How did the capitalist world system change relationships among cities in different parts of the world?

The capitalist world system, emerging in the 15th century, fundamentally restructured relationships between cities by creating an unequal, interdependent network between the industrial "core" and the underdeveloped "periphery".1

Core-Periphery Dynamics

This system harnessed the labor and productivity of distant regions to serve the European core, establishing a pattern of unequal exchange where industrial commodities were traded for raw materials. Over time, this evolved into a global urban culture where cities perform distinct, interactive roles.1

The Shift to Mass-Communications Cities

In the modern era, the role of cities in the core has shifted from industrial manufacturing to managerial control. Metropoles like London, New York, and Tokyo now function as command-and-coordination posts for transnational corporations, utilizing high-technology mass communication to manage global production.23

Consequences for Urban Relationships

• Deindustrialization: As manufacturing is exported to the periphery or lower-cost regions, older industrial cities in the core have declined.32
• Global Networks: Global cities are increasingly interconnected with one another across a transnational field, often becoming "de-linked" from their own national economies.3
• Labor Segmentation: The system creates precarious labor conditions in both core and peripheral cities, where underprivileged populations often rely on mutual-aid networks to survive in the face of economic insecurity.2
