论文摘要
期刊的影响和与竞争对手的相似性与其竞争强度密切相关。主题领域可以视为期刊的生态系统，然后可以使用植物系统的竞争强度概念来测量。根据期刊引文报告1997年，2000年，2005年，2010年和2013年的数据，我们计算了真菌学期刊的相互引用，余弦相似性和竞争关系矩阵。根据2013年的期刊引文报告数据，我们得出了真菌学的相互引用网络。我们计算了每个期刊的竞争压力以及该主题的竞争强度。我们发现，竞争压力在期刊之间是非常可变的。期刊的绝对影响和相对影响之间的差异与竞争压力有关。更强大的期刊具有较低的竞争压力。新期刊的竞争压力更大。如果没有其他影响，那么受试者的竞争强度将继续增加。此外，我们发现，如果一个受试者有更多的期刊，其竞争强度会降低。
A journal's impact and similarity with rivals is closely related to its competitive intensity. A subject area can be considered as an ecological system of journals, and can then be measured using the competitive intensity concept from plant systems. Based on Journal Citation Reports data from 1997, 2000, 2005, 2010, and 2013, we calculated the mutual citation, cosine similarity, and competitive relationship matrices for mycology journals. We derived the mutual citation network for mycology according to Journal Citation Reports data from 2013. We calculated each journal's competitive pressure, and the competitive intensity for the subject. We found that competitive pressures are very variable among journals. Differences between a journal's absolute and relative influence are related to the competitive pressure. A more powerful journal has lower competitive pressure. New journals have more competitive pressure. If there are no other influences, the competition intensity of a subject will continue to increase. Furthermore, we found that if a subject has more journals, its competitive intensity decreases.
