This study conducted time-series analysis of self-sufficiency to evaluate the growth pattern of the Seoul Metropolitan Area (SMA). This study focuses on 65 elementary local authorities in SMA excluding Ongjin. The temporal scope of this study is from 1995, when the construction of first New Town was completed, to 2000, 2005 and 2010. Considering the limitation of precedent studies, this study evaluated self-sufficiency of target areas in the variety of hierarchical levels. Assuming that the significance of each indicator varies, the weight of each indicator was determined by AHP based on surveying some professionals. Consequently, self-sufficiency of economic aspect was identified as the most significant element. Assuming that there is interrelationship between regions, spatial auto-correlation analysis was completed. Moran’s I was used for global analysis, and Local Moran’s I for local pattern analysis. The analysis result confirmed what the distribution pattern of Metropolitan self-sufficiency had positive spatial autocorrelation. The central area of Seoul showed strong clustering pattern whilst Incheon had weaker one. Also, it is found that the number of clusters has been decreasing with the passage of time. It was evaluated that self-sufficiency and centrality of SMA were dispersed and equalised from Seoul to the adjacent regions
