Social Network Analysis of the International Iron Ore Trade Pattern
基于2000-2013年国际铁矿石贸易数据，用社会网络方法分析网络密度、中心性和聚类系数，发现贸易关系紧密性不高，网络由澳大利亚、巴西等少数国家控制，中国影响不显著。
Based on the international iron ore trade data during the period 2000-2013, this paper analyzes the density,centrality and clustering coefficient of the international iron ore trade network by using the Social Network Method.These results show that: firstly, the tightness of the trade relation is not high. Although the international iron ore trade spreads nearly one hundred countries, its network is controlled by only a few countries such as Australia, Brazil.Secondly, Brazil, Australia, Japan and Germany occupy the important position in the international iron ore trade network,on which China does not have a significant impact. Thirdly, clustering coefficient of the international iron ore trade network has changed slightly, while the overall trend is downward rendering.
