State ownership (also called public ownership and government ownership) refers to property interests that are vested in the state or a public body representing a community as opposed to an individual or private party. State ownership may refer to ownership and control of any asset, industry, or enterprise at any level (national, regional, local or municipal); or to non-governmental public ownership. The process of bringing an asset into state ownership is called nationalization or municipalization. State ownership is one of the three major forms of property ownership, differentiated from private, cooperative and common ownership.
