Abstract: In the digital economy era, the huge investment in digital resources and the scale and network characteristics of the digital economy itself determine that it is difficult for companies to complete digital transformation alone. With the continuous integration of network organizations and digital resources, the digital transformation of enterprise networks has become an inevitable trend. The company with digital advantages has become the leader of cooperation in the process of seeking external resources. A core enterprise network has been formed around this leader node, and each node in the enterprise network has a variety of digital features. The good reputation and digital capabilities of core node enable it to play a leading role, and its ability to absorb external resources is strong. They incorporate external nodes into their network through different connection methods, so that the digital information and resources connected to the corporate network can be used. It is transmitted to all nodes in the ecological network along the connection path between nodes. In addition, the continuous optimization of the digital resource configuration is realized by adjusting the cooperative connection, so that the enterprise network forms a virtuous and recyclable digital ecology, thereby realizing the digital transformation of the enterprise network.By sorting out the motivations of the digital transformation of enterprise networks, this study discusses the inevitability of digital transformation of enterprise networks, and analyzes the behavioral logic of core node and non-core nodes in the network surrounding digitalization. Based on the perspective of relationship embedding theory, the characteristics of digital transformation of enterprise network are explored through fuzzy set qualitative comparative analysis, and the transformation paths under different digital configurations are analyzed. The research results show that the digital transformation of enterprise network has various dimensions, superimposed on the combination of digital industrialization and industrial digitalization. In the process of transformation, the diversity of network connections under the weak connection mode is obvious, and there are more heterogeneous relationships. The core node has obvious requirements for digital technology, and the construction of digital infrastructure is still the main task of the digital transformation of enterprise network. The connection strength of such digital characteristic nodes is related to the attributes of the industry, and the digital transformation of enterprise network may have diffusion order at different industrial levels. Finally, the research results also show that small and medium-sized nodes are an important component of the digital transformation.The sample network has relatively rich digital features and connection forms, reflecting the diversity of the digital transformation path of the enterprise network and the behavioral logic of both nodes. When the overall strength of associated node innovation potential is weak, companies seeking future development and making up for their own technological research and development capabilities need to adopt strong cooperation and connection to digitally transform their traditional business and business models, while core node focus on the traditional business inventory of non-core nodes and their market share. When the scale of associated nodes is small and the motivation for innovation is limited, more attention is paid to the iterative upgrade of digitalization, and it is more flexible for them to cooperate with core node as service providers and suppliers. The core node also has continuous technical requirements for such non-core nodes. The flexible and diverse forms of weak connection can make it absorb more heterogeneous resources, so that the entire enterprise network has a steady stream of digital external resources. The connection between core node and non-core nodes also illustrates the requirements of enterprise network for resource allocation in the process of digital transformation. It is necessary to consider not only digital technology to support the digital transformation of traditional industries, but also support for digital industries in the process of rapid iteration. At the same time, an enterprise network should be open to other nodes with a higher level of digitalization. The digital transformation of enterprise networks needs to continuously improve the resource integration capabilities of the network system, so that nodes with different digital characteristics can coexist in this network, forming a digital ecosystem that is continuously upgraded.
