本研究企圖檢證雙薪家庭中，夫妻倆人各自於勞動市場上所佔有的階級位置的不同，是否會影響家庭事務決策模式以及家務分工的情況。我利用馬克思主義女性主義的觀點來作為女性投入勞動市場能否提升其家庭地位的理論基礎。利用台灣社會變遷基本調查（三期二次東亞組問卷）進行實徵研究。研究結果發現雖然階級位置並非決定家庭中夫妻權力關係的重大因素，但家庭階級位置組合與家庭事務的關係中，得出在家庭決策模式與家務分工這兩議題上，資產階級家庭會比其他階級組合的家庭有較不平等的性別關係。

　　　　　The central objective of this article is to explore the empirical relationship between the location of households in the class structure and gender inequalities in decision making of family affairs and performance of housework. We take the theory of Marxist feminists to view whether female can promote her family status by entering labour market. We argue that the linkage between the system of production, analyzed in class terms, and the family affairs, is at the heart of understanding the social process in gender relationship. As the complex relationship between class and family to unfold, there is basically no support for the view that class plays a pervasive role in family affairs, while economic factors do. By the way, our results still supported the fact: the social and gender inequalities are based on sex not class or something else.
