| 摘 要： | 铟资源广泛应用于ITO靶材、半导体化合物、焊料及合金等材料的生产制造,是21世纪重要的战略金属。文章基于铟资源全产业链视角,通过分析2000年以来全球铟资源供给与消费格局,并展望未来供需趋势,得出的结论主要有:(1)全球再生铟供给已超过原生铟供给;原生铟供给高度集中在中国、韩国、日本、加拿大四国;再生铟供给集中于日本、韩国。(2)全球铟资源消费量大幅增长,二十年来,翻了两番;日本与韩国是全球铟资源的消费主体;ITO靶材是主要消费领域。(3)2007年以来,全球铟资源总供给量大于总消费量600 t,预判这部分差量进入了国家储备。(4)未来中国增加铟资源供给的途经可以借鉴日本与韩国的经验,从社会存量中再利用铟资源,提高铟全产业链利用效率。

| Abstract: | Indium is an important strategic metal in the 21st century and is widely used in the production and manufacture of ITO targets, compound semiconductors, solders, and alloys. By considering the indium industry chain, this study analyzed global supply and consumption of indium since 2000. This study considered the future supply and demand trends, and concluded the following: (1) Global supply of secondary indium has exceeded that of primary indium. Primary indium sources are highly concentrated in China, South Korea, Japan, and Canada, whilst secondary indium sources are concentrated in Japan and South Korea. (2) Global indium consumption has quadrupled in the last two decades. Japan and South Korea are the main consumers of global indium resources, with ITO targets the main consumption area. (3) Since 2007, the global supply of indium has exceeded global consumption by 600 tons. The excess is predicted to enter national reserves. (4) China can learn from the experiences of Japan and South Korea to increase their future supply of indium, reuse indium from the social stock, and improve the utilization efficiency of the indium industry chain. |
