摘要
微信公众号文章可用于量化城市关注度等级与联系。通过文本挖掘方法计算我国657个县级及以上城市的关注度、联系度、隶属度等指标,分析城市关注度等级及联系网络体系。结果显示:城市关注度符合位序一规模分布;城市联系总体呈现钻石型空间结构,城市群內部联系表现出集中型和均匀型两种结构特征;城市隶属关系以省份内部为主,呈现岀单核心和多核心两种结构特征。最后,讨论了微信数据在城市硏究中的应用价值以及对城市地位提升的作用。
The urban hierarchy of attention degree and the relationship of cities can now be explored and quantified by using WeChat articles.By applying text mining technology this paper calculated indices such as urban attention degree,relationship degree and subordinate degree of 657 cities above county level to analyze the spatial pattern of city's attention degree and its relationship network in China.The results show as follows.First,the attention degree corresponds to the rank-size distribution.Second,the spatial pattern of city relationship shows a diamond-shaped structure.The relationship pattern inside the urban agglomeration shows two kinds of features,centralized and non-centralized.Third,most of the subordinate relationships are inside province and the spatial pattern shows either single or multi kernel.Last,it discusses WeChat articles'application value to urban research and its promoting function to city level.
