消费者碳敏感情形下的竞争性低碳采购策略

在消费者碳敏感情形下,研究了竞争制造商的采购策略选择问题.建立了两个制造商分别选择生产策略或低碳采购策略的四种模型,得到了最优零售价格,批发价格以及供应链各方的最优利润.研究发现:较低的消费者碳敏感度会促使制造商均选择生产模式,使双方陷入囚徒困境.当消费者碳敏感度适中且碳减排差异较大时,制造商均选择低碳采购并实现Pareto改进.然而,当消费者碳敏感度较高且碳减排差异较小时,均衡策略为制造商选择差异化的生产模式,

Competitive low-carbon procurement strategy with carbon-sensitive consumers

In the presence of carbon-sensitive consumers, this paper studies the procurement strategies for two competitive manufacturers and develops four models in which the two manufacturers can choose the low-carbon procurement strategy or to make by themselves. With the study, we derive the optimal sales price and wholesale price, and the optimal profits for the respective supply chain partners. The studies show that those two manufacturers will choose the make regime and fall into the prisoner's dilemma when the carbon sensitivity level of the consumers is relatively low. While when the carbon sensitivity level is moderate for the consumers, those two manufacturers will adopt the low-carbon procurement strategy and attain Pareto optimality for the case where difference in the carbon emission is large for the two manufacturers. However, when the carbon sensitivity level of the consumers is high enough and the difference in carbon emission is small for the two manufacturers, the differentiated procurement strategy will be the equilibrium.
