The aim of this paper is to delineate the boundary system of the local housing market areas in Seoul Metropolitan Area. Previous studies on local system of housing market areas can be classified into two groups: housing sub-market approach and housing market area(HMA). After in-depth consideration, HMA approach is selected as a method to delineate local housing market areas in Seoul Metropolitan Area for two reasons. First, housing market areas by nature can be more properly conceptualized as functional regions. Also, it is possible to accommodate housing sub-markets in the framework of HMA. Functional regionalization for delineating HMAs is implemented by using Intramax procedure (Masser and ・Brown, 1975) and 2005-2010 migration data of Seoul Metropolitan Area. According to the percentage of the intrazonal interaction, three of resulting areas, 60%, 7%0 and 75% are generated. The numbers of regions of respective result are 52, 17, and 9. All resulting areas are spatially continuos and show a certain extent of discordance with the administrative boundaries.
Key Words : Functional regionalization, Migration, Housing market area, Intramax.
