ABSTRACT

The concept of the city-region has attracted in recent years. It has been recognized as a dynamic center of economic innovation as well as the spatial unit that compares the regional competitiveness on a global scale. The purposes of this study are to delimitate the city-region system in Korea, applying the method of TTWA(travel-to-work area) and to analyze spatial structure of city-regions. The adequate thresholds of self-containment rate(demand and supply side) and number of resident workers were set, based on the result of sensitivity analysis. Korea was delimitated into 39 TTWAs, including 7 TTWAs which are consist of single shi or gun. If 7 TTWAS are re-delineated using the boundary of the regional happy living areas, city-regions in Korea can be set into 32. In this study, the spatial structure of city-regions was analyzed in terms of morphological polycentricity as well as functional polycentricity. The functional polycentricity is related to the size of the city-region and morphological polycentricity. The results of this study give some implications for implementing the regional development policy towards the city–region as the spatial unit. Further, this study may guide the in-depth research concerning the effect of polycentric city-region on the regional competitiveness and sustainable development.
