中文摘要：

本研究选择了中国52个主要城市，使用智慧低碳强度商数（SLSQ）这一创新量化模型探讨城市智慧低碳发展的水平和状态。研究结果表明：（1）智慧低碳城市可以分为三个主要类别，即具有高SLSQ的领导型，具有平均SLSQ的稳定发展型和具有低SLSQ的滞后发展型；（2）中国主要城市的SLSQ水平表现出较为明显的“从东南向西北递减，区域间存在差异”的空间变化趋势；（3）中国主要城市的SLSQ在城市规模上表现出“从大到小递减，规模内存在差异”的变化趋势；（4）中国主要城市的SLSQ水平在行政等级上表现出“从高向低递减，等级内存在差异”的变化趋势；（5）基于SLSQ水平，中国主要城市可以被划分为三个动态模式：领导模式，稳定模式和准备模式，其中稳定模式占绝大多数。

英文摘要：

This study chose major Chinese cities and used the creative model of Smart Low-carbon Strength Quo- tient （SLSQ） to investigate the level and state of urban smart low-carbon development. The results show that： （1） three main categories of smart low-carbon cities are found; namely, leaders with high SLSQ, steady ones with av- erage SLSQ and lagging ones with low SLSQ; （2） the SLSQ level shows a spatial change trend of diminishing from the southeast to the northwest and differing within regions; （3） the SLSQ level indicates an urban scale change trend of decreasing from the big to the small and differing within each scale; （4） the SLSQ level suggests an ad- ministrative hierarchy change trend of descending from the high to the low and differing within each class; （5） based on the SLSQ, three dynamic patterns were identified： leading mode, steady mode and preparing mode, among which the steady mode accounts for the vast majority of smart low-carbon development in major Chinese cities.
