Dr. Guangyue Gao’s research portfolio reflects a focused contribution to maritime economics, transport networks, and marine policy analysis, with particular emphasis on fairness–efficiency dynamics across regional scales. The scholarly record comprises 5 documents, which have received 3 citations, resulting in an h-index of 1. Core research outputs apply advanced network science and game-theoretic perspectives to global maritime transport systems, especially energy trade corridors. A notable award-winning study develops multi-layer network models of global maritime LPG trade using CEPII data and AIS big data, integrating supply–demand dynamics, maritime transport infrastructure, and relational trade structures. The work identifies dual-core structures led by major economies, highlights the strategic centrality of key maritime hubs, and reveals structural disparities and stability hierarchies across network dimensions. Overall, this research advances empirical understanding of global maritime energy trade, network robustness, and policy-relevant insights into marine economic systems and transport resilience.
