近年来，随着世界范围内环境问题的凸显和资源的枯竭，人们开始重视和考虑废 旧产品的资源再生利用问题。然而迄今为止的大多数研究都局限于电子产品和机械制 造等几个行业之内，日常消费领域的服装纺织品行业却少有人关注。我国人口众多， 服装纺织品年消耗量大，这些服装纺织品经过几年的短暂使用后，大都废弃，回收使 用率不高。针对这些问题，本文将闭环供应链理论和消费者效用理论运用到废旧服装 纺织品回收利用过程中，建立了该领域闭环供应链模型。然而，闭环供应链的建立只 是基础，影响整个闭环供应链效率的重要因素是该系统的协同度。只有各个节点企业 之间相互协同合作，打破供应商、制造商、零售商、第三方、消费者等之间的壁垒， 才能协调统一的实现闭环供应链规模效益。在闭环供应链协同研究方面，采用多案例 研究法，从服装行业典型企业着手，梳理服装纺织品闭环供应链的建立过程，提取闭 环供应链协同五要素，构建该领域协同框架。在该框架下，对协同因素的评价内容进 行层层细分，最后运用层次分析法进行量化打分，从而为评价闭环供应链的协同效率 开辟路径，为企业之间更好实现的协同合作提供参考。 关键词：闭环供应链 服装纺织品 协同 消费者效用 Abstract In recent years, with the worldwide environmental problems and the depletion of resources, people begin to pay attention to and consider the recycling of waste products. However, up to now, most of the researches are limited to the electronic products and machinery manufacturing industries, and few people pay attention to the clothing and textile industry in the field of daily consumption. China has a large population, and the annual consumption of clothing textiles is large. After several years of short-term use, most of these clothing textiles are abandoned, and the recycling rate is not high. In view of these problems, this paper applies the closed-loop supply chain theory and consumer utility theory to the recycling process of waste clothing textiles, and establishes the closed-loop supply chain model in this field. However, the establishment of the closed-loop supply chain is only the foundation, and the important factor that affects the efficiency of the whole closed-loop supply chain is the coordination degree of the system. Only when the enterprises of each node cooperate with each other and break the barriers among suppliers, manufacturers, retailers, third parties, consumers, etc., can the scale benefit of closed-loop supply chain be realized in a coordinated and unified way. In the research of closed-loop supply chain collaboration, this paper uses the multi case study method, starting from the typical enterprises in the clothing industry, combs the establishment process of closed-loop supply chain of clothing and textiles, extracts the five elements of closed-loop supply chain collaboration, and constructs the collaborative framework in this field. In this framework, the evaluation contents of collaborative factors are subdivided layer by layer, and finally the AHP is used to quantify the score, so as to open up a path for the evaluation of collaborative efficiency of closed-loop supply chain, and provide a reference for better collaborative cooperation between enterprises.。。。。。。以下内容略
