The secondary sector, often known as the industrial sector, plays a vital role in converting raw materials extracted from the primary sector into finished products. This sector encompasses manufacturing, construction, and energy production activities that add value to resources and contribute significantly to a nation's economic growth. The secondary sector contributes 24% of the share in the Indian economy. The topic “Secondary Sector” is one of the important topics in the UPSC/IAS 2023 Economy syllabus which is discussed in this article in detail.

What exactly is the Secondary Sector?

• The secondary sector is responsible for transforming raw materials into finished goods, adding value through various processing and manufacturing activities.
• India's secondary sector encompasses a wide range of industries, from textiles and automobiles to electronics and pharmaceuticals.
• It drives the process of industrialization, which in turn leads to job creation, technological advancement, and higher economic output.
• The secondary sector is sometimes called the industrial sector or manufacturing sector.
• The secondary sector is a significant source of employment for a large portion of the population, contributing to economic development.
• The integration of automation, data exchange, and AI-driven technologies is transforming manufacturing processes in India.
• Industries are adopting digitalization to enhance efficiency, reduce operational costs, and improve product quality.
• The secondary sector contributes to India's exports, earning foreign exchange and boosting the trade balance.
• Indian industries are becoming integral parts of global value chains, enhancing their competitiveness.
• Most economies go through a middle period of development during which the secondary sector overtakes the primary sector in terms of production and employment, while the primary sector declines in prominence.
• India, on the other hand, is an exception in that we have jumped right into developing the services industry without first enhancing our industrial capabilities.

Classification of Industries

Manufacturing industries are classified on the basis of their output/products, ownership, size and inputs/raw materials.

• Industries Based on Size
• Industries Based on Inputs/Raw Materials
• Industries Based on Ownership

Industries Based on Size

1) Household Industries or Cottage Manufacturing

• Household Industries or Cottage Manufacturing is the smallest unit of production. The artisans manufacture everyday things in their homes with the support of family members or part-time labour, using local raw materials and modest tools.
• The finished products may be used in the same household, sold in local (village) marketplaces, or bartered.
• As this type of production has a limited commercial significance and most of the tools are designed locally, capital and transportation have little influence.

2) Small Scale Manufacturing

• Small-scale manufacturing differs from household businesses in terms of production processes and location (a workshop outside the producer's home/cottage).
• Local raw materials, simple power-driven machines, and semi-skilled labour are used in this sort of manufacturing.
• It creates jobs and boosts the purchasing power of the local community.
• As a result, countries such as India, China, Indonesia, and Brazil have established labour-intensive small-scale manufacturing to offer jobs for their citizens.

3) Large Scale Manufacturing

• Large-Scale Manufacturing includes a large market, different raw materials, enormous energy, specialised labour, modern technology, assembly-line mass production, and large capital.

Industries Based on Inputs/Raw Materials

1) Agro-based Industries

• The processing of raw resources from the field and farm into finished products for rural and urban markets is known as agro-processing.
• Agro-based Industries include food processing, sugar, pickles, fruit juices, beverages (tea, coffee, and chocolate), spices and oils, fats and textiles (cotton, jute, silk), rubber, etc.

2) Mineral-based Industries

• Minerals are used as a raw materials in these industries.
• Some businesses, such as the iron and steel industries, employ ferrous metallic minerals that contain ferrous (iron), whereas others, such as the aluminium, copper, and jewellery industries, use non-ferrous metallic minerals.
• Non-metallic minerals are used in a variety of industries, including cement and ceramics.

3) Chemical-based Industries

• Natural chemical minerals are employed in these industries, such as mineral oil (petroleum) in the petrochemical industry.
• Natural minerals are also used in the salt, sulphur, and potash industries.
• Wood and coal are also used as raw materials in the chemical industry.
• Chemical-based industries include synthetic fibre, plastic, and others.

4) Forest-based Raw Materials using Industries

• Many big and small goods that are used as raw materials can be found in the forests.
• Forests provide timber for the furniture industry, wood, bamboo, and grass for the paper industry, and lac for the lac industries.

5) Animal-based Industries

• Animals provide leather for the leather industry and wool for woollen goods.

Industries Based on Ownership

1) Public Sector Industries

• Governments own and oversee the public sector industries.
• There are a number of Public Sector Undertakings (PSUs) in India.
• Many state-owned industries exist in socialist countries.

2) Private Sector Industries

• Public Sector Industries are generally owned by individual investors.
• Private organisations will be in charge of these.
• The majority of industries in capitalist countries are privately owned.

3) Joint Sector Industries

• Joint Sector Industries are controlled by joint-stock corporations, or the private and public sectors collaborate to create and operate them.

Factors Affecting Industrial Locations

Modern manufacturing has flourished in a small number of locations that account for less than ten per cent of the worldwide geographical area. As the goals of the corporation are to maximise profits, industry locations are frequently chosen in such a way that production expenses are kept to a minimum. The following are the factors that determine industrial location:

Access to Market

• The most essential factor in the location of industries is the existence of a market for manufactured goods.
• People who have a demand for these things and also have the purchasing power (ability to buy) to buy from the vendors at a location are referred to as "market."
• Small markets can be found in remote places where only a few people live.

Access to Raw Material

• Industries should employ low-cost, easy-to-transport raw materials.
• Steel, sugar, and cement businesses, for example, are dependent on inexpensive, bulky, and weight-losing material (ores) and are located near raw material sources.

Access to Labour Supply

• Industry location is influenced by the availability of labour. Some manufacturing processes still require expert labour.
• Industrial processes have become more mechanised, automated, and flexible as a result of increased mechanisation, automation, and flexibility.

Access to Sources of Energy

• Industries that consume more energy, such as the aluminium sector, are placed near the source of energy.
• Although coal was once the primary source of energy, hydroelectricity and petroleum are now key sources of energy for a variety of businesses.

Access to Transportation and Communication Facilities

• For the development of industries, quick and effective transportation infrastructure are required to deliver raw materials to the plant and finished items to the market.
• The cost of transportation has a significant impact on where industrial units are located.

Government Policy

• Governments implement regional policies in order to foster 'balanced' economic development and, as a result, establish industries in specific areas.

Access to Agglomeration Economies/ Links between Industries

• Nearness to leading industry and other industries benefits several industries.
• Agglomeration economies are the name given to these advantages.
• Savings are obtained through the interconnections that exist between various sectors.
