摘　　要：【目的】铟资源是中国战略性新兴产业发展的重要支撑原料,研究铟资源全产业链的价值流动现状及动态演变规律,对于中国铟资源安全保障及经济可持续发展具有重要战略意义。【方法】本文基于2019年中国铟资源的物质流动框架,利用价值链分析方法,根据要素价格理论,绘制出与铟资源物质流动过程相对应的中国铟资源价值流动图谱,以评价和分析中国铟资源全产业链的价值增减变化。【结果】(1)中国铟资源全产业链的总价值呈现出先上升后下降的倒U形变化趋势;(2)铟资源价值链中价值增值最大的环节为冶炼和精炼,增值额度分别为922%和1002%,这是由于技术、人力、能源等的投入促使铟资源品位大幅提升,同时铟作为伴生金属,其所伴生的金属锌价值相对较低;(3)中国虽然为世界铟资源储量的第一大国,但铟资源产业链依然依靠进口来维持发展;(4)对铟资源进行循环再利用,可带来十分可观的经济价值。【结论】因此,优化铟资源产业链、提升高端含铟产品的生产工艺和技术、加强含铟废品回收再利用等是提升中国铟资源价值量的重要途径。[Objective]Indium resources are an important supporting g raw material for the development of China's strategic emerging industries,and the study of the current status and dynamic evolution of the value flow of indium resources across the whole industry chain is of great strategic significance for the security of China's indium resources and the sustainable development of its economy.[Methods]Based on the material flow framework of China's indium resources in 2019,this paper utilizes the value chain analysis method and maps the value flow of China's indium resources corresponding to the material flow process of indium resources according to the factor price theory,in order to evaluate and analyze the changes of value increase and decrease in the whole industry chain of China's indium resources.[Results](1)The total value of China's indium resources industry chain shows an inverted U-shaped trend of increasing and then decreasing;(2)The stages with the highest value appreciation in the indium value chain are smelting and refining,with value increases of 922%and 1002%respectively.This is attributed to the substantial enhancement of indium resource grade due to the inputs of technology,labor,and energy,and that indium is a by-product metal with its associated zinc metal having relatively low value;(3)Although China is the world's largest country in terms of indium resources,the indium resource industry chain still relies on imports to sustain its development;(4)Recycling of indium resources can have significant economic value.[Conclusion]Therefore,optimizing the indium resource industry chain,upgrading the production process and technology of high-end indium-containing products,and strengthening the recycling of indium-containing waste products are important ways to increase the value of indium resources in China.
