基于复杂网络的国际铜矿石贸易演变规律研究

    Research into evolution of international copper ore trade based on complex network theory

    • 摘要: 铜矿石是工业发展广泛需要的金属矿藏,铜矿石贸易对世界工业发展起到影响作用。参与国际铜矿石贸易的国家众多、贸易关系复杂,本文根据复杂网络理论,采用UN comtrade(联合国统计司)发布的2000~2012年国际铜矿石贸易数据,构建以国家为节点,国家之间的铜矿贸易关系为边的世界铜矿石贸易网络,分析了国际铜矿石贸易网络的时间演变规律。分析结果表明,铜矿石进出口国家数量趋于稳定,但进出口国家间的交叉联系增多,进出口贸易额呈现波动增长。2007年受金融危机影响,铜矿石贸易额下降。2009年后,在全球经济复苏局势下,国际铜矿石贸易进入强劲增长期,贸易全球化趋势更加明显,贸易中转国地位下降,同时中国的铜矿石贸易地位自2007年以后不断提升。

       

      Abstract: Copper ore is an importantmetal for the world’s industrial developing so the world's copper ore trade influencesthe world industrial development.Many countries participate in international trade in copper ores and copper ore international trade relationsis complex,according to the theory of complex networks,building the international iron ore trade data published by UN COMTRADE (UNSD) from 2001 to 2010 into the world trade network,analyzed the evolution of international copper ore trade network.The results show that the number of copper ore importing and exporting countries is stabilized,but the cross-links between importing and exporting countries are increasing,trade is fluctuated growth.Affected by the financial crisis in 2007,copper ore trade declined.After 2009,the situation in the global economic recovered,the International Copper ore trade into a strong growth phase.Transit trade power status decline,China became the world’s largest copper ore importsin 2009,occupies an important position in world trade in copper ore.
