碳限额约束下考虑碳税的随机需求型闭环供应链网络均衡决策

Equilibrium Decision Research of The Stochastic Closed-loop Supply Chain Network with Cap Constraints and Carbon Tax Policy

摘要:

在碳限额约束下，考虑碳税政策，研究了由多个制造商、多个零售商、多个随机需求市场组成的供应链网络均衡决策问题。利用均衡理论和变分不等式研究工具，描述网络中各层决策者的竞争行为，给出各层均衡及网络均衡的条件，构建了碳限额约束下考虑碳税政策的随机需求型闭环供应链网络均衡决策模型。研究表明：网络内生的最优碳税保证了均衡状态下制造商的碳排放量没有超过政府规定的限额；当政府放宽对闭环供应链网络中企业的碳限额限制时，制造商采取提高回收价格增加回收量以及降低批发价提高产品批发量的方式，提高其利润，此时其碳排放量也在增加，这说明企业环境绩效与经济绩效存在着冲突，为了实现一定的环境目标需要放弃部分经济利益。

Abstract:

This paper studies the problem consisting of multiple manufacturers, multiple retailers, multiple random market demand supply chain network equilibrium decision based on carbon cap constraints, consider the carbon tax policy. We use the equilibrium theory and variational inequality research tools, describe the competitive behavior of each layer in the decision network, give each layer equilibrium and network equilibrium conditions, construct the stochastic demand closed-loop supply chain network equilibrium model with cap constraints and carbon tax policy. Research shows that: the optimal carbon tax in the network to ensure that there is no carbon emissions the manufacturer's equilibrium exceed the government's limit; when the government relaxed on the carbon limits the closed-loop supply chain in the network, the manufacturers take the increase in the cost of recycling to increase the recovery amount and lower wholesale price increase products wholesale volume, improve the profit, the carbon emissions are also increasing, which indicates that the company's environmental and economic performance of the existence of the conflict, in order to achieve certain environmental goals need to give up part of economic interests.
