Evolution of concepts of structuring national economy

The article studies theoretical views of representatives of main economic schools: mercantilism, physiocrats, classical, Marxist, Keynesian and institutional. It underlines that non-intervention of the state into regulation of economic processes, supporters of which were classical and neo-classical economic schools, results in deformation of the structure at the national level. The article shows that representatives of Marxist, Keynesian and neo-classical schools considered mostly the reproduction structure while analysing the economic structure. It studies the structure of the national economy from the point of view of evolutional approach. It marks out criteria of classification of structural transformations: by the level of functioning of economy and level of development of economy.
