Research on the Influence of Children's Dependency Ratio on Marital Stability under the Stratification of Residents' Disposable Income

Based on the panel data of 31 provinces and cities from 2015 to 2023, this paper first uses the STATA software to construct a fixed-effects model to explore the significance of the interaction effect between the 10-year lagged child dependency ratio and the current disposable income of residents. Through analysis, it is concluded that the current disposable income of residents has a significant moderating effect on the influence of the lagged child dependency ratio on the stability of marriage.
