Key concepts

Manufacturing and manufacturing industry

NCERT section Manufacturing

Manufacturing covers everything from handicrafts to moulding iron and steel, stamping plastic toys, or assembling computer parts and space vehicles. Common characteristics: application of power, mass production of identical products and specialised labour in factories producing standardised commodities.

• It may use modern power and machinery or remain primitive; many Third World countries still 'manufacture' in the literal sense.

'Manufacturing' vs 'manufacturing industry' (box):

• Manufacturing literally means 'to make by hand', but now includes goods made by machines: transforming raw materials into finished goods of higher value for local or distant markets.
• An industry is a geographically located manufacturing unit keeping books of accounts and records under a management system.
• Since 'industry' is also used for activities not carried on in factories (the entertainment and tourism industries), the longer phrase 'manufacturing industry' is used for clarity.

Worked example

What is manufacturing? Why is the term 'manufacturing industry' preferred? (3 marks)

Try it first, then show the solutionSolution

1. Manufacturing originally meant making by hand but now includes machine-made goods: transforming raw materials into finished goods of higher value for sale.
2. Its common features are use of power, mass production of identical products and specialised labour in factories.
3. Because 'industry' is also used for non-factory activities like entertainment and tourism, 'manufacturing industry' is used for clarity.

Answer: Value-adding transformation of raw materials; 'manufacturing industry' distinguishes it from service 'industries'.

Characteristics of modern large-scale manufacturing

NCERT section Characteristics of Modern Large Scale Manufacturing

1. Specialisation of skills/methods: the craft method makes a few made-to-order pieces, so costs are high. Mass production makes large quantities of standardised parts, each worker doing one task repeatedly.

2. Mechanisation: using gadgets to do tasks. Automation (no human thinking needed during production) is its advanced stage; automatic factories with feedback and closed-loop computer control have machines that 'think'.

3. Technological innovation: research and development for quality control, removing waste and inefficiency, and combating pollution.

4. Organisational structure and stratification: complex machine technology, extreme specialisation and division of labour to produce more with less effort and cost; needs vast capital, large organisations and executive bureaucracy.

5. Uneven geographic distribution: major concentrations in a few places, covering less than 10 per cent of world land; these nations became centres of economic and political power. Manufacturing sites occupy far smaller areas than agriculture because of greater intensity: 2.5 sq km of the American corn belt has about four large farms with 10-20 workers supporting 50-100 people, while the same area could hold several integrated factories employing thousands.

Worked example

Explain any three characteristics of modern large-scale manufacturing. (3 marks)

Try it first, then show the solutionSolution

1. Specialisation: mass production of standardised parts, each worker repeating one task, unlike costly made-to-order craft production.
2. Mechanisation and automation: gadgets do tasks; automatic factories use feedback and closed-loop computer control.
3. Technological innovation: research and development for quality control, removing waste and fighting pollution (also: vast capital and bureaucracy; uneven distribution).

Answer: Specialisation, mechanisation/automation and R&D-based innovation (plus large organisations and uneven distribution).

Factors influencing industrial location

NCERT section Why do Large-scale Industries choose different locations?

Industries maximise profits by reducing costs, so they locate where production costs are minimum.

1. Access to market (most important): a market means people with demand and purchasing power. Remote, thinly peopled areas offer small markets. Europe, North America, Japan and Australia are large markets because of high purchasing power; densely populated South and South-east Asia also provide large markets. Aircraft and arms industries have global markets.

2. Access to raw material: should be cheap and easy to transport. Industries using cheap, bulky, weight-losing materials (ores) locate near the source: steel, sugar, cement. Perishability also pulls industry to the source: agro-processing and dairy.

3. Labour supply: some manufacturing still needs skilled labour; but mechanisation, automation and flexible processes have reduced dependence on labour.

4. Sources of energy: power-hungry industries locate near energy, e.g. aluminium. Coal was once the main source; now hydroelectricity and petroleum also matter.

5. Transport and communication: fast, efficient transport for raw materials and finished goods; transport cost shapes location. Western Europe and eastern North America have highly developed transport, inducing concentration. Better transport led to integrated development and regional specialisation. Communication is needed to exchange and manage information.

6. Government policy: 'regional policies' promote balanced development by setting up industries in particular areas.

7. Agglomeration economies: benefits from nearness to a leader industry and other industries; savings come from linkages.

These factors operate together.

