| 中文摘要 |
| 建筑业作为长三角地区碳排放的主要来源之一,其碳脱钩水平及其空间关联直接影响地区“双碳”目标的实现进程. 基于2009~2023年长三角41个城市建筑业碳排放数据,采用修正引力模型和社会网络分析,构建碳脱钩空间关联网络,结合最优参数地理探测器,探究其内在结构及驱动因素. 结果表明:①长三角建筑业碳脱钩关联网络呈现“去中心化”特征,整体网络关联度和网络密度提升,高水平网络效率值反映网络结构的潜在脆弱性,上海和省会城市等传统核心节点的辐射能力相对弱化,安徽省部分城市的碳脱钩中间中心度提升明显. ②网络存在分工明确的异质性板块,少部分省会城市等经济发达地区位于“净溢出”板块,对外辐射效应突出,“净受益”板块由安徽省大部分城市构成,成为外部溢出的主要吸纳区,“双向溢出”板块由浙江省众多城市构成,内外互动显著,江苏省部分城市形成“经纪人”板块,中介作用明显. ③最优参数地理探测器分析结果表明,基于交互探测的非线性增强效应占主导地位,能源结构与技术创新的协同作用最为突出,环境规制与数字金融的联动效应形成梯度传导机制,数字基建与金融科技的融合构建了全生命周期碳管控体系. |

| As the main source of carbon emissions in the Yangtze River Delta, the level of carbon decoupling and its spatial correlation characteristics in the construction industry directly affect the progress of achieving the region's “dual carbon” goals. Based on the carbon emissions data of the construction industry in 41 cities in the Yangtze River Delta from 2009 to 2023, a modified gravity model and social network analysis method were used to construct a carbon decoupling spatial correlation network. Combined with the optimal parameter geographic detector, the internal structure and driving factors were explored. The results show that: ① The carbon decoupling network of the construction industry in the Yangtze River Delta presented a “decentralized” feature, with an overall increase in network connectivity and density. The high-level network efficiency value reflected the potential vulnerability of the network structure, and the radiation ability of traditional core nodes such as Shanghai and provincial capital cities was relatively weakened. The intermediate centrality of carbon decoupling in some cities in Anhui Province had significantly increased. ② There were heterogeneous sectors with a clear division of labor in the network. A small number of economically developed areas such as provincial capitals were located in the “net spillover” sector, with prominent external radiation effects. The “net benefit” sector was composed of most cities in Anhui Province, becoming the main absorption area for external spillover. The “two-way spillover” sector was composed of many cities in Zhejiang Province, with significant internal and external interactions. Some cities in Jiangsu Province have formed a "broker" sector, with a clear intermediary role. ③ The analysis results of the optimal parameter Geodetector indicated that the nonlinear enhancement effect based on interactive detection dominated, and the synergistic effect between energy structure and technological innovation was most prominent. The linkage effect between environmental regulation and digital finance formed a gradient transmission mechanism, and the integration of digital infrastructure and financial technology constructed a full lifecycle carbon control system. |
