In many core cities, the changeover from expansion to contraction has become a real challenge. Sustainable urban development is expected by consolidating living-related facilities, public facilities, housing, etc. into specific areas and improving public transportation. The city planning ability of core cities own is demanded. In order to solve urban problem, it is important to understand the population distribution within the urban area.
Therefore, this study discusses on the applicability of the spatial autocorrelation coefficient method for quantitatively understanding the distribution characteristics of the population in core cities. And understanding the situation in other similar cities can also provide hints for finding and solving problems in one’s own city. We also try to cluster the core cities.
