Dynamic evolution characteristics and influencing factors of global new energy vehicle trade network
The internationalization of China's new energy vehicles is related to the sustainable development of the automobile industry,so it is necessary to grasp the international trade struc-ture of new energy vehicles.Based on the social network analysis method,the global new ener-gy vehicle trade data from 2017 to 2020 were selected as samples to study the structural charac-teristics of the trade network and analyze the influencing factors of trade network with the Qua-dratic Assignment Procedure(QAP)method.The study shows that:(1)The global new energy vehicle trade network has low density and reciprocity & high correlation;(2)There is a high over-lap of countries with high centrality,high core degree and active both internal and external trade in the network,and three core regions-Europe,North America and East Asia based on the Unit-ed States,Germany,Belgium,Japan and South Korea-have been formed with significant region-al synergies;(3)Economic differences contribute to the establishment of trade relations but play a weakening role,industry chain complementarity contributes to trade intensity,harmonization of policies and consensus building have a more significant effect on trade than tariff preferences,and geographical distance hinders trade establishment and plays a stable role.The COVID-19 has accelerated the above trends and significantly increased the impact of the factor of land prox-imity.Therefore,the Chinese government should strengthen regional cooperation,increase infra-structure investment,and apply policies flexibly to avoid over-reliance on subsidies.
