In order to clarify the factors that affect intergenerational relationships, this paper collects data through questionnaire surveys and uses SPSS statistical software to analyze the intergenerational relationships between economically independent adult children and their parents. The results found that the three factors of native family type (p value <0.01), marital status (p value <0.01) and monthly income (p value <0.05) all had a significant impact on intergenerational relationships. The nuclear family, unmarried, low‐income adult children have close relationships with their parents, and the intergenerational relationship between the main family and the joint family, divorced and widowed, and high‐income children and their parents is general and even conflicts.
