Abstract
This article aims to clarify the development of the “Eupchi” which appeared as a local political typology during the Joseon Dynasty, to a modern state through its commercialization by the proliferation of the periodic market. This development is the process of urbanization of Eupchi. There were two types of Eupchis. Where transportation was not so much developed, the periodic markets were held within the Eupchi, whereas in places such as transportation hubs, periodic markets were held outside the Eupchi. This led to the decentralization of the Eupchi which before then used to have a concentric structure.
