研究表明，个人可以从战略性地建立个人网络中获益。有两种基本的网络方式：结构变化，即增加或删除通信联系；频率变化，即增加或减少现有联系上的通信。现有的文献主要集中在结构变化上，而对频率变化的潜力研究不足。为了研究结构和频率变化对网络中信息流效率的不同影响，我们在一组不同的现实世界的有向加权通信网络上进行了网络方法的模拟。我们的研究结果表明，总体而言，频率变化比结构变化与更高的效率相关，除了一个研究案例。结构变化对积极修改个人网络的个人有强烈的直接影响。令人惊讶的是，我们的模拟还表明，频率变化的间接影响（即，个人的关系因他人的行为而重塑）可以超过直接影响。我们的研究结果强调了迄今为止研究较少的频率变化的价值，并建议使用有针对性的网络改变可以在整个网络的规模上获得信息流的收益。
Research shows that individuals benefit from setting up their personal networks strategically. There are two fundamental networking approaches: structural change, which involves the addition and deletion of communication ties, and frequency change, which means an increase or decrease of communication on existing ties. Existing literature has focused predominantly on structural change, leaving the potential of frequency change understudied. To investigate the differential effects of structural and frequency change on the efficiency of information flow through a network, we conduct simulations of networking approaches on a diverse set of real-world directed weighted communication networks. Our results indicate that, overall, frequency change is associated with higher efficiency than structural change in all but one of the studied cases. Structural change has a strong direct effect on individuals who actively modify their personal network. Surprisingly, our simulations also show that the indirect effects of frequency change (i.e., an individual’s ties are reshaped due to others’ actions) can exceed direct ones. Our results highlight the value of the so far less studied frequency change and suggest that using targeted network alterations can result in gains for information flow at the scale of the entire network.
