Abstract: 【Purpose/significance】In the era of VUCA, mining the driving factors that promote the diffusion of enterprise digital trans⁃ formation is crucial to promote the rapid development of digital economy.【Method/process】This article applies simulation analysis, complex network and evolutionary game comprehensively to build the evolutionary model of enterprise digital transformation diffusion in the case of complex network and the presence of technology transfer, respectively. And we discuss the influencing factors of enter⁃ prise digital transformation diffusion.【Result/conclusion】Network structure, enterprise digital transformation success rate, and gov⁃ ernment subsidy rate have a significant impact on enterprise digital transformation diffusion. The initial proportion of successfully digi⁃ tized enterprises can weaken the role of government subsidy and enterprise transformation success rate. In addition, increasing the pro⁃ portion of enterprises with independent R&D capabilities in the network and the willingness of enterprises to transfer and purchase technology effectively increases the diffusion rate of enterprise digital transformation. Government subsidies effectively increases the willingness of enterprises to transfer and purchase technology. High technology transfer costs, while helping to stimulate the willing⁃ ness of enterprises with independent R&D capabilities to transfer technology, significantly inhibit the willingness of other enterprises to purchase technology.【Innovation/limitation】This article reveals the evolutionary pattern of the diffusion of enterprise digital trans⁃ formation, which can provide suggestions for relevant policy makers and enterprise managers to promote digital transformation.
