Spatial cities of China in 2015
China’s administrative cities and spatial cities are mismatched and the administrative cities are much larger than their spatial regions. In the administrative boundary, Chinese cities compose both urbanization area and rural area，thus it if very important for redefining Chinese city system. We are sharing our identified spatial cities of China in 2015 using communities as basic administrative units and the data of urban built-up areas.
中国行政城市与空间城市不匹配，行政城市规模远远大于空间区域。在管理边界,中国城市构成城市化地区和农村地区,因此,重新定义中国城市系统非常重要。2015年，我们将社区作为基本管理单元，并结合城市建成区数据，共享我们确定的中国实体城市（spatial cities）。
