| 摘要: |
| 在构建区域生态效率评价指标体系基础上,应用数据包络分析( DEA) 提出了区域生态效率时空分异评价方法,并对中国2000—2012 年30 个省市区生态效率时空分异情况进行测度分析。结果表明:2000—2012 年中国区域生态效率提升并不显著,且与经济增长高度一致;东部地区省市生态效率明显高于中西部地区,且时序提升明显,与中西部地区差距正在拉大,中西部地区差距在缩小,西部地区时序提升明显;中国区域生态效率前沿长期由江苏、山东、浙江、北京、广东等省市构成,两极分化加剧。 |

| Abstract: |
| A method and an indicator system are brought forward to evaluate the spatial-temporal differences of regional eco-efficiency (EE) based on DEA, and evaluate the spatial-temporal differences of EE among Chinese 30 provinces from 2000 to 2012. The results show that the average EE of China has been promoted slowly in the past 13 years, but not significantly, which is highly consistent with Chinese economic growth. And the eastern provinces that have significant temporal promotion, get obviously higher average EE than the mid-west provinces, and the efficiency gap is enlarging. Meanwhile, the efficiency gap between the middle and west provinces is narrowing because of the significant temporal promotion in the west provinces. The EE frontier of China is composed by such provinces as Jiangsu, Shandong, Zhejiang, Beijing, Guangdong, etc. which will lead to polarization. |
