摘要 这项研究制定了一个模型，其中（i）玩家的特征是通过交流而内生变化的知识集，以及（ii）一些玩家具有同质偏好，而其他玩家则具有异质偏好。因此，该研究表明，异性参与者在早期阶段就桥接了不同的组件并扩展了网络，随后，同性参与者扮演了维持网络联系的网络枢纽的角色。它还说明了长期的知识分布。此外，该模型还嵌入了新的结构组件，这些组件说明了弱关系的强度和小世界现象。
ABSTRACT This study formulates a model where (i) players are characterized by a knowledge set that changes endogenously by communication and (ii) some players have homophily preferences, while others have heterophily preferences. The study thus demonstrates that heterophilous players bridge different components and extend networks in an early stage and, subsequently, homophilous players take the role of a network hub that maintains network ties. It also illustrates the long-run knowledge distribution. Further, the model is embedded with new structural components that illustrate the strength of weak ties and the small-world phenomenon.
