The Second Five Year Plan (1956-1961), based on the Mahalanobis model, is considered a landmark in Indian development planning for its strong emphasis on industrialisation, particularly heavy industries, its aim to significantly increase the rate of investment, and its explicit goal of establishing a socialistic pattern of society in India.
The plan shifted focus from agriculture (as in the first plan) to rapid industrialization with a focus on building a strong capital goods base through the development of heavy industries under the public sector. It aimed for a higher rate of growth and investment to achieve structural transformation of the economy.
The “socialistic pattern of society” resolution was adopted by the Indian National Congress at its Avadi session in 1955, influencing the objectives and approach of the Second Plan, which envisaged a dominant role for the public sector while allowing for a private sector within the overall planned framework.
