中文摘要：

采用因子分析、聚类分析、ESDA等方法，探讨2011年和2014年中国77个智慧城市发展水平空间差异演变，分析影响智慧城市发展的主因子。研究表明：（1）影响智慧城市空间差异的主因子动态变化不大，主要是综合实力因子；（2）中国地级以上智慧城市的总体水平空间差异明显；（3）中国智慧城市的发展格局单极态势较明显、呈“梭”型结构；（4）智慧城市发展主要受到城市发展的内在需求、对原有资源禀赋的惯性依赖、政策影响及智慧文化，尤其是政策作用非常显著。

英文摘要：

The spatial difference of77Smart Cities is explored in China at2011and2014By factor analysis,cluster analysis,ESDA,etc,and the factors that influence the development of Smart City are analyzed.The research showsthat(1)The main factors that affect the spatial difference of the Smart Cityare not much of a change,and the main factors are comprehensive strength factors.(2)The overall difference level of Smart City is obvious in China.(3)Unipolar situation is more obvious in the development pattern of China's smartcity and has a"shuttle"structure.(4)The development of Smart City is mainlyinfluenced by the inherent requirement of the city,and the inertia dependenceand policy of the original resources endowment,and smart culture,andthe role of policy is peculiarly significant.
