The first important feature of a mixed economy is the co-existence of both private and public enterprise. In fact, in a mixed economy, 

There are three sectors of industries:
(i) Private Sector : Production and distribution is managed and controlled by private individuals and groups. Industries in this sector are based on self-interest and profit- motive. The system of private property exists and personal initiative is given full scope.

(ii) Public Sector : Industries in this sector are not primarily profit-oriented but are set up by the state for the welfare of the community.

(iii) Joint Sector : A sector in which both the government and the private enterprises have equal access, and join hands to produce a commodity, leading to the establishment of joint sector.

Secondly, a mixed economy is a planned economy, i.e., an economy in which the government has a clear and definite economic plan.

Thirdly, in a mixed economy, balanced regional development is expected.

Fourthly, in a mixed economy, a dual system of pricing exists.
