Research on the Heterogeneity of Internal and External Double Circulation Synergy from the Perspective of Digital Finance
Based on the panel data of Chinese provinces from 2011 to 2020,a finite mixed model with ac-companying variables was introduced to analyze the heterogeneous characteristics of the impact of provin-cial industrial upgrading and technological innovation on the coordinated development of internal and exter-nal double circulation under the influence of digital finance.The research results show that a finite mixed model containing three modes can be used to finely characterize heterogeneity characteristics.As an accom-panying variable,digital finance can significantly enhance the promoting effect of industrial upgrading and technological innovation on the coordinated development of internal and external double circulation.
