中国循环经济运行效率的评估与空间差异性研究——基于DEA-ESDA的探索性分析

Estimation and Spatial Heterogeneity Research of Chinese Circular Economy Operational Efficiency

借助较为前沿的基于理想点决策单元的交叉效率DEA模型,对我国30个省份的循环经济运行效率进行评估,并在此基础上采用ESDA探索技术对全国30省份以及东、中和西部地区的循环经济运行效率的空间差异性进行探索。研究结果表明,我国循环经济运行效率较高的地区为浙江、北京、广东、福建、江西和上海地区;东、中和西部地区的循环经济运行效率存在差异,并且三大区域内部的差异也十分明显;我国循环经济的运行效率在整体上表现出十分显著的空间相关性。同时,东、中和西部地区的空间相关性亦存在明显的差异;我国循环经济的高值集聚区主要位于东部,而低值集聚均位于西部地区。同时,三大区域内部的集聚也表现出不同的模式。

With the advanced cross efficient model based on TOPSIS, this paper evaluates the operation efficiency of circular economy efficiency in China. And through using the ESDA method, the spatial heterogeneity of circular economy in China including eastern, central and western parts is explored. The research results show： the efficiency of Zhejiang, Beijing, Fujian, Jiangxi and Shanghai is higher than the other regions; not only significant differences of circular economy operational efficency exist between the east, central and west parts in China, but also exist in the inner region of these districts; the operational efficiency of circular economy in China presents characters of spatial correlation, significantly. While, in the east, central and west part, the spatial correlation of circular economy is quite different; the high value agglomeration of circular economy operational efficiency is mainly located in the eastern part of China, while the regions of low value agglomeration are mainly located in the westeren part of China. Meanwhile, the agglomeration of the three parts themselves also shows different patterens.
