【Abstract】 By examining the impact of digital finance on the investment behavior of Chinese households in risky financial assets,the study finds that digital finance and its breadth of coverage, depth of use,and degree of digital support services not only promote more residents to invest in risky financial assets, but also increase the investment share of households that have already invested in risky financial assets.Further heterogeneity analysis shows that the effect of digital finance on households’ investment behavior in risky financial assets is mainly found in urban households,high-income households, and households in the eastern region. The intermediation effect analysis suggests that digital finance can stimulate households to engage in risky financial assets investment by increasing household income.Relevant authorities can improve the level of household wealth by increasing digital financial coverage in central and western regions,encouraging digital financial innovation by financial institutions,increasing the use of digital financial products by improving residents’ financial literacy,and guiding rural areas and low-income households to moderately participate in risky financial asset investments.更多还原
