The entropy weight method and the modified coupling coordination model are used to calculate the coupling coordination of digital economy and high-quality economic development in 11 districts and cities in Hebei Province from 2014 to 2020. The results show that the coupling and coordination degree between digital economy and high-quality economic development in Hebei Province is on the rise during the study period, and the overall evolution situation of "antagonism-running in" is shown, specifically, the relative development trend of "digital economy lags behind high-quality economic development-synchronous development". The degree of coupling and coordination of Shi jiazhuang, Baoding and other cities with districts is high , while the degree of coupling and coordination of Hengshui, Chengde and other cities with low quality development of digital economy and economy is low.
