考虑消费者低碳偏好的两级供应链博弈分析

Game Analysis in a Two-echelon Supply Chain Under the Consumer's Low-carbon Preference

消费者是供应链的最终环节,也是关键的环节,从一定程度上影响供应链所有成员的行为。基于此建立的供应链中考虑消费者低碳偏好的两阶段动态博弈模型,表明不同决策机制下制造商的单位碳排放减少量对供应链成员决策的不同影响。消费者的低碳偏好会影响不同决策模式下的供应链的绩效,即两种决策机制下的碳减排水平相同,但集中决策下的收益和产量均高于分散决策情形;消费者低碳偏好增加或者减排成本影响因子下降,都将使得供应链各成员的利润增加,从而进一步促进企业投入更多的资源进行减排。

The consumer is the final link and the key link of supply chain, and it has great impact on the behavior of all the members on supply chain. The establishment of the two stage dynamic game model of supply chain management with consumer＇s low-carbon preference considers the influence of manufacturer＇s unit carbon emission reduction on the members of supply chain decision under the different decision-making mechanism. We find that low carbon consumer preferences affect supply chain performance under the different decision mode. Namely, there is the same carbon emissions level but the different returns and yields in the two kinds of decision-making mechanism. As consumers＇ environmental awareness increases or the cost factor relat- ed to eco-friendly production and operations decreases, retailers and manufacturers with low carbon operations will benefit, and further promote enterprise to invest more resources for emissions reductions.
