摘要
选取中国大陆地区的289个地级以上城市为研究对象,采集各城市百度指数数据,运用图表判别法和聚类分析法,判别中国城市体系等级结构,得到全国性中心城市3个、区域性中心城市13个、省域性中心城市22个和地方性中心城市251个.结果表明:信息网络下中国城市的等级体系金字塔结构明显;城市等级受社会经济、旅游文化和热点事件影响显著;高等级城市的数量分布呈"东密西疏、南密北疏"的分布状态,并与城市群等级分布格局吻合.
289 prefecture-level and above cities in China's Mainland were selected as the research object,and Baidu index data of each city was collected.Graphical discriminant analysis and cluster analysis were used to discriminate the hierarchical structure of China’s urban system.3 national central cities,13 regional center cities,22 provincial center cities and 251 local center cities were celected.This research showed that the hierarchical pyramid pyramid structure of Chinese cities under the information network was already obvious;the rank of cities was significantly affected by social economy,tourism culture and hot events;the distribution of high-grade cities was presented of a“Eastern and southern dense,Western and northern sparse”state,which was consistented with the distribution pattern of urban groups.
