Abstract: Constructing resilient global supply chains to cope with exogenous shocks is a hot topic in current academic research. Previous studies have predominantly focused on the resilience of individual organizations or ecosystems, with little attention paid to inter-organizational dyadic relationships. Based on an analysis of the dyadic relationships between upstream and downstream entities of digital security enterprises, this study finds that transaction volume and relationship continuity in the past significantly enhance the resilience of inter-organizational dyadic relationships, while geographical distance weakens it. These effects exhibit regional and individual heterogeneity, and external shocks exert a moderating effect. This paper broadens the perspective and depth of resilience research, providing important theoretical significance and practical insights for the rational global deployment of supply chains and enhancing China's position embedded in global industrial chains.

Key words: inter-organizational dyadic relationships, relationship characteristics, resilience of inter-organizational relationships
