There is a high degree of information asymmetry in medical services.Public hospitals are characteristic of the nature of multi-layer principal-agent relationships.Asymmetric information can lead to inconsistent value goals between the principal and the agent,giving birth to the government regulation capture as a result.Such capture ranks a fundamental cause for diluted public welfare nature of public hospitals.To offset such capture at public hospitals calls for reconstruction of government regulation system within the framework of public hospital corporate governance at an institution level.It is also necessary to eliminate the information asymmetry and its negative results,bringing public hospitals back on track to public welfare.

Guangdong province is experimenting with a model composed of various types of medical alliances, having achieved initial success with some of them and preliminarily has formed a holistic governance pattern. Experiences behind such initial success lied in a coordinated top-level design, reasonable and classified guidance, leader role of key governance subjects, and the construction of a telemedical system. However, as analyzed from the angle of collaborative governance, existing medical alliances have not yet formed a community of services, that of responsibility, that of interests, and that of services. In this consideration, the authors recommended to strengthen the collaborative governance of such alliances by respective governance subjects based on the theories of integrated medical service system and collaborative governance, eventually forming an integrated medical and health service system.
