내연기관차와 친환경차 무역네트워크 변화 분석: 2017년과 2023년 비교를 중심으로

초록

This study employs Social Network Analysis (SNA) to compare the structural evolution of global trade networks for internal combustion engine vehicles (ICEVs) and eco-friendly vehicles (EVs/HEVs), using UN Comtrade data from 2017 and 2023. The results show that the ICEV network remains relatively stable with limited structural change, whereas the eco-friendly vehicle network has rapidly evolved toward a more integrated and multipolar configuration. Over the study period, eco-friendly vehicle trade value increased approximately 7.9-fold, accompanied by a 1.7-fold rise in network density and a more than 1.5-fold increase in connectivity. Centrality analyses indicate the emergence of Germany, China, and South Korea as key hubs, reflecting a reconfiguration of the global trade axis during the industrial transition. These findings suggest that the current transition toward green mobility entails qualitative changes in trade-network architecture driven by supply chain restructuring, rather than a mere expansion of trade volume. This research provides a foundational framework for analyzing global supply chain policies in the era of green mobility.
