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

摘S要：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,随后采用修正投影算法,仿真分析了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,消费者低碳偏好较高时,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。

Research on Closed-loop Supply Chain Network Equilibrium decision Considering Consumers" Low Carbon Preference under Government Subsidy

Using the variational inequality and equilibrium theory,a closed-loop supply chain network equilibrium model considering consumers" low-carbon preference based on low-carbon degree was established. The modified projection algorithm was used to explore the influence of government subsidy and consumers" low-carbon preference on the equilibrium decisions. Results show that subsidy that government give remanufactured product purchasers and consumers" low-carbon preferences are both conducive to carry out remanufacturing activities. But lower government subsidy harms consumers" interests while higher consumers" low-carbon preference leads remanufactured products to further cannibalizate new products in the market; government subsidy may cause manufacturers and consumers to share the subsidy, thereby improving the economic performance of closed-loop supply chain network, but worsening environmental performance; when consumers" low-carbon preference is lower, network and manufacturers" economic performance are better, but environmental performance worse; when consumers" low-carbon preference is higher, the network and manufacturers can obtain more environmental benefits, but need to give up part of the economic benefits.
