摘要

The objective this study is to explain the effect of dynamic externalities and spatial structure on urban growth through small-scale unit analysis. Empirical models measure the degree of specialisation, diversity, and competition and the effect in Seoul Metropolitan Area (SMA). Positive and negative agglomeration effects occur simultaneously in sub-centers depending on the industrial type. Decentralisation occurs because of the manufacturing industry, whereas the service industry remains influential at the urban center. Dynamic externalities at sub-center in SMA show similar patterns in most industries. Lower growth in highly specialised industries and high growth in more diversified industries.
