Abstract: | The importance of service sector in terms of its share in national income/GDP has been growing progressively in Indian economy throughout the post independence period. The objective of this paper is to make an assessment of the importance of the service sector which accounts the value added originating from service sector in total value added produced, needed directly and indirectly to produce gross output in Indian economy during the period 1968–69 to 1993–94. For this purpose, an index of vertical integration has been constructed which provides a dimension-free measure of the multiplier of each industry on the value-added originating from the service sector to total value added. Empirical part of this study shows that Trade, Other services, Electricity, Railway Transport Services, Chemicals and Construction played a role of key sector in terms of importance of Service sector as input for their production throughout the study period of the Indian economy. They provided strong stimulus to the economy by inducing greater value addition to service sector. In general, services industries appear to be the highly growth- inducing sector in so far as it helps higher value addition to other industries. |
