Circular ecosystems: Past, present, and future research directions

Abstract Circular ecosystems have become a buzz concept in the circular economy, but differing meanings and theoretical foundations limit knowledge consolidation. To address this gap, we undertook a systematic literature review of the circular ecosystems literature published from 2004 to 2025. We analyzed the state‐of‐the‐art using content analysis and science mapping techniques based on articles from Scopus, Web of Science, and Google Scholar databases. Prominent research trends include: (i) conceptualization of circular ecosystems, (ii) circular ecosystems and sustainability, (iii) roles and agency of actors, (iv) alignment in circular ecosystems, (v) value co‐creation in ecosystems, (vi) governance of ecosystems, (vii) theoretical roots, and (viii) enablers of circular ecosystems. Furthermore, we present the etymology and evolution of circular ecosystems and present a comprehensive definition of the concept. Finally, we propose future research directions on circular ecosystems.
