지역 간 접근성 향상과 국토 공간구조의 변화

Abstract

In general, the transport infrastructure investment improves the regional accessibility that plays a key role in promoting economic growth and restructuring the national spatial structure. Many researchers have focused only on investigating the impact of the transport infrastructure investment on economic growth. It seems that the literature has given a little attend to how the transport infrastructure investment affects the national spatial structure changes. The change of the national spatial structure appears the change of the central place hierarchy. The paper attempts to develop a model for analyzing the impact of transport infrastructure on national spatial structure based on the central place theory. The analysis is concluded using assumed data. Hence, the results obtained in the paper is suggestive rather than conclusive. This paper is organized as follows: The first step is to classify the industrial goods provided in the region. The second step is to construct a framework for analyzing changes in transport cost due to the accessibility improvement. The third step is to analyzing the impact of the transport infrastructure investment on the national spatial structure. Finally, the paper suggests policy directions for the balanced national development.
