Abstract Using the intelligent manufacturing pilot demonstration special action as a quasi-natural experiment, and employing data from Chinese A-share manufacturing listed companies from 2007 to 2023, this paper utilizes a multi-period difference-in-differences model to study the impact of intelligent manufacturing pilot demonstration projects on the degree of inter-industry linkage within enterprises. The results indicate that the implementation of intelligent manufacturing pilot demonstration projects significantly enhances the degree of inter-industry linkage within enterprises. Robustness checks, including the use of a multi-time-point propensity score matching difference-in-differences model and instrumental variable methods, further support the baseline estimation results. The findings of the mechanism test reveal that intelligent manufacturing pilot demonstration projects enhance the degree of inter-industry linkage within enterprises by improving the integration capabilities of the industrial chain and increasing investment in innovation. Additionally, the degree of product supply-demand matching, bargaining power, and the level of specialization in division of labor positively moderate the promotional effect of intelligent manufacturing pilot demonstration projects on the inter-industry linkage of enterprises. Further analysis results show that the effect of intelligent manufacturing pilot demonstration projects on improving the degree of connection between industrial chains is more significant in high-tech industries and non-state-owned enterprises. For enterprises with low concentration of suppliers and high concentration of customers, implementing intelligent manufacturing pilot demonstration projects can significantly enhance the degree of connection between enterprises industrial chains. This study evaluates the economic outcomes of smart manufacturing pilot demonstration projects from the perspective of industrial chain linkages, reveals the intrinsic mechanisms by which smart manufacturing impacts industrial chain linkages, and provides a theoretical basis for enhancing the resilience and security level of industrial and supply chains with smart manufacturing as the main direction.
