| 中文摘要:锡金属作为我国在发展战略性新型产业的重要矿产资源,具有重要的战略价值。我国是全球的最大锡消费国,并且在经济全球化的背景下,我国的锡矿贸易链的每个环节都需要通过国际贸易和其他国家进行内部系统与外部系统之间的交流。本文基于2019年全球锡贸易数据,出于我国对锡矿有巨大消费需求,从锡的贸易交流出发,把含锡商品进行上游、中游、下游商品类型进行划分,并据此构建锡矿的复杂贸易网络,计算了锡矿的出度、入度、加权度和中介性等指标,从三个层面、多个指标分析全球锡产业链和重要国家的贸易特征。主要的结论有：锡产品的贸易交流大多集中在中下游贸易活动中,仅有少部分国家参与了上游锡产品的贸易流通。2019年,中国在含锡产品的上中下游产品贸易网络中具有极强的控制能力。 |

| Abstract:Tin, as a crucial mineral resource in developing strategic new industries in China, has important strategic value. In the context of economic globalization, every link of China’s tin trade chain needs to communicate between internal and external systems through international trade and other countries. Based on the global tin trade data in 2019, in view of China’s tremendous consumption demand for tin ore, starting from the trade exchange of tin, this paper divides the upstream, midstream and downstream commodity types of tin containing commodities, constructs a complex trade network of tin ore, and calculates the export, import, weighting and intermediary indicators of tin ore from three levels. The main conclusions are: most of the trade exchanges of tin products are concentrated in the middle and lower reaches of trade activities, and only a few countries participate in the trade circulation of upstream tin products. In 2019, China has strong control over the upstream, midstream and downstream product trade network of tin containing products. |
