# Industrial location & economic geography

Industrial location theory (Weber, Lösch) and its application to India's industrial regions, policy, and economic geography for UPSC GS-1 and Prelims.

## Why industrial location is a discipline, not an accident

Industries do not settle randomly; they minimise costs against transport, labour, and agglomeration forces. The foundational model is Alfred Weber's *Theory of the Location of Industries* (1909), which fixes plant location at the point of least total transport cost, modified by labour cost and agglomeration economies. Weber's **Material Index (MI)** = weight of localised raw materials ÷ weight of finished product. Where MI > 1 (weight-losing materials such as iron ore, sugarcane), industry locates near raw materials; where MI < 1 (weight-gaining or ubiquitous inputs such as soft-drink bottling), it locates near the market. Weber's *isodapanes* map equal additional transport cost, and a plant shifts away from the least-transport-cost point only if labour or agglomeration savings exceed the isodapane crossed.

## From Weber to von Thünen and Lösch

Johann Heinrich von Thünen's *Der isolierte Staat* (1826) is the parent model of agricultural and economic geography, deriving concentric land-use rings around a market from transport cost and land rent—still tested as the origin of bid-rent theory. August Lösch's *The Economics of Location* (1940) generalised the picture into hexagonal market areas and the demand-side determination of location, anchoring **central place theory** alongside Walter Christaller's *Die zentralen Orte in Süddeutschland* (1933), with its k=3 (marketing), k=4 (transport), and k=7 (administrative) principles. UPSC has drawn on Christaller's hierarchy and threshold/range concepts in settlement-geography questions.

## Classical location factors

Standard exam factors are: **raw materials** (iron and steel near coal–ore junctions—Jamshedpur, 1907, by TISCO at the Subarnarekha–Kharkai confluence near Gorumahisani ore); **power** (aluminium smelting near hydel/captive power—NALCO at Angul); **transport** (break-of-bulk at ports—Mumbai, Chennai cotton/petrochemical clusters); **labour** (cotton textiles in Ahmedabad and Mumbai); **market** (cotton garments, automobiles—Gurugram, Chennai); **capital and entrepreneurship**; and **water** (iron and steel, paper). Footloose industries—electronics, IT—are weakly tied to materials and orient to skilled labour and infrastructure, explaining Bengaluru's rise. Agglomeration economies (shared suppliers, labour pools, knowledge spillovers) explain industrial clustering, while deglomeration (congestion, land cost) drives dispersal to satellite towns.

The Indian state has actively shaped location through policy: the **Industrial Policy Resolutions of 1948 and 1956** (the latter creating Schedules A/B/C and the public-sector dominance of steel, heavy machinery), the establishment of steel plants at Bhilai (1955, USSR), Rourkela (1959, West Germany), and Durgapur (1959, UK), Special Economic Zones under the **SEZ Act 2005**, and the **National Manufacturing Policy 2011** targeting a 25% manufacturing share of GDP. Candidates must read theory and Indian application together.
