捷運系統在國內屬於新的都市運輸工具,過去幾年探討捷運系統的影響研究,絕大部分是在捷運系統實際營運之前進行有與無的分析推論,尚未進行完整的營運前後調查與比較分析。本研究以台北捷運紅線沿線房地交易實例為樣本,利用多元迴歸模型,探討捷運營運前與後沿線房地屬性特徵價格之變化;繼而利用F檢定,分析不同區位條件迴歸模型間是否存在顯著差異;最後並比較傳統迴歸與模糊迴歸兩種模型間的差異。研究結果發現:面積、屋齡、距公共設施距離三項屬性之特徵價格,在捷運營運前後產生顯著之變化;前述變化會因房地是否鄰接地面型式捷運、是否鄰接地下型式捷運、是否位淤市區、是否位於市區邊綠、是否為獨戶住宅、是否為大廈、是否為捷運站區、是否為非捷運站區、是否為商業區以及是否為住宅區子條件而有顯著差異;Tanaka模糊迴歸與傳統迴歸兩種模型在房地價格的研究中各自具有其優缺點,但仍以傳統迴歸方法較具說服力,其他模糊迴歸分析方法的適用性,則尚待進一步驗證。
Since the MRT is a new type of infrastructure in Taiwan, most of the impact studies proceeded without comparisons of situations before the MRT's opening. The complete before-and-after comparisons still await investigation. This study analzyed the property hedonic price before and after Taipei MRT's opening. The samples were investigated along the MRT red line for two periods: 1993-1995 AC. (before the MRT's opening) and 1997-1999 AC. (after MRT's opening). Multiple regression, Chow test, and fuzzy regression were used to analyze these samples. According to the empirical analysis, we arrived at the following conclusions: First, the hedonic price of floor area, building age, and distance to public facility are all significantly influenced by the MRT's opening. Second, the effects of the MRT's opening on hedonic price vary significantly because of the surface type of MRT the underground type of MRI, the CBD area, the fringe of CBD, the single unit house, the mansion, the location close to MRT station, the commercial area, and the residential area. Third, both of the traditional regression and Tanaka fuzzy regression are useful, but in general, the former is more persuasive than the latter on analyzing hedonic price. The abilities of other fuzzy regression methods still await exploration.
