Abstract: As the core path of industrial upgrading and transformation, the inherent impact mechanism of the dual development of digitalization and greening on industrial chain resilience needs to be studied systematically. Based on clarifying the theoretical logic of how digitalization and greening coordination impacting industrial chain resilience, this study uses the panel data from 30 Chinese provinces (2012-2022) to conduct an empirical analysis. The findings show that, firstly, the synergy between digitalization and greenification can significantly enhance the resilience of the industrial chain, and the synergistic effect is superior to that of unilateral influence. The analysis of the mechanism of action reveals that technological innovation and infrastructure construction are the key to the enhancement of industrial chain resilience through the synergy between digitalization and greenification. By optimizing resource allocation, strengthening inter-industry collaboration, and enhancing risk resistance, the two jointly construct a channel for resilience improvement. The heterogeneity analysis reveals that in regions with higher levels of green credit, the synergistic effect of dualization on industrial chain resilience is stronger. In the eastern region, the impact of the dualization synergy on industrial chain resilience is more significant, while it is not significant in the central, western, and northeastern regions. To further enhance the resilience of the industrial chain, we should continue to improve the level of digital and green collaboration, increase support for technological innovation and infrastructure construction, and adopt differentiated strategies for regions with different levels of green finance development, as well as for the eastern, central, western, and northeastern regions, to promote the enhancement of industrial chain resilience.
