房價可反應家戶負擔能力，在家戶遷移決策上扮演重要角色，鑒於國內遷移相關研究多欠缺房價的考慮，本研究採用2009年「住宅需求動向調查」之已購屋者的資料，以二元羅吉特迴歸模型進行實證，分析臺北縣（市）家戶的遷移決策，了解原居住在臺北市（縣）之家戶選擇在臺北市（縣）內遷移或選擇向臺北縣（市）遷移的影響因素。住宅之單價及屋齡對臺北都會區的家戶均為影響遷移決策的關鍵因素。首購之家戶傾向遷往臺北縣，首次購屋者較非首購家戶會考慮住宅的負擔能力得到證實。教育程度及家戶年所得愈高，傾向遷往臺北市，另購屋決策者搜尋時間增加傾向遷往臺北市，顯示臺北市的住宅市場環境不確定性較臺北縣住宅市場高，亦可能是因為家戶進行遷移決策時帶著先前的參考價格偏誤進入市場，從高評價往低評價地區遷移，會減少搜尋行為而有較快的決策速度。本研究有助於了解臺北都會區之間人口流動的情形，作為政府住宅政策的參考依據。 / House price, which is an indicate to household's ability, plays an important role in the mobility decision. However, few research in Taiwan has touched this issue. Therefore, we use the home buyers' data in the greater Taipei area from 2009's "Housing Demand Survey" to convey our empirical study by employing a binary logistic regression model. Empirically, we find that the price and age of house are the key determinants of the household mobility in the greater Taipei area. First-time home buyers tend to move to the Taipei County. Our research confirms that the first-time home buyers consider the price much more than those who have previously acquired a house (or more) of their own. The households with a higher education level or greater pay tend to move to the Taipei City. Thoroughly-researched home buyers prefer to move to Taipei City. This indicates that the uncertainty of the Taipei City’s house market is greater than of the Taipei County. Or this is due to the fact that households tend to enter the market with biased previous prices, when households from higher evaluation location move to lower, they make mobility decision faster. The results are meaningful for the supply of housing market and public facility services.
