摘要
镍矿石由于其优良性能,被应用到人们生活中的各个领域,是一种非常重要的有色金属。国际镍矿石贸易国家众多,贸易关系错综复杂。文章利用复杂网络方法对UN comtrade(联合国统计司)发布的2006—2015年国际镍矿石贸易数据中的进出口国家以及贸易额进行建模分析。结果表明:2007年由于美国次贷危机引起全球金融危机的影响,全球经济萧条,各国贸易关系紧密度趋于松散,国际镍矿石贸易出口额大幅度降低,但是有越来越多的镍矿石资源国参与到国际镍矿石贸易当中来,贸易伙伴多样性丰富。在国际镍矿石贸易网络中,中国和美国在镍矿石贸易中的控制能力一直较强。2009年之后,全球经济开始复苏,国际镍矿石市场开始趋向稳定发展。
Nickel is an excellent widely-used non-ferrous metal. So many countries are involved in the international nickel ore trade, leading to a complicated trading relation. This paper uses complex network, based on UN Comtrade＇s 2006--2015 international nickel ore trading data to analyze the countries and trading quota. In 2007, due to the global financial crisis arising from America＇s Subprime mortgage crisis, the global international export of nickel ore largely declined, but more nickel producing nations got involved in this trade with more nickel trading partners. In the international nickel ore trading network, China and the United States have a strong control. After 2009, the global economy began to recover, the international nickel ore market commenced to stably develop.
