In order to investigate the issues of the recycling and remanufacturing of construction and demolition waste (C&D waste), this paper develops a closed-loop supply chain (CLSC) consisting of a manufacturer, a retailer, and a recycler, considering both the retailer's fairness concern psychology and governmental regulations. Four mathematical models are developed for the calculations, and the models are solved through game theory. In both the decentralized and centralized scenarios, the members' strategies are discussed and the optimal values of decision variables are determined. A numerical study is carried out for sensitivity analyses to verify the accuracy of the theoretical conclusions. The results reveal that retailer fairness concerns lead to a decrease in the wholesale price of building materials and negatively affect manufacturers' profits. Additionally, governmental regulations can effectively increase the recycling amount and improve the utilization rate of C&D waste, and promote a virtuous cycle of the recycling and remanufacturing of C&D waste.
为了研究建筑和拆除废物（C&D 废物）的回收和再制造问题，本文建立了一个由制造商、零售商和回收商组成的闭环供应链（CLSC），同时考虑了零售商的公平关切心理和政府法规。本文开发了四个数学模型进行计算，并通过博弈论求解了这些模型。在分散和集中两种情况下，讨论了成员的策略，并确定了决策变量的最优值。进行了数值研究以进行敏感性分析，以验证理论结论的准确性。结果表明，零售商的公平关切会导致建筑材料的批发价格下降，并对制造商的利润产生负面影响。此外，政府法规可以有效地增加回收量，提高 C&D 废物的利用率，促进 C&D 废物回收和再制造的良性循环。
