Industrial location factors and classification of industries

Detail

1. The basic rule of industrial location

• Industrial location means the place a factory chooses to set up.
• Basic rule: an industry sets up where its production cost is lowest. Production cost includes raw material, labour, power, transport and getting goods to buyers.
• The factors work together. One strong factor rarely decides the location alone. A site wins when several factors meet in one place.
• Early Indian examples:
• First modern cotton mill, Mumbai (1854). Mumbai had a market, a port for importing machines and exporting cloth, money from traders, workers, and a humid climate in which cotton thread breaks less.
• TISCO, Jamshedpur, Jharkhand (1907). It was built close to iron ore and coal in the Chota Nagpur plateau, had water from the Subarnarekha and Kharkai rivers, and was near the port of Kolkata.

2. Location factors one by one

(a) Market: the most important factor

• Market means people who want the goods and have the money to pay for them (demand plus purchasing power).
• A crowd of poor people is not a large market, because they cannot pay.
• Some goods are best made near buyers: goods that break easily, spoil quickly or become bulky after they are made, such as bottled drinks, furniture and refined petroleum products.

(b) Raw material

• A raw material pulls the industry close to its source when it is:
• Cheap and bulky. Moving it far costs more than the material itself.
• Weight-losing. The finished product weighs much less than the inputs. For example, iron ore, coal and limestone become a smaller weight of steel.

• Perishable. It spoils quickly. Sugarcane loses sucrose within about a day of cutting, and milk goes sour.

• Examples:

Industry	Why it stays near its raw material	Indian example
Iron and steel	Ore and coal are heavy and lose weight	Chota Nagpur belt (Jamshedpur, Bokaro, Rourkela)
Sugar	Cane is perishable	Uttar Pradesh, Maharashtra cane belts
Cement	Limestone is bulky	Limestone areas of Madhya Pradesh, Rajasthan, Andhra Pradesh
Dairy / agro-processing	Milk and fruit spoil quickly	Anand (Gujarat)

(c) Labour

• Some industries still need skilled or cheap workers, for example handloom weaving and diamond cutting.
• Labour matters less today because automation (machines and computers doing work that people once did) has cut the number of workers needed.

(d) Energy (power)

• Power-hungry industries use huge amounts of electricity, so they go to where power is cheap.
• Aluminium smelting is the classic case. It needs a lot of electricity to separate aluminium from bauxite. An Indian example is Renukoot (Uttar Pradesh), near the Rihand hydel project.
• Coal has lost some pull. In the past, steel and other heavy industries sat on coalfields. Now power can be sent long distances, and hydel power (electricity from falling water) and petroleum offer other choices.

(e) Transport and communication

• Cheap, fast transport brings in raw materials and takes finished goods to market.
• Ports, railway junctions and highway nodes attract factories. Mumbai, Kolkata and Chennai grew as industrial centres partly because they are ports.
• Good communication (telephone, internet) matters most for high-tech and service-linked industries.

(f) Government regional policy

• Regional policy means the government's plan to spread industry so that backward areas also develop (balanced regional development).
• Tools: tax breaks, cheap land, public-sector plants placed in backward regions, and industrial estates.
• Industrial corridors today:
• The National Industrial Corridor Development Programme (NICDP) builds greenfield (new, on empty land) industrial smart cities "ahead of demand". It uses a 'plug-n-play' idea, where developed land with ready utilities lets a firm start work at once, and a 'walk-to-work' design [2].
• Eleven corridors are mapped [2]:
  • Delhi–Mumbai (DMIC)
  • Amritsar–Kolkata (AKIC)
  • Chennai–Bengaluru (CBIC)
  • Vizag–Chennai (VCIC)
  • Bengaluru–Mumbai (BMIC)
  • Odisha Economic Corridor
  • Hyderabad–Nagpur
  • Hyderabad–Warangal
  • Hyderabad–Bengaluru
  • Extension of CBIC to Kochi via Coimbatore
  • Delhi–Nagpur
• Cabinet decision of 28 August 2024: 12 new industrial nodes/cities, with an estimated investment of ₹28,602 crore, in 10 states along 6 corridors [2]. They are:
  • Khurpia (Uttarakhand)
  • Rajpura–Patiala (Punjab)
  • Dighi (Maharashtra)
  • Palakkad (Kerala)
  • Agra and Prayagraj (Uttar Pradesh)
  • Gaya (Bihar)
  • Zaheerabad (Telangana)
  • Orvakal and Kopparthy (Andhra Pradesh)
  • Jodhpur–Pali (Rajasthan)
• Expected jobs: about 1 million direct and up to 3 million indirect [2].
• Finished nodes on DMIC (2024) [2]:
  • Dholera SIR, Gujarat. About 100 km south-west of Ahmedabad. Described as India's first platinum-rated industrial smart city. Its SPV was set up in 2016, owned 51% by Gujarat and 49% by the NICDC Trust.
  • AURIC, Maharashtra. At Shendra–Bidkin near Aurangabad, about 10,000 acres. 60% of the land is for industry.
  • Integrated Industrial Township, Greater Noida (Uttar Pradesh).
  • Vikram Udyogpuri, Madhya Pradesh. Near Ujjain, 442.3 ha.

