What is public administration and what is private administration?

China's traditional administrative law theory holds that administration can be divided into public administration and private administration. Public administration refers to the management of state and public affairs, which is related to the use of public power; Private administration refers to the administration of social organizations and enterprises, which is related to the use of private power. The administration studied by administrative law can be divided into state administration and non-state administration, as well as public administration and private administration. Among them, non-state administration mainly refers to private administration, that is, the implementation and management activities of private enterprises, organizations and groups. Besides state administration, public administration also includes the administration of non-state public organizations, such as public associations (lawyers' associations, etc.). ) and public enterprises and institutions (state-owned enterprises, public schools, etc. ).
