摘　　要：绿色经济效率(GEE)提升是经济绿色、高质量发展的“助推剂”。该研究基于UndesirableSBM模型测度2007-2017年我国大陆30个省份的GEE,利用空间自相关及冷热点分析法,探究GEE的时空演变特征,运用地理探测器模型进一步揭示其驱动力的空间异质性。结果表明:①GEE呈“U形尾波”的阶段性特征,整体上由“小差距高效率”向“大差距低效率”动态演进,区域间形成“东-中-西”阶梯式递减的分异格局,“分化”与“极化”现象日益加剧。②GEE存在显著的“倒U型”空间关联性,总体呈“东热西冷”的空间分异特征,“极化-涓滴”效应有所凸显。其中,GEE热点区范围逐渐扩大,呈现零星面状分布向沿海带状蔓延的演进格局,次冷点区范围有所缩小,而次热点区和冷点区变化微弱,空间格局基本稳定。③GEE提升的驱动力全局差异不突出,但局域尺度差异显著。东、中、西部GEE提升的核心驱动力分别是:东部为政府干预、对外开放水平和技术创新水平;中部为能源强度、教育投入和市场化水平;西部为人力资本、能源强度、城市规模、教育投入、技术创新水平、环境规制和互联网普及率。基于此,东、中、西部要因势而谋、因地制宜。东部需激活技术密集型地区的“长板优势”,发挥科技创新的“滚雪球效应”;中西部需挖掘资源禀赋,推进新能源发展,加大科技研发投入,优化配置教育资源;同时,要推进整体信息化建设,强化网络引领。Green Economic Efficiency(GEE)improvement is a‘booster’for green and quality economic development.Based on the Undesirable-SBM model,the GEE of 30 provinces in China's Mainland from 2007 to 2017 have been measured.Using spatial autocorrelation and cold and hot spot analysis methods,the spatial and temporal evolution of GEE has explored.The geographic detector model is productively used to expose the spatial heterogeneity of its driving force.The results show that:①GEE shows the phasic features of a‘U-shaped tail wave’from 2007 to 2017,and it changes from‘low-range strong effect’to‘high-range weak effect’dynamically,forming a regional differentiation pattern of‘east-middle-west’step-decreasing and intensifying the phenomenon of‘polarization’and‘differentiation’.②GEE has a significant‘inverted U-shaped’spatial correlation and general spatial differentiation pattern of‘hot east and cold west’,and the‘polarization-trickling’is prominent.Among them,the scope of GEE hotspots has gradually expanded,showing the evolutionary pattern of sporadic planar distribution spreading to coastal bands,and the scope of sub-coldspots has narrowed.However,the changes of sub-hotspots and cold spots are slight,and the spatial pattern is basically stable.③The global differences in driving forces for GEE improvement are not prominent,but the local scale differences are significant.The core driving forces for the promotion of GEE in the eastern,central,and western regions are:the eastern region includes government intervention,degree of opening up,and technological innovation level;the central region includes energy intensity,education input and marketization level;the western region includes human capital,energy intensity,city size,education investment,technological innovation level,environmental regulations and Internet penetration.Hence,the eastern,central and western regions should be adjusted to local conditions and benefits.The eastern region needs to activate the‘long-board advantage’
