    With the advent of the digital economy era, human production and life are becoming increasingly informationized, networked, and intelligent. Digital economic activities play a significant role in improving production efficiency and reducing transaction costs. The digital process is reshaping how people interact, changing the social and economic structure and traditional business models. In recent years, the scale of China's digital economy has steadily increased, and its supporting role in the national economy has become increasingly prominent. The digital economy has shifted from a new driving force for high-quality economic development to a key development factor. Integrating data and traditional elements brings new opportunities for optimizing market-oriented allocation methods and expanding enterprises' production space from physical to network space. The development of the digital economy has enhanced economic connections between provinces in China and has had a profound impact on building a new pattern of regional economic development and promoting high-quality economic development. Against the backdrop of significant changes in the spatial way of digital economy development, studying the provincial correlation laws and influencing factors of China's digital economy has theoretical and practical significance.

    Data resources are the critical component of the new form of economy known as the digital economy. From 2014, when the concept of "big data" was first written in our report on the work of the government, to 2020, the central government regarded data as one of the five elements to promote the development of the national economy. China's digital economy is developing at an unprecedented speed and has an unparalleled degree of influence under the guidance of national macro policies. Therefore, this study chooses 2014-2020 as the sample period and calculates China's digital economy's connection strength and spatial imbalance by building a Gravity model and using the Theil index. It uses social network analysis methods to compare and analyze the structural characteristics of China's digital economy regional connection networks. It also uses the secondary assignment procedure to empirically test the factors affecting the regional connection of the digital economy. Research has found that: Firstly, the connection strength of China's digital economy has been increasing yearly, and there is significant spatial differentiation.The economic connections between provinces have a non-bidirectional and spatial adjacency. The eastern area of China significantly impacts the general variation in the strength of digital economic ties. In contrast, the impact of the central and western regions on the overall difference is very weak. Secondly, the spillover effect of China's digital economy development has significantly improved. The number of provinces in the center of the related network is increasing. The control ability of a single province on the overall network tends to weaken, and there are always isolated economic development nodes in the network. Thirdly, the digital economy network in China has formed four major sectors, with close connections between sectors and weak internal connections. The role played by most provinces in the network is sustainable. Fourthly, regional differences in economic development levels are a crucial factor affecting the regional correlation of China's digital economy. The spatial correlation of the digital economy will decay with the increase in geographical distance. The digital industry, enterprise operating environment, and industrial structure are essential in establishing digital economic connections. However, the regional differences in the digital foundation during the sample inspection period have no significant impact on the regional correlation of the digital economy. Therefore, this article proposes to strengthen the construction of digital infrastructure in underdeveloped areas, formulate regional differentiation development strategies for the digital economy, improve the overall development level of China's digital economy, and establish a regional coordinated development linkage mechanism.
