Manufacturing and Economic Geography
Introduction to Manufacturing and the Concept of Value Added
Definition of Manufacturing: The fundamental process of transforming raw materials into a finished good.
The Concept of Value Added: Every step of production increases the worth of the material. Examples include:
Wheat $\rightarrow$ flour $\rightarrow$ bread.
Copper $\rightarrow$ circuits $\rightarrow$ cell phone.
Theoretical Caveat: There is a debate regarding whether the basic raw material always holds the lowest value. For example, an uncut tree or an uncaught lobster possesses significant inherent value before any manufacturing occurs.
Modernization and Industrialization: Manufacturing is intrinsically linked to modernizing a society. It requires specific infrastructure and social changes:
Energy Requirements: Factories require reliable electricity and power sources.
Assembly Lines: These require human capital, specifically workers and skilled managers.
Urbanization: Industrialization necessitates cities to provide housing, sewers, and consumer stores for workers.
Market Connectivity: Products require transport links (roads, rail, ports) to reach consumers.
Development Transition: Move from a "developing" to a "developed" status is often defined by the process of industrializing.
Factors Influencing the Location of Manufacturing
Input Requirements:
Access to reliable energy sources.
Proximity to raw materials.
Weight Dynamics: Selection depends on whether the manufacturing process is weight-gaining (product is heavier/bulkier than materials) or weight-reducing (materials are heavier than the final product).
Labor Considerations:
Demand for high-skill versus low-skill labor.
Wage levels and labor availability.
Transportation Infrastructure:
Availability of roads, ports, and rail systems.
Rate Structures: Costs are based on the distance traveled. Transport by water (ship) is significantly cheaper and makes distance far less important.
Governmental Factors:
Tax structures and environmental or safety regulations.
Financial incentives provided to companies.
Availability of infrastructure like healthcare for employees.
Additional Geographical Factors:
Local weather patterns and the cost of land.
Proximity to specialized suppliers.
Market orientation: Whether the target market is local or global.
Operational Tradeoffs:
Proximity to City/Markets: Leads to lower transport costs but higher labor costs.
Proximity to Raw Materials: Leads to lower labor costs but higher transportation costs for the finished goods.
Manufacturing and Urbanization Trends
The Rise of Cities: Manufacturing was the primary driver for urbanization, moving populations from farms to urban centers.
Geographic Winners: Initially, cities located on water thrived, followed by those on rail lines.
The Role of Highways and Suburbanization: The development of highway systems helped cities decline as manufacturing moved to suburbs. This shifted from "intensive" manufacturing (compact, urban) to "extensive" manufacturing (sprawling, suburban).
The Decline of the 1970s and 1980s: Many cities unraveled during this period, characterized by "white flight" and industrial decay.
The Service-Led Rebound: Cities eventually rebounded not because of manufacturing, but through the growth of the service sector.
Future Prospects: There is a question regarding whether manufacturing has a future in cities, potentially through "Advanced Manufacturing" (e.g., the Brooklyn Navy Yard).
Historical and Geographical Evolution of Manufacturing
Early Industrialization: Primary hubs included the US, Europe, and the Soviet Union, utilizing their initial advantage in roads, ports, workers, and energy.
The 1950s Shift: Japan began its industrialization.
The Rise of the Asian Tigers: Newly Industrialized Economies (NIEs) followed Japan's model.
Post-Cold War (1990s): The Eastern Bloc entered the global manufacturing landscape.
The Three Industrial Revolutions:
1st Revolution: Focused on Mechanization.
2nd Revolution: Focused on Mass Production.
3rd Revolution (): Characterized by the internet, computers, and automation.
The Current Global Landscape: Manufacturing is now fully globalized, as seen in the integrated supply chains of the automotive industry.
Internationalization and Trade Agreements
Modernization Goals: Historically, trade is sought to facilitate modernization via manufacturing.
Regional Impacts and Agreements:
NAFTA: Facilitated the move of manufacturing from the US to Mexico via Maquiladoras.
European Union (EU): Facilitated movement from West to East Europe.
WTO: Oversaw movement from the Global North to the Global South.
Chinese Economic Strategy: Utilized Special Economic Zones (SEZ) and Export Processing Zones (EPZ) to surge trade.
Intermediate Goods: There has been a notable rise in the trade of intermediate goods (components used to make a final product) rather than just finished products.
US Employment Shifts: 1940 to 2016
Industry with Largest Employment by Decade:
1940: Manufacturing; Agriculture and mining.
1950: Manufacturing; Wholesale and retail trade.
1960: Manufacturing; Wholesale and retail trade.
1970: Manufacturing; Public administration.
1980: Manufacturing; Services (administrative, leisure, food).
1990: Manufacturing; Wholesale and retail trade.
2000: Services (administrative, leisure, food); Wholesale and retail trade.
2010: Services; Wholesale and retail trade.
2016: Services; Health services.
Deindustrialization in the West
Permanent Geographic Decline: Impacted regions include the US Rustbelt, the North of the UK, and the Ruhr in Germany.
Reverse Multipliers: Deindustrialization hurts locally owned retail, making areas ripe for big-box retailers like Wal-Mart or Dollar stores. These often become the only job prospects for former factory workers.
Social Infrastructure Collapse: When plants close, schools, hospitals, movie theaters, and car dealerships often follow.
Labor Organizations: There has been a major decrease in union membership.
Economic Impact: Wages have fallen significantly. It remains a debated question if certain items, like underwear, should still be manufactured within the US.
Quantitative Data on the US Manufacturing Decline
Manufacturing Share of Employment: Has dropped from nearly of non-farm employment in 1950 to roughly by 2020.
Production Indices (since 2000):
High-tech industries have seen significant growth (measured on a log scale).
Decidedly downward trends are seen in durable and nondurable goods like clothes, shoes, and textiles.

Industrial Policy and the Future of Manufacturing
Definition of Industrial Policy: Steering public resources to lubricate an innovative economic ecosystem to provide long-term societal benefits.
Strategic Targeting: Focuses on innovation, tech development, education/skills support, research, finance, and trade opportunities.
US Historical Context (Informal Policy): The US has traditionally avoided "government in business" but has used industrial policy for major projects like the Manhattan Project, Moon Mission, Silicon Valley development, DARPA, and the Human Genome project.
Contemporary Examples: Operation Warp Speed (COVID-19).
International Models:
Japan: Autos.
Korea: Chaebols.
Taiwan: Electronics.
China: SEZ / EPZ structures.
Resurgent Industries: Semiconductors, Green Tech, Space, Internet of Things (IoT), 3D Printing, and Therapeutics.
Current Drawbacks and Vulnerabilities: The current system is sensitive to shocks, lacks supplier oversight, creates environmental externalities, and poses national security risks.
The Concept of "Shoring": Includes On-shoring, Re-shoring, Near-shoring, and Friend-shoring to mitigate risks.
Technological Shift: The real benefit in new manufacturing is in design and software (AI, robotics, 3D printing). This allows for a lighter environmental footprint and "decoupling" from traditional, resource-heavy processes.
