中文摘要:随着中国锑矿产量下降以及全球新能源领域对锑需求量的增加, 全球锑原材料供需格局正在改变。对全球锑原材料贸易格局的现状及演化过程开展分析, 有助于世界各国构建弹性的锑原材料供应链。本文基于物质流与复杂网络分析方法, 定量刻画了四类锑原材料(锑矿石、锑金属、锑初级加工品、再生锑)的全球贸易格局(2002—2020年), 分析了典型国家(地区)的锑原材料贸易结构及贸易地位变化特征, 总结了贸易格局的演化规律。研究发现: (1)锑初级加工品是全球最主要的贸易品种, 其贸易量占全球锑原材料总贸易量的一半以上; (2)中国和美国分别是贸易地位排名前两位的国家, 印度、欧盟、韩国是贸易地位上升最快三个国家(地区); (3)欧盟锑金属的进口来源呈现明显的多元化趋势, 显著降低了对中国的进口依赖, 表明欧盟近些年实施的关键原材料多元化进口战略取得了显著成效; (4)中国在全球锑原材料供应格局中的绝对优势地位在下降, 与此同时, 全球锑原材料贸易格局正朝着更加多元的方向发展。 |

Mapping the Evolution of the Global Antimony Raw Materials Trade Pattern |

Abstract:The global supply-demand pattern for antimony-containing materials is changing as China’s mine production declines and global demand for antimony-containing materials increases in new energy sectors. An analysis of the global antimony raw materials trade pattern can help countries build their own resilient supply chains of antimony raw materials. Using material flow and complex network analysis methods, this study quantitatively depicts the global trade pattern of four types of antimony raw materials (antimony ore, antimony metal, primary processed materials of antimony, and secondary antimony) from 2002 to 2020. Additionally, the evolutionary characteristics of the global antimony raw materials trade pattern and national status are analyzed. Primary processed materials containing antimony were found to be the most important type of commodity, with trade volumes accounting for more than half of the global trade volumes of antimony raw materials. China and the United States were found to be the two countries with the most comprehensive trade status, while India, the EU, and South Korea were the countries (regions) with the fastest rise in comprehensive trade status. The EU’s import sources of antimony showed an obvious diversification trend, which significantly reduced its import dependence on China, indicating that the EU’s import strategy of critical raw materials has achieved remarkable results in recent years. China’s absolute dominance in the global supply of antimony raw materials is declining with the development of a more diversified pattern of global antimony raw materials trade. |
