本文联系新媒体与社会运动领域的相关研究文献,聚焦微信在华人声援梁彼得大游行中的信息传播和行动动员作用。本文提出,微信打破了公共与私人的界限,使得很多本没有强烈参与意愿的人在无意识的情况下参与了信息的传播,从而超越了集体行动的困境。此外,微信降低了创造和组织集体行动的成本,并塑造了集体认同。但是,微信并未取代以同乡会为代表的传统动员方式,也无法代替西方主流社交媒体。 This article links relevant research literature in the field of new media and social movements and focuses on the information dissemination and mobilization of WeChat in the Chinese solidarity with Leipzig Parade. This article proposes that WeChat breaks the boundary between public and private and makes many people who have no strong willingness to participate unconsciously to participate in the dissemination of information, thus exceeding the plight of collective action. In addition, WeChat reduces the costs of creating and organizing collective actions and shapes collective identities. However, weChat does not replace the traditional mobilization mode represented by fellow associations and can not replace the mainstream Western social media.
