Prior research is limited in how live-streaming platforms (LSPs) enable technological features facilitating political persuasion and engagement. Through the theoretical lens of affordance and theory of persuasion and mindfulness, this study (1) identifies persuasion-related affordances on LSPs that afford users with sufficient ability and motivation to process persuasive messages in live streaming, and (2) discovers how the actualization of such affordances fosters political mindfulness and promotes political engagement. We validate the research model using survey data collected from 16 live-streaming campaign rallies for the 2020 presidential election. This study makes significant theoretical contributions to live streaming and e-politics.

先前的研究仅限于直播平台 (LSP) 如何启用促进政治说服和参与的技术功能。通过可供性和说服与正念理论的理论视角，本研究 (1) 确定 LSP 上与说服相关的可供性，为用户提供足够的能力和动机来处理实时流媒体中的说服性消息，以及 (2) 发现如何实现这种可供性可以培养政治意识并促进政治参与。我们使用从 2020 年总统大选的 16 场直播竞选集会中收集的调查数据来验证研究模型。这项研究对直播和电子政治做出了重要的理论贡献。
