| 在城市建筑碳排放持续增长的背景下，利用城市间的网络关系实现协同减排至关重要. 基于改进引力模型和社会网络分析探讨了长三角城市群建筑碳排放空间关联网络的结构特征及其协同效应. 结果显示，网络呈现出“核心-边缘”结构，网络关系数逐年增加，网络协同性增强；上海、苏州和无锡处于网络的领导地位，南通和马鞍山是接近中心度最高的城市，南京连接关系最丰富；长三角城市群分为4个板块，净受益板块多为经济发达城市，集中在沿海区域，净溢出板块的城市资源丰富，经纪人板块负责城市间的信息传递，双向溢出板块加速网络关系的流动. 研究结果有助于理清各城市的协同角色定位，为制定城市群协同减排策略提供参考. |
| 英文摘要 |
| Against the backdrop of continuous growth in urban building carbon emissions， it is crucial to utilize inter-city network relationships to achieve synergistic emission reduction. Based on the improved gravity model and social network analysis， the structural characteristics of the spatial network of building carbon emissions in the Yangtze River Delta city （YRD） agglomeration and its synergistic effect were explored. The results showed that the network had a “core-edge” structure， with an increasing number of network relationships and network synergy. Shanghai， Suzhou， and Wuxi were in the leading position of the network； Nantong and Maanshan were the cities with the highest closeness centrality； whereas， Nanjing had the richest connectivity. The YRD city cluster was divided into four plates， and the net beneficiary plate included economically developed cities， concentrated in the coastal region. The net spillover plate was rich in city resources， and the broker plate was responsible for information transfer between cities. The bidirectional spillover plate accelerated the flow of network relationships. The results of the study helps clarify the synergistic role positioning of the cities and provide a reference for the development of synergistic emission reduction strategies for city clusters. |
