地下鐵 區間延長이 地價에 미치는 影響에 관한 硏究

Abstract

This research is about the land value as the consequence of expanding subway station from An-san to Dang-go-gae station in April, 1994 since after the opening of line 4 in October 1985 and line An-san in October 1988. Recently, railway is being emphasized due to the coal-yard green growth era, and it seems to be a timely research project as a new line could be contructed through the expansion of a subway line in addition to the existing lines.

Line An-san has analyzed the land value from the 1981 which is before the subway line was extended to 1986 when contruction was started, and from 1989 when the contruction was completed to 2009. Gwachoen has started from 1984 starting with the construction to 1990, and from 1995 when section opening to the very recent 2009. The metropolitan area around An-san station increased up to 45% since after the section opening in 1991~1995, and the land value of An-san city has -7.1% decreased. It was reasoned due to the future value of line Gwachoen with the accessibility improvement to Gang-nam area in Seoul after the subway line extension.

After the subway line extension, line An-san (An-san station) has increased by 68.5% with the increase of An-san city by 31% in 2001~2005 which is 2.2 times higher, and Gwacheon line (Bum-Gye station) has increased by 56.3% which is 2.5 times higher when An-yang city has increased by 22.2%. Through this fact, it is clear that the land value of metropolitan area after line extension increased by double amount compared to non-metropolitan area.

The rate of land value increased has also showed 136% of difference during 10 years depending on the distance from the subway station and utility and surrouding roads.

It is assumed here that there is a error in comparision with the average value of nation-wide and surrounding area and the sample selected for the metropolitan area as it was targeted for residence area.

It is considered that this research is suggestive subject for analyzing land value due to the subway line extension.
