Abstract：Abstract: As strategic fulcrums for cross-border e-commerce global expansion, overseas warehouse networks are profoundly reshaping the collaboration patterns of international supply chains. However, existing research mostly focuses on single-warehouse location and operation, leaving the mechanisms through which network structure drives supply chain collaboration largely unexplored. Integrating resource orchestration theory and dynamic capabilities theory, this paper develops a moderated mediation model, with resource integration capability as mediator and environmental dynamism as moderator, to systematically investigate how overseas warehouse network density, functional diversity, and connectivity affect supply chain collaborative performance. Using balanced panel data of 132 Chinese cross-border e-commerce firms from 2019 to 2025, we employ two-way fixed-effects models, bootstrap mediation tests, moderated mediation analysis, and panel threshold regression. Key findings: (1) Network density, functional diversity, and connectivity all positively and significantly influence collaborative performance, fully mediated by resource integration capability; (2) Environmental dynamism positively moderates the relationship between network structure and resource integration, implying that turbulent markets amplify the value of overseas warehouse networks; (3) Digitalization exhibits a double threshold effect: below 0.28, network structure has no significant impact; between 0.28 and 0.56, the coefficient is 0.19; above 0.56, it jumps to 0.37, with consistent patterns across network dimensions; (4) Heterogeneity analysis shows that the synergistic effects are stronger for manufacturing firms, SMEs, and firms operating in emerging markets; (5) Endogeneity tests using instrumental variables and propensity score matching confirm the robustness of findings. This study opens the black box of how overseas warehouse network structure affects supply chain collaboration, offering theoretical guidance for building agile and efficient overseas warehouse networks and providing empirical evidence for policy optimization.
