Chapter 05 – Industries Notes
Industrial activities are divided in three sectors – Primary sector, Secondary sector and tertiary sector.
The industry is an economic activity responsible for delivering us valuable finished goods that we use in our daily lives. For example, even the smallest of things, a pencil or paper has to go through more than one type of industry to develop into a finished product. Read below to know more about the classification and significance of industries.
A. Importance of Manufacturing
i. Industries add value to raw materials and turn them into usable finished products.
ii. Industries help to modernize the primary sector as it assists in creating jobs in the secondary and tertiary sectors.
iii. It reduces poverty and unemployment rates.
iv. Manufacturing industries boost trade and commerce, which brings in foreign exchange.
v. It contributes to the progress of the country by improving the economy.
B. Factors affecting location of industries:
Location : The location of an industry is affected by the availability of several things—
i. Capital: How much capital can be gained after investment and how much capital will be required to sustain the business in the location - all of these factors determine the location which will require the least capital, most favourable for industrial development.
ii. Raw Material: If the location has raw materials easily available, it is ideal for the industries as raw materials form the backbone of any industry.
iii. Market: The location should have a booming market nearby so the industries can sell their products easily. These markets should have both national and international connections.
iv. Government Policies: The government-made rules and regulations regarding imports, exports, and other traffic also determine the location of an industry.
v. Power: This refers to the availability of electricity in that location. Power is essential for industrial machinery to function and produce goods. Uninterrupted power increases the productivity of the factory.
vi. Labour: Cheap labour should be readily available to work in the industry. The workforce is necessary to operate its machines and also to oversee the administrative work.
In generation, the availability of raw material, land, water, labour, power, capital, transport and market are the factors and market are the factor affecting the location of industries. Industrialisation leads to development and growth of towns and cities. Before setting up of any industry proper assessement is done by authorities and then it is permitted. In this era when global warming is occuring at faster pace, much attention is to be given to environment aspect.
C. Industrial System:
- An industrial system consists of inputs, processes and outputs.
- Raw materials, labour and costs of land, transport, power and other infrastructure are the inputs.
- The processes include a wide range of activities that convert the raw materials into finished products.
- The result or the outputs are the end of product and income earned from it.
- Industrial set ups also depends on the political will.
D. Industrial Regions:
- Industrial regions emerge when a number of industries locate close to each other and share the benefits of their closeness.
- Major industrial regions tend to be located in the temperate areas, near sea ports and especially near coal-fields.
- Major industrial regions of the world are eastern North America, western and Central Europe, eastern Europe and eastern Asia.
- Industrial regions depends on technological advancement of a country too.
- Now industrial corridors are being set up by countries to utilise maximum potential. China-India economic corridor is one of the such examples.
E. Distribution of Major Industries:

1. Classification of Industries
There are several grounds on which industries are classified. Based on raw materials, industries can be classified into the following types:
a. Agro-Based Industries: Here plant and animal-based products serve as raw materials to produce finished products. For instance, food processing, dairy products, vegetable oil, cotton textile industries, etc.
b. Mineral-Based Industries: These primary industries involve the usage of ores of various minerals as their raw materials. Finished goods from these industries are used as raw materials for other industries. For instance, iron, an outcome of mineral-based industry, is used to make heavy machinery, tools, etc.
c. Marine-Based Industries: These industries use products obtained from the oceans and seas as raw materials. For instance, industries that process seafood or manufacture fish oil.
d. Forest-Based Industries: These are industries employing forest produce as raw material. For instance, pulp and paper, pharmaceuticals, furniture industries.
ii. Based on capital investment, industries are of the following types:
a. Small Scale Industries: These are industries using a lesser amount of capital and technology. For example, silk weaving and food processing industries.
b. Large Scale Industries: These are industries involved in the production of large volumes of products as the investment of capital is higher and the technology used is superior. For example, automobiles production and heavy machinery industries.
iii. Based on ownership, industries are of the following types:
a. Public Sector Industries: These are industries that are owned as well as operated by the government. For example, Hindustan Aeronautics Limited.
b. Private Sector Industries: These are industries that have individuals or a group of individuals owning and operating them. For example, ITC Limited and Reliance Industries Limited.
c. Joint Sector Industries: These are industries owned and operated both by the state and individuals or a group of individuals. For example, Maruti Udyog Limited.
d. Cooperative Sector Industries: These are industries that are under the ownership and operation of producers or suppliers of raw materials, workers, or both. For example, AMUL, Sudha Dairy, etc.
2. Explainations of each type of industries
