Abstract: It is the inevitable requirement for achieving common prosperity to increase the property income of residents. Based on China Household Finance Survey (CHFS) from 2013 to 2019 and using the Probit and Tobit models, this paper conducts an empirical study. The findings show that financial literacy is an important factor affecting household property income. The improvement of financial literacy can not only improve the probability of increasing household property income, but also improve the proportion of the total household property income and the property income in the household total income. This conclusion still holds after changing the explanatory variable and deleting the samples of families with financial industry professionals and after the endogenous test using the average financial literacy of other households at the same income level in the same community as the instrumental variable. Compared with non-financial property income, financial literacy has a more obvious impact on the household financial property income, especially the non-deposit financial property income. The result of the mechanism analysis shows that raising the proportion of risky assets, increasing the rate of return on risky assets, promoting the holding of investment in real estate, and promoting land renting are four channels through which financial literacy affects household property income. Further analysis reveals that the marginal effect of financial literacy is more pronounced on the property income of the groups with lower income, which indicates that the improvement of financial literacy can promote the faster growth of property income of the low income groups and help them to accumulate wealth quickly, thus contributing to the realization of common prosperity. The above conclusion suggests that to improve household financial literacy, especially the low income families,is an important means to narrow the income gap, which is significant in realizing common prosperity.

Key words: financial literacy, property income, common prosperity