Worked example

Why are steel, sugar and cement industries located near raw materials, while some industries locate near markets? (3 marks)

Try it first, then show the solutionSolution

1. Steel, sugar and cement use cheap, bulky and weight-losing raw materials, so transporting them is costly; locating near the source cuts costs.
2. Perishable inputs (sugarcane, milk) also pull industries to the source.
3. Industries whose products are in demand among people with purchasing power locate near markets, the most important locational factor.

Answer: Weight-losing or perishable inputs favour raw-material locations; demand and purchasing power favour market locations.

Footloose industries

NCERT section Foot Loose Industries

Footloose industries can be located in a wide variety of places.

• Not dependent on any specific raw material, weight-losing or otherwise.
• Depend largely on component parts obtainable anywhere.
• Produce in small quantities and employ a small labour force.
• Generally non-polluting.
• The important locational factor is accessibility by road network.

Contrast: sugar, cotton textiles and vegetable oils are not footloose because they depend on specific (often perishable or bulky) raw materials.

Worked example

What are footloose industries? (3 marks)

Try it first, then show the solutionSolution

1. Industries that can be located in a wide variety of places, as they do not depend on a specific raw material.
2. They use component parts available anywhere, produce small quantities and employ few workers.
3. They are generally non-polluting, and their key location factor is accessibility by road.

Answer: Flexible-location, component-based, small, non-polluting industries tied mainly to road access.

Classification by size

NCERT section Industries based on Size

Size depends on capital invested, number of workers and volume of production.

1. Household or cottage manufacturing: the smallest unit. Artisans use local raw materials and simple tools at home with family members or part-time labour. Products for the household, local (village) markets or barter. Capital and transport matter little; low commercial significance. Products: foodstuffs, fabrics, mats, containers, tools, furniture, shoes, figurines, leather goods, pottery and bricks, jewellery, bamboo and wood crafts (e.g. pottery in Nagaland, bamboo baskets in Arunachal Pradesh).

2. Small-scale manufacturing: differs by techniques and place (a workshop outside the home). Uses local raw materials, simple power-driven machines and semi-skilled labour; provides employment and raises local purchasing power. India, China, Indonesia and Brazil developed labour-intensive small-scale industry to employ their people.

3. Large-scale manufacturing: needs a big market, many raw materials, huge amounts of energy, skilled specialist workers, advanced technology, large capital and mass production on assembly lines. Developed over the last 200 years in the UK, north-eastern USA and Europe, and has now spread almost worldwide. Industrial regions are grouped into traditional (clustered in a few developed countries) and high-technology (diffused to less developed countries).

Worked example

Distinguish between household industries and small-scale industries. (3 marks)

Try it first, then show the solutionSolution

1. Household industries are the smallest units, run at home by artisans with family labour, local raw materials and simple tools.
2. Small-scale industries operate in a workshop outside the home, with simple power-driven machines and semi-skilled labour.
3. Household products serve the family, village market or barter with little commercial significance; small-scale units provide employment and raise local purchasing power (India, China, Indonesia, Brazil).

Answer: They differ in place (home vs workshop), technique (hand tools vs power machines) and commercial role.

Classification by inputs, output and ownership

NCERT section Industries based on Inputs/Raw Materials; Output/Product; Ownership

By inputs/raw materials:

• (a) Agro-based: processing farm produce: food processing (canning, cream, fruit processing, confectionery), sugar, pickles, fruit juices, beverages (tea, coffee, cocoa), spices, oils and fats, textiles (cotton, jute, silk), rubber. Old methods like drying, fermenting and pickling had limited use before the Industrial Revolution.
• Agri-business (box): commercial farming on an industrial scale, often financed by businesses outside agriculture (e.g. large corporations in tea plantations); mechanised, large, structured, chemical-reliant 'agro-factories'.
• (b) Mineral-based: ferrous (iron and steel); non-ferrous (aluminium, copper, jewellery); non-metallic (cement, pottery).
• (c) Chemical-based: natural chemical minerals (petroleum for petrochemicals; salts, sulphur, potash); also wood and coal; synthetic fibres, plastics.
• (d) Forest-based: timber for furniture; wood, bamboo and grass for paper; lac for lac industries.
• (e) Animal-based: leather, wool for woollens, ivory from elephant tusks.

By output/product:

• Basic industries: products used as raw materials to make other goods (e.g. iron and steel used for machines that make textiles).
• Consumer goods (non-basic) industries: goods consumed directly: bread and biscuits, tea, soaps and toiletries, writing paper, televisions.

