Abstract: Based on the provincial panel data from 2011 to 2020 in China,this paper makes a theoretical and empirical analysis on the impact of digital inclusive finance on multidimensional poverty and its mechanism.The research indicates an inverted "U" relationship between digital inclusive finance and multidimensional poverty and further analyzes the first-level sub-index of the development of digital inclusive finance.It is found that the inverted U-shaped relationship is more likely to be due to the "breadth of coverage" rather than the "depth of use" and "degree of digitization" of digital finance.Through the mechanism test,it is found that the poverty reduction effect of digital inclusive finance on multidimensional poverty is mainly realized by increasing the availability of credit and expanding the coverage of insurance or with other mechanisms or means.Through the test of heterogeneity,it is found that the turning point of the multi-dimensional poverty reduction effect of digital finance in western China lags behind that in eastern China.Therefore,in order to make full use of the poverty reduction effect of digital inclusive finance on multidimensional poverty,we should not only optimize the credit mechanism from both supply and demand sides and promote the development of digital insurance services,but also implement differentiated policies according to regional differences.

Key words: digital inclusive finance, multidimensional poverty, intermediary effect model, heterogeneity
