It is also the inexorable trend of the development of the basic medical insurance in China. It has been more than ten years since the integration of the three kinds of medical insurances was implemented in Dongguan. The new system has been running smoothly and is achieving remarkable success.

The integration of the basic medical insurances in China should be realized gradually under the principles of suiting measures to local conditions, making differential sharing of financial subsidies, paying attention to fairness and conforming to“Pareto improvement”, by transiting from the integration of the two kinds of basic medical insurances into the integration of the three basic medical insurances and gradually achieving the overall planning at the provincial level, a unified national health insurance system will finally be established.
