With the advent of the digital economy, the logic of value creation has gradually shifted from enterprise dominance to value co-creation, increasing the complexity of resource orchestration. Based on socio-technical theory, an ecosystem-level perspective was adopted to explore the enhancement of resource orchestration capability, and a theoretical model was constructed to examine the impact of the digital platform ecosystem on resource orchestration capability, incorporating the mediating role of structural holes. The results indicate that complementarity, shareability, modularity, and openness in the digital platform ecosystem positively influence resource orchestration capability. Structural holes serve as a partial mediator in this relationship. The findings contribute to theory by analyzing the interaction between the digital platform ecosystem and resource orchestration capability from a social network perspective, enriching research on resource management in digital platform ecosystems. On a practical level, the results offer important insights for platform enterprises in developing and optimizing their ecosystems to enhance resource orchestration capability.
