신규 지하철 개통이 주변 아파트 가격에 미치는 영향: 지하철 서해선 노선을 사례로

Abstract

The purpose of this study is to analyze the influence of the new subway opening and the new station influence on the prices of nearby apartments, targeting subway lines in areas where transportation infrastructure is not sufficiently supplied. In this study, apartment complexes located within 500m and 1,000m radius around six subway stations that had not previously formed station influence areas were selected for research. As of June 2018, the opening date of the subway West Sea Line, the two points before and after the opening of the subway line were set as time limits, and the actual transaction price data provided by the Ministry of Land, Infrastructure and Transport were collected by time and analyzed through the double difference analysis method. According to the analysis, the opening of the subway West Sea Line has a significant impact on the prices of nearby apartments. Meanwhile, according to the analysis of the influence of station influence area by station, the price per pyeong increases as apartment complexes are included in station influence areas rather than non-stationary areas. This study can be seen as a timely study that fits the direction of the government's policy by analyzing the areas where the transportation infrastructure is insufficient, but not enough, at a time when the government puts forward the establishment of a wide-area transportation network linking the areas where the transportation infrastructure has been lacking. Based on the results of this study, we hope that policy makers can use it as a reference to come up with policies and systems for stabilizing housing prices and stabilizing housing for residents.
