國內對於住宅需求的相關研究，多偏向住宅價格、合理房價與購買力、消費量等研究，但是對於消費者住宅選擇行為的研究則較少見。住宅需求的主體以個體的家戶為單位，家戶在所得的限制之下，追求效用的最大化，做出遷移決策、區位選擇、增建決策等。 觀察台灣的都市現象，台北市的房價所得比高達8倍以上，不但居全台灣之冠，更遠超過歐美國家的水準，國內高房價的壓力會影響家戶的遷移成本與區位選擇。另外，在台北市的住宅類型八成以上為公寓大廈，只能從陽台或屋頂平台小幅增建，增加的住宅面積有限，未申請建照的增建多屬不合法的違建行為，無法自由調整，因此家戶採取增建方式調整住宅需求的行為會受到限制。而國內住、商、工混雜，土地相容使用，就業區位可能與住宅區位相距不遠，因此通勤成本可能較低，這些與國外迥異的都市背景，使得本研究想解構在台灣家戶的住宅調整決策與區位選擇行為。 本研究將家戶的生命週期類型與住宅遷移、區位選擇、增建決策相連結，探討每個特殊的生命週期家戶，其住宅調整決策的差異，分析各生命週期家戶的區隔，其結果有助於了解住宅次市場區隔以及住宅下濾、換屋行為。進一步探討家戶的住宅區位選擇: 台北市女性就業，使家庭所得、通勤成本增加，其住宅區位選擇與通勤行為應與單薪家戶不同，並驗證是否受到房價與通勤成本的取捨、相關資源與夫妻決策權力、以及家庭責任義務的影響。最後，探討戶長及配偶對於區位選擇的影響，驗證戶長配偶模式是否比過去研究以戶長屬性代替家戶屬性的模式較佳，分析家戶屬性所引申的住宅需求如何影響家戶的住宅區位選擇，以及分析夫妻的資源與決策影響力的性別差異關係。女性身為戶長，其決策影響力的消長應與一般傳統家戶的成員不同，分析是否產生女性特殊的住宅區位需求，其結果可以作為住宅政策的參考。 本文回顧相關文獻，發現單從經濟學的模式不足以說明家戶的選擇行為，而社會學與性別方面的議題和假說也未深入探討家戶的住宅區位選擇，因此考量現實的背景，希望從實證主義，剖析不同生命週期家戶的住宅調整方式，以及從大幅改變住宅屬性的遷移方式中，進一步解構家戶的住宅區位選擇行為與通勤的決策，並討論家庭責任、性別差異等相關課題。實證資料係採1990年台閩地區戶口及住宅普查台北市的資料，探討家戶對於自有住宅的調整決策，將台北市各行政區中位置相鄰、性質相近者分為六區，作為住宅區位選擇的替選區位。本研究以效用理論為基礎，分析家戶的遷移決策、遷移選擇一個新的住宅區位、以及增建決策等，追求家戶住宅需求效用的最大化，以不連續選擇模型進行實證。 結果發現高所得家戶選擇遷移的機率較高，低所得、或小孩正在成長的家戶較傾向選擇增建，住宅區位選擇的結果，也可印證人口往新興發展的郊區移動，老舊的西區流動性較差，應用在都市發展的政策上，可以針對資源的流動與新興地區的住宅及公共設施建設、交通運輸建設等相關政策做出建議。 另外，藉由女性的決策權力與需求的結果，發現女性就業的特性與所得資源對於區位、通勤選擇的影響力較低，反而是照顧小孩的家庭責任是關鍵因素，女性同時在外工作與擔任母職的角色，非常需要工作地點與住宅區為方便的連結，工作與居住分離的都市形式或許不敷台灣社會的需要，方便的交通與大眾運輸工具、以及價格合理且鄰近社區的兒童扥育設施都是女性急需的公共服務。 同時考慮夫妻兩位家戶成員的戶長配偶模式比傳統的戶長模式較能解釋住宅區位選擇的決策，但是在1990年當時的已婚女性多是無酬的家屬工作者或未就業，因此較沒有顯著的經濟影響力，惟獨年輕、教育程度較高的女性展現較不同於傳統的決策行為，而且以女性為戶長的家戶的確有孑然不同的區位選擇影響力，與台北市全體家戶、以男性為戶長的家戶相比，女性的戶長影響力較大。 / This dissertation consisted of four relative essays. Due to lack of housing adjustment decisions and location choice issues in Taiwan’s housing research, this study focus on some specific background in Taipei City, and reference to the existing studies. The relative resources and couple’s decision-making power effect is an important discussion point to which I drew attention. Using the discrete choice model and the data from “1990 Census of Population and Housing in Taipei”, the empirical studies are tested. As we known, the housing price in Taipei is the highest in Taiwan, households choose moving decision would pay higher adjustment cost. The most popular housing types in Taipei are apartments, the addition behavior without government permission is normally illegal. But under the constraint of affordability, some families would choose home improvement instead of moving to satisfy their housing needs for saving adjusting cost. In the first paper, I examined different choices of moving decision, housing location choice, and addition decision, which every household made. Households in different life cycle stages, indicating different income level, number of members, marriage status or other specific characteristics, they how to adjust their housing demand and make their housing decisions. The results will provide housing market segmentation information and explain the housing filtering behaviors. This second paper explores the effects on housing location choice in single and double income households in Taipei, and examines the relative hypotheses, such as relative resources and couple’s decision-making power, and household responsibility constrains. Households’ residential location choice are subjected to income constrains, facing the trade-off between housing price and commuting cost. Husbands who are usually the financial resources of a family economy get more decision- making power than wives. However, it would not play more significant role on location and commuting choices for wife to taking care of children. The results would suggest the government to provide convenient public transportation mode and children care service. The last two papers examine the impact of aggregated needs of household members on the choice of housing location in Taipei. Especially the discussion of family decision- making issues was raised. The results indicate that the choice of housing location is significantly impacted by the age, family origin, past housing location, education and occupation status, and the location of workplaces of both spouses.　We also find that this decision is more significantly influenced by the attributes of the male spouse□than the female.　However, among the households with a female household head, the female spouse□characteristics are more likely to be significant.　Our results also offer a snapshot of today□Taiwanese culture that is dramatically different from the commonly understood male-dominance in the Chinese tradition.
