Urban virtual agglomeration of digital indus-try is a new form of spatial organization of digital industry.This paper evaluates the current status of virtual agglomeration of dig-ital industries in 284 cities from 2011 to 2021 using multi-source data such as digital enterprise big data,Baidu index,and online business transaction index,and examines the regional differences,dynamic evolution,and convergence of virtual ag-glomeration of digital industries with the help of Dagum's Gini coefficient,kernel density estimation,the coefficient of variation method,and the spatial Durbin model.The study found that:First,the level of virtual agglomeration of digital industries in the country shows a steady increase in the development trend.Specifically,the concentration level is the highest in the eastern region,and decreases in the central and western regions.Sec-ond,in terms of regional differences,the intra-regional differ-ences in the East and West are higher than the intra-regional differences in the Central and Northeast,and the inter-regional differences between the East and the Northeast are the largest,while those between the West and the Northeast are the smallest.The inter-regional differences are the main source of the overall differences in the virtual agglomeration of digital industries.Thirdly,the spatial polarisation of the virtual agglomeration of digital industries in the country and the four major regions is not prominent,and the distribution curve is shifted to the right,with a right-dragging tail.Fourthly,the country,the east,the west,and the northeast as a whole have the characteristic of α-convergence,and the central region does not have the character-istic of α-convergence,and the absolute spatial β-conver-gence and the spatial conditional β-convergence are both mani-fested in the country and the four major regions,and the conver-gence of β-convergence is not significant in the four major re-gions,and after considering the spatial conditional β-conver-gence is accelerated after considering spatial conditional β-con-vergence.
