Abstract

In the context of the digital economy, collaborative advancement among enterprises has become an important driving force for promoting the overall digital upgrading of industrial chains. This paper adopts a supply chain perspective to analyze the spillover effects of corporate digital transformation between upstream and downstream firms. The empirical results indicate that supplier digital transformation significantly accelerates the digitalization of customer firms. This spillover effect is particularly pronounced under specific conditions: in high-tech industries, among firms with more advanced digital capabilities, and when suppliers and customers are geographically proximate and exhibit less divergence in their R&D strategies. Mechanism analyses further indicate that suppliers’ digital upgrading enhances customer firms’ innovation capability and willingness to adopt digital technologies by optimizing resource allocation, improving the efficiency of information flows, and facilitating technological diffusion. Based on these findings, this paper recommends strengthening resource integration and information sharing between upstream and downstream enterprises, thereby fostering a pattern of jointly promoted digital transformation along the supply chain. At the same time, differentiated supporting policies should be designed in light of firms’ digital foundations and the degree of R&D strategic alignment, so as to guide and coordinate corporate digital transformation in a more scientific and orderly manner.
