本文利用民國89年戶口及住宅普查與家庭收支調查報告等資料來估計恆常所得、單親原因、家戶組成、家戶流動性等因素對於台灣單親家戶住宅租擁選擇之影響效果。我們先以家庭收支調查報告資料中之單親經濟戶長特性與單親家戶組成等因素估計單親家戶恆常所得方程式，然後再利用此方程式估計戶口普查資料中各單親家戶的恆常所得水準。實證結果顯示單親女性家戶擁有自住房屋的所得彈性大於單親男性家戶的所得彈性。此所得彈性隨著所得而增加。因喪偶造成目前單親狀態的家戶之擁有自住房屋的機率最高；因離婚及分居造成目前單親狀態的家戶之擁有自住房屋的機率最低。戶內幼齡人口數與男性戶長的擁有自住房屋機率呈現正向關係，但是與女性戶長的擁有自住房屋機率卻呈現負向關係。戶內非經濟戶長之老年人口數則對於擁有自住房屋的機率有正的影響。 This study uses 2000 census data and 2000 household revenue and expenditure survey data to estimate the effects of permanent income, the reasons for becoming single-headed, the composition of the household and the mobility of the household, on the tenure choices of Taiwanese single-headed households. We firstly estimate the permanent income equation of a typical single-headed household, using data from the household revenue and expenditure survey. The estimated permanent income equation is then used to measure the permanent income levels of the single-headed households in the census data. Empirical results suggest the income elasticity of female-headed households is greater than that of male-headed households. The income elasticity rises with income level. Households becoming single-headed simply due to the death of a spouse have a higher probability of owning a house compared to other types of households. The number of young children living in the household has a positive effect on the probability of a single male-headed household owning a house, but a negative effect on that of single female-headed households. The probability of owning a house rises with the number of old people living in the household.
