Weber’s Model

Industrial Location

Locational Model

• What is a model?

– Simplified– representative / common key

features

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

– 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)

Material index=Weight of localized raw materialsWeight of finished product

Procedures for finding optimum location

• Stage 1 - Least Transport Cost

• Stage 2 - add in Labour Saving

• Stage 3 - add in Agglomeration Economies

Exercise• 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

Impact of technologyProduction 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 technologylower freight rate

refrigerationstandardization(use of containers)

Automation - less labour and skilled labour

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 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 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 labourTNCs shift to countries with cheap labour

Impact of information technologyPromotion of world tradeBetter monitoring of investmentMobility of capital is greaterLean production method and Just-in-time

production is possibleIndustries 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 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• 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• 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

Institutional FactorsCauses

Strategic reasonsEconomic reasonsPolitical reasonsSocial reasons

Waysprovision of infrastructureprovision of landredistribution of population

Favourable terms of trade

e.g. Shenzhen Special Economic Zone

tax holiday / concession rate

land use planning / zoningprotection of local industries

e.g. tariff, quota

Anti-pollution laws and traffic control regulations
