Promoting the development of core digital economy enterprises is the core engine for consolidating the foundation of digital economy development and driving high-quality economic development. Based on the data of core digital economy enterprises in 284 cities of China from 2000 to 2022 at the micro-enterprise level, this article uses the methods of the Mann-Kendall test, kernel density analysis, standard deviation ellipse analysis, and geographical detectors to reveal the spatiotemporal differentiation characteristics and influencing factors of core digital economy enterprises in China. The results show that: 1) The development of core digital economy enterprises in China exhibits the characteristic of phased transitions, with 2011 as an inflection point, transitioning from a "low-speed foundation-laying period" to a "high-speed growth period". The structure of digital core enterprises simultaneously diverges, with digital technology application enterprises accounting for the largest proportion, while digital factor-driven enterprises grow the fastest. 2) Overall, core digital economy enterprises in China present a stepped spatial distribution pattern of "high in the east of China and low in the west of China", while also exhibiting high regional agglomeration characteristics in the Pearl River Delta and Yangtze River Delta. 3) From the perspective of spatial distribution directionality and gravity center trajectory, the development of core digital economy enterprises in China exhibits a "southwest-northeast" contracting distribution, with the gravity center showing a spatial characteristic of "first shifting eastward and then northward". 4) Talent, innovation environment, and digital infrastructure factors are important factors explaining the spatial differentiation of core digital economy enterprises in China. Local governments should tailor measures to local conditions, combine regional endowments, and differentially arrange core digital economy industries. It should continue to optimize the innovation ecosystem and talent environment, enhancing their radiation ability in high-end digital industries in the eastern coastal areas. In the central and western regions, it should increase investment in digital infrastructure and focus on cultivating and introducing digital technology application industries that are integrated with local traditional industries, in order to narrow the regional digital divide and promote the balanced and coordinated development of China's digital economy.
