摘要

本文以台灣婚友網站資料，計算出男女逐歲的擇偶年齡偏好上下門檻，發現：一、除女性的年齡上門檻外，其他三種年齡門檻皆隨年齡的增加而調降。二、男性約在33歲以後開始不能接受比自己年長的異性，女性約在28歲以後開始可以接受比自己小的異性。三、在25歲至33歲之間，男性與配偶的實際年齡差距較接近年齡偏好上門檻，女性的實際年齡差距則較接近下門檻。四、台灣男性比美國男性較不能接受年齡比自己大的女性，而30歲左右的台灣女性的年齡偏好比同齡美國女性更為嚴格。本文將以演化論與婚姻市場理論分析上述結果。

Previous studies of mating age preference thresholds usually use five ages as one unit and compare the thresholds among units to discuss the age effect and gender effect on the age thresholds. No studies have ever tried to compare the thresholds by each age. The present study statistically analyzes each age preference threshold from 20 to 44 years old by using the individual level data in a mate selection web site in Taiwan. The main findings are: (1) the younger a man is, the higher possibility (on average, before 33 years old) he can accept a mate older than himself. In contrast, the older a woman is, the higher possibility (on average, after 28 years old) she can accept a mate younger than herself. (2) Women between 26 to 34 years old have the strictest age preference (the narrowest gap between ceiling and floor age thresholds). (3) Comparing with an American sample (in a previous study), Taiwanese men have a lower ceiling age threshold. This means that the acceptance of an older mate for Taiwanese men is lower than American men. (4) Between 25 and 33 years old, the spouse's age difference of each age is near the men's ceiling age thresholds. In contrast, it is near the women's floor age thresholds. These results are discussed by using evolutionary theory and marriage market theory in the paper.
