This conceptual paper examines the influence of organizational culture, sustainable leadership, and cross-sectoral collaboration on circular economy (CE) performance, and explore the role of circular supply chain capability (CSCC) in enacting this relationship. Drawing on the Dynamic Capabilities View (DCV) and Stakeholder theory, the paper proposes that organizational culture provides the foundation for environmental adaptability, sustainable leadership enables strategic transformation, and collaboration broadens resource access and operational synergy, all contributing to the development of CSCC. Through a comprehensive review of literature, the study presents a conceptual framework that positions CSCC as a critical dynamic capability linking internal and relational enablers to circular economy performance. This paper addresses existing gaps by integrating organizational and relational drivers into a unified model and offers a basis for empirical validation in future research.
