The aging population is intensifying, and solving the problem of elderly care is urgent. This article is based on CHFS (2019) survey data, and empirical research has found that commercial pension insurance significantly promotes households' allocation of risky financial assets. The mechanism is tested using household risk perception and investment risk preference as mediating variables. In addition, through heterogeneity testing, it was found that the positive effect of commercial pension insurance on the allocation of risky financial assets is more significant in rural households with household registration, two sets of housing, and households in the northeast.
