The Difference of Parental Investment Model Between Multi-child Family and One-child Family

This study compared the parental investment patterns of multi-child families and single-child families. Through comparative analysis of the two family types, it is found that they have some differences in parental investment behavior. The results show that families with many children pay more attention to the cultivation of parent-child relationship, while families with only one child pay more attention to the cultivation of individual ability and independence. The research also found that the two kinds of families have differences in education investment, time investment and emotional investment, and different family types have their own characteristics and advantages in parental investment. These findings have important implications for understanding the differences in parental investment between different family types.
