雖然公共領域的性別關係已逐漸趨向平等，家庭內的性別分工變遷卻相對緩慢，過往西方文獻指出，主觀家務公平感與實際家務分工在婚姻品質上具有不同的影響機制，但本土相關的量化研究仍有限。基於相關文獻的限制，本研究旨在探討主觀家務公平感與實際家務分工對婚姻品質的影響，回應台灣在此議題上鮮少同時考慮主觀與客觀家務分工對婚姻品質影響的研究現況。
本研究使用2021年台灣社會變遷家庭組調查資料，檢驗個人主觀家務公平感與實際家務分工對婚姻滿意度及夫妻衝突頻率的影響，並納入性別差異進一步分析。研究結果顯示：（一）個人主觀家務公平感愈高，婚姻滿意度愈高且夫妻衝突頻率愈低；相較於女性，主觀家務公平感對男性婚姻滿意度的影響效果較小，但在夫妻衝突頻率上則無性別差異。（二）個人家務時數占比愈高，婚姻滿意度愈低，但對夫妻衝突頻率無顯著影響；相較於女性，該比例對男性夫妻衝突頻率的負向影響效果較大，但在婚姻滿意度上無性別差異。（三）相較於女性，男性的婚姻滿意度較高；配偶教育程度愈高，婚姻滿意度亦愈高；家庭月收入愈高，婚姻滿意度亦隨之提升。
研究結果有助於理解台灣社會中，不同家務衡量指標在婚姻品質上的影響差異與共通之處。

While gender relations in the public sphere have gradually moved toward greater equality, changes in the gendered division of labor within households have progressed at a comparatively slower pace. Previous Western studies have shown that perceived fairness in housework and the actual division of housework influence marital quality through distinct mechanisms. However, quantitative research on this topic within the Taiwanese context remains limited. To address this gap, the present study examines the effects of perceived fairness in housework and the actual division of housework on marital quality, responding to the scarcity of research in Taiwan that simultaneously considers the impacts of both subjective and objective divisions of housework on marital quality.
Using data from the 2021 Taiwan Social Change Survey (Family Module), this study investigates the impact of individuals’ perceived fairness and actual household labor division on marital satisfaction and the frequency of marital conflict, with further analysis of gender differences. The findings reveal that: (1) higher perceived fairness is associated with greater marital satisfaction and lower marital conflict frequency; compared with women, perceived fairness has a smaller effect on marital satisfaction among men, but there is no gender difference in its association with marital conflict frequency. (2) A higher share of individual household labor hours is associated with lower marital satisfaction, but has no significant effect on marital conflict frequency; compared with women, this share has a greater negative effect on marital conflict frequency among men, but no gender difference is found in its relationship with marital satisfaction. (3) Men report higher marital satisfaction than women; higher spousal educational attainment is associated with greater marital satisfaction; and higher monthly household income is also linked to higher marital satisfaction.
The results contribute to understanding the differences and commonalities in how distinct measures of household labor influence marital quality in the context of Taiwanese society.
