The rapid development of digital finance has profoundly reshaped household financial behaviors and wealth management patterns. Based on the micro sample data of 8

294 households from the 2021 China Household Finance Survey (CHFS)

this paper systematically explores the impact effect and transmission mechanism of digital finance on residents' household financial asset allocation.The research results indicate that digital finance can lower the entry threshold of financial markets and mitigate information asymmetry

thereby significantly increasing the proportion of households' risky financial asset allocation. Residents' risk preference exerts a significant partial mediating effect between the two variables. By enhancing residents' risk perception and risk tolerance willingness

digital finance can indirectly optimize the structure of household financial asset allocation. In addition

individual and household characteristics also impose significant constraints on asset allocation behaviors.This study clarifies the internal mechanism through which digital finance empowers household wealth management

and provides micro empirical evidence for improving the digital financial service system

guiding residents to rationally allocate financial assets

and expanding the channels of property income.
