Purpose The aim of this review is to test the link between servitisation and circular economy (CE) by synthesising the effect of product-service systems (PSS) on supply chain circularity. Design/methodology/approach Following a systematic literature review methodology, the study identified 67 studies and synthesised them using content analysis. Findings – A conceptual model is developed illustrating how PSS business models impact supply chain circularity through increased product longevity, closure of resource loops, and resource efficiency. It also identifies six contextual factors affecting the implementation of supply chain circularity including: 1) Economic attractiveness of supply chain circularity; 2) Firm sustainability strategy; 3) Policy and societal environment; 4) Product category; 5) Supply chain relationships; 6) Technology. Research limitations/implications – The conceptual model proposes that supply chain circularity increases with servitisation. It also proposes that the main circularity effect stems from increased product longevity, followed by closed resource loops, and finally resource efficiency. The model is deduced from the literature by using secondary data. Practical implications – The review provides practitioners with a framework to increase supply chain circularity through PSS business models. It also gives insight into the various contextual factors that may affect how a manufacturer’s servitisation strategy contributes to supply chain circularity. Originality/value – This review contributes to the understanding of the relationship between servitisation and supply chain circularity by synthesising the different effects that exist. Moreover, it creates new knowledge by identifying a range of contextual factors affecting the relationship between PSS and supply chain circularity.

服务化如何影响供应链的循环性？–系统的文献综述

目的这篇综述的目的是通过综合产品服务体系（PSS）对供应链循环性的影响来检验服务化与循环经济（CE）之间的联系。设计/方法/方法按照系统的文献综述方法，该研究确定了67项研究，并使用含量分析进行了综合。结果–开发了一个概念模型，说明PSS业务模型如何通过提高产品寿命，闭合资源循环和资源效率来影响供应链的循环性。它还确定了影响供应链循环性实施的六个环境因素，包括：1）供应链循环性的经济吸引力；2）企业可持续发展战略；3）政策和社会环境；4）产品类别；5）供应链关系；6）技术。研究的局限性/意义–概念模型提出，随着服务化，供应链的循环性会增加。它还提出，主要的循环效应是由于产品寿命的延长，紧随其后的资源循环以及最终的资源效率。该模型是通过使用辅助数据从文献中推导出来的。实际意义–该评估为从业人员提供了一个框架，可通过PSS业务模型来提高供应链的循环性。它还洞悉了可能影响制造商的服务化策略如何促进供应链循环性的各种环境因素。独创性/价值–该综述通过综合现有的不同影响，有助于理解服务化与供应链循环性之间的关系。此外，
