本稿は平成27年度に京都大学大学院人間・環境学研究科に提出した修士論文の内容を一部修正したものである。 At first, compares some social-economic regional divisions of Ukraine and by analyzing this, it is obvious that in six regions exists strong commonality. In the next unit, determining oblast as a unit, the author does regional division by each items, in other words by physical, demographical, natural-resource, industrial, and linguistic, using thematic maps in the atlas or statistics. Six cities are determined as a core city, in which lives more than 500 thousand people. Then overlays five color maps, what have same transparency, and finds commonality of oblasts by similarity of color. As a result, Ukraine is divided by six regions: Western, Central, Southern, South-eastern, North-eastern, and Eastern regions. Western region is composed by three subregions. Next the author writes about every divided region, and mentions about relationship with big regions or Ukraine. Finally, it is obvious that in Ukraine exist some various regions, not only two regions, and in this area exists the comparison of strong common periphery and not-integrated center. Future issues are analyzing place names of big regions in Ukraine, and comprehending formulation process of Ukrainian regions.
