摘要

We measure regional centrality by using sociometry. The actor of sociometry is a person, whereas the actor is region in measuring regional centrality. So, the matrix of commuters among regions can be changed according to reorganize administrative district. When we measure regional centrality using the raw , administrative territory integration affect the score of regional centrality. This study listed problems with centrality measurements according to a regional integration and proposed the use of commuting traffic as a percentage of population in measuring the centrality as a way to make up for such disadvantages. To analyze its reflection effects, this study brought a case study involving the combination of Jung-gu and Jongro-gu, Gangbuk-gu and Dobong-gu. As a result, the centrality index showed an almost two-fold increase when analyzing the centrality with raw data without consideration of population size as data. In case of considering population size, on the other hand, the analysis indicated a minimized change in the centrality index. Therefore, the study working on the analysis of the centrality without considering population size needs to be reexamined. Furthermore, it will be far more desirable in the future to calculate the centrality as a percentage of population when measuring the size of centrality in a region.
