摘　　要：基于2011—2020年中国省域面板数据,引入带有伴随变量的有限混合模型,分析数字金融作用下省域产业升级、技术创新对内外双循环协同发展影响的异质性特征。研究结果表明,可以利用包含3种模式的有限混合模型对异质性特征进行细致刻画,作为伴随变量的数字金融可显著强化产业升级、技术创新对内外双循环协同发展的促进作用。Based on the panel data of Chinese provinces from 2011 to 2020,a finite mixed model with accompanying variables was introduced to analyze the heterogeneous characteristics of the impact of provincial industrial upgrading and technological innovation on the coordinated development of internal and external 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 accompanying 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.
