本研究從家戶住宅消費失衡與調整的觀點，建立一個解釋家戶在都會區內部遷移與住宅選擇的分析性模型。模型最大的特點，是將家戶對住宅的消費分成「鄰里環境服務」與「住宅單元服務」兩種，並採用個體選擇理論中之無異曲線分析法，來解釋家戶住宅消費失衡的原因（即遷移的原因）；並以住宅次市場的概念，推論處於不同失衡狀態的家戶之相對應住宅調整行為，其中最重要的假設便是家戶在鄰里環境服務與住宅單元服務消費間的抵換關係。在實證研究上，本研究利用主計處81及91年「台灣地區國內遷徙調查」之原始資料，將台北都會區分成兩個提供不同鄰里服務品質的地區環境次市場，以租屋及擁屋代表兩種不同品質的住宅單元服務，藉由遷移者在不同地區環境次市場之租擁選擇機率的比較，來驗證前述假說的正確性。以Probit模型估計的結果顯示，遷移者若由鄰里服務品質較佳之次市場遷往較差之次市場時即從台北市通往台北縣，可同時選擇較佳住宅單元服務（即擁屋）的機率較高，反之則較低，間接證實了本研究有關鄰里環境服務與住宅單元服務間存在抵換關係的假說，研究結果也提供了住宅區位與住宅權屬選擇關係之另一種角度的解釋與觀察。

We construct an analytical model for explaining the household’s intrametropolitan mobility and housing choice behavior based on the viewpoints of housing consumption disequilibrium and adjustment. In our models, the households’ consumption for housing is divided into two dimensions as neighborhood services and housing unit services, and the indifference map is utilized to analyze the reasons for moving. Two housing sub-markets are defined and incorporated into the indifference map to explain the household’s corresponding adjustment for housing consumption, in which the trade-off relationship is hypothesized to exist between neighborhood services and dwelling unit services. The movers within Taipei Metropolitan Area are selected from the data set, “Internal Migration Survey in Taiwan Area”, for testing the hypothesis. Taipei Metropolitan Area is divided into two neighborhood sub-markets according to their quality, and two types of housing tenure are used to representing the dwelling unit services of different quality. By comparing the movers’ home ownership probabilities (estimated by using Probit model) in different neighborhood sub-markets, the hypothesis can thus be tested. The empirical results indicate that those who moved from a better neighborhood sub-market to a worse one, might have higher probability to consume more housing unit services, which supports the hypothesis to some extent.
