基于碳限额条件下供应链减排前后收益情况对比分析

Contrastive Analysis of Earnings before and after Supply Chain Emission Reduction Based on Carbon Emission Limits

在消费者对低碳产品具有偏好和政府对企业实施碳限额政策的条件下,通过单位产品碳排量的净化率将商品市场和碳交易市场联系起来,研究了由单一制造商和单一零售商构成的两级供应链中零售商决定最佳订货量,制造商决定批发价格和单位产品碳排量净化率的决策问题.研究发现只要制造商实施减排策略,就能使制造商的利润增加.零售商在不付出任何减排成本的情况下"搭便车"随之提高了利润,并对最优单位产品碳排量的净化率的选择进行了详细探讨.最后,通过数值分析验证了上述结论.

Under the condition that consumers have a preference of low-carbon products and the government implement the carbon emission limits policy on enterprises,this paper discusses the decision-making problem of the two-supply chain consisting of a single manufacturer and a single retailer. In this chain,the retailer decides the optimal order quantity while the manufacturer decides the wholesale price and unit product carbon emission rate. The study found that as long as the manufacturer implement emission reduction strategies,the profits can be increased,retailers＇ profits also can be improved without any cost of emission reduction. And then the selection of optimum purification rate of carbon emission per unit product is discussed in detail. Finally,the above conclusions are verified by numerical analysis.
