Abstract：This study investigates the mechanism through which digital and intelligent transformation promotes servitization in manufacturing from a supply chain network perspective.Utilizing a three-tier supply chain panel dataset of Chinese listed manufacturers (2012-2023),the paper examines the informational spillover effects of such transformation along the supply chain.The results demonstrate that:①Digital and intelligent transformation not only enhances a firm's own servitization level but also exerts significant spillover effects on upstream and downstream firms,thereby facilitating the servitization of focal enterprises.②Supply chain integration serves as the core mechanism:upstream transformation promotes servitization through technology diffusion and information sharing,whereas downstream transformation drives it via demand transmission.③The servitization-enhancing effect exhibits notable supply chain heterogeneity,becoming more pronounced in highly concentrated networks.Both supplier and customer concentration significantly amplify the spillover effects of digital and intelligent transformation.
