| 中文摘要: |
| 将钨金属资源按照加工程度分为上游产品、中游产品、下游产品三种类型,同时基于2022年钨全球贸易数据构建一个复杂网络模型,然后对网络直径、网络密度和平均路径等关键指标进行分析,并进一步对2011-2022年下游产品贸易网络进行演化特征研究。研究结果表明:钨金属资源产业链全球贸易的绝大部分是下游贸易,且参与贸易的国家数量在不断增加,贸易联系愈加直接,市场规模逐渐扩大;上游主要集中在资源储量丰富且开采能力强的少数国家,中游由技术先进国家主导,而下游则更容易被市场需求和技术实力影响。基于以上结论,从产业结构、技术研发、贸易合作等方面对我国的钨贸易策略提出了相应的建议。 |
| 英文摘要: |
| Tungsten resources are classified into three types according to processing degree: upstream, midstream and downstream products. Based on the global tungsten trade data in 2022, a complex network model is constructed. Key indicators such as network diameter, network density, and average path length are analyzed, and further research is conducted on the evolution characteristics of the downstream product trade network from 2011 to 2022. The research results show that the vast majority of global trade in tungsten resources industry chain is downstream trade, with the number of countries participating in the trade increasing, trade contacts being more direct, and market size expanding. Upstream activities are mainly concentrated in a few countries with abundant resource reserves and strong extraction capabilities, while midstream activities are dominated by technologically advanced countries. Downstream activities are more susceptible to market demand and technological capabilities. Based on these conclusions, corresponding suggestions are proposed for China's tungsten trade strategy from the aspects of industrial structure, technological research and development, trade cooperation, etc. |
