Regional balance: The government is responsible for developing all regions and states in a balanced way and removing regional disparties. Development of backward regions so as to ensure a regional balance in the country is one of the major objectives of planned development. Therefore, the government had to locate new enterprises in backward areas and at the same time prevent the mushrooming growth of private sector unit in already advanced areas.
Economies of scale: Where large scale industries are required to be set up with huge capital outlay, the public sector had to step in to take advantage of economies of scale. The public sector acts as a check over the private sector. In the private sector there are very few industrial houses which would be willing to invest in heavy industries with the result that wealth gets concentrated in a few hands and monopolistic practices are encouraged.
