Sectors of Economy — UPSC Mains Model Answer

Agriculture employs roughly half of India's workforce while contributing under 20% to GDP, reflecting low labour productivity in the primary sector. In contrast, developed economies have transitioned the bulk of their workforce into secondary and tertiary sectors, where value addition per worker is substantially higher. This divergence is a defining feature of India's incomplete structural transformation.

India's services sector contributes over 50% to GDP and employs more workers than the secondary sector, yet this growth is concentrated in high-skill segments such as IT and finance, bypassing low-skilled rural migrants. The secondary sector, particularly manufacturing, has failed to absorb surplus agricultural labour at the scale seen in East Asian development models.

Schemes promoting labour-intensive manufacturing, skill development, and rural non-farm employment aim to bridge this gap. However, inadequate infrastructure, rigid factor markets, and low human capital formation slow the pace of workforce transition from primary to higher-productivity sectors.

A large portion of agricultural employment masks disguised unemployment, where marginal productivity of labour approaches zero. Effective land consolidation, contract farming frameworks, and agri-value chain investment are necessary to release this latent labour productively into industry and services.
