CORE DEFINITION

The discipline that studies the spatial distribution of economic activities and its determinants. Core concepts include agglomeration economies, transport costs, economies of scale, and imperfect competition, explaining why economic activities are unevenly distributed in space, forming cores and peripheries.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Optimization of spatial layout. It provides an analytical framework for understanding industrial agglomeration, urban development, and regional disparities. In business location and market layout, it helps companies consider transport costs, market size, supply chains, and other factors to optimize geographic placement.

Anchor fast decisions

Economic activities are unevenly distributed in space because the trade-off between agglomeration economies, increasing returns to scale, and transport costs makes industries tend to concentrate. The core mechanism in new economic geography is the interplay between 'centripetal forces' (shared labor, intermediate goods, technology spillovers) and 'centrifugal forces' (congestion, land prices), forming a core-periphery structure. Falling trade costs first strengthen agglomeration, then may trigger dispersion.
