摘要:提高生态效率是推进生态文明建设和绿色发展的重要途径。基于2003-2016年中原城市群29个城市的面板数据，运用Super-SBM （超效率SBM模型，Super slacks-based model）模型对生态效率进行测算，并综合运用GIS技术与空间滞后模型，分析了生态效率的时空演变及空间关联特征，研究了生态效率变动的影响因素。结果表明：（1）2003-2016年，中原城市群生态效率总体上呈"阶梯状"的上升趋势，空间分布存在差异，形成了北部和南部高，中间低的空间格局。（2）中原城市群生态效率呈正向空间自相关，空间集聚趋势逐步增强，冷点区在西北部地区动态变化，东南部地区形成稳定的热点区。（3）中原城市群生态效率存在正向空间溢出效应，经济发展水平和对外开放水平产生显著正向效应，而科技水平产生显著负向效应。



Abstract:Improving eco-efficiency is an important way to promote ecological civilization and green development. Taking the Central Plains Urban Agglomeration as the research object, this paper firstly used Super-SBM model to calculate the eco-efficiency of 29 cities from 2003 to 2016, used GIS technology to depict the spatio-temporal evolution and spatial correlation characteristics of eco-efficiency, then analyzed the influencing factors of eco-efficiency by using spatial lag model. The results showed that: (1) The eco-efficiency of the Central Plains Urban Agglomeration presented an overall stepped trend from 2003 to 2016. There were differences among regions with a pattern of high in the north and south but low in the middle. (2) The eco-efficiency of the Central Plains Urban Agglomeration showed the significantly positive spatial autocorrelation and the degree of spatial agglomeration gradually increased. The cold spots changed dynamically in the northwest and the southeastern parts formed stable hot spots. (3) There was a significant spillover effect of eco-efficiency, a significantly positive effect on the level of economic development and the level of openness, while a significantly negative effect on the level of science and technology.
