Types of Industries – Primary, Secondary & Tertiary?


If you have ever engaged in a conversation about the economy or progress of a country, then you might have heard the word ‘industry’ being thrown around quite often. This is because a country’s industrial operations serve as an important benchmark to gauge the level of economic growth in it. But this begs the important question, what exactly is an industry? Is it any different from a ‘sector’? 

The industry is essentially a cumulation of all the companies and enterprises engaging in similar work. These too can be categorized into three, more about which is enumerated later in this article. On the other hand, a sector covers a broader definition of business operations. It comprises several industries and breaks the overall economy into sub-categories. 

Primary Industries

Primary industries comprise those industries wherein the business processes require minimal value addition. It primarily contains operations in which raw materials are extracted from their primal state and processed for secondary industries. The scale of operations in these industries is generally moderate to large since removing raw materials from their core state requires large working capital. These primary industries can also be further classified into sub-categories based on their core functionalities. 

Primary Industry Classification

  • Extractive industries: – Extractive industries are those enterprises that engage in activities concerned with extracting and removing raw materials from their rudimentary state. This includes operations such as removing minerals from their ores, mining coal, petroleum, etc. The presence of such industries is largely visible in underdeveloped and developing countries. 
  • Genetic industries: – This category of industries is involved in operations that focus on processing raw materials to generate some form of enhancement. The raw materials go through various levels of manufacturing, which require a huge amount of scientific and technical research. Livestock, agriculture and fishing industries are some major examples of genetic industries. 

Secondary Industries 

Secondary industries engage in slightly high-level operations when compared to their primary counterpart. These industries direct their resources towards converting the products produced by primary industries into usable consumer or producer goods through manufacturing and processing. The production of capital products is generally done in this industrial type. Since secondary industries encompass such a wide range of business processes, it helps to understand their totality by dividing them into further categories. 

Secondary Industries Classification

  • Manufacturing industries: – In manufacturing industries, the primary function performed is that of converting raw materials into finished finish-consumer or producer goods through multiple rounds of processing and value addition. These enterprises generally function at a large-scale level. 
  • Construction industries: – Construction industries are concerned with all the operations relating to the construction, building, and development of the infrastructural framework. The business processes utilize raw materials and combine them with other resources in order to develop roads, buildings, structures, and much more. 
  • Light industries: – Light industries comprise those business enterprises that follow a relatively low scale of production. They generally produce durable-use consumer goods. Light industries require lesser working capital, cause low pollution levels and even have a lower electricity consumption rate. 
  • Heavy industries: – Heavy industries are categorized based on the large volume of operations that are conducted. They generally produce capital and producer goods, which weigh a lot and require high levels of manufacturing. Contrary to light industries, these enterprises require a higher degree of power and cause a higher level of pollution. 

Tertiary Industries 

Tertiary industries are quite different from their counterparts since it does not deal with manufacturing or procuring goods in any form. Rather, this industry focuses on intangible services which generate gains and income. Services like consulting, health, professional services, franchises, and more constitute this type of industry. Service industries play a pivotal role in the economy since they offer employment to a huge portion of the population in our country. 

Since tertiary industries encompass a wide variety of services, give below are some of the major industrial groups that come under its purview.

In the age of digital retail and e-commerce, the industry of marketing services is gaining quite a bit of traction. It consists of services relating to the spread of awareness and information regarding products and startups. This process can be quite extensive, given the number of competitors and type of product. Advertising forms a major chunk of the marketing services industry, along with other media-based services that allow business owners to spread the word about their services.

Numerous enterprises, such as legal houses, consultants, etc., come under the legal industry, and it contributes to a good portion of the business transactions in the country.

Here is a brief differentiation of the three main types of industries for a better understanding of the same:

Secondary industries perform the function of converting and processing raw materials into usable goods.

Tertiary industries provide services that are intangible in nature.
