Abstract: Accelerating the development of cyclic economy is essential to the national economic growth in China. Traditionally, the process of cyclic economy assessment at enterprises puts the emphasis on the macro-level rather than on the micro-level. Under such circumstances, based on the case study of a large domestic non-ferrous metal smelting enterprise, a comprehensive assessment indicator system of enterprise cyclic economy is construced by examining three chains of it, namely, input, consumption and circulation, and output. Meanwhile, it seeks to give a comprehensive analysis and in-depth interview on the expansion of cyclic economy by employing fuzzy mathematics theory and AHP theory. From the conclusion, it could be seen that the comprehensive assessment indicator system is able to demonstrate the development level of enterprise cyclic economy correctly.

Key words: cyclic economy assessment, non-ferrous metal smelting, in-depth interview
