循环经济（CE）和关系思维越来越被认为是资源可持续性的有前途的解决方案。CE旨在通过减少、再用、循环和回收材料来设计废物，而Nexus方法则关注资源之间的相互联系，以尽量减少废物和低效率。这两个概念一直在各自发展，分析其关系的学术工作有限。本文基于2004年至2020年的学术出版物，采用文献计量分析和主题综合等混合方法，对循环经济与关系方法之间的关系进行了系统的研究。我们的定量文献计量学分析表明，在7956篇循环经济和5795篇nexus论文中，明确提到这两个概念的学术文献占每种文献的不到1%。尽管如此，两篇文献之间的最常见词汇（50%-71%）以及最相关来源（54%-56%）存在相当大的重叠。对与这两个概念有关的文件进行的详细的定性分析也支持这两个概念之间存在着密切的关系。从这些分析中，我们开发了一个新的综合概念之间的关系，循环经济和关系的方法。我们的结论是，有很好的证据，一个三层的层次关系：“交叉”，“相互关系”和“相互依赖”，我们详细讨论。最后，强调综合方法的重要性，我们提出了一个新的概念框架，它结合了循环经济和关系的方法，这有助于操作关系的思维，一方面，并收敛循环经济对环境的可持续性。因此，该框架解决了这些概念的两个已知挑战。然而，虽然我们的综合框架有助于循环经济和关系方法的概念发展，但需要进一步研究，以突出和促进它们在实践中的相互关系和相互依存关系。
Circular Economy (CE) and nexus thinking are increasingly considered as promising solutions for resource sustainability. While CE aims to design out waste through reducing, reusing, recycling and recovery of materials, the Nexus approach is interested to minimise waste and inefficiencies by focusing on the interlinkages between resources. Both concepts have been evolving separately with limited academic work to analyse their relationship. The aim of this systematic review, based on academic publications from 2004 to 2020, is to scrutinise the relationship between the circular economy and the nexus approach by adopting a mixed methods research design including bibliometric analysis and thematic synthesis. Our quantitative bibliometric analysis shows that, out of 7956 circular economy and 5795 nexus papers, academic documents explicitly mentioning both concepts account for less than 1% of each literature. Nonetheless, there is considerable overlap in most frequent words (50%–71%) as well as the most relevant sources (54%–56%) between both literatures. A detailed qualitative analysis of the documents relevant to both concepts also supports the existence of a close relationship between both concepts. From these analyses, we develop a new integrative conceptualization of the relationship between circular economy and the nexus approach. We conclude that there is good evidence for a three-tiered hierarchical relationship: ‘intersection’, ‘interrelation’ and ‘interdependence’, which we discuss in detail. Finally, emphasising on the importance of an integrated approach, we propose a novel conceptual framework which combines circular economy and nexus approaches, which helps to operationalise nexus thinking on the one hand, and to converge the circular economy towards environmental sustainability on the other hand. As such, the framework addresses two known challenges of the concepts. However, whilst our integrated framework contributes to the conceptual development of both circular economy and the nexus approach, further research is required to highlight and facilitate their interrelation and interdependence in practice.
