| Since entering the new century,China’s economic construction has made great achievements,the importance of fairness and justice is increasingly prominent,the public’s perception of social fairness is crucial to social harmony and stability.At the same time,digital finance is combined with traditional financial service mode through Internet and other technical means,showing the advantages of low cost,high efficiency and wide coverage.It will have an important impact on promoting economic growth,alleviating poverty,narrowing the income gap and people’s income and consumption.Since the perception of social justice can be influenced by many factors,such as income level,education level,occupational status and relative deprivation,and the development of digital finance can affect the public’s real income,professional status and sense of relative deprivation,therefore,the development of digital finance may also have an impact on individuals’ perception of social justice.In this paper,in order to better sort out the possible influencing mechanism between the two,the channels through which the development of digital finance affects the perception of social equity are classified into structural determinism and relative deprivation theory.For this reason,this article uses the Chinese general social survey(CGSS)and Beijing university digital financial inclusion index,take the first year of the development of China’s digital finance as the boundary,through the construction of double difference model,from two structural determinism and relative deprivation theory,research on digital financial development to the public the influence of social justice perception and transmission mechanism,the results show that the development of digital financial can improve social justice perception of the public.And the promotion effect to the eastern region,rural residents is more significant.The intermediary mechanism test shows that the development of digital finance can improve the public’s perception of social justice by increasing income level and reducing the sense of relative deprivation.Through theoretical research,analysis of research status and empirical test,conclusions can be drawn: first,digital financial development can promote the improvement of the public’s sense of social justice;Second,digital finance plays a more significant role in improving the public’s perception of social fairness in eastern China,where digital finance has a higher degree of development.Third,digital finance can improve the public’s perception of social fairness by enhancing objective socioeconomic status and reducing the sense of relative deprivation caused by comparison with others.The following suggestions are put forward: First,vigorously support the development of digital finance;Second,focus on the construction of digital finance in central and western China and rural areas;Third,strengthen the publicity of financial knowledge and Internet knowledge. |
