ABSTRACT

This paper aims to delimitate the metropolitan regions (MRs) based on interregional functional linkages and to investigate temporal change of urban sprawl in those regions. The five MRs (Seoul MR, Busan MR, Daegu MR, Gwangju MR, and Daejeon MR) delimitated have the sprawl index of population and employment calculated, respectively. The result shows that both population and employment have sprawled out in all the MRs since 2000. Population sprawl is more active than employment sprawl, and population size of each MR tends to have an inverse relationship with sprawl level. Especially population sprawl is proceeded with relatively rapid speed in Seoul MR. Future research needs to measure urban sprawl based on multidimensional aspects in the subregions of MRs.
