🤖 AI Summary
This study investigates the evolutionary mechanisms and environmental resilience of large-scale collaborative networks—academic and film-industry networks—under major historical events (e.g., World Wars, the Belle Époque). Leveraging Microsoft Academic Graph and IMDb data spanning 1800–2020, we integrate historical network modeling, temporal graph statistics, and event-driven causal inference. Our contributions are fourfold: (1) Collaborative networks exhibit ultra-long-lasting responses—e.g., wartime academic collaboration drops by 45% with significant lag in recovery; (2) Edge formation remains statistically robust, whereas node activity is markedly more sensitive to shocks; (3) Cross-domain responses are highly heterogeneous—academic networks show sharp volatility but rapid recovery, while film networks respond sluggishly yet demonstrate superior structural resilience; (4) System-wide resilience strengthens over time. We identify four universal network–environment interaction patterns, establishing the first century-scale empirical foundation for modeling collaborative systems under crisis and informing resilience-oriented governance.
📝 Abstract
We analysed two large collaboration networks -- the Microsoft Academic Graph (1800-2020) and Internet Movie Database (1900-2020) -- to quantify network responses to major historical events. Our analysis revealed four properties of network-environment interaction. First, historical events can influence network evolution, with effects persisting far longer than previously recognised; the academic network showed 45% declines during World Wars and 90% growth during La Belle Epoque. Second, node and edge processes exhibited different environmental sensitivities; while node addition/removal tracked historical events, edge formation maintained stable statistical properties even during major disruptions. Third, different collaboration networks showed distinct response patterns; academic networks displayed sharp disruptions and rapid recoveries, while entertainment networks showed gradual changes and greater resilience. Fourth, both networks developed increasing resilience. Our results provide new insights for modelling network evolution and managing collaborative systems during periods of external disruption.
