Major Industrial Regions of India

Geography › Industry · Topic 13.9

India's industrial regions are areas where industries cluster around ports, coalfields, big cities and markets. The usual classification gives eight major regions and a number of minor ones. The major regions are Mumbai-Pune, Hugli, Bengaluru-Tamil Nadu, Gujarat, Chotanagpur, Visakhapatnam-Guntur, the Delhi region and Kollam-Thiruvananthapuram.

Where Does It Fit?

This topic follows the world industrial regions and ends the macro on industry by giving the Indian pattern. It draws on the Indian steel, textile, chemical and engineering centres described earlier and leads to the transport network. Previous topic: Major Industrial Regions of the World. Next topic: Land Transport: Road Networks and Their Distribution.

Which Are the Eight Major Industrial Regions?

Region	Main centres	Industries and basis
Mumbai-Pune	Mumbai, Thane, Pune, Nashik, Solapur	Cotton textiles, chemicals, engineering, vehicles, petroleum, electronics; port, hydro-power, capital and market
Hugli	Kolkata, Howrah, Haldia, Hugli	Jute, engineering, chemicals, paper, petroleum; port, Raniganj coal, labour
Bengaluru-Tamil Nadu	Bengaluru, Coimbatore, Chennai, Madurai, Salem	Aircraft, machine tools, electronics, software, textiles, vehicles; hydro-power, skilled labour
Gujarat	Ahmedabad, Vadodara, Surat, Bharuch, Jamnagar	Cotton and synthetic textiles, chemicals, petroleum, fertilizers, ports and gas
Chotanagpur	Jamshedpur, Ranchi, Bokaro, Dhanbad, Durgapur, Rourkela	Iron and steel, heavy engineering; coal, ore, limestone
Visakhapatnam-Guntur	Visakhapatnam, Vijayawada, Guntur, Kakinada	Steel, shipbuilding, fertilizers, refining, sugar; port and coal of Godavari valley
Delhi region	Delhi, Gurugram, Faridabad, Meerut, Ghaziabad, Noida	Vehicles, electronics, engineering, textiles, services; market and capital
Kollam-Thiruvananthapuram	Thiruvananthapuram, Kochi, Alappuzha, Kollam	Agro-processing, rubber, fertilizers, shipbuilding, refining; hydro-power

Mumbai-Pune and Hugli grew first, around ports and under colonial trade. Chotanagpur is the base of heavy industry. Gujarat and Delhi regions have grown quickly in recent decades.

What Are the Minor Industrial Regions?

North India: Ambala-Amritsar (hosiery, sports goods, textiles), Saharanpur-Muzaffarnagar-Bijnor (sugar, paper), Jaipur-Ajmer (textiles, marble), Kanpur-Lucknow (leather, textiles, chemicals).
East and centre: Allahabad-Varanasi-Mirzapur (silk, carpets, glass), Bhojpur-Munger (rail, tobacco), Durg-Raipur (steel, cement), Bilaspur-Korba (aluminium, power), Indore-Ujjain (textiles).
South and west: Kolhapur-South Maharashtra (sugar, textiles), Adilabad-Nizamabad (cotton, paper), Northern and Middle Malabar (coir, tiles, textiles).
North-east: the Brahmaputra valley (oil refining, tea, plywood).

Locational advantages for these regions are local raw material, a market and the presence of an entrepreneur class.

How Do Policy and Corridors Shape the Map?

Industrial policies: the Industrial Policy Resolution of 1956 gave the public sector a major role and set up plants in backward areas such as Bhilai and Rourkela. The reforms of 1991 opened the economy to private and foreign investment.
Special Economic Zones: the Special Economic Zones Act, 2005 created duty-free enclaves for export, with large zones in Gujarat, Maharashtra, Tamil Nadu, Andhra Pradesh and Karnataka.
Corridors: the Delhi-Mumbai Industrial Corridor, Chennai-Bengaluru, Amritsar-Kolkata, Visakhapatnam-Chennai and other corridors form the National Industrial Corridor Development Programme, with industrial nodes along freight rail and road links. Check the latest status of nodes.
Make in India: started in 2014 to raise manufacturing; the Production Linked Incentive schemes of 2020 and after target sectors such as electronics, pharmaceuticals and automobiles.
Balance: industry remains concentrated in a few coastal and metro regions, and states such as Bihar, Odisha and the north-east lag. Reducing regional imbalance needs infrastructure, power and skills.

