NoteKey Concepts
  • Alfred Weber’s Least Cost Theory (1909): Location minimizes transport and labour costs. Weber used the Locational triangle (two raw materials, one market) to find the optimal point where Total transport cost is minimum.
    • Material Index = Weight of localized raw materials / Weight of finished product. MI > 1 = material-oriented; MI < 1 = market-oriented.
    • Isodapanes: Lines of equal total transport cost.
  • August Lösch’s Profit Maximization Theory (1954): Location where profit is maximized (total revenue minus total cost). Spatial demand cone; hexagonal market areas.
  • David Smith’s Spatial Margins of Profitability (1971): Incorporates spatial variations in both costs and revenues to find the area where profit is possible. Also known for the Area-cost curve approach.
  • Edgar Hoover: Emphasized transport cost structure (terminal vs. line-haul costs) and the concept of Delivered prices.
  • Allan Pred: Behavioural approach — bounded rationality, imperfect information in locational decision-making. His proposition suggests that the ‘Behavioral Approach’ strongly determines the location of an industry.
  • Textile Industry Location: Transportation cost does not play a major role in the location of the textile industry because the weight of cotton is more or less equal to the weight of the finished product (i.e., cotton is a pure material or weight-neutral).

Weber’s Theory of Industrial Location — Detailed (NET Notes — Pulakesh Pradhan)

Alfred Weber (1909) — *Theory of the Location of Industries

  • Location of industry determined by **minimum transport cost*
  • Three factors:
    1. Transport costs (primary factor)
    2. Labour costs (secondary factor)
    3. Agglomeration/Deglomeration (tertiary factor)

Weber’s Material Index (MI)

**MI = Weight of localised materials / Weight of finished product*

  • MI > 1 → industry locates near raw material (material oriented)
  • MI < 1 → industry locates near market (market oriented)
  • MI = 1 → industry locates anywhere (footloose)

Isodapane

  • Line joining points of equal transport cost around the least cost location
  • Critical Isodapane — isodapane where saving in labour = extra transport cost

Lösch’s Theory (NET Notes)

  • August Lösch (1954) — *“The Economics of Location”
  • Maximum profit orientation (unlike Weber’s minimum cost)
  • Hexagonal market areas for optimal spatial distribution
  • Landscape of hexagonal nets = Löschian Landscape

Manufacturing Industries

NEP-2020 Unit II — Manufacturing (Cotton Textile, Iron and Steel, Petrochemical)
UGC NET Classification of Industries; World Industrial Regions

NoteKey Concepts
  • Classification of Industries: By size (cottage, small-scale, large-scale), raw material (agro-based, mineral-based), output (basic/heavy, consumer/light), ownership (public, private, joint).
  • Iron and Steel Industry: Basic/key industry. Location historically tied to coal (Ruhr, Appalachians), later to iron ore, and currently shifting to coastal locations or markets (mini-steel plants using scrap).
  • Textile Industry: Historically labour-intensive, raw material oriented, but highly mobile today due to cheap labour search (shift from developed to developing global South).
  • Petrochemical Industry: Market or port-oriented; forms base for plastics, fertilizers, synthetic fibres.
  • World Industrial Regions:
    • East-North America: Great Lakes, Boston
    • Western and Central Europe: Ruhr, Paris
    • Eastern Europe: Volga-Ural, Ukraine
    • Eastern Asia: Tokyo, Yokohama, coastal China, South Korea
  • Knowledge Industry: A term introduced by Fritz Machlup to describe industries based heavily on knowledge and information.

Special Economic Zones and Technology Parks

Syllabus Topic Details
NEP-2020 Unit II — Special Economic Zones and Technology Parks

NoteKey Concepts
  • Special Economic Zones (SEZs): Designated geographical areas within a country with liberal economic laws (tax exemptions, relaxed labour laws, single-window clearance) intended to boost foreign direct investment (FDI), exports, and employment.
    • Example: Shenzhen (China) as a pioneer; Indian SEZ Act 2005.
  • Technology Parks / Technopoles: Centers of high-tech manufacturing and information-based quaternary industries.
    • Agglomeration economies, proximity to major universities/research centers, high-quality amenities to attract skilled workers.
    • Examples: Silicon Valley (USA), Bengaluru IT corridor (India), Cambridge Science Park (UK).
  • Impacts: Regional development engines, but can create enclaves, widen regional disparities, and cause land acquisition conflicts.

Theories and Models

Theory / Concept Propounder Description
Least Cost Theory Alfred Weber Location determined by transport costs, labor costs, and agglomeration.
Profit Maximization August Lösch Focuses on demand and market area rather than just costs.
Spatial Margin of Profitability D.M. Smith Area where total revenue exceeds total cost.
Product Life Cycle Theory Raymond Vernon Stages: New product, Maturing product, Standardized product.
Industrial Inertia - Tendency of an industry to remain in its original location even after advantages disappear.

Key Terms

  • Material Index (MI): Weight of localized raw materials / Weight of finished product.
  • Isodapane: Lines of equal total transport cost.
  • Critical Isodapane: Isodapane where labor cost savings equal additional transport costs.
  • Agglomeration: Benefits from shared infrastructure and proximity to other firms.
  • Deglomeration: Disadvantages (congestion, high rent) leading to industrial dispersal.
