Core-Periphery
The relationship between the Core & Periphery mirrors that of MEDCs and LEDCs.
MEDCs have a greater concentration of industry and development through a mixture of positive
factors and the multiplier effect. As a result this area is the core.
Less developed areas (LECDs) are peripheral areas due to their lack of development and
dependence on the core regions.
As can be seen in the
map, developed nations
such as the UK,USA and
Australia are known as
Core. Whereas LEDCs
such as Kenya, Lesotho
and Madagascar are
Peripheral areas.…read more

Core & Periphery Model
The Core & Periphery Model is the simple idea that core cities, regions and countries will
develop leaving a peripheral area outside. These core areas will develop because of physical
and/or human advantages.
It is the also stated that the developed core regions will exploit the periphery through
migration or resource use.
The Core area will be an area with
·A coastline
·Good Transport Links
· Good Education
The Periphery will often have:
·No resources
·Conflict/Corruption
·Debt…read more

Freidmann's Theory
The four stages of development are;
1. Independently developing towns have little contact between
them
2. One town or region will become dominant
3. Semi-Periphery areas begin to develop increasing the flow
between core and periphery.
4. All areas are developed and dependent on each other.
Friedmann argued that beneficial effects will spread from the
core to the Periphery…read more

Myrdal's Model of Cumulative
Causation
Myrdal's model is used to explain regional differences that caused inequalities.
·Successful growth of an area can cause backwash or polarisation. The core has a cumulative
advantage over the Periphery.
·Areas will have both upward and downward spirals due to the multiplier effect.
·Growth will spread to the periphery (slowly) as the core needs resources.
·Land prices in the core will rise resulting in the movement of businesses to the Periphery.
·The development gap is dependent on the rate of backwash and spread;
·If backwash is stronger the gap increases
·If spread dominates the gap is decreasing…read more
