The Second Five Year Plan (1956-1961) was heavily influenced by the Mahalanobis model, which advocated for rapid industrialization with a focus on the development of heavy and basic industries. The rationale was that building a strong base of capital goods industries (like steel, machinery, power generation) would provide the necessary inputs for the future growth of other sectors, including consumer goods and agriculture. While small scale industries were also encouraged, the primary emphasis and investment were directed towards large-scale heavy and capital goods industries.
