Application Obstacles and Countermeasures of Circular Supply Chain in Enterprises —— Taking Mobile Phone Industry as an Example

Against the backdrop of increasing global resource consumption rates and growing environmental pressures, the limitations of the traditional linear economic model in advancing sustainable development have become increasingly apparent. In view of this, this study focuses on the mobile phone industry, thoroughly analyses the key obstacles faced in the practice of the circular supply chain in this industry, and explores the corresponding solutions. This study employs a mixed-method approach combining literature review and case analysis, and after careful exploration, identifies four core challenges in the process of building a circular supply chain for mobile communication equipment, namely, technical bottlenecks, economic challenges, consumer barriers and institutional environment constraints. In response to these challenges, this study puts forward highly operable suggestions from four key dimensions: technological innovation, business model innovation, consumer incentive and policy coordination. These suggestions aim to provide a reference framework with both theoretical depth and practical significance for the green transformation of enterprises.
