Primary Sector:

In India, the first Sector of the Economy primary  relies heavily on abundant natural resources to produce goods and carry out various processes. The services within this sector rely entirely on these natural resources' availability to ensure smooth day-to-day operations. The primary sector involves companies engaged in the extraction and harvesting of natural resources from the Earth, as well as the processing and packaging of raw materials. This sector encompasses activities such as:
  • Mining and quarrying
  • Fishing
  • Agriculture
  • Forestry
  • Hunting
In emerging economies, a significant portion of economic activity and employment is concentrated in the primary sector. However, machinery and technology play a more prominent role in primary sector activities in more advanced economies, resulting in a smaller share of total employment.

Secondary Sector:

The economy within this sector relies on natural ingredients, which are essential for creating the services and products offered, ultimately consumed by consumers. This sector is the top performer in adding value to products and services. The secondary sector comprises processing, manufacturing, and construction companies that produce goods from raw materials obtained from the primary sector. Activities in this sector include:
  • Automobile production
  • Textile manufacturing
  • Chemical engineering
  • Aerospace
  • Shipbuilding
  • Energy utilities

Tertiary Sector:

This sector holds the largest share of India's GDP contribution. It predominantly represents the service sector and is crucial in developing the other two sectors. Similar to the previous sector, it adds value to products. Moreover, it employs 23% of the total workforce in India. The tertiary sector consists of companies providing services to businesses and consumers. These services include:
  • Retail sales
  • Transportation
  • Restaurants
  • Tourism
  • Insurance
  • Banking
  • Healthcare
  • Legal services

Quaternary Sector:

The quaternary sector of the economy encompasses economic activities associated with the intellectual or knowledge-based economy. This includes information technology, media, research and development, and knowledge-based services like consultation, entertainment, broadcasting, and telecommunication. Additionally, it involves information-based services such as information generation and sharing. Some definitions also include pure services like those in the entertainment industry, media, culture, and government, which may further be classified into a quinary sector. The term reflects the three-sector model of the economy, where the primary sector provides raw materials to the secondary sector for goods production, which are then distributed to consumers by the tertiary sector. The quaternary sector encompasses companies involved in intellectual activities and technological innovation. Traditionally part of the tertiary sector, firms in the quaternary sector now focus on:
  • Research and development
  • Information technology
  • Education
  • Consulting services
These firms leverage information and technology to drive economic development and improve processes.

Sector vs. Industry

In economic terms, Sectors of the Economy have broad segments of an economy, each comprising numerous companies, while industries delineate more focused subsets within specific sectors. Consequently, industries emerge from segmenting sectors into distinct and specialised groupings. Sectors typically denote large clusters of companies with similar business activities, whereas industries entail narrower categories representing companies engaged in more specific lines of business. Sectors of the Economy often have companies that may not directly compete with one another, whereas industries typically comprise corporations in direct competition. For instance, companies like Exxon and Chevron are direct competitors in the oil and gas industry. Despite operating in the primary sector through natural resource extraction, Exxon and Chevron are unlikely to compete with agricultural companies despite falling within the same primary sector classification.

Are Sector And Industry Are Interconnected?

Sector and industry are concepts related to economics and finance, but they differ.
  • Sector : In economics, a sector is a broad category encompassing a group of related economic activities. Sectors of the Economy are typically divided based on the type of goods or services produced and the nature of the economic activity. The three primary sectors are the primary sector (which includes agriculture, forestry, fishing, mining, etc.), the secondary sector (which includes manufacturing and construction), and the tertiary sector (which includes services such as retail, healthcare, finance, etc.). Some economies may further categorise sectors into quaternary and quinary sectors, representing knowledge-based and specialised services, respectively.
  • Industry : An industry, on the other hand, is a more specific subset within a sector. It represents companies or businesses engaged in similar or related economic activities. Industries are typically defined by the products or services they produce, and they often involve similar production processes, technologies, and market dynamics. For example, the manufacturing sector has industries such as automotive, electronics, textiles, and pharmaceuticals.
