摘要
依据城市循环经济的内涵和特点,构建了城市循环经济效率评价指标体系.利用主成分分析和数据包络分析的原理,提出了基于PCA-DEA的城市循环经济效率复合评价模型.利用该模型对2010年河南省17个城市的循环经济发展效率进行了评估.结果表明,洛阳、安阳、新乡、焦作等4个城市的循环经济是DEA无效,并给出了这些城市改进的比例.
An evaluation index system for efficiency of city＇s circular economy was constructed by analyzing the city circular economy＇s characteristic and connotation. Based on theory of data envelopment analysis （DEA） and principal component analysis （PCA）, a combined PCA-DEA efficiency of city circular economy evaluation model was proposed. By using PCA-DEA model, the efficiency evaluation of 17 cities＇ circular economy was evaluated. The results show that circular economies of Luoyang, Anyang, Xinxiang, Jiaozuo were invalid DEA. And the proportion of improvement was given.
