Analyzing 1268 stratified random samples from one of the biggest cities in China’s Pearl River Delta with the zero-inflated Poisson model, this study identifies the factors associated with the onset and severity of spousal violence by males and females separately under the social exchange perspective. The results indicate that spousal violence follows gender symmetry in migrant families, and violence against men is mainly reflected in psychological violence. The new pattern of “cradle snatching” makes men fully protected in family relationships. However, women’s education level and economic independence do not represent a protective factor against violence from husbands. Patriarchal cognition is deeply rooted in migrant families, even though the family pattern has been changed and women’s status has improved in China. Young couples should contribute to the family according to their own abilities, and should not make either one feel wronged.
