Weber’s Model

Industrial Location

locational model
Locational Model
  • What is a model?
    • Simplified
    • representative / common key features
weber s model1
Weber’s Model
  • Aim: find out the optimum location of a factory
  • Optimum location = least cost location
  • Assumptions
    • isotropic surface / uniform plain
    • different labour cost at different locations but labour is not mobile
    • single mode of transport and transport cost is direct proportion to distance and weight
slide4

Weight of localized raw materials

Weight of finished product

  • perfect competition(same product, same quality, same price)
  • entrepreneurs are economic rational (minimize cost)
  • resources (raw materials)
    • ubiquitous (everywhere)
    • localized (fixed)
    • pure (no weight change)
    • gross (weight loss)

  • Assembly cost
  • A=land (114)x$1x4 +lake (160+120)x$0.5x4 = $1016
  • B=lake (120+120)x$0.5x2+land (176)x$1x4 = $944
  • C=lake (120+160)x$0.5x2 + land(114)x$1x2 = 508
  • M= lake (120+120)x$0.5x2+land (118)x$1x2 + land (176)x$1x4+ land(118)x$1x4

Exercise
  • Distribution cost
  • A to M = lake (120+120)x$0.5x1+land (118)x$1x1=$238
  • B to M = land (118)x$1x1=$118
  • C to M = land (176)x$1x1+land(118)x$1x1=$294
exercise2
Exercise
  • Total Transport Cost
  • A = $1016+$238=$1254
  • B = $944+$118=$1062
  • C = $508+$294=$802
  • M=$1652+$0=$1652

  • Spatial mobility of labour
  • industrial mobility of labour

  • other than cost, quantity and quality

impact of technology
Impact of technology

Production technology

use less amount of raw materials and/or power

use of substitutes (raw materials or power) e.g. use of scrap in iron and steel industry

Transport technology

lower freight rate

refrigeration

standardization(use of containers)

Automation - less labour and skilled labour

impact of information technology
Impact of Information technology
  • What are the uses of computers and internet in manufacturing?
  • Computer aided design CAD
  • Computer controlled production
  • Computer controlled logistics
    • getting raw materials, products to market
  • e-business / e-commerce
    • buying raw materials, sale of products
  • e-recruitment
impact of information technology1
Impact of Information technology
  • Impact on getting raw materials?
  • Impact on seeking labour?
  • Impact on mobility of capital?
  • Impact on transportation and logistics?
  • Impact on market?
  • Impact on industrial location?
impact of information technology2
Impact of information technology
  • Information about price and supply of raw materials is widely spread
  • More information for labour to seek employment
  • Recruitment and online interview over internet
  • Information on job vacancies is widely spread
  • Decrease the reluctance of labour to migrate to othre countries
  • Increases mobility of labour
  • Increase demand for skilled labour

TNCs shift to countries with cheap labour

impact of information technology3
Impact of information technology

Promotion of world trade

Better monitoring of investment

Mobility of capital is greater

Lean production method and Just-in-time production is possible

Industries may be shifting away from sites closed to raw materials and power resources or nodal points of transportation as the influence of transport cost is diminishing

Better flow of market information

impact of technology1
Impact of technology
  • Information technology
    • With the ease of making foreign investment, it may become more and more popular to set up new factories in other countries, especially in the less developed countries, for the sake of lowering the production cost with cheaper land and labour
    • Decrease the need to move industries to other countries for labour with special skills
    • Development of Transnational corporations / cross-border production is more common
    • Clustering / agglomeration of industries
locational change
Locational change
  • Declining importance of traditional factors
  • relative importance of other factors rise
  • more flexible / footloose
  • importance of research and development
  • market / large urban centres
  • Cross-border production / international division of labour / TNCs
behavioural factors
Behavioural Factors
  • Not all decision-makers are economic rational
  • perception , knowledge and information
  • satisficers rather than optimizers
  • psychic income
  • advantages :
    • lower rent because of weaker competition
    • reduce over-concentration-pollution, etc.
    • provide employment to inferior areas

Economic reasons

Political reasons

Social reasons

Ways

provision of infrastructure

provision of land

redistribution of population

Favourable terms of trade

e.g. Shenzhen Special Economic Zone

tax holiday / concession rate

land use planning / zoning

protection of local industries

e.g. tariff, quota

Anti-pollution laws and traffic control regulations
