ABSTRACT

The purpose of this study is a measurement of the network centrality of siㆍgunㆍgu in Korea. For this purpose, this study measured the size of centrality between 229 city, county or district areas across the country in the form of score using an origin-destination matrix based upon the commuting data of 229 cities, counties or districts of the ‘Population and Housing Census’ conducted by KOSTAT (Korea Statistics) in 2015. In this study the centrality scores of 229 city, county or district areas across the country were measured because previous studies have never conducted a centrality investigation on all 229 city, county or district areas across the country. The centralities measured in this study were degree centrality, eigen vector centrality and Bonacich beta centrality. Among these centralities, the Bonacich beta centrality is the generalization of degree centrality and eigen vector centrality. In this study the result values of degree centrality, eigen vector centrality and Bonacich beta centrality were compared, as a result it was appeared clearly that the relationship between areas was not complementary but competitive unlike previous studies. Especially, if the relationship between areas is not complementary but competitive, it was found that a result value of centrality with high objectivity is obtained by measuring with the Bonacich beta () centrality.
