Online-to-offline (O2O) e-commerce has profoundly impacted the space of the urban hotel industry. Drawing on insights from flow space and central flow theory, this study establishes an electronic word of mouth (E-WoM) index system of hotels in Nanjing by using Dianping.com data and analyses the hotel central place hierarchy based on the consumption price and E-WoM score. The central place hierarchy based on the consumption price presents a core-edge hierarchical structure that conforms to central place theory, while that based on the E-WoM score presents a flat, multicentre network structure that conforms to central flow theory. This result not only shows the geographically rooted influence on cyberspace but also reflects the spatial mismatch between the service level and online volume level. Impacted by E-WoM information flow, a new spatial pattern of the virtual hotel industry based on cyberspace is formed, which may reshape the central place hierarchy of the traditional hotel industry.

线上到线下（O2O）电子商务已经深刻影响了城市酒店业的空间。本研究借鉴流量空间和中心流理论，利用大众点评数据建立南京酒店电子口碑（E-WoM）指标体系，并基于消费价格和E对酒店中心地层级进行分析。 -WoM 分数。基于消费价格的中心地层级呈现出符合中心地理论的核心-边缘层级结构，而基于E-WoM评分的中心地层则呈现出扁平的多中心网络结构，符合中心流理论。这一结果不仅显示了对网络空间的地理根源影响，还反映了服务水平和在线量水平之间的空间不匹配。受电子口碑信息流的影响，
