Under the background of Internet,there have been new changes in the form and evolution of social capital,which have had a non-linear impact on high-quality economic growth in China.This paper first uses the super efficient SBM method to calculate the level of high-quality economic development including environmental fac-tors,and uses a dynamic panel model to estimate the impact of social capital on high-quality economic growth.From the perspective of financial development,using digital finance and traditional finance as interme-diary channels,this paper explores the mechanism by which social capital affects high-quality growth under the rapid popularization of the Internet.It is found that there is a significant non-linear relationship between social capital and high-quality economic growth.Social capital can have an impact on high-quality economic development through two intermediary channels,digital finance and traditional finance,and the mechanism of this channel changes under the regulatory influence of the Internet.
