Abstract:

With the penetration of digital technology in daily life, residents' ability of digital representation of the city is gradually enhanced. At the same time, the concept of community has been reshaped by the Internet. As a kind of digital city platform, the online community's characterization and reshaping of city space has attracted the attention of scholars at home and abroad. Based on the data from the Post Bar of Chinese City, this study adopted ethnography, content analysis, and spatial analysis to deeply analyze the characteristics of the user-generated content of the online community and its characterization and reshaping of the city hierarchy. The following conclusions are drawn. ①Community users' attention to the city is affected by the reality of urban social and economic development. There is a significant difference between the southeast and the northwest separated by the Hu Huanyong line. Chengdu is the core city of the Post Bar of Chinese City. This reflects that although the attention of cities in cyberspace is highly influenced by users' subjectivity, it is also based on the projection and reflection of the physical space mapped to the virtual world; ②The image of the Post Bar of Chinese City is mainly blue, orange and green in color distribution, corresponding to the visual images of the city in science and technology and economy, cultural tourism and civic life, as well as artificial and natural, showing the visual interpretation of the city image by the community users; ③Community users are mainly based on the four evaluation dimensions of urban economy, population, urban construction level and built-up area. The user-generated content of the Post Bar of Chinese City has built a city hierarchy with Shanghai, Chengdu and Beijing as first-tier cities. The research results enrich the existing research results of the online community, and provide reference for the Internet application and public opinion guidance in the process of local image building and local marketing of Chinese cities.

摘要：

在线社区作为一类数字城市平台，对城市空间的表征与重塑得到了国内外学者的密切关注。研究以百度贴吧的“中华城市吧”社区为例，结合网络民族志与内容分析法进行数据收集与内容挖掘，深入分析在线社区用户生成内容的特征及其对城市等级体系的表征与重塑。结果表明：①社区用户对于城市的关注受到城市社会经济发展现实情况的影响，以胡焕庸线为分隔的“东南-西北”差异明显，成都是“中华城市吧”社区的核心关注城市；②“中华城市吧”社区的图像库在色调分布上以蓝色、橙色和绿色为主，对应了城市在科技与经济、文旅与市民生活以及人工与自然等方面的视觉形象，显示出社区用户对于城市形象的可视化解读；③社区用户主要基于城市经济实力、人口情况、城建水平、建成区面积4个评价维度，构建了以上海、成都、北京为一级城市的城市等级体系。研究结论丰富了现有在线社区的地理研究成果，同时为中国城市的地方形象塑造和地方营销等过程中的互联网应用与舆论引导提供参考。
