54-1 Main Economic Sectors and Their Distinct Development Patterns

Economic Sectors
  • Definition: Economic sectors are groupings of industries based on what is produced and the activities of the workforce.
  • Categories: Geographers categorize economic activities into five broad categories known as economic sectors:
      - Primary Sector
        - Definition: Industries that extract natural resources from the environment, commonly referred to as extractive industries.
        - Examples: Fishing, hunting, farming, logging, oil extraction, quarrying, mining.
        - Types of Natural Resources:
          - Renewable resources (e.g., timber)
          - Nonrenewable resources (e.g., coal)

      - Secondary Sector
        - Definition: Industries that process raw materials from the primary sector and transform them into finished, usable products.
        - Examples: Ore being converted to steel, logs milled into lumber, fish processed and canned.
        - Subcategories:
          - Light Industry: e.g., furniture manufacturing.
          - Heavy Industry: e.g., automobile manufacturing.

      - Tertiary Sector
        - Definition: Industries that provide services to businesses and consumers including the transportation and delivery of goods.
        - Examples: Checkout clerks, lawyers, college professors.
        - Subtypes:
          - Transportation/communication services
          - Producer services
          - Consumer services

      - Quaternary Sector
        - Definition: Sector dedicated to intellectual and informational services, including scientific research and development.
        - Examples: Computer software development, biomedical research leading to new technologies.

      - Quinary Sector
        - Definition: Highest-level management decisions in business, government, education, and science.
        - Example: CEOs overseeing decisions on investment, research in a software firm.
Patterns of Economic Development
  • Hierarchy of Economic Development:
      - Primary sector economies are considered least developed; secondary and tertiary sectors indicate increasing complexity and advancement.
      - A strong secondary sector suggests more development than a primary sector-centric economy.
      - The emergence of the tertiary sector signifies economic growth as a service sector develops to support manufacturing and consumer needs.
  • Proportion of Sector Workforce:
      - Ranking of economic advancement can be assessed by workforce distribution: 10-20-70 (primary-secondary-tertiary) vs. 40-40-20.
      - The declining importance of primary sector skills emphasizes a shift toward secondary and tertiary sector engagement.

National Economic Core Areas

  • Geographically Uneven Development: Evolved with industrialization, exemplified by the steelmaking industry.
  • Core and Peripheral Areas:
      - Core Area: Dominated by manufacturing industry; surrounds natural resource sources in peripheral areas.
      - Base Industry: Defined as industries that drive the economy's growth and on whose success others rely (e.g., steelmaking).
      - This leads to further industrial development and spatial economic patterns where established core areas have a workforce mainly in secondary and tertiary sectors while peripheral areas focus on primary sector activities.

Global Economic Core States

  • Core-Periphery Model:
      - Illustrates global uneven development. For example, Britain's industrial centers relied heavily on imported raw materials from peripheral regions like India and Egypt.
      - This creates a global economic divide, where core states dominate in secondary and tertiary sectors, and peripheral states remain primarily in the primary sector.
Semi-Periphery Concept
  • Emerged as countries exhibit traits of both core and peripheral economies (e.g., Brazil, India, Mexico).
  • The semi-periphery plays a critical role in the global economy, often transitioning from peripheral status due to industrial relocation from core countries.

54-2 Factors Influencing the Location of Manufacturing

  • Common Factors: Businesses consider multiple factors when deciding on manufacturing locations to minimize production costs:
      - Energy: Essential for manufacturing efficiency. Factors like proximity to hydroelectric sources influence facility location (e.g., aluminum plants).
      - Materials: The location of factories is closely linked to the availability of raw materials. Proximity to major ports for break-of-bulk points is crucial for cost-saving during transportation.
      - Labor: Wages and workforce availability affect siting decisions. Regions with lower wage expectations often attract labor-intensive industries.
        - Contrast where highly skilled labor markets are prioritized for high-tech industries despite higher costs.
      - Markets: Location near consumer bases minimizes transportation costs, ensuring timely delivery of goods, a significant factor for manufacturers.
      - Transportation: Access to various modes of transportation (ports, railroads, roads) heavily influences manufacturing placement.
        - Innovations like cargo jets and containerization have revolutionized transport logistics, enabling factories to site closer to markets or cheaper labor.
Location Theory & Weber’s Least-Cost Theory
  • Least-Cost Theory (Alfred Weber): A foundational framework guiding manufacturing location based on transportation and labor costs.
      - Location Triangle: A conceptual model with two material sources and one market.
      - Weber posited that the position of manufacturing plants would be molded by the relative weights and costs of raw materials vs. finished products.
      - Examples include the siting of bottling plants closer to markets due to water being a widely available raw material.
  • Limitations: The model's abstraction does not always account for the complexities of real-world conditions, such as variable decision-maker knowledge and changing production cost structures over time.

Module 54 Review

  • Key Takeaways:
      - The five economic sectors each contribute distinctly to economic development.
      - The core-periphery-semi-periphery model provides insights into spatial economic relations.
      - Manufacturing location is influenced by multifaceted factors including energy, materials, labor, markets, and transportation with significant theories such as Weber's least-cost theory shaping these decisions.
