What are the characteristics of regional spatial structure patterns?

Friedman’s regional spatial structure evolution theory

Four types of regions:

1. Core area: the birthplace of new technologies and new industries

p>

Generally refers to a city or urban agglomeration area. This area has developed industry, high technological level, concentrated capital, dense population and fast economic growth. Including the following categories: ①domestic metropolitan areas; ②regional central cities; ③centers of sub-regions; ④local service centers

2. Upward transition zone: capital inflow, productivity improvement, more immigrants than immigrants

A development corridor connecting two or more core areas is generally located on the periphery of the core area and has established a certain degree of economic connection with the core area. Affected by the core area, economic development is on the rise. Increased employment opportunities can attract immigrants, and feature intensive resource utilization and sustained economic growth. There are new cities in this area, and it is possible for affiliates or secondary centers to form

3. Backward transition zone: lower productivity level, more young and middle-aged laborers emigrating

The socio-economic characteristics are A state of downward development that is stagnant or declining. This type of area may once have developed at the level of a small or medium-sized city. The reason for its downward decline may be due to the consumption of primary resources, the aging of the industrial sector, and the lack of transmission of a certain growth mechanism. The abandonment of the original industrial sector and the lack of integration with the core area The connection is not strong.

4. Resource marginal areas: areas that provide resource cooperation for the core area and promote economic development, but eventually face resource depletion and economic decline.

Generally located in remote areas, but rich in resources and conditions for development. There is the discovery and development of resources in this area; there is potential for economic development, new growth momentum may occur, and at the same time, there is the possibility of new settlements and new towns being formed here. The resource frontier area may develop into a secondary core area

Four stages in the evolution of regional spatial structure: (1) Pre-industrial stage

Regional space It is homogeneous and disorderly, with several local centers but no hierarchical structure differentiation. The level of productivity is low. The regions within the region are relatively closed. The economy is extremely underdeveloped. It is generally in a low-level equilibrium state.

(2) Transition stage

In the early stage of industrialization, the economy grew rapidly and formed a regional economic center. The space consisted of a single relatively strong economic center and backward peripheral areas. The regional spatial structure It tends to be unbalanced and form a typical binary structure.

(3) Industrialization stage

New economic centers are generated and interconnected with the original economic centers to form a regional economic center system. Several centers of varying sizes appear in the region. —Peripheral structure. It constitutes the central system of the network.

(4) Post-industrialization stage

The economy is developed, economic exchanges among various regions in the region are extensive and closely connected, economic centers of different levels and sizes develop in coordination with their peripheral regions, and the gap narrows. An integrated spatial structure system is formed.
