Primary Sector: When the economic activity depends mainly on exploitation of natural resources then that activity comes under the primary sector. Agriculture and agriculture related activities are the primary sectors of economy.
Secondary Sector: When the main activity involves manufacturing then it is the secondary sector. All industrial production where physical goods are produced come under the secondary sector.
Tertiary Sector: When the activity involves providing intangible goods like services then this is part of the tertiary sector. Financial services, management consultancy, telephony and IT are good examples of service sector.
During early civilization all economic activity was in primary sector. When the food production became surplus people’s need for other products increased. This led to the development of secondary sector. The growth of secondary sector spread its influence during industrial revolution in nineteenth century.
After growth of economic activity a support system was the need to facilitate the industrial activity. Certain sectors like transport and finance play an important role in supporting the industrial activity. Moreover, more shops were needed to provide goods in people’s neighbourhood.
Ultimately, other services like tuition, administrative support developed.
To understand this interdependency, let us take an example of a cold drink. A cold drink contains water, sugar and artificial flavour. Suppose if there is no sugarcane production then procuring sugar will become difficult and costly for the cold drink manufacturer. Now to transport sugarcane to sugar mills and sugar to the cold drink plant needs the services of a transporter. A person or system of persons is required to maintain and monitor all these movements of goods from farm to factory to shop in different locations. That is where role of administrative staffs comes. Let us go back to the farmer. He also needs feritlisers and seeds which are processed in some factory and need to be delivered to his doorstep by some means of transportation. Moreover, at every step of these activities we require the proper monetary and banking system. So, in a nutshell this describes how interrelated all sectors of an economy are.
Closely observe the given graphs. The first graph shows the rupee-wise turnover of various sectors in 1973 and 2003. The second graph shows the share of three sectors in the GDP during these 20 years and last graph shows share in providing employment.
The first graph shows a massive increase in turnover for all these sectors during 20 years, which shows the way our economy grew.
The second graph shows that share of agriculture decreased substantially and that of industry remained static and share of services grew. Particularly the growth of share of services sector was phenomenal from 35% to 55%.
Now the third graph paints a distressing picture. The share in providing employment was not in tune with the share in GDP. The agriculture provided employment to 75% workers and this decreased to 60% in 2000, which is not as big a drop as agriculture’s drop in GDP contribution. On the other hand, the growth in employment provided by other two sectors was substantially low.
Organised Sector: The sector which carries out all activity through a system and follows the law of the land is called organized sector. Moreover, labour rights are given due respect and wages are as per the norms of the country and those of the industry. Labour working in organized sector gets the benefit of social security net as framed by the Government. Certain benefits like provident fund, leave entitlement, medical benefits and insurance are provided to workers in the organized sector.
These security provisions are necessary to provide source of sustenance in case of disability or death of the main breadwinner of the family. Otherwise the dependents will face a bleak future.
Unorganised Sector: The sector which evades most of the laws and doesn’t follow the system comes under unorganized sector. Small shopkeepers, some small scale manufacturing units keep all their attention on profit-making and ignore their workers’ basic rights. Workers don’t get adequate salary and other benefits like leave, health benefits and insurance are beyond the imagination of people working in unorganized sectors.
Public Sector: Companies which are run and financed by the Government comprise the public sector. After independence, India was a very poor country. India needed huge amount of money to set up manufacturing plants for basic items like iron and steel, aluminium, fertilizers and cements. Additionally, infrastructure like roads, railways, ports and airports also require huge investment. In those days, Indian entrepreneur was not cash rich so government had to start creating big public sector enterprises like SAIL (Steel Authority of India Limited), ONGC(Oil & Natural Gas Commission), etc.
Private Sector: Companies which are run and financed by private people comprise the private sector. Companies like Hero Honda, Tata, etc. are from private sectors.
Government, from time to time, announces and implements various employment schemes to fight unemployment or hidden employment to help the weaker section of society. Schemes; like NREG (National Rural Employment Guarantee) is the latest announced by the UPA government in 2004. Now it is known as MNREGA (Mahatma Gandhi National Rural Employment Guarantee). This programme guarantees a minimum of 100 days of employment to at least one person from every rural household. This is part of government’s effort to ensure the ‘Right to Work’ to the rural poor citizen.
