ABSTRACT
The integration of medical resources is essentially the process of readjusting interests, and only when the interests of all parties are balanced, the effective integration of medical resources will be achieved. ACOs are now the most popular medical model for integrating medical resources in the United States. In the formation and operation of ACOs,the government has played a role of management and guidance on the basis of market allocation of resources. By the way of savings and risks sharing,the government encourages medical service providers to enhance collaboration and coordination,and strengthening patient protection by improving the medical service quality control, empowering patients' freedom of choice of health care suppliers, and launching anti-monopoly investigations for the purpose of putting a competitive pressure on ACOs. The development of ACOs might have certain reference signifi-cance for China to integrate medical resources. To establish an integrated medical care system in China,on the basis of the basic role of the market allocation of resources, the department of social medical insurance should effectively play the role of medical insurance purchaser,strengthening encouragement,guidance,and restraint of and supervision to medical institutions and medical staff.
