台北都匯區第二屋購屋行為之研究-從第一屋與第二屋特徵差異分析The Buyer's Behavior of the Second Homes in Taipei--An Analysis of Attributes of the first home to second home

高住宅自有率一直是台灣地區住宅市場的一大特色,隨著所得增加、投資規劃及對生活品質的要求的提昇,購買第二屋住宅的趨勢將邊漸形成。國外多半以投資或休閒的角度來探討此一議題,國內則尚無文獻討論,但從投管需求、換屋需求甚至是近來逐漸受到重視的休閒需求來看,我們對這些行為的了解相當不足。因此探討第二屋購屋行為的各項特質,有助了解住宅第二屋消費行為及未來可能形成的住宅次市場的特性。
本文從所有權人戶籍與房屋地址的異同,並配合第一屋與第二屋房價的羞異,來判斷購屋者是換屋自住或非換屋自住目的,以進一步分析購屋者的第二屋屬性與第一屋為性是否有差異,籍此分析不同購屋目的所具有的第二屋購屋行為模式。
我們從地政事務所的建物登記資料庫中,針對台北縣、市住宅存量中個人持有二屋住宅的樣本進行分析,發現相較於非換屋自住目的購屋者,換屋自住目的的購屋者會選擇品質較第一屋高的住宅,如面積較大、屋齡較新的房屋:且換屋自住者在購屋行為上存有情感習慣或地域性的偏好,較容易購買與原居住房屋相同類型及相同區位的房屋:此外,購屋者在面臨自住與非自住的住宅服務支出時,優先將預算花在與自住相的住宅服務上,使得換屋自住的第二屋購屋間隔時間較非換屋自住者為短。
關鍵詞:第二屋、購屋行為、換屋自住·非換屋自住
