黄河流域作为“能源流域”，粗放型发展模式和对高碳产业的依赖使近年来的碳排放量超过全国总量的1/3^[1] ，亟须加快向绿色高质量发展转变。积极稳妥推进碳达峰碳中和，关键在于通过技术创新提高能源利用效率、降低碳排放强度[2]。绿色技术创新作为绿色创新的核心[3]，涵盖了循环型创新[4-5]的关键环节，能够促进经济发展与生态环境保护协调，对“双碳”目标的实现有重要的支撑作用。为此，科技部等九部门共同研究制定了《科技支撑碳达峰碳中和实施方案(2022—2030年)》。然而，绿色技术创新高度集中在少数发达地区，欠发达地区则面临着“技术红利瓶颈”困境，制约着绿色技术创新的空间溢出效应。本文探讨了黄河流域城市绿色技术创新对碳排放强度的影响及其空间溢出效应，以期为推进黄河流域生态保护和经济绿色低碳转型高质量发展提供参考。

1文献综述

国内外学者针对绿色技术创新与碳减排开展了广泛研究。在绿色技术创新方面，主要围绕衡量方式、时空演变特征和影响因素等开展研究[6-7]。绿色技术创新有显著的空间集聚特征和周期性波动，绿色技术扩散与贸易活动有关，扩散路径主要是由高创新水平国家和地区向其他区域扩散。在碳排……
