循环经济是包含多投入和多产出的复杂经济系统,客观、有效的循环经济效率评价体系是反映循环经济发展的关键。文章根据循环经济的3R原则,构建了评价西部各省区市循环经济发展效率的指标体系,并运用动态DEA模型对西部各省区市循环经济综合发展效率进行评价。对西部十一省区市2010年数据进行分析,分别从投入和产出角度分析影响循环经济效率的主要因素,指出非DEA有效地区循环经济发展中的投入冗余和产出不足,最后提出提高循环经济发展效率的改革路径。
Circular economy is a complex economic system with multiple inputs and prolific outputs. The objective and effective evaluation system of circular economy efficiency is the key to reflect the development of circular economy. According to the 3R principle of circular economy, this paper constructs an index system to evaluate the efficiency of circular economy in all provinces and municipalities in western China. The dynamic DEA model is used to evaluate the efficiency of circular economy in all provinces and municipalities in western China. This paper analyzes the data of the 11 provinces and municipalities in the west of China in 2010 and analyzes the main factors that affect the efficiency of circular economy from the perspectives of input and output respectively. It points out the input redundancy and output shortages in the development of circular economy in non-DEA effective areas, Recycling economy development efficiency of the reform path.
