Abstract

The accurate understanding and measurement of circularity in purchasing and supply management is crucial for organisations aiming to enhance sustainability, reduce costs, and comply with regulations. However, existing circular economy indicators do not account for all circularity dimensions (i.e., C1-monetary, C2-energy and environment, C3-material, C4-temporal and C5-efficiency) and neglect key actors (i.e., collectors, recyclers, manufacturers, users) in the circular supply chain. Consequently, this results in biased decision-making when selecting supply chain partners, hindering the circular economy's progress. This study investigates the effectiveness of circular economy indicators and their constituent circular economy items at the circular supply chain level to better evaluate circular economy accomplishments. Out of the 63 circular economy indicators and 23 circular economy items identified, only three evaluate all five circularity dimensions, while nearly 40 percent fail to consider critical actors within the circular supply chain. Drawing on stakeholder theory, this study proposes a framework for developing an effective circular economy indicator. The proposed framework is validated through a hybrid approach, beginning with the fuzzy analytical hierarchy process to ascertain the weights of circular economy items, followed by the fuzzy technique of order preference similarity to the ideal solution to rank recycling alternatives using the determined weights, and culminating with the linear programming to optimise the circularity based on the established rankings. This research emphasises the importance of covering all circularity dimensions and targeting all circular supply chain actors in aligning the goals of different entities with the broader objectives of the circular economy. It is the first study to provide guidance on developing circular economy indicators and evaluating circular economy performance from a circular supply chain perspective, serving as a solid foundation to achieve circular economy agendas. It affords purchasing and supply practitioners the opportunity to augment decision-making processes, optimise sustainability efforts, and bolster supply chain regulatory adherence and governance.

重新审视循环经济指标:循环供应链视角
在采购和供应管理中准确理解和衡量循环性,对于旨在提高可持续性、降低成本和遵守法规的组织来说至关重要。然而,现有的循环经济指标并没有考虑到所有的循环维度(即 C1-货币、C2-能源和环境、C3-材料、C4-时间和 C5-效率),并且忽视了循环供应链中的关键参与者(即收集者、回收者、制造商和用户)。因此,这会导致在选择供应链合作伙伴时出现决策偏差,阻碍循环经济的发展。本研究调查了循环经济指标及其组成的循环经济项目在循环供应链层面的有效性,以更好地评估循环经济的成就。在已确定的 63 个循环经济指标和 23 个循环经济项目中,只有 3 个指标对所有五个循环维度进行了评估,而近 40% 的指标没有考虑到循环供应链中的关键参与者。本研究借鉴利益相关者理论,提出了一个制定有效循环经济指标的框架。首先采用模糊层次分析法确定循环经济项目的权重,然后采用与理想解决方案相似的模糊排序偏好技术,利用确定的权重对循环备选方案进行排序,最后采用线性规划法,根据确定的排序优化循环性。这项研究强调,在将不同实体的目标与更广泛的循环经济目标相统一时,必须涵盖所有循环性维度,并以所有循环供应链参与者为目标。这是第一项从循环供应链角度为制定循环经济指标和评估循环经济绩效提供指导的研究,为实现循环经济议程奠定了坚实的基础。它为采购和供应从业人员提供了加强决策过程、优化可持续发展工作以及加强供应链监管和治理的机会。

期刊介绍: The mission of the Journal of Purchasing & Supply Management is to publish original, high-quality research within the field of purchasing and supply management (PSM). Articles should have a significant impact on PSM theory and practice. The Journal ensures that high quality research is collected and disseminated widely to both academics and practitioners, and provides a forum for debate. It covers all subjects relating to the purchase and supply of goods and services in industry, commerce, local, national, and regional government, health and transportation.
