| 创新驱动发展与“双碳”战略的历史交汇期，明晰黄河流域城市间碳中和技术创新的空间关系，对于推动黄河流域生态保护和高质量发展意义凸显. 基于对黄河流域77个地级市2010~2022年碳中和技术创新效率的有效测度，借助修正引力模型以及社会网络分析法对碳中和技术创新效率空间网络关联特征进行综合评估，开展β收敛分析以阐释其空间收敛规律. 结果表明，黄河流域碳中和技术创新效率呈现“下游>中游>上游”格局，局部动态性特征与不均衡特征并存；黄河流域内部碳中和技术创新效率网络密度呈现下游到中游再到上游逐级降低的态势；黄河流域下游沿海城市在其他板块的溢出效应下发展迅猛，郑州市、济南市和菏泽市等成为重要的中心城市辐射带动周边地区发展；空间收敛分析显示，黄河流域内各城市碳中和技术创新效率的收敛特征和追赶效应显著，且下游地区收敛速度最快. |

| At the historical intersection of innovation-driven development and the “two-carbon” strategy， clarifying the spatial relationship of carbon neutral technological innovation among cities in the Yellow River Basin is of great significance for promoting ecological protection and high-quality development in the Yellow River Basin. Based on the effective measurement of carbon neutral technology innovation efficiency of 77 prefecture-level cities in the Yellow River Basin from 2010 to 2022， this study comprehensively evaluates the spatial network correlation characteristics of carbon neutral technology innovation efficiency with the help of the modified gravity model and social network analysis and carries out β convergence analysis to explain its spatial convergence rule. The results showed that the carbon neutral technology innovation efficiency in the Yellow River Basin presented a pattern of “lower reaches > middle reaches > upper reaches”， with local dynamic characteristics and unbalanced characteristics co-existing. The network density of carbon neutral technology innovation efficiency in the Yellow River Basin gradually decreased from upstream to downstream and then to the middle reaches. The coastal cities in the lower reaches of the Yellow River Basin developed rapidly under the spillover effect of other plates. Zhengzhou， Jinan， and Heze have become important central cities to radiate and drive the development of the surrounding areas. The spatial convergence analysis showed that the convergence characteristics and catch-up effect of carbon neutral technological innovation efficiency in cities in the Yellow River Basin were significant， and the convergence speed was the fastest in the downstream area. |
