Are Ecosystems the Missing Link in Circular Transitions? Insights From a Comprehensive Literature Analysis
通过主题建模和系统综述分析66篇论文，揭示了循环生态系统的三大主题：循环商业模式与创新、政策与利益相关者治理、实施与转型，并指出未探索领域，为管理者提供融入循环生态系统的指导。
ABSTRACT Although recent literature on the circular economy ( CE ) has highlighted the important role of ecosystems, there is still limited understanding of the main themes that characterize circular ecosystems. This study addresses this gap by combining a comprehensive topic modeling analysis employing latent Dirichlet allocation (LDA) with a systematic literature review of 66 articles focused on circular ecosystems. The main results reveal that circular ecosystems have often been analyzed through the lens of (i) circular business models and ecosystem innovation, (ii) CE policies and stakeholder governance, and (iii) implementation and transition to CE . Furthermore, based on this study's findings, topics that have not yet been explored in this area are identified, and a research agenda is suggested. The results of this study also underscore key themes in the relationship between CE and ecosystems and provide managers with guidance on better integrating their businesses into ecosystems aligned with circularity objectives.
