通过采用社会网络分析方法,选取了1990年、1995年、2000年、2005年、2010年、2012年6个年度的数据,通过计算网络密度、中心性、点度数和聚类系数指标,对国际稀土贸易格局进行分析,得出结论:国际稀土贸易的网络比较稀疏。联系并不紧密;中国和俄罗斯因稀土储量优势成为国际稀土贸易中重要的出口国;美国凭借稀土资源和技术双重优势成为国际稀土贸易中重要的出口国:日本、荷兰、德国、英国、奥地利因拥有技术优势也是国际稀土贸易网络中的核心节点。
Based on the international rare earth trade data in the period of 1990, 1995, 2000, 2005, 2010 and 2012, this paper studies the density, centrality, core nodes and clustering coefficient of international rare earth trade net. The results show that: the international trade in rare earth net is relatively sparse,-not closely linked; China and Russia become important exporters in trade net due to their rare earth reserves; The United States becomes an important exporter of rare earth in international trade with dual advantages of rare earth resources and technology; Japan, Holland, Germany, Britain and Austria become the core nodes of international rare earth trade net because of the technological advantages.
