在全球化與後工業化的推動下，世界各國普遍地經歷教育擴張與產業結構轉型，並帶動女性勞動參與率上升。這樣的現象也同樣出現在臺灣，行政院主計總處的統計資料顯示，婚後女性持續參與勞動市場的比例逐年提高。然而，相較於女性經濟地位的提升，家庭中的性別分工與男性養家者規範改變得較為緩慢。在過往西方研究指出，若以夫妻間相對收入衡量，男性在相對收入較低時，其主觀福祉通常較差，此現象可由相對資源理論與傳統性別角色觀點加以解釋。然而，在臺灣脈絡中，針對男性主觀福祉或是心理健康的探討仍相當有限。

因此，本研究欲探討：（1）在臺灣社會中，妻子的相對收入比例如何影響丈夫的生活滿意度？並進一步討論（2）家庭總收入是否調節妻子相對收入比例與丈夫生活滿意度之間的關係？本研究使用家庭動態調查資料庫（PSFD）2009年至2022年的追蹤資料，並將研究對象設定在處於異性婚姻狀態且屬於勞動市場的男性受訪者，進行長期追蹤資料分析。

研究發現，妻子相對收入比例對於丈夫生活滿意度呈現一種先升後降的倒U型曲線關係，且轉折點位於18.6％。當研究進一步討論家庭總收入的調節效果時，發現丈夫會因為身處家庭總收入位置的不同，使得妻子相對收入比例對於其生活滿意度進一步產生不同影響，在中收入組中，妻子相對收入效果影響較低收入組大。

論文外文摘要： Driven by globalization and post-industrialization, countries around the world have generally experienced educational expansion and industrial restructuring, which have also contributed to an increase in women’s labor force participation. A similar phenomenon has also occurred in Taiwan. Statistics from the Directorate-General of Budget, Accounting and Statistics, Executive Yuan, show that the proportion of married women who continue to participate in the labor market has increased year by year. However, compared with the improvement in women’s economic status, changes in the gender division of labor within families and the male breadwinner norm have occurred more slowly. Previous Western studies have indicated that, when measured in terms of relative income between spouses, men generally report lower life satisfaction when their relative income is lower. This phenomenon can be explained by relative resource theory and perspectives on traditional gender roles. However, in the Taiwanese context, research on men’s life satisfaction or psychological health remains relatively limited.

Therefore, this study aims to examine: (1) How does the wife’s relative income affect the husband’s life satisfaction in Taiwanese society? and, further, (2) Does total household income moderate the relationship between the wife’s relative income and the husband’s life satisfaction? This study uses longitudinal data from the Panel Study of Family Dynamics (PSFD) from 2009 to 2022 and focuses on male respondents who are in heterosexual marriages and remain in the labor market to conduct longitudinal data analysis.

The findings show that the wife’s relative income has an inverted U-shaped relationship with the husband’s life satisfaction, first increasing and then decreasing, with the turning point occurring at 18.6%. When the study further examines the moderating effect of total household income, the effect of the wife’s relative income on the husband’s life satisfaction differs depending on the household’s position in the total household income distribution. In the middle-income group, the effect of the wife’s relative income is greater than that in the low-income group.
