The necessity for the interregional differentiation of national assistance arises from the general perception that existing regional policies are ineffective to accomplish the balanced regional development. Existing regional policies and implementation system have limited capabilities to contribute substantially to the balanced territorial development. There is a growing need to enhance balanced interregional development through the redistribution of national resources by differentiating government assistance depending on the development level.
The study attempts to categorize regions using statistical data on various aspects of regional development. Fifteen social and economic indices were employed to classify all of the 232 local autonomous regions throughout the country. A cluster analysis using the SPSS identified four groups of regions according to the level of development. The first and most advanced group includes 53 regions; The second and third group include 71 and 60 regions respectively; The last and most depressed group includes 48 regions. The study suggests the spatial policy framework that reflects differential characteristics according to this grouping of regions.
