Mr. Xiaodong Yan | Sustainable Agriculture | Best Scholar Award

Business School | China

Dr Xiaodong Yan is a doctoral candidate at the Business School of Hohai University in Nanjing, China, following an M.S. in Geographical Sciences from Liaoning Normal University and a B.S. in Hydraulic & Electric Power from Heilongjiang University. His research focuses on the coupling and spatial-transfer dynamics of the water-energy-food nexus, particularly in the context of Chinese provinces and inter-regional networks, as evidenced by several published articles including one in Resources, Conservation & Recycling. As of now, he has an h-index of 5, with 191 citations and 12 academic publications, reflecting his growing impact in the fields of environmental systems and sustainable development. Through his master’s research he demonstrated proficiency in tools such as ArcGIS, EViews and MATLAB, published five papers during that period, and received multiple honours including “Outstanding Graduates of Liaoning Province 2020”, “Outstanding Master’s Thesis” and “Outstanding Student Cadre”. His strong self-regulation, rigorous research attitude and critical-thinking skills underpin his work bridging resource-system modelling, input-output frameworks and ecological network analysis. Going forward he aims to deepen understanding of resource-system security and spatial nexus interdependencies, contributing to sustainable regional development.
