【 摘 要 】

Circular economy system of energy and heavy chemical industry park is usually assessed by efficiency, economy and environmental impact indicators. Few studies have focused on the integrity and comprehensiveness of system operation. Based on energy value theory, we develop four indices, namely, energy yield ratio, environmental loading ratio, energy index of sustainable development and energy conversion ratio. These indices are then applied to comprehensively evaluate circular economy systems with different media and capacity. An empirical analysis is conducted to the circular economy system of Energy and Heavy Chemical Industry Park in Jinjie of Yulin City at different development phases (initial phase, 1st phase and 2nd phase). The results show that as the system is being constantly improved and updated, the overall performance increases, and the capacity of the system for sustainable development increases dramatically. In the meantime, the energy investment ratio has been rising, though the environmental loading ratio is relatively high. It is necessary to increase the ecological efficiency of the system by expanding and enriching the ecological chain of the system.
