Under the background of the global transformation of primary health care (PHC) systems, the patient-centered medical home (PCMH) model, with its core philosophy of "people-centered, integrated, continuous, and team-based care", has emerged as a significant paradigm for enhancing PHC service quality. In China, community health services are undergoing a critical transition from a disease-treatment focus towards health management. The deepening implementation of systems such as contracted family doctor services and hierarchical diagnosis and treatment provides fertile ground for adopting and integrating PCMH concepts. This paper systematically reviews the core elements of PCMH and international practical experiences. By comparing these with the current state of China's community health service system, it identifies structural discrepancies and transformational challenges across six key dimensions: payment incentives, information technology, human resources, service culture, organizational management, and systemic collaboration. Corresponding synergistic reform strategies are proposed. Building on this analysis, the study constructs a progressive, four-stage implementation pathway comprising "organizational preparation, process re-engineering, comprehensive scaling, and continuous improvement". The aim is to provide a reference that combines theoretical systematicity and practical operability, thereby to promote the high-quality development of China's contracted family doctor services with the emphasis shifting from "quantity of contracts" to "quality of service", and from "fragmented" to "integrated" care.
