Five-year plans of the Soviet Union

The five-year plans for the development of the national economy of the Union of Soviet Socialist Republics (USSR) (Russian: пятилетние планы развития народного хозяйства СССР, pyatiletniye plany razvitiya narodnogo khozyaystva SSSR) consisted of a series of nationwide centralized economic plans in the Soviet Union, beginning in the late 1920s. The Soviet state planning committee Gosplan developed these plans based on the theory of the productive forces that formed part of the ideology of the Communist Party for development of the Soviet economy.
