新发展格局下河北省数字产业集聚水平测度与地区差异研究

新发展格局下，数字产业集聚能够有效推动经济高质量发展和实现共同富裕目标。文章采用行业集中度、区位熵测度了河北省数字产业集聚水平，利用Dagum基尼系数探析了地区差异及来源。研究表明：行业集中度表明电信和互联网业主要集聚在石家庄、唐山、保定、廊坊和邯郸等地区；区位熵表明石家庄、廊坊、秦皇岛、张家口、承德等地区数字产业集聚优势明显。总体差距中，数字产业组间差距是造成总体差异的主要来源；组内差距中，欠发达地区数字产业发展差距在波动中上升；组间差距中，发达区和欠发达区之间差距最大，枢纽区与协同区差距最小。

Research on the Measurement of Digital Industry Agglomeration Level and Regional Differences in Hebei Province: A Perspective from the New Development Pattern

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.
