回收商互惠偏好下建筑废弃物资源利用供应链决策

Supply Chain Decision-making for Construction and Demolition Waste Resource Utilization Under Reciprocal Preferences of Recyclers

为揭示互惠偏好下建筑废弃物资源利用供应链中成员决策机制,基于逆向供应链理论、互惠偏好理论和消费者行为理论,运用Stackelberg博弈论方法构建模型并求解,进一步比较分析分散式决策和集中式决策下互惠偏好、消费者低碳偏好等相关因素对企业决策的影响。研究表明:在集中决策下,消费者低碳偏好的增加会降低建筑废弃物再制商和回收商的回收价格,而提高再制商碳减排水平;在分散决策下,当回收商互惠偏好程度较高时,再制商的利润显著提高而回收商的利润与效用均大幅度降低。研究结论为建筑废弃物资源利用供应链成员的策略选择提供依据。

To explore the decision-making of members in the supply chain of construction and demolition waste resource utilization under reciprocal preferences,a model is constructed and solved using the Stackelberg game theory approach,based on reverse supply chain theory,reciprocal preference theory,and consumer behavior theory.The impact of factors related to reciprocal preferences,and consumer low-carbon preferences on firm decisions under decentralized and centralized decision-making is analyzed.The results show that under centralized decision-making,increased low-carbon preferences of consumers reduces the recycling price of construction waste remanufacturers and recyclers,while increasing the carbon reduction level of remanufacturers.Under decentralized decision-making,when the reciprocal preference of recyclers is high,the profit of remanufacturers increases significantly,while the profit and utility of recyclers both decrease significantly.The findings provide the basis for strategy selection by members of the construction waste resource utilization supply chain.