(g) Agglomeration economies

• Agglomeration economies are the savings a firm gets by being close to a leader industry and to many other units.
• Cause → process → result:
• A big "leader" plant comes up, such as a steel plant or a car factory.
• Suppliers, repair shops, banks, trained workers and transport services gather around it.

• Each new firm saves money on inputs, skills and services, so even more firms come. This produces a cluster.

• Indian examples: car-parts clusters around Gurugram–Manesar (Haryana) and Chennai (Tamil Nadu), and the textile cluster at Tiruppur (Tamil Nadu).

3. Footloose industries

• Footloose industries can be located almost anywhere, because no single raw material or power source ties them down.
• Features:
• They use components (ready-made parts) that are available everywhere.
• They make goods that are light but of high value.
• They employ few workers.
• They are generally non-polluting.

• Their main need is good road access.

• Examples: electronics assembly, computer parts, diamond and watch making.

4. High-tech industries and technopolis

• High-tech industry is the newest kind of manufacturing. It depends heavily on R and D (research and development: scientific work to create new products).
• Features:
• Most workers are white-collar (office, professional and technical staff), not machine operators.
• Firms sit in neat, low, scattered buildings in campus-like technology parks.

• Sectors: robotics, computer-aided design, electronics, biotechnology, pharmaceuticals.

• Technopolis: a region where high-tech firms cluster so densely that the region keeps growing on its own (it is self-sustaining). The best-known example is Silicon Valley near San Francisco, USA. Seattle is another.

• Is Bengaluru a technopolis? Points to weigh:
• For: a dense IT and electronics cluster; research bodies such as IISc and ISRO; aerospace firms (HAL); many start-ups and venture capital firms; skilled migrant workers.
• Against: much of its work is IT services, not high-tech manufacturing; it has serious infrastructure strain (traffic and water); it does not yet generate home-grown core technology on Silicon Valley's scale.

5. Classification of industries

Basis	Classes	Examples / key point
Raw material	Agro-based, mineral-based, chemical-based, forest-based, animal-based	Cotton textiles, sugar (agro); iron and steel, cement (mineral); fertiliser, petrochemicals (chemical); paper, furniture (forest); leather, wool (animal)
Role (main function)	Basic or key industries and consumer industries	Basic industries make goods that other industries use, such as iron and steel, copper and aluminium smelting. Consumer industries make goods people use directly, such as soap, tea and TVs
Capital (investment)	Small-scale vs large-scale	Small-scale is defined by a money ceiling (see the table below)
Size	Household or cottage, small-scale, large-scale	A cottage industry is run at home by family members with simple tools, such as handicrafts and pottery
Ownership	Public, private, joint, cooperative	Public: BHEL, SAIL. Private: TISCO, Bajaj Auto, Dabur. Joint: Oil India Ltd. Cooperative: Maharashtra sugar, Kerala coir
Bulk and weight	Heavy vs light	Heavy industries use bulky inputs and make bulky goods (iron and steel). Light industries use light inputs and make light goods (electrical goods)

Ownership types defined:

• Public sector: owned and run by the government.
• Private sector: owned and run by individuals or groups of individuals.
• Joint sector: run jointly by the state and private individuals or firms.
• Cooperative sector: see section 6 below.

