The idea of the Five Year Plan was adopted in India from which of the following country?

Union of Soviet Socialist Republics

The idea of Five Year Plan was adopted in India from Union of Soviet Socialist Republics.

The concept of Five-Year Plans in India was inspired by the Soviet Union's (USSR) central planning system.
Nehru was impressed with the Soviet Union's approach and believed that a similar model could be adapted to India's needs to achieve rapid economic development and reduce poverty.
The idea of the FYP is very simple: the Government of India prepares a document that has a plan for all its income and expenditure for the next five years.
Accordingly, the budget of the central and all the State governments is divided into two parts: ‘Plan-budget’ and ‘Non-Plan’ budget .
A five-year plan has the advantage of permitting the government to focus on the larger picture and make a long-term intervention in the economy.
