1. The Mahalanobis Model and the Second Five-Year Plan (basic)
Welcome to the beginning of our journey into the Public Sector Enterprises (PSEs) of India. To understand why the Indian government owns massive steel plants or power projects, we must go back to 1956—the year India decided to take a "Big Push" toward industrialization through the Second Five-Year Plan (1956–1961).
The architect of this plan was the renowned statistician Prasanta Chandra Mahalanobis. His strategy, often called the Nehru-Mahalanobis Model, shifted the nation's focus from agriculture (the priority of the First Plan) to rapid industrialization. The core philosophy was simple but bold: to become truly independent, India needed to build the machines that build other machines. This meant investing heavily in Capital Goods (like iron, steel, and heavy chemicals) rather than just consumer goods like clothes or food Indian Economy, Nitin Singhania, p.135.
Because these heavy industries required massive amounts of money and had long gestation periods (meaning they take a long time to become profitable), the private sector was unwilling or unable to lead the way. Therefore, the Mahalanobis model placed the Public Sector at the "commanding heights" of the economy. The state became the primary entrepreneur, leading to the birth of iconic projects like the Bhilai, Durgapur, and Rourkela steel plants Indian Economy, Vivek Singh, p.207.
This strategy was heavily inspired by the Soviet (USSR) model of planning, emphasizing import substitution—the idea that India should produce its own industrial requirements rather than relying on expensive imports from the West Politics in India since Independence, NCERT, p.50. While this created a strong industrial base, it also meant the government had to take on significant foreign loans to fund these ambitious projects Indian Economy, Nitin Singhania, p.138.

Remember: The 2nd Plan was the "Industrial Plan." Think of Mahalanobis as the man who wanted to build the "bones" (Heavy Industry) of the Indian economy so the "flesh" (Consumer Goods) could grow later.
Key Takeaway The Mahalanobis Model established the Public Sector as the primary driver of the Indian economy by prioritizing heavy capital goods industries to achieve long-term self-reliance.

2. Industrial Policy Resolution (IPR) 1956 (intermediate)
To understand the backbone of India’s industrial journey, we must look at the
Industrial Policy Resolution (IPR) of 1956. Often hailed as the
'Economic Constitution of India' or the
'Bible of State Capitalism', this policy was formulated to align with the
socialistic pattern of society adopted by the government during the mid-1950s
Indian Economy, Nitin Singhania, p.403. It provided the legal and structural framework for the
Second Five-Year Plan, which was heavily influenced by the
P.C. Mahalanobis model — a strategy that prioritized the development of heavy and basic industries to make India self-reliant.
The most defining feature of IPR 1956 was its threefold classification of industries, replacing the older fourfold system of 1948 History, Class XII (Tamilnadu State Board), p.122. This classification clearly demarcated the roles of the public and private sectors:
| Category |
Scope & Control |
Key Examples |
| Schedule A |
Absolute monopoly of the State. Private players were excluded. |
17 industries including Arms, Atomic Energy, Railways, and Iron & Steel. |
| Schedule B |
Mixed sector where the State would take the lead in starting new units, but the private sector was encouraged to supplement these efforts. |
12 industries including Fertilizers, Machine tools, and Synthetic rubber. |
| Schedule C |
Open to the private sector, though still subject to government regulations and licensing. |
All remaining industries not mentioned in Schedules A or B. |
Beyond just classification, IPR 1956 introduced the
Industrial Licensing Policy. To set up a new unit or expand an existing one, private entrepreneurs needed a government license. This wasn't just about control; it was a tool for
regional equality. Licenses were granted more easily for backward regions to ensure that industrial growth wasn't concentrated in just a few cities. Furthermore, the policy recognized that industrialization required more than just factories — it required brains. Hence, it stressed the development of
technical and managerial skills, leading to the birth of ITIs and business management courses in universities
Indian Economy, Nitin Singhania, p.378.
Key Takeaway IPR 1956 established the State as the "commanding heights" of the economy, using a three-tiered classification (Schedules A, B, and C) to drive heavy industrialization and regional balance.
Remember The 1956 policy moved from a 4-fold (1948) to a 3-fold classification. Think of it as: A (All Gov), B (Both), C (Consumer/Private).

