Option 2 : Friendman

Core-periphery model of economic development:

  • This model was developed in 1963 by John Friedmann.
  • It is a model of the spatial organization of human activity based upon the equal distribution of power in the economy and society.
  • The core dominates (although it may, in turn, be dominated from outside) whilst the periphery is dependent.
  • This dependence is structured through the relation of exchange between core and periphery.

Core-periphery stages:

Stage Characteristics
Stage 1 (Pre-industrial)
  • The pre-industrial (agricultural) society, with localized economies and a small-scale settlement structure.
  • Each settlement is fairly isolated, activities are dispersed and mobility is low.
  • There are limited differences between spatial entities in terms of levels of economic development
Stage 2 (Transitional)
  • The concentration of the economy in the core city begins as a result of innovation. capital accumulation and industrial growth.
  • The specific reasons behind this concentration are often not too clear, location (better access) being a significant factor, but the fact remains that a dominant centre emerges within an urban system to become its growth pole.
  • Trade and mobility increase, but within a pattern dominated by the core even if the overall mobility remained low.
  • Among the numerous examples of such a phase are the early industrialization of Great Britain in the late 18th century or the beginning of the colonial incorporation of Latin America, Africa, or Asia
Stage 3 (Industrial)
  • Through a process of economic growth and diffusion, other growth centres emerge.
  • The main reasons for deconcentration are increasing input costs (mainly labor and land) in the core area.
  • This diffusion is linked with increased interactions between elements of the urban system and the construction of transport infrastructures.
Stage 4 (Post-industrial)
  • The urban system becomes fully integrated and spatial inequalities are reduced significantly.
  • The distribution of economic activities creates a specialization and a division of labor linked with intense flows along high-capacity transport corridors.
  • The factors that have favoured spatial inequalities in the previous phases of development have structured dominant poles of the urban system and favoured the setting of a large commercial gateway, usually a world city.
