Lecture Notes: Economic Development and Industrialization

Why are Some Countries Rich and Others Poor?

  • Central question: Why are rich countries located where they are, and why are poor countries where they are?
  • Answer: Industrialization and development of distinct economic sectors.
  • Key term: Development
    • Refers to a country's relative level of economic well-being.
    • A country's level of development is an indicator of its industrialization.

Economic Sectors

  • Primary Sector
    • Focuses on extraction of raw materials (e.g., mining, fishing, farming, logging).
    • Example: Ethiopia, characterized by mineral extraction and mining.
  • Secondary Sector
    • Focuses on processing raw materials (e.g., manufacturing).
    • Example: Timber processed into lumber for construction.
  • Tertiary Sector
    • Provides services rather than tangible goods (e.g., teaching, legal services, entertainment).
    • Example: U.S. economy largely made up of tertiary service jobs.
  • Quaternary Sector
    • Services requiring high education and expertise (e.g., research and development, high-tech industries).
  • Quinary Sector
    • Most influential economic activities (e.g., top government officials, CEOs).
    • Always found within quaternary sector.

Distribution and Development

  • Economies progress through sectors as they industrialize.
  • Countries with colonial pasts often have primary and secondary sectors.
  • Countries that were colonizers often have tertiary to quinary sectors.

Economic Models

  • Least Cost Theory (Alfred Weber)
    • Predicts geographical distribution of industrial activity.
    • Factories locate to minimize costs (distance and weight considered).
    • Bulk-Gaining Products: Locate near market.
    • Bulk-Reducing Products: Locate near raw materials.

Factors Determining Location of Economic Activities

  1. Access to Energy
    • Factories need abundant and reliable power sources.
  2. Access to Materials
    • Proximity to raw materials or break-of-bulk points (seaports, airports).
  3. Transportation
    • Proximity to major transportation hubs (impact of containerization).

Global Economic Hierarchy

  • Core Countries: High level of development, major in tertiary and higher sectors.
  • Periphery Countries: Lower level of development, primary sector dominant.
  • Semi-Periphery Countries: Characteristics of both core and periphery, rising tertiary jobs.

Conclusion

  • Industrialization and globalization have led to uneven economic development globally.
  • Spatial distribution of economic sectors and development closely linked to historical factors and industrialization.
