基于消费者低碳偏好的供应链碳减排策略

Carbon emission reduction strategy of supply chain with consumer low-carbon preference

针对一个占主导地位的零售商和两个制造商(名牌产品和普通产品制造商)组成的二级供应链,考虑制造商之间的定价顺序和低碳偏好消费者对普通产品的接受度,分别构建普通产品制造商采用或不采用减排技术情景下的收益模型,得出各情景下最优零售价格和收益。研究发现:零售商选择销售哪种产品与顾客对普通产品的接受度有关;普通产品制造商的减排策略主要取决于减排成本。在相同减排策略下,若顾客对普通产品接受度较大,制造商同时定价时产品的最优零售价小于等于不同时定价时产品的最优零售价,而同时定价时制造商的最优收益大于等于不同时定价时的最优收益,因此两个制造商应同时定价以获得更大的收益。

For a two-stage supply chain with one dominant retailer and two manufacturers(a famous-brand product manufacturer and an ordinary product manufacturer),considering the pricing sequence of two manufacturers and the acceptance of the ordinary product by consumers with low-carbon preference,the profit models under two conditions of the ordinary product manufacturer adopting or not adopting the emission reduction technology are constructed,and the optimal retail prices and profits under two conditions are obtained.It is found that,which product selected to sell by the retailer is related to the customer’s acceptance of the ordinary product;the emission reduction strategy of the ordinary product manufacturer is largely dependent on the emission reduction cost.In the same emission reduction strategy,if the customer’s acceptance of the ordinary product is bigger,the optimal retail prices of two products when two manufacturers pricing at the same time are no more than those when two manufacturers pricing at different times,and the optimal profits when two manufacturers pricing at the same time are no less than those when two manufacturers pricing at different times.Therefore,two manufacturers should price products at the same time for greater profits.
