Which of the following is an example of an agglomeration effect in industrial geography?

• A. Firms clustering in a metropolitan area to share infrastructure and skilled labor.
• B. Firms dispersing across rural areas to avoid congestion.
• C. A firm relocating to a distant country to reduce competition.
• D. Firms moving to isolated locations to avoid knowledge spillovers.

Answer: (C)

Agglomeration effects occur when firms gain advantages from being close to other firms and related institutions in a city or region. In a metropolitan area, clustering allows firms to share infrastructure and services, tap into a large pool of skilled labor, and access nearby suppliers and specialized support networks. Proximity also facilitates knowledge spillovers—informal exchanges of ideas, practices, and innovations between neighboring firms, universities, and research centers—which can boost productivity and innovation for all the clustered businesses. That combination of cost savings, easier access to talent, and faster knowledge transfer is the hallmark of agglomeration economies.

The other scenarios describe dispersion or relocation strategies that reduce or bypass these proximity-based benefits. Spreading firms into rural areas lowers the density of suppliers and labor pools and increases transport costs. Moving production overseas shifts focus from local clustering to international considerations and market access, not the local knowledge-sharing advantages. Locating in isolation to avoid spillovers runs directly against the idea of benefits gained from proximity.
