Core Region
Not Started

A region with extensive capital, infrastructure, skilled labor, advanced technology, large markets, and strong control over investment and production

Semiperipheral Region
Not Started

An industrializing region with substantial manufacturing and infrastructure but less global economic control than the core

SPS-7.BSPS-7.B.2

SPS-7.BSPS-7.B.2
Resource-Oriented Industry (Material-Oriented Industry)
Not Started

An industry that locates near raw materials because they are fixed, bulky, heavy, perishable, or costly to transport

SPS-7.BSPS-7.B.2
Bulk-Reducing Industry (Weight-Losing Industry)
Not Started

An industry whose finished product weighs less or occupies less volume than its inputs, favoring locations near raw materials

SPS-7.BSPS-7.B.2
Market-Oriented Industry
Not Started

An industry that locates near customers because its finished goods are perishable, fragile, costly to transport, or responsive to local demand

SPS-7.BSPS-7.B.2
Bulk-Gaining Industry (Weight-Gaining Industry)
Not Started

An industry whose finished product gains weight or volume during production, favoring locations near its market

SPS-7.BSPS-7.B.2
Labor-Intensive Industry
Not Started

An industry in which worker compensation accounts for a relatively large share of production costs

SPS-7.BSPS-7.B.2
Labor-Oriented Industry

Not Started

The clustering of related firms to share suppliers, infrastructure, transportation, specialized labor, services, and information

SPS-7.BSPS-7.B.2
Footloose Industry
Not Started

An industry with few transportation constraints because its inputs and outputs are lightweight, high-value, widely available, or electronic

SPS-7.BSPS-7.B.2
Least Cost Theory
Not Started

Alfred Weber’s theory that firms locate where the combined costs of transportation, labor, and agglomeration are lowest

SPS-7.BSPS-7.B.2
Locational Triangle
Not Started

Weber’s model of two resource locations and one market used to find the factory site with the lowest transportation cost

SPS-7.BSPS-7.B.2
Localized Materials vs. Ubiquitous Materials
Not Started

Localized materials occur only in particular places and exert a strong locational pull; ubiquitous materials are widely available and exert little pull
