系统总利润随碳交易价格的升高而升高,此时,零售商应采取薄利多回收的策略。最后,通过数值算例对主要参数进行灵敏度分析。In the context of the carbon trading mechanism,this paper considers the low carbon preference of consumers and the uncertainty of recycling quality of used products.By constructing a Stackelberg game model consisting of manufacturers and retailers,this paper studies the impact of recycling quality and carbon trading prices on product pricing,optimal emission reductions,and emission reduction investment cost caps.Research shows that the larger the market size,the greater the unit's carbon emission reduction.When the quality of waste product recycling is low,the total profit of the system decreases as the carbon transaction price increases.When the quality of waste product recycling is high,the total profit of the system increases with the increase of the carbon trading price.At this point,retailers should adopt a strategy of small profits recovery.Finally,the sensitivity analysis of the main parameters is carried out by numerical examples.
