(i) Discuss the significance and growth of the service sector in modern economic development.
Answer
Services are usually defined as ‘activities’ which are relatively detached from material production and hence are not directly involved in the processing of physical materials.
• Services are an important part of modern economic development which include health, education, law, governance and recreation etc.
• Services are provided to individual consumers who can afford to pay for them. Many services have now been regulated with the growth of population. Making and maintaining highways and bridges, maintaining fire fighting departments and supplying or supervising education and customer -care are among the important services most often supervised or performed by governments or companies.
• State and union legislation have established corporations to supervise and control the marketing of such services as transport, telecommunication, energy and water supply.
• Professional services are primarily health care, engineering, law and management. The location of recreational and entertainment services depends on the market.
• Today most people are service workers. Services are provided in all societies. But in more developed countries a higher percentage of workers is employed in providing services as compared to less developed countries.
• The trend in employment in this sector has been increasing while it has remained unchanged or decreasing in the primary and secondary activities.
