| 中文摘要 |
| 基于社会网络分析及回归分析方法，选取珠三角城市群2001~2019年地级市数据，考察珠三角城市群碳排放空间关联网络特征的减排效应.结果表明：①珠三角城市群内各城市间的碳排放联系程度较为疏松，从属结构变动频繁，城市间的碳排放交流与合作亟待增强.②碳排放空间关联网络的中心-边缘结构产生一定程度的松动，中心城市对于整体网络结构的控制能力在减弱，边缘城市有逐渐由被控制向控制角色转变的趋势.③碳排放空间关联的整体网络紧密程度及稳定性的提升、网络等级结构的破除能显著降低地区碳排放量，而个体网络中心性的提高对于城市碳减排具有显著的促进作用.以上分析将有助于为协调二氧化碳减排和低碳城市发展政策的提出提供借鉴. |
| 英文摘要 |
| Based on social network and regression analyses, this study conducted research with regard to the spatial correlation and effect of carbon emissions in urban agglomerations of the Pearl River Delta (PRD) with the data of prefecture-level cities in Pearl River Delta urban agglomerations from 2001 to 2019. As the results suggested, ① the carbon emission links among cities in PRD urban agglomerations were relatively loose, the subordinate structure changed frequently, and the carbon emission exchanges and cooperation among cities need to be strengthened. ② The core-periphery structure of the spatial correlation network of carbon emissions was loose to a certain extent, the control ability of the central city to the overall network structure was weakened, and the marginal cities gradually changed from being controlled to adopting a controlling role. ③ The improvement in the overall network tightness and stability and the breaking of the network hierarchical structure significantly reduced regional carbon emissions, whereas the improvement in individual network centrality significantly promoted urban carbon emission reduction. The above analysis will help to provide reference for coordinating carbon dioxide emission reduction and low-carbon city development policies. |
