Housing, Construction and Allied Industries as an Engine of Indian Commerce: A Conceptual Review of Demand Linkages, Investment and Labour

Abstract

This conceptual review examines the role of housing, construction and their allied industries in Indian commerce, treating the sector as a demand-linked cluster rather than a single industry. Adopting an integrative literature review design, the study synthesises 24 scholarly and institutional sources, comprising foundational theory on multipliers, inter-industry linkages and surplus labour, international evidence on construction and economic development, and India-focused studies and official reports on housing, macroeconomic trends and construction labour, through thematic analysis. Four themes emerge: construction as a component of aggregate demand with strong backward linkages; housing as the demand anchor of the cluster, sustained by a large and persistent urban shortage; the allied industries of cement, steel, paints, fittings and housing finance whose fortunes move with construction activity; and the sector's dual role as the largest non-farm absorber of labour and a site of informality and precarity. The synthesis is organised into a Demand–Linkage–Labour framework and five research propositions. The paper argues that the commercial significance of the sector lies as much in the industries it pulls along and the workers it absorbs as in its own output, and that policy and business strategy should treat it accordingly. Implications are offered for firms in the cluster, financial institutions and policymakers.
