Abstract: In the new period, the Chinese health security system has entered a stage of high-quality development. The benefits adjustment and payment of medical security not only have the foundation of universal participation and the opportunity of deepening reform, but also face the pressure of rigid growth and complex social challenges. However, the rigid growth pressure of welfare and rapid social changes pose challenges, which requires not only the dynamic adjustment of health insurance benefits and the compound reform of the payment system, but also the coordination of these two elements. Therefore, it's necessary to regard the reconstruction of equilibrium as an important task in deepening the health insurance reform. Additionally, the systems face such status and problems as gradual increasing but unequal benefits, large balances but unbalanced structure fund, advancing but improper linkage payment reform. Due to this, the deepening development of the health secarity system need the integration of institution, management, operation, resource, and governance.
