Diffusion channels are critical to determining the adoption scale, which leads to the ultimate impact of an innovation. The aim of this study is to develop an integrative understanding of the impact of two diffusion channels (i.e., broadcasting vs. virality) on innovation adoption. Using citations of a series of classic algorithms and the time series of co‐authorship as the footprints of their diffusion trajectories, we propose a novel method to analyze the intertwining relationships between broadcasting and virality in the innovation diffusion process. Our findings show that broadcasting and virality have similar diffusion power, but play different roles across diffusion stages. Broadcasting is more powerful in the early stages but may be gradually caught up or even surpassed by virality in the later period. Meanwhile, diffusion speed in virality is significantly faster than broadcasting and members from virality channels tend to adopt the same innovation repetitively.

创新采用：广播与病毒式传播

扩散渠道对于确定采用规模至关重要，这将导致创新的最终影响。这项研究的目的是发展对两个传播渠道（即广播与病毒性传播）对创新采用的影响的综合理解。利用一系列经典算法的引用以及合著者的时间序列作为其扩散轨迹的足迹，我们提出了一种新颖的方法来分析创新扩散过程中广播与病毒性之间的相互联系。我们的发现表明，广播和病毒传播具有相似的扩散能力，但在各个扩散阶段起着不同的作用。广播在早期阶段功能更强大，但在后期可能会逐渐被病毒传播赶上，甚至被病毒传播所超越。同时，
