Global cities act as influential hubs in the networked world. Their city brands, which are projected by the global news media, are becoming sustainable resources in various global competitions and cooperations. This study adopts the research paradigm of computational social science to assess and compare the city brand attention, positivity, and influence of ten Globalization and World Cities Research Network (GaWC) Alpha+ global cities, along with their dimensional structures, based on combining the cognitive and affective theoretical perspectives on the frameworks of the Anholt global city brand dimension system, the big data of global news knowledge graph in Google’s Global Database of Events, Language, and Tone (GDELT), and the technologies of word-embedding semantic mining and clustering analysis. The empirical results show that the overall values and dimensional structures of city brand influence of global cities form distinct levels and clusters, respectively. Although global cities share a common structural characteristic of city brand influence of the dimensions of presence and potential being most prominent, Western and Eastern global cities differentiate in the clustering of dimensional structures of city brand attention, positivity, and influence. City brand attention is more important than city brand positivity in improving the city brand influence of global cities. The preferences of the global news media over global city brands fits the nature of global cities.

全球城市的城市品牌影响力比较:基于词嵌入的语义挖掘与GDELT全球新闻知识图谱大数据聚类分析

全球城市是网络世界中具有影响力的枢纽。他们的城市品牌被全球新闻媒体所投射,正在成为各种全球竞争与合作中的可持续资源。本研究采用计算社会科学的研究范式,基于认知与分析相结合,评估和比较十个全球化与世界城市研究网络(GaWC)Alpha+全球城市的城市品牌关注度、积极性和影响力及其维度结构。 Anholt全球城市品牌维度体系框架、谷歌全球事件、语言和语气数据库(GDELT)中全球新闻知识图谱大数据、词嵌入语义挖掘和聚类分析技术的情感理论视角. 实证结果表明,全球城市的城市品牌影响力的整体价值和维度结构分别形成了不同的层次和集群。尽管全球城市具有共同的城市品牌影响力结构特征,即存在性和潜力维度最为突出,但东西方全球城市在城市品牌关注度、积极性和影响力维度结构的聚集上存在差异。在提升全球城市的城市品牌影响力方面,城市品牌关注度比城市品牌积极度更重要。全球新闻媒体对全球城市品牌的偏好符合全球城市的性质。尽管全球城市具有共同的城市品牌影响力结构特征,即存在性和潜力维度最为突出,但东西方全球城市在城市品牌关注度、积极性和影响力维度结构的聚集上存在差异。在提升全球城市的城市品牌影响力方面,城市品牌关注度比城市品牌积极度更重要。全球新闻媒体对全球城市品牌的偏好符合全球城市的性质。尽管全球城市具有共同的城市品牌影响力结构特征,即存在性和潜力维度最为突出,但东西方全球城市在城市品牌关注度、积极性和影响力维度结构的聚集上存在差异。在提升全球城市的城市品牌影响力方面,城市品牌关注度比城市品牌积极度更重要。全球新闻媒体对全球城市品牌的偏好符合全球城市的性质。在提升全球城市的城市品牌影响力方面,城市品牌关注度比城市品牌积极度更重要。全球新闻媒体对全球城市品牌的偏好符合全球城市的性质。在提升全球城市的城市品牌影响力方面,城市品牌关注度比城市品牌积极度更重要。全球新闻媒体对全球城市品牌的偏好符合全球城市的性质。
