摘　　要：基于2010—2020年31个省份面板数据,采用熵权TOPSIS与灰色关联度评价法、因子分析法分别测度数字贸易发展与区域创新综合指数,并运用耦合协调模型、Kernel密度估计分析数字贸易发展与区域创新耦合协调度的时空演进与分布动态,最后进一步考察耦合协调度的空间收敛性。研究发现,全国数字贸易发展与区域创新耦合协调度呈逐年上升趋势,东部与中部地区处于良好协调阶段,西部与东北部地区处于中度协调阶段,且地区间耦合协调度的绝对差异呈先扩大后缩小态势,其中仅中部地区不存在σ收敛,31个省份及四大地区均存在绝对β收敛与条件β收敛,且后者的收敛速度更快。Based on the panel data of 31 provinces from 2010 to 2020,the comprehensive index of digital trade development and regional innovation was measured by entropy weight TOPSIS,grey relational evaluation method and factor analysis method.Coupled coordination model and Kernel density estimation were used to analyze the spatio-temporal evolution and distribution dynamics of the coupled coordination degree of digital trade development and regional innovation.Finally,the spatial convergence of coupling coordination degree is investigated.The results show that the coupling coordination degree of national digital trade development and regional innovation shows an increasing trend year by year.The eastern and central regions are in a good coordination stage,while the western and northeastern regions are in a moderate coordination stage,and the absolute difference between the regional digital trade development and regional innovation coupling coordination degree is first expanded and then reduced.Finally,the convergence analysis shows that there is no o convergence in the central region,but there is absoluteβconvergence and conditionalβconvergence in the whole country and the four major regions,and the latter convergence is faster.
