Some of the classification region

Territorial division based on the center-periphery region (centreperiphery), although the basic classification, but can be very rough as a useful policy framework for regional development. Bernard Okun and Richard W. Ridrardson create a classification based on the level prosperity and growing capabilities of each region. The level of prosperity expressed by regional income per capita, and the ability to grow is reflected by the growth rate of development. Furthermore, based on these criteria, the various regions can be classified into 4 groups, as follows:

1. The areas of low-income per capita and less developed or low per capita and stagnant regions (LS).

2. The areas of income per capita is high but less developed or high per capita income and stagnant regions (HS).

3. The areas of income per capita is low but growing or low per capita income and growing regions (LG).

4. The areas of high per capita income and growing or high per capita in come, and growing regions (HG).

The classification above can be used to determine the extent of the influence of internal mobility of population resources, capital and other production factors, as well as trade flows between regions, whether to provide benefits or otherwise will create obstacles in the growth areas, both in the region of origin and in destination region. As an example can be mentioned, namely the short-term migration of population out of the area are low-income per capita to developing regions will tend to affect the level of incompatibility between the two regions,

and its influence in the long term will provide the benefits of good growth in the region of origin and in destination areas.

Another example, that migration flows into the region per capita income high and growing per capita than low-income areas and less developed in general consists of low-quality labor force, this will reduce the level of income per capita in the destination, in other hand reduces the labor supply in the region of origin, which in turn tend to be increasing income per capita in the region.

J. Friedmann and W. Aloson showing classification consisting of four development areas, namely (i) metropolitan regions, (1I) deoelopmenat xes, (iii) the frontier regions, d an (iv) depressed regions. Metropolitan regions or metropolitan areas are often referred to as a core regions (core areas). These development centers are usually the big cities with all the activities and facilities industry, trade, transport and communications, finance and banking, and government administration, all of which have major influence on the development of surrounding areas (hinterland) and other small towns (small centers).

Development axes or axis of development, covering areas located on the transportation network that connects two or more metropolitan areas. Roughly speaking we can say that the prospects of development these areas will more or less proportional to the level and extent of development of the territories they relate. As an example can be noted that the axis of development in Japan focuses on three major areas namely the Tokyo-Yokohama, Nagoya, Kyoto, and Osaka-Kobe.

Frontier regions or border areas. With the advancement of new technology, population pressure, as well as new national goals often point to encourage development in areas that have not been processed (oirgin areas).

Depressed regions or areas of stagnation or decline in development because it has no potential for development of reliable resources, such as arid and arid regions. Other zoning system in some countries could be offered, for example in the Netherlands (Regional Economic Policy 1977-1980) classification consists of (i) centers

lgrowth scattered growth centers), (ii) the region that has a drive for development (incentiae area) located in the Northeast, (iii) the restructured region (restructuring area) who are at the tengatr, and (iv) areas that have been restricted (restriction area \ that is the province located in the South.

In France in the homogeneous region are met: (i) areas that are very advanced (the most highly developed regions) consisting of the city of Paris and the surrounding areas, the areas north and east, (ii) the newly developed area (The

newly developing zones) such as regions of Lyon and Provence, and (iii) areas that are underdeveloped and slow growth (less developed and Slowly growing regions) which includes the French territories of the West, Southwest and Central .. In Canada there Hartland terms of concentration of industrial activities and their supporters are more advanced than the hinterland (the back)

Develop the concept of Spatial Economic region

In the discussion of regional problems are the use of various terms. There are some authors (of whom Boudeville) use spatial terms, although between the region and there are spatial but not substantial difference. Regarding the spatial understanding itself turned out not merge because a different view considering that the studies that are multi-discipline area (of Earth Sciences, Economics, Social Sciences, Mathematical Sciences and others). so the spatial structure have many different terms.

Spatial structure can be interpreted as a traditional environment of human life, have provisions and its own ability to regulate the activities of its inhabitants, and even the spatial structure is considered as one of the goals of development. logically and historically, according Boudeville spatial structure can be divided into three terms, namely spatial economics, spatial geographic region, and spatial mathematics. The concept of spatial economics has a more operational sense, for example associated with capital investment, transport networks, industrial, and agricultural technologies create new developments, which include the materials of new materials and new rules. The concept of economic spatial layout can be distinguished by geographic region

Earth Sciences experts put humans in the natural environment, contrary economists regard the environment as one of the factors that influence human activities. Spatial geographic area is a three-dimensional spatial structure, while the economic spatial structure is more complex and multi-dimensional nature.

Spatial economy with different spatial mathematics, namely mathematical spatial truly is abstract and has nothing to do with geographic location. if a spatial structure is formed solely by economic variables, the spatial structure is the spatial structure of mathematics, which means that mathematically can happen everywhere, but otherwise the economic spatial structure is the application of economic variables in above for human needs on a geographic spatial, and through a mathematical transformation can be explained the economic process.

In terms of formal relationship development, spatial economics is a field or arena of power (a field of forces), is a spatial polarization, namely as a place where there is a concentration or concentration of economic activities which are relatively large (the factories and corporations) and significantly different than the surrounding areas. In the field of industrial activity can be shown that the greater the gap in terms of productivity levels in urban and in rural areas, which raised the problem of spatial inequality.

In the abstract, spatial economics emphasizes the aspects of convergence process of growth at the spatial points (Perroux). Within the framework of the analysis area, geographic dimension has been put into effect the development center, this means that the spatial economy is very closely related

with a spatial geographic region (Boudeille). According to Friedmann, Development comes at a small number of centers that change lies in the interaction point which has the highest potential; development tends to spread down and out from these centers into the surrounding area who have lower interaction potential, but does not address the problem of optimum site selection industry and does not specify what type of investment also should be established in urban centers, therefore classified as Friedmann theory without spatial structure (spacelesss) as well as the theory of Perroux although the scope of broader review.
