捷運系統對鄰近住宅價格之影響-以台中捷運綠線為例

本研究主要探討台中捷運綠線於試運後，對於鄰近住宅價格的影響，且位於捷運站影響範圍內之住宅與位於捷運站影響範圍外之住宅價格之變化，並先使用特徵價格理論 (Hedonic Price Theory) 及差異中之差異法(Difference-in-Difference method) 進行住宅屬性分析。住宅樣本採用期間2017年5月1日~ 2020年4月30日，資料取自內政部不動產交易實價查詢服務網並透過理資訊圖資雲服務平台進行門牌轉換取得座標測量住宅與捷運站之距離，實證結果顯示，住宅坪數、屋齡平方、房間數、客廳數、衛浴數、位於一樓、土地使用分類為商業區、類型為住宅大樓、附有車位之特徵，對住宅價格呈現顯著正向影響；屋齡、位於四樓之特徵，則對住宅價格呈現顯著負向影響。而台中捷運綠線試運後並位於捷運站800公尺內之住宅，住宅價格呈現負向影響但效果不顯著，而台中捷運綠線試運後並位於捷運站300~800公尺內之住宅，住宅價格則呈現顯著負向影響，本研究推論民眾預期性心理使住宅價格上漲情形早於試運前發生，試運後帶給位於影響範圍內之住宅的負面影響，如：噪音、擁擠等，大於其所帶來之正面影響，而導致差異中之差異法中交乘項呈現負數。

This study mainly discussed whether the impact of the Taichung Metropolitan Rapid Transit (TMRT) Green Line trial operation has an impact on the price of neighboring housing and the change in housing prices for houses located inside and outside a certain range of influence of the MRT station. Hedonic Price Theory and Difference-in-Difference method were used to analyze residential properties. The real estate price registration data for Taichung from May 1, 2017 to April 30, 2020 was collected that based on the real estate transaction real-price inquiry service website of the Ministry of the Interior and the Taiwan Geospatial One Stop (TGOS). Empirical results showed the characteristics including building area, building age squared, number of rooms, number of living rooms, number of bathrooms, whether the house was located on the first floor or not, the commercial area of land classification, the type of housing, and whether the house has parking spaces or not, all had a significant positive effect on housing prices. Building age and located on the fourth floor had a significant negative effect on housing prices. The housing price had a negative effect but no significant within 800 meters of the MRT station after the trial operation of the TMRT Green Line. Within 300~800 meters of the MRT station had a significant negative effect on housing prices. This research inferred that anticipatory psychology had caused the housing price rise earlier than the trial operation. The effect of negative factors such as noise, crowding were greater than the positive effect, so that the multiplication term in the difference-in-difference method is negative.
