| 中文摘要 |
| 厘清新型城镇化与城镇居民生活能耗低碳化之间耦合协调关系的动态及机制,可从城镇化视角为国家的低碳经济等高质量发展战略提供基础数据和理论支撑. 综合利用熵值法、耦合协调度模型、核密度估计以及障碍度模型等,探究2005~2021年中国新型城镇化与城镇居民生活能耗低碳化两个系统的时空特征、耦合协调度以及障碍因子. 结果表明：①新型城镇化和城镇居民生活能耗低碳化两个系统的发展水平均呈上升趋势,且都具有较为明显的空间分异特征. ②新型城镇化和城镇居民生活能耗低碳化的耦合协调度上升态势明显,由2005年的0.553波动增长至2021年的0.714. 耦合协调度整体空间格局上具有较强的正相关性且空间关联性有所增强,局部空间结构及局部空间依赖方向的波动性较弱,并存在一定的路径依赖特征. ③经济城镇化是新型城镇化系统准则层中障碍度最大的维度,平均障碍度达34.77%；建成区面积占比是该系统中障碍度最大的指标,平均障碍度为23.48%. 城镇居民生活能耗低碳化系统中单位能源消耗碳排放量指标的障碍作用最强,障碍度均值为29.13%,碳排放密度指标的障碍作用最弱,障碍度均值为3.34%. 因此,建议各省份因地制宜构建发展方案,建立跨区域和多维度的协同合作机制,有序推动新型城镇化建设,促进“双碳”目标实现. |

| Clarifying the dynamics and mechanism of the coupling and coordination relationship between new-type urbanization and the low-carbonization of the living energy consumption of urban residents can provide basic data and theoretical support for the national low-carbon economy and other high-quality development strategies from the perspective of urbanization. The entropy method, coupling coordination model, kernel density estimation, and obstacle model were used to investigate the spatial and temporal characteristics, coupling coordination, and obstacle factors of the two systems of China's new-type urbanization and the low-carbonization of the living energy consumption of urban residents from 2005 to 2021. The results showed that： ① The overall level of new-type urbanization and low-carbonization of the living energy consumption of urban residents showed an upward trend, and both had obvious spatial differentiation characteristics. ② The coupling coordination degree of new-type urbanization and the low-carbonization of the living energy consumption of urban residents showed a clear upward trend, increasing from 0.553 in 2005 to 0.714 in 2021. The overall spatial pattern of the coupling coordination degree exhibited a strong positive correlation, spatial correlation was enhanced, local spatial structure and dependence of the direction of the fluctuation were weak, and certain path dependent characteristics were observed. ③ Economic urbanization was the dimension with the biggest obstacle in the guideline layer of the new-type urbanization system, with an average obstacle degree of 34.77%； the built-up area ratio was the indicator with the biggest obstacle degree in the system, with an average obstacle degree of 23.48%. In the system of low-carbonization of the living energy consumption of urban residents, the indicator of carbon emission per unit of energy consumption had the strongest barrier effect, with an average barrier degree of 29.13%, whereas the indicator of carbon emission density had the weakest barrier effect, with an average barrier degree of 3.34%. Therefore, each province is recommended to construct development plans according to local conditions, establish a cross-regional and multi-dimensional synergy and cooperation mechanism, and promote the construction of new-type urbanization in an orderly manner, to facilitate the realization of the “dual-carbon” goal. |
