Research on the Evolution of Global Rare Earth Trade Network Pattern and the Relationship Between Competition and Cooperation
Rare earth is a key raw material for the development of strategic emerging industries in major countries.Clarifying the evolution pattern and competitive characteristics of global rare earth trade is of great strategic significance for seizing the commanding heights of future industrial development.Based on the perspective of the whole rare earth industry chain,the trade data of seven rare earth products from 1999 to 2022 were selected,and the clustering,centrality and community structure characteristics of the global rare earth trade network were analyzed by complex network analysis method.Competition intensity index and interdependence index were introduced to explore the competition and cooperation relationship in rare earth trade.The research shows that the scale of global rare earth trade continues to expand,the trade network space coverage is wider,connectivity and accessibility are gradually enhanced,with typical"small world"network characteristics.In the rare earth trade,the trend of a few countries occupying most of the trade links is becoming more and more obvious,and the difference in trade resources between nodes is very large.In addition,the rare earth trade is significantly divided into communities,but the composition of members within each community is unstable.From the perspective of competition and cooperation,the average competition intensity of rare earth trade has a small cyclical change,and the competition relationship is mainly reflected in the countries(regions)with a large volume of rare earth trade,and the interdependence tends to be low,and the trend of diversification of trade partners is obvious.On the whole,the competition and cooperation relationship between China and other rare earth trade participating countries(regions)is characterized by"high competitiveness and low dependency".
