Mixed economy.

Explanation:

Mixed economy is a system in which the planned production processes operate simultaneously, when the state acts as an actor - acting directly in production - but also the model of market production, when there is production carried out by private initiative. In a mixed economic system, state action occurs through state-owned enterprises. In addition, the State also acts as a regulator of private activity, in order to maintain a healthy environment for economic transactions.
