  The medical insurance system refers to a mechanism through which a country or region collects, allocates, and utilizes medical insurance funds based on insurance principles to address residents' healthcare needs. It serves as an effective financing mechanism for public health initiatives, represents an advanced form within social insurance frameworks, and constitutes a widely adopted global model for managing healthcare expenditures.

  China's basic medical security system comprises the Basic Medical Insurance for Urban Employees, Basic Medical Insurance for Urban Residents, the New Rural Cooperative Medical Scheme, and the Urban-Rural Medical Assistance System. Since 1997, governmental efforts to strengthen the medical security framework have achieved breakthroughs, establishing the world's largest medical security system. However, challenges persist due to China's vast population and uneven regional economic development, including overall low coverage levels, significant disparities in benefits across populations, insufficient adaptability to mobility, and inadequate sustainability mechanisms.

  Simultaneously, medical security and healthcare services are intrinsically interconnected and mutually influential. Medical security functions must be realized through purchasing medical services, a process that simultaneously drives advancements in the healthcare sector. On one hand, the continuous refinement of the medical security system provides stable funding sources for national health. These funds ultimately translate into revenue for healthcare institutions via service procurement, offering sustained financial support for medical development. On the other hand, as representatives of insured populations, medical security agencies exercise oversight, impose constraints, and provide guidance to medical institutions during service procurement. This facilitates the formation of external checks-and-balances mechanisms, standardizes medical service delivery, and promotes healthcare system reforms and institutional management enhancements.
