Exploring Tertiary Economic Activities: Services, Transportation, and Central Place Theory

This text delves into the nature of services as a crucial component of tertiary economic activities. It distinguishes between different types of services—consumer, business, public, retail, and personal—and explores the evolving landscape of labor, highlighting bifurcated wages and the rise of “pink-collar” jobs. Additionally, it examines Central Place Theory, discussing service distribution patterns, market areas, and the importance of accessibility in economic development. Transportation geography is analyzed for its role in enabling economic activities and the impact of technology on mobility and landscape.

  1. Class 13a: Services and transportation Tertiary economic activity Central place theory Transportation geography Air pollution

  2. What are services? • No tangible product • “Leftover” economic activity • Consumer vs. business vs. public • Retail vs. personal • Producer vs. transportation

  3. What are services? • Bifurcated wages, skills • Labor more important, but fewer unions • More women (“pink-collar” workers) • Tertiary, quaternary, or quinary

  4. Where are services? • From local to global • More developed = more service jobs • “Post-industrial” economies

  5. Central place theory • How are services distributed? • Why does a regular pattern exist? • How are large and small cities connected? • Central place: market center for region

  6. Central place theory • Range: how far are you willing to travel for a service? • Threshold: how many customers do you need? • Assume shortest distance possible • Threshold < range • Market area, not city size, matters

  7. Central place theory • Hexagonal market areas • Cover all space • No overlap • First order: largest threshold and range • Second order, etc.

  8. Central place theory • Accessibility based on time, not distance • Administrative principle • Political boundaries affect consumers • Lower taxes, more permissive rules

  9. So what? • Model for regional development • Explains decline as well as growth • Neighborhood or city scale • The point is not the hexagons, but the hierarchy and interconnectedness of places

  10. Transportation • Enables all other economic activity • Derived demand • Important in its own right • Accessibility: existence of opportunities • Mobility: ability to get there • Equity of accessibility and mobility

  11. Transportation geography • Shrinking distance • Changing technology • Changing accessibility and mobility • Impact on landscape

  12. Transportation geography • New technology: container shipping • No break-of-bulk • Less labor needed • Less “slippage” • Concentration on a few ports
