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
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) Material index=
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 • M= lake (120+120)x$0.5x2+land (118)x$1x2 + land (176)x$1x4+ land(118)x$1x4 • =$1652
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
Exercise • Total Transport Cost • A = $1016+$238=$1254 • B = $944+$118=$1062 • C = $508+$294=$802 • M=$1652+$0=$1652

Labour • Spatial mobility of labour • industrial mobility of labour • structure of labour cost - wages, holiday, fringe benefit, training cost • other than cost, quantity and quality

Weber’s idea Freight rate Real world Haulage cost Terminal cost Distance Transport cost/freight rate • Structure of transport cost
Freight rate Real world Distance Taper off rate Diminishing marginal transport cost
$ $ R.M. distance Market Effect of Taper off rate Assembly cost Distribution cost
Road/truck Rail Freight rate Water Distance Different modes of transport
Break of bulk/Transhipment point • A point where there is a need to change mode of transport due to • physical reason - port • artificial - national boundaries

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 • 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 labour TNCs shift to countries with cheap labour
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 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 Factors Causes Strategic reasons Economic reasons Political reasons Social reasons Ways provision of infrastructure provision of land redistribution of population
