We investigated how sibling status and sex of younger siblings influence Chinese adolescents' relationships with their fathers and mothers as a function of resource dilution and preference for sons. The sample included 1,093 adolescents from the 8th grade (M = 13.96 years, SD = 0.75 years; 47% girls) and the 11th grade (M = 17.25 years, SD = 0.74 years; 57% girls) in a longitudinal study. Consistent with expectations pertaining to the hypothesis of resource dilution and son preference in combination, girls with a younger brother reported less positive relationships with mothers than either singleton girls or girls with a younger sister. No significant difference was found between singleton boys and boys with a younger sibling. The current findings show implications that the resource-dilution theory and son preference culture together may place girls with a younger brother in an unfavorable condition of resource allocation.
我们调查了兄弟姐妹的身份和弟弟妹妹的性别如何影响中国青少年与父母的关系，这取决于资源稀释和对儿子的偏好。该样本包括来自八年级（M=13.96 岁，SD=0.75 岁；47%为女生）和十一年级（M=17.25 岁，SD=0.74 岁；57%为女生）的 1093 名青少年，这是一项纵向研究。与资源稀释和儿子偏好假设相结合的预期一致，有弟弟的女孩与母亲的关系不如独生女或有妹妹的女孩积极。独生子和有弟弟的男孩之间没有显著差异。目前的研究结果表明，资源稀释理论和儿子偏好文化的结合可能会使有弟弟的女孩处于资源分配不利的地位。
