The effect of blockchain on construction supply chain resilience: A mediated moderation model

In the era of globalization, enhancing construction supply chain resilience (CSCR) has become essential. Traditional supply chains face issues like information asymmetry, trust deficits, and inefficiencies, weakening their resilience. Blockchain offers a solution by improving transparency, trust, and coordination, but its impact on CSCR remains unclear. This study addresses the gap by developing a moderated mediation model to explore how blockchain influences CSCR through supply chain integration and the moderating role of environmental uncertainty. Data from 310 senior managers in Chinese construction firms were analyzed using structural equation modeling. The results showed that blockchain significantly improves CSCR, mediated by operational, informational, and relational integration, particularly under high uncertainty environments. The findings highlight blockchain’s potential to strengthen CSCR and provide theoretical insights into its mechanisms, offering practical guidance for construction companies to enhance supply chain processes through blockchain implementation.
