With the rapid development of China, urbanization has become an important research topic of China's CO emissions. To fill the gap in considering the spatial correlation of the comprehensive urbanization that includes multi-dimensional factors on CO emissions from urban civil buildings (UBEC), this study constructs a comprehensive evaluation indicator of urbanization from four aspects including population, economy, society, and land urbanization by using the entropy method. The spatial spillover effect of UBEC and the impact of comprehensive urbanization on UBEC are also studied by using the spatial panel model in this paper. This study finds out that UBEC has obvious spatial spillover effects. During the early years of the study period, the eastern coastal areas had greater carbon emissions, while in recent years, they have gradually transitioned to the northwestern regions. Comprehensive urbanization has a significant promotion effect on it. And foreign direct investment and per capita energy consumption also have positive impact on UBEC. This study provides a reference for measuring the effects of urbanization on sector-specific CO emissions and may be useful for energy efficiency and emission abatement efforts in China.
随着中国的快速发展，城市化已成为中国 CO2 排放的一个重要研究课题。为了填补考虑包含多维度因素的综合城市化对城市民用建筑 CO2 排放（UBEC）的空间相关性的空白，本研究利用熵值法从人口、经济、社会和土地城市化四个方面构建了城市化的综合评价指标。本文还利用空间面板模型研究了 UBEC 的空间溢出效应以及综合城市化对 UBEC 的影响。研究发现，UBEC 具有明显的空间溢出效应。在研究初期，东部沿海地区的碳排放较多，而近年来，碳排放逐渐向西北地区转移。综合城市化对其有显著的促进作用。此外，外商直接投资和人均能源消费对 UBEC 也有正向影响。本研究为衡量城市化对特定部门 CO2 排放的影响提供了参考，可能有助于中国提高能源效率和减排努力。
