This article analyzed relevant theories to get better understanding of circular economy : ( 1 ) by adding " decomposer " to economic system, circular economy has built a circle of resource - products - recycled resource, by which the harmonization between economic and ecological systems is achieved. ( 2 ) three principles must be observed in circular economy, and they are reduce, reuse, recycle in turn. according to the order of the principles, the practice of circular economy must conduct cleaner production in enterprises, form ecological community of industry, and build " vein " industry
