With the growing number of semi-disabled and disabled elderly people in China, the demand for long-term care services is is growing faster. With the service conditions of “maintenance integration”, the elderly with disabilities are increasingly favored by the combination of medical and nursing institutions. From the perspective of supply and demand of long-term care services, this paper explores the current situation of long-term care service supply in medical and nursing institutions in Hohhot and the demand for long-term care services of disabled elderly residents. Findings indicate that there is a contradiction between the supply and demand of long-term care services in medical and nursing institutions due to the lack of government guidance in funding investment, unclear positioning of medical and nursing institutions, lack of professional nursing personnel and imperfect long-term care security system. It is suggested to resolve the contradiction between supply and demand of long-term care services from optimizing resource allocation, perfecting the needs assessment system of disabled elderly, cultivating nursing talents, and perfecting the long-term care security system.
