网络社区既是网络民族主义的动员场所，又是发生场所，与互联网时代粉丝社群的运 作逻辑不谋而合。本文通过分析新浪微博“饭圈女孩出征”网络爬虫数据，探讨该事件的 发展逻辑及扩散特征。研究发现，“饭圈女孩出征”是粉丝群体自发生成的、低组织化的 网络行动，但粉丝群体的动员能力与扩散作用却被高估，他们在整个事件中只起到了“讨 论酶”的作用，真正起到关键扩散作用的是传统媒体的网络账号。传统媒体官方账号的示 范效应降低了普通用户的参与门槛，其后在娱乐营销号及不同领域意见领袖的带动下，共 同促进该事件的深层扩散。通过社会网络分析发现，网络主体为紧密型的共意型扩散网 络，其扩散链条较短；少数“异见”网络则呈现较长的扩散链条。

 Nationalism campaigns are often aroused in online communities who also provide the avenue for the activists to march on. This phenomenon coincides with the operation mode of fandom groups in the internet era. This study investigated the development and spread of the “Fandom Girls Campaigns”, which were fan groups’ voluntary online actions without sophisticated organization,by crawling and analyzing related data obtained from Sina Weibo. The results suggested that the capability of fan groups to motivate and to spread was overestimated. The key influencers were traditional media with online accounts. The official online accounts of traditional media had demonstration effects on regular users and motivate them to participate. Later on, opinion leaders from different fields contributed to the deep spread of the event. Through social network analysis, we found that the main body of the spread was the consensus spread network with short spread chains; meanwhile, a few of the dissent network had longer spread chains.
