摘　　要：基于研究的时效性、非期望产出的影响以及循环经济的再循环特性,重构了城市循环经济的评价指标,以2011—2017年中国31个省、自治区及直辖市的数据作为研究对象,运用数据包络分析模型,对中国各省市的循环经济效率进行深入分析。研究结果表明:1)2011—2017年中国城市循环经济效率总体均值不高,分布极不均衡.2)2017年中国东部地区的循环经济技术效率最高,中部地区和西部地区的循环经济技术效率相等.3)2017年纯技术效率呈现东部最高,中部居中,西部最低的格局;西部地区的规模效率高于中部地区,而东部地区的规模效率最低.因此,降低固定资产投入,减少二氧化硫排放量以及增加一般工业固体废物综合利用率是中国城市循环经济效率改善的重要途径。Based on the timeliness of the study, the impact of unexpected output and the recycling characteristics of circular economy, this paper reconstructed the evaluation index of urban circular economy. Targeting the data of 31 provinces, autonomous regions and municipalities of China from 2011 to 2017, this paper employed the data envelopment analysis model to analyze the efficiency of circular economy in China s provinces and municipalities. The results show that: 1) From 2011 to 2017, the average efficiency of circular economy in China s cities was not high, with extremely uneven distribution;2) In 2017, the technical efficiency of circular economy in eastern China was the highest, while the technical efficiency in central China was equal to that in western China. 3) In 2017, it was shown that pure technical efficiency was the highest in eastern China, the middle in central China and the lowest in western China;the scale efficiency of western China was higher than that of central China, while the scale efficiency of eastern China was the lowest. In short, they were important ways to improve the efficiency of circular economy in Chinese cities in 2017 by reducing investment in fixed assets, reducing sulfur dioxide emissions and increasing the comprehensive utilization rate of general industrial solid waste.
