Encyclopædia Britannica:
public enterprise
a business organization wholly or partly owned by the state and controlled through a public authority. Some public enterprises are placed under public ownership because, for social reasons, it is thought the service or product should be provided by a state monopoly. Utilities (gas, electricity, etc.), broadcasting, telecommunications, and certain forms of transport are examples of this kind of public enterprise.

An obscure entry indeed. 'Der Staat als Unternehmer' is a political polemic. 'Public enterprise', in contrast, is a technical term. I cannot find any context in which one translates to the other.
