| 中文摘要 |
| 以长三角地区为研究区域，在评估信息、企业和经济网络空间结构特征及全范围碳排放效率空间分布特征的基础上，深入探讨城市网络对碳排放效率的影响及作用机制，推动长三角地区如期实现“双碳”目标. 结果发现：①三者网络均显示城市间联系越来越密切，社区结构呈现多样化、小团体结构明显、跨区域性及变动性强的特征；整体碳排放效率有所提升，高值及较高值区向东迁移. ②城市网络影响力的提高可显著提升碳排放效率，同时受城市性质和数字发展水平差异影响，中心城市和低水平数字建设的城市网络碳减排效应更明显. ③城市网络通过信息溢出和企业协同途径对全范围碳排放效率产生正向提升作用，而经济合作模式仅能提升直接碳排放效率. |

| Taking the Yangtze River Delta （YRD） region as the study area， based on the assessment of the spatial structure characteristics of information， enterprise and economic networks， and the spatial distribution characteristics of the overall carbon emission efficiency， the impacts and mechanisms of the urban networks on carbon emission efficiency are explored in depth， so as to promote the YRD region to achieve the goal of ‘dual-carbon’ on schedule. The results showed that： ① All three networks showed that cities were becoming increasingly closely connected with each other， the community structure was diversified， the small group structure was obvious， and the trans-regional and changeable characteristics were strong. The overall carbon emission efficiency had been improved， and the high and higher value areas had moved to the east. ② The increase of city network influence could significantly improve the carbon emission efficiency， and affected by the difference of city nature and digital development level， the carbon emission reduction effect of the city network was more obvious in the central city and the city network with a low level of digital construction. ③ Urban networks could positively improve the efficiency of carbon emissions in the whole range through information spillover and enterprise collaboration， while the economic cooperation mode could only improve the efficiency of direct carbon emission. |