3. Evolution of Public Sector Undertakings (PSUs) (basic)
At the dawn of independence, India faced a massive challenge: how to transform a stagnant colonial economy into a modern industrial powerhouse. The private sector at the time lacked the capital and risk appetite for massive long-term projects. Consequently, the government adopted a
plan-oriented development strategy in the 1950s, placing the public sector at the "commanding heights" of the economy. In 1951, India started with a humble
five Central Public Sector Enterprises (CPSEs), but this number grew exponentially as the state expanded into trade, energy, and transport
Indian Economy, Nitin Singhania, Chapter 12, p.384. This growth was not just about size; it was about building the backbone of the nation's infrastructure
Geography of India, Majid Husain, Chapter 11, p.87.
The Second Five-Year Plan (1956–61) was the turning point for heavy industry. During this era, India actively sought international technical cooperation to build its industrial giants. For instance, the Bhilai Steel Plant (1959) in Chhattisgarh was established with the critical assistance of the Soviet Union (USSR), becoming a symbol of Indo-Soviet economic friendship. Similarly, the Bokaro Steel Plant (1964) was also a Soviet-aided project Geography of India, Majid Husain, Chapter 11, p.33-34. These collaborations weren't limited to the USSR; the Durgapur Steel Plant in West Bengal was built with British (UK) assistance, showcasing India's pragmatic approach to global technology transfers.
As we moved into the later decades, the public sector's role shifted from purely industrial production to becoming growth leaders in services and commerce. However, this rapid expansion came with growing pains. By the late 20th century, many PSUs faced criticism for low productivity, external interference, and accumulating annual losses Geography of India, Majid Husain, Chapter 11, p.89. While as of March 2021, there are approximately 366 CPSEs, the modern focus has shifted from mere expansion to improving efficiency and professional management to ensure these units remain viable profit centers Indian Economy, Nitin Singhania, Chapter 12, p.384.
1951 — India starts with only 5 Central Public Sector Enterprises (CPSEs).
1959 — Bhilai Steel Plant established with Soviet (USSR) cooperation.
1964 — Bokaro Steel Plant commissioned, also with Soviet assistance.
2021 — The number of CPSEs reaches 366, reflecting massive sectoral expansion.
Key Takeaway The evolution of PSUs in India was driven by the need for state-led industrialization, moving from just 5 units in 1951 to over 300 today, heavily supported by international technical collaborations in the early years.

4. Indo-Soviet Economic and Technical Cooperation (intermediate)
To understand India's industrial backbone, we must look at the 'special relationship' between India and the Soviet Union (USSR). Post-independence, India adopted a
state-led development model, particularly during the Second Five-Year Plan (1956–61). At a time when Western nations were often hesitant to provide technology and capital for heavy industries in a non-aligned nation, the Soviet Union stepped in with extensive economic and technical assistance
NCERT Class XII: Contemporary World Politics, Chapter 1: The End of Bipolarity, p.12. This cooperation wasn't just about money; it involved the transfer of complex technical know-how and the training of thousands of Indian engineers, which was vital for the growth of our
Public Sector Enterprises (PSEs).
The crown jewels of this collaboration were the massive iron and steel plants. The Bhilai Steel Plant, established in 1959 in Chhattisgarh, became a symbol of Indo-Soviet friendship and a primary engine for India's industrial growth during the Second Plan Majid Husain: Geography of India, Chapter 11: Industries, p.33. This was followed by the Bokaro Steel Plant, commissioned in 1964. It is a common misconception that Bokaro was built with British help; in reality, it was a significant Soviet-aided project designed to make India self-reliant in steel production Majid Husain: Geography of India, Chapter 11: Industries, p.34. Beyond steel, the USSR assisted in setting up Bharat Heavy Electricals Ltd. (BHEL) and several machine tool industries, forming the 'commanding heights' of the Indian economy.
One of the most unique features of this cooperation was the Rupee-Rouble trade mechanism. During phases when India faced severe shortages of foreign exchange (like US Dollars), the Soviet Union accepted Indian currency for trade payments NCERT Class XII: Contemporary World Politics, Chapter 1: The End of Bipolarity, p.12. This allowed India to import heavy machinery and oil without draining its precious forex reserves, effectively insulating the early PSEs from global currency fluctuations.

