台北都會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逐漸形成。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，但從投資需求、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差異，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屬性是否有差異，藉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，會優先將預算花在與自住相關的住宅服務上，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。

The high ownership rate is the feature in Taiwan. For the increasing GDP, investment motive and quality needs, the sub-market of second homes will be popular in Taiwan. There are some discussion of the second homes issue in the U.S., but no reference in Taiwan yet. Therefore, we would like to discuss the features about second homes in Taiwan in order to know the behavior of second homes and the features of the second homes sub-market. We use the second homes from the housing stock database of government. We analyze the influence of housing choice by compare the difference of one's first home and second home so that find the features of behavior of second home consumption. We found that the owner will buy more quality house than previous home for the consumption use, and they also have the 'emotion' and 'location' preference so that to choice the house near and the same building type than previous home. This is the first time that we got the evidence about the buyer's behavior of second home. Furthermore, the buyers' that face the output of housing services about Self-Occupancy and Non-Self-Occupancy would pay housing services about living first, and have shorter interval time which purchase both houses.
