Integral National Economic Complex (under socialism), union of and interaction between all links of social production, distribution and exchange in the country. It is founded on socialist public ownership of the means of production and the advanced social division of labour. It is formed on the basis of state plans for economic and social development with the growth of productive forces, an advance in the branch and territorial division of labour, and the maturing of socialist relations of production. The establishment of the complex is finished when developed socialism has been built. The Soviet Constitution includes an article stressing that the country’s economy has turned into an integral economic complex. It embraces the economies of all constituent republics, the branches of material production, and the non-productive sphere. An integral part of the complex is science to the extent to which it acts as a directly productive force. With the advance of the international division of labour and the progress of socialist economic integration, the integral economic complex of the USSR becomes a component part of the world socialist economic system.