The map keeps changing, so use the latest policy data when writing an answer.

What Explains the Rise of Newer Regions?

Gujarat: ports at Kandla, Mundra and Hazira, gas and refinery supply at Jamnagar, a long business tradition and an active state policy have made it a leader in chemicals, petroleum, textiles and engineering.
Bengaluru-Tamil Nadu: hydro-power from Mettur and Pykara, public sector aerospace and machine tool units, universities and later software firms made the region a hub of knowledge industry. Chennai-Hosur-Oragadam is a major automobile belt.
Delhi region: the national market, capital, skilled workers and road and rail links drew vehicle, electronics and service firms to Gurugram, Noida and Faridabad.
Coastal advantage: most large regions have a port, which lowers the cost of imports of oil, coal and machinery and of exports of finished goods.

Points to Remember

Chotanagpur is the heavy industry region.
Hugli grew on jute and the port.
Mumbai-Pune is the largest region.
The SEZ Act is of 2005.
Make in India began in 2014.

Do Not Confuse With

Hugli and Chotanagpur Port and jute region versus coal and steel region
Major and minor regions Eight with large clusters versus smaller local ones
SEZ and industrial corridor Export enclave versus a belt along transport links

Memory Hook

Eight majors from Mumbai to Hugli: coast, coal and capital have drawn the factory map.

Mains Angle

Questions ask for the distribution of industrial regions and the reasons for regional imbalance. These points add depth.

Factors Ports, coal, market, policy
Imbalance Coastal and metro concentration
Corridors Spread of industry

Frequently Asked Questions

How many major industrial regions are there in India?

India is commonly divided into eight major industrial regions: Mumbai-Pune, Hugli, Bengaluru-Tamil Nadu, Gujarat, Chotanagpur, Visakhapatnam-Guntur, the Delhi region and Kollam-Thiruvananthapuram. Besides these there are several minor regions such as Ambala-Amritsar, Indore-Ujjain, Jaipur-Ajmer and the Brahmaputra valley, each with industries linked to local resources.

Why is Chotanagpur a major region for heavy industry?

The Chotanagpur plateau region has coal in the Damodar valley, iron ore in Jharkhand, Odisha and Chhattisgarh, limestone, manganese and water, which suit iron and steel and heavy engineering. Steel plants at Jamshedpur, Bokaro, Durgapur and Rourkela and engineering units at Ranchi make it the heart of Indian heavy industry.

Which was the oldest industrial region of India?

The Hugli industrial region around Kolkata and the Mumbai-Pune region are the oldest. Hugli grew on the jute industry, the port, coal from Raniganj and cheap labour, while Mumbai-Pune grew on cotton textiles, the port, capital from trade and hydro-power from the Western Ghats during the colonial period.

What is the Special Economic Zones Act, 2005?

The Special Economic Zones Act, 2005 provided for duty-free enclaves treated as foreign territory for trade, with tax benefits and simpler rules, to promote exports and investment. Large zones were set up in Gujarat, Maharashtra, Tamil Nadu, Andhra Pradesh and Karnataka, mainly in information technology, engineering and petroleum products.

What is an industrial corridor?

An industrial corridor is a planned belt of industrial nodes, cities and infrastructure along a major transport route such as a freight rail line or highway. India's National Industrial Corridor Development Programme includes the Delhi-Mumbai Industrial Corridor and Chennai-Bengaluru corridor, which aim to spread manufacturing to new areas. Check the latest status of nodes.
