摘　　要：提升城市生态效率水平是建设美丽中国、加快经济社会发展全面绿色转型的关键抓手和重要支撑。基于中国2003—2022年283个城市的面板数据,考察城市生态效率提升的同群效应和作用机制。研究表明,在地理、行政和经济权重距离影响下城市之间生态效率存在正向显著的同群效应,而且地理和经济距离邻近的城市具有较高的同群效应。高、中、低生态效率水平的城市之间同群效应具有显著的差异性,而且生态效率水平较高的城市更容易被其他城市学习和模仿。从作用机制来看,竞争性模仿机制和外部冲击因素均对同群效应产生促进效应,然而在学习性模仿机制中自我学习效应和示范学习效应均会对同群效应产生弱化影响。Improving the level of urban eco-efficiency is a key lever and important support for building a beautiful China and accelerating the comprehensive green transformation of economic and social development.Based on panel data of 283 cities in China from 2003 to 2022,this research examines the same group effect and mechanism of urban eco-efficiency improvement.The study shows that there are significant positive peer effects on eco-efficiency among cities under the influence of geographical,administrative,and economic weight distances,and cities adjacent to geographical and economic distances have higher peer effects.There are significant differences in the peer effects among cities with high,medium,and low eco-efficiency levels,and cities with higher eco-efficiency levels are more likely to become objects of learning and imitating the same group effect.From the perspective of mechanism,both competitive imitation mechanism and external impact factors have a promoting effect on the same group effect,while self-learning effect and demonstrative learning effect in learning imitation mechanism will weaken the peer effects.
