我们研究了两个传播实体的竞争，例如创新，在复杂的网络中的复杂传染过程。我们开发了一个分析框架，并研究双重用户的作用，即代理使用这两种技术。寻找新的创新的传播过渡和灭绝过渡的一个预先存在的，我们确定不同的阶段取决于网络的平均程度，流行的预先存在的技术，和阈值的传染过程。与现有技术的竞争有效地抑制了新创新的传播，但它也允许共存的阶段。双重用户的存在在很大程度上改变了瞬态动态，创造了新的阶段，促进了新创新的传播和原有创新的消亡。它使新的创新能够在全球范围内传播，即使旧的创新具有先发优势。
We study the competition of two spreading entities, for example innovations, in complex contagion processes in complex networks. We develop an analytical framework and examine the role of dual users, i.e. agents using both technologies. Searching for the spreading transition of the new innovation and the extinction transition of a preexisting one, we identify different phases depending on network mean degree, prevalence of preexisting technology, and thresholds of the contagion process. Competition with the preexisting technology effectively suppresses the spread of the new innovation, but it also allows for phases of coexistence. The existence of dual users largely modifies the transient dynamics creating new phases that promote the spread of a new innovation and extinction of a preexisting one. It enables the global spread of the new innovation even if the old one has the first-mover advantage.
