The operation principle of circular economy is analysed, subsequently the development mode of circular economy is summarized, then the cycle paths of aluminium industry economy get explored. Ultimately, combining advantages of circular economy with the particularity of aluminium production, an innovative input-output analysis model of aluminium circular economy and a detailed description for the practical application of the model are presented, providing a new way for sustainable development and structure adjustment of aluminium industry.%分析了循环经济的操作原理,归纳了循环经济的发展模式,探索了铝业经济的循环路径.把循环经济的优越性与铝业生产的特殊性相结合,创新性地提出了铝业循环经济投入产出分析模型,详述了此模型的实际应用,为铝业的可持续发展与结构调整提供了新途径.
