理解数字时代信息扩散需要应对日益增长的社会动态性和复杂性。本研究提出“观念流”分析视角，通过挖掘信息中承载的情绪、集体观和偏见等三种观念，揭示平台观念流动的复杂图景。从平台层面看，三种观念随时间变化构成一个不同速率的多重流动体系。从平台到用户的观念流动看，平台推送的观念虽受外部事件影响不断波动，但用户间的观念差异并未持续扩大、缩小抑或变得混乱，而是呈现“同频共振”的模式。上述发现揭示了信息扩散背后社会事实、平台和用户间的复杂互动机制。观念流对社会复杂动态变化的敏感性和灵活性使其有潜力广泛应用于数字社会的重要研究议题。

Understanding the information diffusion in the digital age needs to deal with the increasing social dynamics and complexity. This article proposes an analytical perspective "Concept Flows" and reveals the complex landscape of concept flow within digital platforms by mining the emotions, collective views, and biases embedded in information. In the aspect of platform,the three concepts constitute a multiplicity of flows with varying rates over time. In the aspect of concept flow from platform to users, despite the fluctuations of concepts pushed by the platform due to external events, the concept differences between users do not increasingly diverge, converge, or become chaotic. Instead, they exhibit a "sympathetic resonance effect". These findings reveal the complex interaction mechanisms among social facts, platforms, and users behind information diffusion. The Concept Flows perspective's sensitivity and flexibility in capturing complex social dynamic changes suggest its potential application in broader important agendas about digital society.
