Abstract

According to the characteristics of the circular economy conception of the under-development regions under new economy situation, the improved data envelopment analysis model based on geometric mean model is reconstructed in the paper through increasing unexpected input (waste recycling quantity) in the input and increasing unexpected output (waste discharge quantity) in the output; then, the improved data envelopment analysis model is adopted to evaluate the efficiency of the circular economy of the under-development regions in 31 provinces and cities in China during 2002-2012. The research result shows that the efficiency of the circular economy of the under-development regions in China is generally improved, and the scale efficiency gradually tends to reach the optimum efficiency, but the obvious insufficiency of pure technical efficiency has influenced the development level of the circular economy of the under-development regions in China.

基于几何平均模型的改进数据包络分析模型

根据新经济形势下欠发达地区循环经济概念的特点，通过在投入中增加意外投入(废物回收量)，在产出中增加意外产出(废物排放量)，重构了改进的基于几何平均模型的数据包络分析模型;然后，采用改进的数据包络分析模型对2002-2012年中国31个省市欠发达地区的循环经济效率进行了评价。研究结果表明，中国欠发达地区循环经济效率总体上有所提高，规模效率逐渐趋向于最优效率，但纯技术效率的明显不足影响了中国欠发达地区循环经济的发展水平。