By ownership:

• Public sector: owned and managed by governments (India's PSUs; socialist countries).
• Private sector: owned by individual investors, managed privately (typical of capitalist countries).
• Joint sector: managed by joint stock companies, or by private and public sectors together.
• Mixed economies have both public and private enterprises.

Worked example

Classify industries on the basis of raw materials with one example each. (5 marks)

Try it first, then show the solutionSolution

1. Agro-based: process farm produce, e.g. sugar, food processing, cotton textiles.
2. Mineral-based: ferrous (iron and steel), non-ferrous (aluminium, copper) and non-metallic (cement, pottery).
3. Chemical-based: use natural chemical minerals or derived materials, e.g. petrochemicals, synthetic fibres, plastics.
4. Forest-based: timber for furniture; wood, bamboo and grass for paper; lac.
5. Animal-based: leather, wool and ivory.

Answer: Agro, mineral, chemical, forest and animal-based industries.

High-technology industry and technopolies

NCERT section Concept of High Technology Industry

High-tech is the latest generation of manufacturing: intensive research and development (R and D) leading to products of an advanced scientific and engineering character.

• Professional (white-collar) workers form a large share and outnumber production (blue-collar) workers.
• Examples: robotics on assembly lines, computer-aided design (CAD) and manufacturing, electronic controls of smelting and refining, and constant development of new chemical and pharmaceutical products.
• Landscape: neatly spaced, low, modern, dispersed office-plant-lab buildings rather than massive factories; planned business parks for high-tech start-ups are part of regional development schemes.
• Technopolies: regionally concentrated, self-sustained, highly specialised high-tech industries, e.g. Silicon Valley near San Francisco and Silicon Forest near Seattle.

Overall importance: manufacturing is a major part of the world economy; among its most important branches the textbook lists automobiles, electronics, petrochemicals, textiles, and iron and steel.

Worked example

Write a note on high-tech industry. (3 marks)

Try it first, then show the solutionSolution

1. High-tech is the latest generation of manufacturing based on intensive R and D, producing advanced scientific and engineering goods.
2. White-collar professionals outnumber blue-collar production workers; examples include robotics, CAD, electronic controls of smelting and new pharmaceuticals.
3. Its landscape has low, dispersed office-plant-lab buildings and business parks; concentrated clusters are called technopolies (Silicon Valley, Silicon Forest).

Answer: R&D-intensive, white-collar-dominated manufacturing in dispersed modern parks, forming technopolies.

   What is agri-business? (3 marks)

   Hint

   Agro-factories.

   Answer

   Agri-business is commercial farming on an industrial scale, often financed by businesses whose main interests lie outside agriculture, such as large corporations in tea plantations. Its farms are mechanised, large, highly structured and reliant on chemicals, and may be described as 'agro-factories'.

6. Q6 · 3 marks · Short answerHOTS / competency

   Suppose a state wants to attract industry to a backward district with no major raw materials but a new highway. Which kind of industry is most suitable and what policy could help? (3 marks)

   Hint

   Footloose; regional policy.

   Answer

   Footloose industries suit it: they do not depend on specific raw materials, use components available anywhere, employ small workforces, are non-polluting, and need mainly road accessibility, which the highway provides. The state could use a regional policy to promote balanced development by offering sites or incentives, and later agglomeration economies may develop as linked industries cluster.

7. Q7 · 3 marks · Short answerBoard level

   Explain the classification of industries based on ownership. (3 marks)

   Hint

   Public, private, joint.

   Answer

   Public sector industries are owned and managed by governments (India's PSUs; socialist countries). Private sector industries are owned by individual investors and managed privately (typical of capitalist countries). Joint sector industries are managed by joint stock companies or by private and public sectors together. Mixed economies have both public and private enterprises.

8. Q8 · 5 marks · Long answerHOTS / competency

   'Manufacturing sites are much less conspicuous than agriculture in terms of area.' Explain with the textbook example and discuss the uneven distribution of manufacturing. (5 marks)

   Hint

   Corn belt.

   Answer

   Manufacturing is far more intensive than agriculture. In the American corn belt, 2.5 sq km usually has about four large farms employing 10-20 workers who support 50-100 people; the same area could hold several large integrated factories employing thousands. So manufacturing concentrates on small areas. Globally, major concentrations of modern manufacturing occupy less than 10 per cent of the world's land, and these nations have become centres of economic and political power. Concentration is encouraged by markets, transport (Western Europe, eastern North America), energy and agglomeration economies.
