Supply Chain Digitalization and Supply Chain Resilience: A Moderated Mediation Study

Abstract

This study examines how supply chain digitalization enhances supply chain resilience in disaster management organizations, with supply chain flexibility as a mediating mechanism and environmental uncertainty as a moderating condition. Data were collected from 315 professionals working in disaster management organizations, including the National Disaster Management Authority and Provincial Disaster Management Authorities in Pakistan. Data were analyzed using IBM SPSS Statistics. Pearson correlation and regression analyses were used to examine the proposed relationships, while PROCESS Models 4 and 7 were employed to test mediation and moderated mediation using 5,000 bootstrap samples. The findings demonstrate that supply chain digitalization significantly enhances supply chain resilience. Supply chain flexibility partially mediates this relationship, indicating that digitalization strengthens resilience partly by improving the ability of disaster management organizations to adapt their supply chain activities. Furthermore, environmental uncertainty significantly strengthens the indirect relationship between digitalization and resilience through flexibility. The conditional indirect effect becomes stronger as environmental uncertainty increases. This study integrates digitalization, flexibility and environmental uncertainty into a moderated mediation framework and extends understanding of how digital capabilities can build resilient disaster management supply chains in an uncertain environment. The findings provide useful insights for disaster management policymakers and managers seeking to strengthen preparedness, responsiveness and resilience through digital transformation.
