This article uses a refined version of historical institutionalism to critically examine the complex interplay of forces that shape the health insurance reform trajectory in China since the mid-1980s, problems that plague the current multi-layered social medical insurance system and solutions to these problems. It shows that achieving universal health coverage (UHC) requires the government to ensure financing equity between urban and rural insured participants, access to affordable health care and the financial sustainability of medical insurance funds. Facing the challenges of rapidly aging population, the government implements a pilot scheme that integrates medical and nursing care for the elderly and a pilot long-term care insurance scheme for disabled elderly. It is expected that these two pilot schemes can provide better financial protection and quality of medical services for the elderly.
