【摘要】：由于计算机技术、网络技术和通信技术的快速发展,互联网得到了广泛的应用。互联网用户的需求不单单局限于追求个人体验,更是将更多的注意力放到知识的共享和交流之上。自此,互联网出现了新型社区——虚拟社区。虚拟社区的跨时空特性、互动性、开放性以及自治性等特点日益得到用户的喜爱和业界的看好。本文以复杂网络为视角,探讨了虚拟社区知识传播网络的形成过程。本文首先对虚拟社区知识传播过程的影响因素进行研究,提出了虚拟社区知识传播模型,即人际传播模型和人机传播模型。在此基础上,借助Netlogo仿真平台模拟了在不同条件下虚拟社区知识传播过程网络的形成过程。通过对仿真结果分析,本研究发现： (1)识别了网络中传播次数最多的节点是虚拟社区知识传播的关键传播者； (2)验证了虚拟社区知识传播过程的关键节点在一定程度上存在“马太效应”； (3)发现了影响虚拟社区知识传播速度的四个条件,即节点个数、知识接受者学习吸收系数、知识传播者的自我增长系数以及知识水平的差距。在某种程度上,增加节点个数,增大知识接受者学习吸收系数、知识传播者的自我增长系数以及社区水平的差距,会加速虚拟社区知识传播速度,从而加快虚拟社区知识传播网络的形成。本研究的理论意义在于不仅提供了一个全新的研究视角以探索虚拟社区中知识共享的微观机理,能够从更高层次上深化和扩展当前知识共享理论和虚拟社区管理理论,深化和扩展了知识传播理论的研究工作；实践意义在于通过探寻虚拟社区知识传播速度的影响条件,为研究如何提高虚拟社区的知识共享效率提供了依据。
[Abstract]:With the rapid development of computer technology, network technology and communication technology, the Internet has been widely used. The needs of Internet users are not limited to the pursuit of personal experience, but also focus more attention on knowledge sharing and communication. Since then, the Internet has emerged a new type of community-virtual community. The cross-temporal, interactive, open and autonomous characteristics of the virtual community are increasingly popular with the users and the industry. From the perspective of complex network, this paper discusses the forming process of knowledge dissemination network in virtual community. In this paper, the factors influencing the process of knowledge communication in virtual communities are studied, and the models of knowledge communication in virtual communities, namely interpersonal communication model and human-computer communication model, are put forward. On this basis, the forming process of knowledge transmission process network in virtual community under different conditions is simulated by using Netlogo simulation platform. By analyzing the simulation results, it is found that: (1) the node with the highest number of times in the network is identified as the key communicator of knowledge transmission in the virtual community; 2) verify the existence of "Matthew effect" in the key nodes in the process of knowledge dissemination in virtual community; 3) four conditions affecting the speed of knowledge transmission in virtual community are found, namely, the number of nodes, the learning absorption coefficient of the knowledge receiver, the self-growth coefficient of the knowledge communicator and the disparity of knowledge level. To some extent, increasing the number of nodes, increasing the learning absorption coefficient of knowledge receivers, the self-growth coefficient of knowledge communicators and the disparity at community level will accelerate the speed of knowledge transmission in virtual communities. In order to speed up the formation of virtual community knowledge dissemination network. The theoretical significance of this study is that it not only provides a new research perspective to explore the micro mechanism of knowledge sharing in virtual communities, but also can deepen and expand the current knowledge sharing theory and virtual community management theory at a higher level. It deepens and expands the research work of knowledge dissemination theory, and the practical significance lies in the research on how to improve the efficiency of knowledge sharing in virtual communities by exploring the influence conditions of the speed of knowledge transmission in virtual communities.
