金属矿产资源是工业生产和经济发展的物质支撑。探究全球金属矿产贸易网络演化，对于理解全球金属矿产生产、流通和消费格局变化具有重要意义。论文运用中心性、网络密度、全局集聚系数、全局效率和视差滤波等网络分析方法，刻画全球金属矿产贸易格局时空演化，剖析全球金属矿产贸易网络拓扑结构，识别各国在全球金属矿产贸易网络中的地位和角色变化，为全面认知全球金属矿产贸易连通性、促进金属矿产贸易合作、维护全球金属矿产供应稳定提供有益参考。研究发现：① 全球金属矿产贸易中铁、铜、锌、钼和锰等矿产类型长期占据较高比重，总贸易规模呈现出波动中上升态势，局部区域贸易格局正在经历明显的空间重构。全球金属矿产贸易网络层级特征和空间不均衡态势逐渐显现，形成金属矿产贸易大国和贸易活跃地区相互联动并辐射带动其他区域的贸易格局。② 全球金属矿产贸易网络规模呈扩张趋势，网络的复杂化和稠密化态势明显，网络连通性和传输效率随网络扩张而显著提升。但部分国家可能会面临金属供应链中断的风险，全球金属矿产贸易网络应对冲击的稳健性仍有待提升。③ 全球金属矿产贸易网络骨干结构特征明显，部分关键节点和优势连边在网络中起到重要的支撑作用，以中国为核心的轴辐式骨干结构较为稳定，以欧洲和美洲国家为主体的骨干网络逐渐凸显并具有复杂化拓扑特征。④ 中国是全球金属矿产贸易网络的绝对核心，但进口和出口规模相差悬殊；德国和南非分别具有重要的全球金属矿产进口和出口影响力；澳大利亚、巴西和智利的出口规模以及日本和韩国的进口规模位居全球前列；荷兰、西班牙和加拿大等国发挥着重要的贸易枢纽作用。部分国家在全球金属矿产贸易网络中的位置有所调整，意大利的整体影响力和枢纽功能均显著下降，美国的金属矿产进口规模和印度的金属矿产出口规模分别略有降低，秘鲁逐渐跻身金属矿产出口核心国行列。最后，论文从提高金属矿产自给率和利用效率、优化金属矿产对外贸易合作格局、增强金属矿产贸易风险抵御能力及提升金属矿产供应端控制能力4个维度，提出促进金属矿产对外贸易合作、保障金属矿产供应安全的政策启示。

Metallic mineral resources provide the raw materials for industrial production and economic growth. It is critical to investigate the change of the global metallic mineral trade network to understand changes in global metallic mineral production, distribution, and consumption patterns. In this study, we employed various network analysis methods to portray the spatiotemporal change of the global metallic mineral trade pattern, analyze the topological structures of the global metallic mineral trade network, and identify the status and role of each country in the global metallic mineral trade network, to provide helpful information for understanding the stability of the global metallic mineral supply. The study found that: 1) The global metallic mineral trade, with iron, copper, zinc, molybdenum, and manganese accounting for a significant share, showed an upward trend amidst fluctuations, and the regional trade pattern is undergoing spatial restructuring. The global metallic mineral trade network has steadily developed hierarchical features and spatial imbalances, creating a trade pattern where major trading countries and active trading countries are interconnected and drive changes of other regions. 2) The scale of the global metallic mineral trade network is expanding, network complexity and density are increasing, and network connectivity is improved with the expansion of the network. However, some countries may face the risk of interruption of the metal supply chain, and the robustness of the global metallic mineral trade network to cope with shocks still needs to be improved. 3) The backbone structures of the global metallic mineral trade network are obvious, with some key nodes and edges playing an essential supporting role. The hub-and-spoke backbone structure with China as the core is relatively stable, while the backbone network with Europe and America as the main body is gradually becoming prominent and shows complicated topological characteristics. 4) China is the core of the global metallic mineral trade network, but there is a significant discrepancy between its import and export scales. Germany and South Africa have important global influence in terms of metallic mineral imports and exports, respectively. Australia, Brazil, and Chile lead the world in export scale, while Japan and the Republic of Korea rank high in import scale. Countries such as the Netherlands, Spain, and Canada play important roles as trade hubs. The position of some countries in the global metallic mineral trade network has been adjusted, with Italy's overall influence and pivotal function declining significantly, the metallic mineral import scale of the United States and the export scale of India decreasing, and Peru gradually ranking among the core metallic mineral exporting countries. Finally, this article put forward policy implications for promoting international trade cooperation in metallic minerals and ensuring the security of metallic minerals supply in China from four dimensions: improving the self-sufficiency rate and utilization efficiency of metallic minerals, optimizing the pattern of international trade cooperation in metallic minerals, enhancing the ability to resist the risks of trade in metallic minerals, and upgrading the ability to control the supply side of metallic minerals.
