Examining the factors that influence rural households’ wealth facilitates enhancing poor households’ happiness, improving their overall welfare, and narrowing the wealth gap between different households. Thus, this study analyzed data from the China Family Panel Survey (CFPS) using multiple linear regression and propensity score matching methods to examine the impact of natural disasters on rural household wealth. Our findings showed that natural disasters have a significant negative impact on rural household wealth, with a medium-to long-term effect. Additionally, the heterogeneity analysis indicated that natural disasters have a greater effect on the wealth of larger households and households with high-consumption levels. Mechanism results suggest that natural disasters affect rural household wealth by reducing household income and harming individual’s physical and mental health.

Based on the data from the 2012–2018 China Family Panel Survey, this study examines the impact of household wealth on individuals’ mental health using a two-way fixed effects model. The findings indicate that household wealth exerts a significant positive effect on individuals’ mental health. Furthermore, this study shows that the impact of household wealth on individuals’ mental health is nonlinear but inverted U-shaped. Considering the possible endogeneity problem, this study further examines the effect of household wealth on residents’ mental health using two-stage least squares, and the conclusions remain robust. The results of the heterogeneity analysis indicate that household wealth has a greater impact on the mental health of residents in the low-education group and western region. Furthermore, the results of the mechanisms reveal that household wealth affects mental health by influencing insurance investment and individuals’ labor supply. Moreover, this study finds that household wealth affects individuals’ mental health not only in the short term but also in the medium and long terms. This study provides policy implications for the government toward improving individuals’ mental health.
