本文是在「住宅」（ housing ）的理論下，探討住宅之特質。主要的目的，是經 由住宅特性討論過程，更加清楚地掌握住宅的問題，及其相對應之策略，藉以釐清部分支離 ， 或片斷不整的理論及觀念，進而建立一兼具「解釋性」（ explanation ）與「預測性」 （ prediction ）的分析性模式。 「住宅」在本質上具有「住戶」（ household ）與「住 屋」（ dwelling unit ）的相對屬性。 但是，這相對屬性的相關測度、甚至相對屬性與住 戶的居住行為決策（如住屋選擇、人口遷移）的分析，尚付闕如。本文將透過「典型相關」 分析（ canonical correlation analysis ），檢定典型相關係數的顯著性，驗證相對屬性 具有相互影響的關係，並且進一步以相對性為依據，提出相對應之策略。 住宅問題的分析與政策的擬定，僅從單一方面的「住戶」或「住屋」提出因應策略，實無法 真正解決問題。本文認為在觀念上，「住宅」不應只是「住屋」本身、更包含了「人」的因 素及「家庭」關係，面對臺灣地區如此嚴重而複雜的住宅問題，更應兼顧此三者，尋求解決 之道。

　　　　　What this paper wishes to investigate is the measurement of characteristic, duality terminologically, on housing. And the purpose of this paper is to raise the concept of duality and establish an analytical model containing two components of explanation as well as prediction. Housing, essentially, is composed of dual attributes, household and dwelling unit. While the absence of measurement and the relative decisions, due to the difficulty of conceptualization, is to perplex the study on housing. Canonical correlation analysis, methodologically, is used in this paper to verify the significance of duality on housing and, in addition, to raise the strategy politically. Analysis on the issue and policy on housing will not work effectively with strategy either on "household" or "dwelling umit." Conceptually, housing is the building- block of "household," "dwelling umit," and "family" in this paper. The considerable question of housing in Taiwan, therefore, must be dis-aggregated with "dwelling umit," "household," and "family.".
