Under the new development pattern, digital industry agglomeration can effectively promote high-quality economic development and achieve the goal of common prosperity. This paper measures the level of digital industry agglomeration in Hebei province by using industry concentration and location entropy, and analyzes the regional differences and sources by using Dagum Gini coefficient. The conclusion shows that industry concentration indicates that telecom and Internet owners mainly gather in Shijiazhuang, Tangshan, Baoding, Langfang and Handan. Location entropy shows that Shijiazhuang, Langfang, Qinhuangdao, Zhangjiakou, Chengde and other regions have obvious advantages in digital industry agglomeration. In the overall gap, the gap between digital industry groups is the main source of the overall difference; In the intra-group gap, the development gap of digital industry in underdeveloped areas rises in fluctuations; Among the differences between groups, the gap between developed areas and underdeveloped areas is the largest, and the gap between hub areas and collaborative areas is the smallest.
