供应链碳减排成本分摊的合作博弈研究

Research on Cooperative Game of Supply Chain Cost Sharing in Carbon Emission Reduction

绿色供应链的构建,可以让绿色发展的环保理念在地方政府或者企业实践的同时,促进改善环境生态,力助环保。在这样的大背景下,结合低碳环境,本文研究了由单一制造商和单一零售商组成的两级供应链碳减排成本分摊状况,分别计算出三种决策下的企业供应链利润期望值以及碳减排水平。本文利用合作博弈理论的契约模型,研究了绿色供应链中减少碳排放水平的成本分摊策略。在考虑消费者需求的不确定条件下,引入服从正态分布的需求误差变量,在计算中体现在利润期望值求极大值,对现存文献中直接求利润最大值的简单算法做出一定改进。如何在进行供应链碳减排成本合理分摊的同时,保持供应链协调,是本文试图解决的重要议题。

The construction of green supply chain may let the concept of environmental protection of green development be practiced in local governments or enterprises.Meanwhile,this may promote the improvement of environmental ecology and enhance environmental protection.Combining low carbon environment,this paper studies the cost sharing of carbon emission reduction in a two-stage supply chain consisting of a single manufacture and a single retailer under such background.This paper uses the contract model of cooperative game theory to study the cost sharing strategy of reducing carbon emission level in green supply chain.Considering the uncertainty of consumer demand,this paper introduces the demand error variable which obeys the normal distribution.The calculation is embodied in the maximization of profit expectation.Some improvements are made in the simple algorithm of direct maximization of profit in the existing literature.How to rationally share the cost of carbon emission reduction in supply chain while maintaining supply chain coordination is an important issue that this paper tries to solve.
