• 中文摘要： Based on the linear multiple regression results from Tsaur and Chang (1998), this paper examines family characteristics (e.g., family composition and size, living conditions, occupation of family-head, education, gender, and age) among different socioeconomic groups and their influence on the distribution of family income in Taiwan from 1980 to 1994. Empirical findings reveal that family attributes based on family income inequality differs significantly among socioeconomic groups. The results attributed to such variations include: (1) regression coefficients, (2) the magnitude of family characteristics, and (3) the inequality of relevant characteristics. For low-income households, family size, the number of employed family members, family-head age, as well as family-head education level largely impacts family income distribution. In comparison, in middle-income households, the number of employed family members, family-head education level, family size, as well as occupational status have the greatest influence. However, for upper-income households, family income inequality is sensitive to fixed asset level, the number of employed family members, family-head education level, and family-head age. This paper, therefore, analyses the characteristics of various household income levels as well as their influences on income in an effort to study the conditions and changes surrounding the distribution of household income in Taiwan.
• 英文摘要： 本研究藉用迴歸分析的結果（曹添旺與張植榕，1998），來探討台灣家庭各屬性在高低所得階層的分布狀況，及其對家庭所得分配的影響。研究結果發現，家庭屬性不均度對家庭所得分配不均度的影響，在各所得階層都有所不同。而造成各階層如此差異的原因在於：(1)迴歸係數不同；(2)擁有各屬性相對數量不同；(3)各屬性相對不均度不同。低所得階層之家庭人數、就業人數、戶長年齡與戶長教育程度等，對所得不平均度之敏感度最高。中所得階層以就業人數、戶長教育程度、家庭人數與戶長工作地區等，對所得不均度的敏感度最高。然而高所得階層卻以固定資產、就業人數、戶長教育程度與戶長年齡等，對所得不均度的敏感度最高。本研究分析，不唯驗證了高低所得階層家庭不同屬性的分布以及對所得的影響力不同，並且亦說明了台灣家庭所得分配的狀況與變化。
