Global supply chains, initially designed to enhance production efficiency and reduce costs through geographically dispersed networks, have evolved into complex global value chains (GVCs) characterized by deep interdependencies among countries and industries. According to Economic Interdependence Theory, higher levels of mutual economic dependence can influence both cooperation and systemic vulnerability, which are often underestimated—especially amid escalating geopolitical tensions. This study examines the resilience of global value chains by analyzing the structural positions of the US and China between 2012 and 2020. Using OECD Inter-Country Input-Output tables and a social network analysis (SNA) framework, it evaluates the network positions of 45 industries across 76 economies (excluding services), through three weighted centrality measures: degree, betweenness, and PageRank. These metrics allow us to (1) measure the degree of bilateral interdependence, (2) evaluate structural resilience to supply disruptions, and (3) uncover network-driven asymmetries in global economic power. Results indicate that China has significantly enhanced its resilience by diversifying industrial connections and expanding its structural centrality, thereby reducing vulnerability to external shocks. In contrast, while the United States remains integral to high-value nodes, its network position is more concentrated, which may expose it to greater risks under conditions of disruption or fragmentation.
