For the last decades, regional and national policy in Korea has focused on economic growth, successfully realizing industrialization as a result Nevertheless, it has been continually criticized that this has formed unbalanced regional spatial structure. Population and the infrastructure of industry, education, culture, politics, etc have excessively concentrated in Seoul Metropolitan Areas (SMAs), creating negative externalities such as high cost with low efficiency in sustaining urban functions due to overcrowdings. Furthermore, regional competitiveness in non SMA regions is seriously weakened due to the skewed spatial structure. In this regard, the planning paradigm in pursuit of realizing balanced regional development has been substantially emphasized. In the process of seeking for balanced regional developments, it is critical to systematically diagnose the overall spatial structure where populations are disproportionately distributed. To this end, some quantitative indices such as Gini index, segregation index, etc. has been used to measure the inequality level of population distribution. However, it has been pointed out those indices cannot distinguish the diverse spatial patterns possibly derived by rearranging regional units over geographic space. Illustratively, spatial clustering of subregions with high population density may exacerbate the disproportionate spatial structure than when the same regional units are distributed randomly over geographic space. This, so-called "checkerboard problem" has been regarded as a fundamental methodological drawback in many inequality studies. This study aims at devising a spatial imbalance index that can explicitly account for the effect due to the spatial arrangement of unit subregions in estimating the degree of disproportionality in population distribution. The spatial index is defined as the sum of the ratio differences weighted by spatial contiguity and is decomposed into local quantities. The spatial index makes it possible both to observe the overall pattern change of unbalanced population distribution and to portray local image of disparity on a map. The index is empirically applied to examining the spatial structure of population distribution in Korea, followed by some discussions on the useful applicability as a decision support tool in the planning process of realizing balanced regional developments.
