政府补贴下考虑消费者低碳偏好的闭环供应链网络均衡决策

Equilibrium Decision of Closed-loop Supply Chain Network Considering Consumers’ Low-carbon Preference Under Government Subsidy

考虑基于产品低碳度的消费者低碳偏好,运用变分不等式和均衡理论构建政府补贴下的闭环供应链网络均衡决策模型,采用修正投影算法仿真分析政府补贴和消费者低碳偏好对闭环供应链网络均衡决策的影响。研究结果表明:政府补贴与消费者低碳偏好均有助于促进企业回收再制造,但较低的政府补贴会损害消费者利益,较高的消费者低碳偏好增长了再制造产品对新产品的挤兑效应;政府补贴再制造产品消费者有可能导致制造商与消费者共享补贴,提升闭环供应链网络的经济绩效,但环境绩效降低;消费者低碳偏好较低时,网络及制造商经济绩效较高但环境绩效较低,反之网络及制造商可获得较高的环境效益但需要以放弃部分经济效益为前提。

In this paper, based on the low carbon preference of consumers, the equilibrium decision model of closedloop supply chain network under government subsidy is constructed by using variation inequality and equilibrium theory, and the influence of government subsidy and consumer low carbon preference on the equilibrium decision of closed-loop supply chain network is simulated and analyzed by using modified projection algorithm. The results show that both government subsidy and consumer low carbon preference help to promote enterprise recycling and remanufacturing, but the lower government subsidy will harm the interests of consumers, and the higher consumer low carbon preference will increase the run effect of remanufactured products on new products;government subsidies for consumers buying remanufactured products may lead manufacturers to share subsidies with consumers and improve the economic performance of closed-loop supply chain networks, but the environmental performance is reduced;when consumers* low carbon preference is low, the economic performance of the network and manufacturers is higher but the environmental performance is lower, on the contrary, the network and manufacturers can obtain higher environmental benefits but need to give up some economic benefits.
