Question of 19

Q.Read the following text carefully : With independence, India chose the closed economy model in pursuit of its objective of industrial self-sufficiency. As a result, industrial structure has become considerably important. In the post-independence era, the industrial growth was rapid during the first two decades, especially during the Second and Third Plan period. The Second Plan introduced 'Industrial Revolution' in the country. The main reasons for high rates of industrial growth witnessed during this period were due to :

(i) Emphasis on industrialisation in economic policies.
(ii) Making industrial growth the main objective in the industrial policy and planning.
(iii) Huge investments being made to support capacity creation in the industrial sector.
(iv) Growing demands for a variety of new products on the part of the urban consumers and the relatively better-off sections of the society.
(v) Pace of economic expansion supported by domestic savings and inflow of resources from abroad. On the basis of the given text and common understanding, answer the following questions :
(a) State the time period of the Second Five Year Plan of India.
(b) Who is considered as the Father of the Second Five Year Plan of India ?
(c) Discuss briefly any two reasons behind the industrial growth during the Second and Third Five Year Plans of India.

The Second Five Year Plan (1956–61), designed by P.C. Mahalanobis, triggered India's Industrial Revolution through heavy state investment in capital goods and a closed-economy strategy that prioritized industrialization over all else.


India's post-independence industrial policy rested on a simple conviction: self-reliance required a strong domestic industrial base, insulated from foreign competition. The Second and Third Plans translated that conviction into action, and the results were dramatic. Industrial growth rates during 1956–66 were among the highest India had seen, driven by deliberate policy choices and structural shifts in the economy.

(a) Time Period of the Second Five Year Plan

The Second Five Year Plan ran from 1956 to 1961. It marked a decisive break from the First Plan's agricultural focus and laid the foundation for India's heavy-industry-led growth model.

(b) Father of the Second Five Year Plan

Professor Prasanta Chandra Mahalanobis is considered the architect of the Second Five Year Plan. A statistician and economist, Mahalanobis designed the plan around a two-sector growth model that prioritized capital goods (machinery, steel, heavy equipment) over consumer goods, arguing that long-term industrialization required building the capacity to produce machines that produce machines. His influence was so profound that the Second Plan is often called the "Mahalanobis Plan."

(c) Two Reasons Behind Industrial Growth During the Second and Third Plans

1. Policy Emphasis on Industrialization and Massive Public Investment

The Second Plan made industrial growth the central objective of economic policy, not a side benefit. The government channeled huge investments into building capacity in core industries—steel plants, heavy machinery, chemicals, power generation. Public sector undertakings (PSUs) were established to anchor these capital-intensive sectors, which private capital was either unwilling or unable to finance at the required scale.

This was not incremental expansion; it was a structural transformation. The Industrial Policy Resolution of 1956 reserved seventeen industries for the public sector, ensuring that the state controlled the "commanding heights" of the economy. The result was a rapid buildup of industrial infrastructure that would have taken decades under a laissez-faire approach.

2. Rising Domestic Demand from Urban Consumers and Better-Off Sections

Industrialization does not happen in a vacuum—it needs buyers. The Second and Third Plans coincided with growing demand for manufactured goods from India's urban middle class and relatively affluent rural households. As incomes rose (partly due to public-sector employment and partly due to agricultural surpluses in some regions), demand for consumer durables, textiles, processed foods, and other industrial products expanded. …
