This paper makes use of the data of Chinese A-share listed companies from 2008 to 2020 to study the impact of enterprise digitalization on the layout of cross-regional supply chain of enterprises. The results show that enterprise digitalization can promote enterprises to increase their supply chain layout outside the province. The mechanism analysis shows that enterprise digitalization has reduced the supply chain management costs and communication costs of enterprises, thereby promote the enterprises to increase their supply chain layout outside the province. The analysis of regulatory effects reveals that the more concentrated a company’s supply chain and the greater its research and development intensity, the more it can enhance the promoting effect of enterprise digitalization on the cross-regional supply chain layout of the enterprise. Further research has found that compared to the traditional enterprises, the promotion effect of enterprise digitization on the cross regional supply chain layout of enterprises is more significant in high-tech enterprises. To this end, we need to leverage the positive role of digital technology in promoting the cross regional supply chain layout of enterprises, summarize and promote the typical cases of supply chain digitization, and cultivate and create personalized digital service providers.