Small-scale limit: how the definition changed

Period	Basis	Micro	Small	Medium
NCERT	Investment only	—	Ceiling of ₹1 crore	—
MSMED Act 2006 (manufacturing)	Investment in plant and machinery	up to ₹25 lakh	₹25 lakh – ₹5 crore	₹5 – ₹10 crore [5]
From 1 July 2020	Composite: investment and annual turnover	₹1 cr / ₹5 cr	₹10 cr / ₹50 cr	₹50 cr / ₹250 cr [4]
From 1 April 2025	Composite (investment / turnover)	₹2.5 cr / ₹10 cr	₹25 cr / ₹100 cr	₹125 cr / ₹500 cr [3]

• Composite criteria: a unit must stay within both limits, investment and turnover, to fit a class. The 2020 change also stopped treating manufacturing and service units differently [4].
• The 2025 increase: announced in the Union Budget 2025-26, it raised investment limits 2.5 times and turnover limits 2 times. The aim was to help firms grow larger, adopt new technology and raise capital without losing MSME benefits [3].

6. Cooperative sector industry

• Definition: an industry that is owned and run by the people who produce or supply the raw material, by workers, or by both.
• How it works:
• Members pool their resources (money, raw material, labour).

• Profits or losses are shared in proportion to each member's contribution.

• Why it suits seasonal, farmer-supplied industries:

• Many small farmers supply cane or milk daily or seasonally.
• A jointly owned mill or dairy assures them of a buyer and a fair price, and middlemen are removed.

• The factory gets a steady, nearby supply of perishable raw material.

• Examples:

• Sugar mills of Maharashtra. The cooperative sugar belt is spread across western Maharashtra.
• Coir industry of Kerala. Coir is fibre from coconut husk.
• Amul, Anand (Gujarat). A cooperative dairy whose model drove India's White Revolution (Operation Flood).

Prelims Hooks

• Most important location factor: market, which means demand plus purchasing power, not population alone.
• Weight-losing raw material (steel) and perishable raw material (sugar, dairy) both make an industry raw-material-oriented.
• Aluminium smelting goes to cheap power, not to bauxite mines.
• Footloose industries use components available everywhere, employ few people, pollute little and need road access. Trap: they are not tied to raw material.
• Ownership pairs: BHEL, SAIL = public; TISCO, Bajaj Auto, Dabur = private; Oil India Ltd = joint; Amul, Maharashtra sugar mills, Kerala coir = cooperative.
• Basic or key industries supply other industries. Iron and steel and copper and aluminium smelting are key industries, not consumer industries.
• MSME limits from 1 April 2025: micro ₹2.5 crore investment / ₹10 crore turnover; small ₹25 cr / ₹100 cr; medium ₹125 cr / ₹500 cr [3]. The composite investment-plus-turnover test began on 1 July 2020 [4].
• NICDP, 28 August 2024: 12 industrial cities, ₹28,602 crore, 10 states, 6 corridors [2].
• Location pairs: Dholera SIR – Gujarat; AURIC (Shendra–Bidkin) – Maharashtra; Vikram Udyogpuri – near Ujjain, Madhya Pradesh [2].
• Firsts: the first modern cotton mill was in Mumbai in 1854; TISCO was set up at Jamshedpur in 1907.

Mains Points

• Location factors have shifted from raw material to market.
• Early heavy industry stuck to coal and ore in Chota Nagpur.
• Hydel and petroleum power, cheaper transport and automation have weakened the pull of coal and labour.

• Market, transport links and agglomeration economies now matter more. This explains the rise of clusters around Mumbai–Pune, Gurugram, Chennai and Bengaluru.

• Regional imbalance and policy response.

• Industry has concentrated in a few western and southern states and big metros.
• The government responds with regional policy: earlier, public-sector plants in backward areas; now, NICDP corridors with plug-n-play greenfield cities linked to PM GatiShakti multi-modal transport [2].

• Challenges remain: land acquisition, slow occupancy of nodes, and the risk of new clusters forming only along existing growth belts.

• The MSME definition affects industrial geography.

• Higher composite limits (2020, 2025) let small units grow without losing their benefits [3][4].

• This supports dispersed, labour-intensive clusters such as Tiruppur, Ludhiana and Moradabad, but may also let larger firms claim support meant for very small units.

• The cooperative model in rural industrialisation.

• Strengths: farmers own the unit, middlemen are removed, and the factory has an assured supply of perishable inputs (Amul, Maharashtra sugar).
• Weaknesses: political capture, mismanagement and losses in some sugar cooperatives.
