Circular economy (CE) and sharing economy (SE) are much discussed concepts but potential links between them have not been examined systematically so far. The concepts’ popularity coupled with a lack of definitional consensus may hinder their potential to advance sustainability transitions. Hence, the first comparative bibliometric study of these two concepts was carried out. It was found that they share notable links in the fields of sustainability, business models, sustainable consumption and governance. Business model literature reveals links mostly in the realms of platform- and service-based activities. The field of SE has a strong consumer focus but, unlike CE, barely addressed rebound effects so far. Governance literature shows a general top-down dynamic driving CE, while SE is considered to be bottom-up. SE is conceptualized as a subset of CE which opens possibilities for mutual enrichment. The findings aim to provoke more dialogue between the CE and SE communities.

循环经济（CE）和共享经济（SE）是讨论最多的概念，但是到目前为止，尚未对它们之间的潜在联系进行系统的研究。这些概念的流行加上缺乏定义共识，可能会阻碍其推进可持续性转型的潜力。因此，对这两个概念进行了首次比较文献计量学研究。人们发现它们在可持续性，商业模式，可持续消费和治理领域有着显着的联系。商业模型文献揭示了主要在基于平台和服务的活动领域中的链接。SE领域以消费者为关注焦点，但与CE不同，到目前为止，其反弹效应几乎未得到解决。治理文献显示一般的自上而下的动态驱动CE，而SE被认为是自下而上的。SE被概念化为CE的子集，这为相互丰富提供了可能性。研究结果旨在激发CE和SE社区之间的更多对话。