5. Classification of PSUs: Maharatna, Navratna, and Miniratna (exam-level)
In the landscape of Indian industry, Central Public Sector Enterprises (CPSEs) are those companies where the direct holding of the Central Government (or other CPSEs) is 51% or more. To shed the rigid bureaucratic control of the past and foster a competitive spirit, the government introduced a grading system that grants varying degrees of financial and operational autonomy to these firms. This classification is managed by the Department of Public Enterprises and is divided into three prestigious tiers: Maharatna, Navratna, and Miniratna Indian Economy, Nitin Singhania (ed 2nd 2021-22), Indian Industry, p.381.
The Maharatna status is the highest category, reserved for the "giants" of the Indian economy. To qualify, a company must already hold Navratna status, be listed on an Indian stock exchange, and possess a significant global presence. More importantly, it must meet rigorous financial benchmarks over the last 3 years: an average annual net profit after tax of over ₹5,000 crore, an average annual net worth of over ₹15,000 crore, and an average annual turnover of more than ₹25,000 crore Indian Economy, Nitin Singhania (ed 2nd 2021-22), Indian Industry, p.383. Once a CPSE becomes a Maharatna, it gains the power to invest up to ₹5,000 crore in a single project without seeking prior government approval, allowing for much faster decision-making in volatile global markets.
Below the Maharatnas are the Navratnas and Miniratnas (Category I and II). While Maharatnas are the global face of India's PSU sector, Navratnas like Bharat Electronics Ltd (BEL) or Hindustan Aeronautics Ltd (HAL) are the backbone of domestic industrial capability Indian Economy, Nitin Singhania (ed 2nd 2021-22), Indian Industry, p.382. The classification is summarized in the table below:
| Status |
Key Requirement Highlights |
Investment Autonomy Limit |
| Maharatna |
Navratna status + ₹5,000Cr avg. net profit + Global presence |
Up to ₹5,000 crore |
| Navratna |
Miniratna Category-I + Score of 60/100 on performance parameters |
Up to ₹1,000 crore or 15% of net worth |
| Miniratna (Cat-I) |
Profit in last 3 years + positive net worth |
Up to ₹500 crore or net worth (whichever is less) |
Key Takeaway The PSU classification system (Maharatna, Navratna, Miniratna) is a tool for decentralization, granting successful companies the financial freedom to make large-scale investments and compete globally without constant bureaucratic oversight.

6. Key Integrated Steel Plants and Foreign Collaborations (exam-level)
To understand India's industrial backbone, we must look at the **Second Five-Year Plan (1956–1961)**. Under the Mahalanobis model, India shifted its focus toward heavy industries, particularly steel, to achieve self-reliance. Since India lacked the massive capital and specialized technology required at the time, the government entered into strategic partnerships with global powers. This era saw the birth of the 'Big Three' integrated steel plants: **Bhilai**, **Rourkela**, and **Durgapur**, each backed by a different foreign nation.
Geography of India, Majid Husain, p.28
The Bhilai Steel Plant in Chhattisgarh was established in 1959 with the assistance of the Soviet Union (USSR). It was a flagship project of Indo-Soviet friendship, designed to produce rails and heavy steel plates. In contrast, the Rourkela Steel Plant in Odisha was set up in collaboration with West German firms, specifically Krupps and Demag. Rourkela was unique because it was the first in India to use the LD (Linz-Donawitz) process of steelmaking and focused on flat products like hot-rolled sheets and tin plates. Geography of India, Majid Husain, p.34
The third major plant of that era was the Durgapur Steel Plant in West Bengal, built with the help of a British consortium. Later, in 1964, the Bokaro Steel Plant was established in Jharkhand. While it came after the Second Plan, it is often grouped with the others due to its scale; notably, like Bhilai, Bokaro was also built with Soviet assistance after the United States declined to fund a public-sector project at the time. Geography of India, Majid Husain, p.28

7. Solving the Original PYQ (exam-level)
Now that you have mastered the industrial landscape of post-independence India, you can see how the Second Five-Year Plan's emphasis on heavy industry required strategic international partnerships. As detailed in Geography of India, Majid Husain, the establishment of these massive industrial hubs relied on technical cooperation to bridge India's technology gap. This question tests your ability to accurately pair these infrastructure projects with their respective global partners—specifically distinguishing between the roles played by the USSR and the United Kingdom during the Cold War era.
Let’s walk through the reasoning: Statement 1 correctly identifies the Bhilai Steel Plant as a flagship project of Indo-Soviet relations, established in 1959 with extensive technical and economic assistance from the USSR. However, Statement 2 contains a classic "distractor". While the British did assist in India's industrialization, their primary contribution was the Durgapur Steel Plant in West Bengal. The Bokaro Steel Plant, much like Bhilai, was actually built with Soviet collaboration, as confirmed by Contemporary World Politics, NCERT Class XII. Since only the first statement holds true, the correct answer is (A) 1 only.
UPSC frequently uses "association swaps" as a trap, especially when names start with the same letter or belong to the same industrial sector. A common mistake is to associate "British" with "Bokaro" due to the phonetic similarity, whereas the correct geographical and historical link connects Bhilai and Bokaro both to the Soviet Union. Options (B) and (C) are designed to catch students who remember that the British helped a steel plant but fail to distinguish it from the Soviet-aided projects. To avoid this trap, always categorize these plants as a set: Rourkela (Germany), Durgapur (UK), and Bhilai/Bokaro (USSR).
