运用复杂网络方法,以2007—2014年国际铜矿石贸易量为数据,通过建立研究对象的加权网络和随机网络,从贸易整体格局、贸易社团化和主要贸易国地位三个方面对铜矿石贸易格局进行研究。结果表明,国际铜矿石贸易存在小世界特性,且具有明显的层次化特征,中国、美国和秘鲁之间的贸易关系日趋稳定,德国、英国和西班牙等国家倾向于形成一个贸易群,其他国家之间的贸易关系变动相对较大;中国、日本作为铜矿石进口大国,智利、秘鲁作为铜矿石出口大国,美国、南非作为贸易桥梁,这些国家在国际铜矿石贸易中均以不同国家角色成为贸易核心地位国家。还有一些贸易市场份额较小的国家,它们的贸易影响力大都由它们的贸易合作国决定。 By using the complex network method and the international trade volume of copper ore from 2007 to 2014 as the data, the paper establishes the research object weighted network and stochastic network from three aspects of the overall trade pattern, the trade community and the status of the major trading nation. Trade pattern research. The results show that the international copper ore trade has the characteristics of a small world and has obvious hierarchical characteristics. The trade relations between China, the United States and Peru are increasingly stable. Countries such as Germany, the United Kingdom and Spain tend to form a trading group. Other countries China and Japan, as big copper ore import countries, Chile and Peru as major copper ore exporting countries and the United States and South Africa as trade bridges, all of which have different countries in terms of international trade of copper ore with different countries Role becomes the core trade country. Still other countries with smaller share of the trade market, whose trade influence is largely determined by their countries of trade cooperation.
