Social media provide new opportunities for supporting the dynamics of collective action (CA), allowing for the mobilisation of people into debates and involving them in new forms of collective decision making. Although current studies focus on opportunities offered by social media for collective action, there is still a need to deepen the understanding of how social media support the organisation of CA and to study the effects of individual actions performed on social media in complex organisational settings. We here explore how social media are used to manage CA by the Italian political movement Movimento Cinque Stelle, using the concept of affordances as the conceptual framing. Based on the qualitative case analyses, our study contributes to the knowledge base by identifying a typology of nine affordances supporting CA and exploring how the combined actualisations of some affordances of the typology create antecedents of the fundamental processes of CA. On the basis of the study analysis, we suggest a model to describe how social media support CA through affordances, their combinations, and the creation of antecedents and then formulate implications for research and practice.

结合社交媒体可供性组织集体行动

社交媒体为支持集体行动 (CA) 的动力提供了新的机会，允许动员人们参与辩论并让他们参与新形式的集体决策。尽管当前的研究侧重于社交媒体为集体行动提供的机会，但仍需要加深对社交媒体如何支持 CA 组织的理解，并研究在复杂组织环境中在社交媒体上执行的个人行为的影响。我们在这里探讨了意大利政治运动 Movimento Cinque Stelle 如何使用社交媒体来管理 CA，使用可供性的概念作为概念框架。基于定性案例分析，我们的研究通过确定支持 CA 的九种可供性的类型学并探索类型学的某些可供性的组合实现如何创建 CA 基本过程的前因，从而为知识库做出贡献。在研究分析的基础上，我们提出了一个模型来描述社交媒体如何通过可供性、它们的组合和前因的创造来支持 CA，然后制定对研究和实践的影响。
