摘要
在网络议程设置研究中,对于多用户之间相互影响、传导议程的网络结构重视度不足.该研究尝试从主体间议程设置网络的角度,强调在不同影响力的用户层级之间由近及远、先近后远、近强远弱的"梯度"议程设置网络结构.经过数据抓取和对用户分层,把不同层之间相互传导、设置议程而形成的网络视作关系矩阵.实证检验发现:任意两用户层之间议程传导程度,与这两层的粉丝数量之差距成反比,与这两层在粉丝量差距矩阵的接近中心度之和成正比.论文重视议程设置网络的结构分析、扩展议程设置网络理论,有助于社交网络中的议程设置路径及其最优网络的调控.
Abstract
In the research of online agenda setting,there is insufficient emphasis on the network structure of mutual influence and agenda transmission among multiple users.This study attempts to emphasize the"gradient"agenda setting network structure from the perspective of inter subject agenda setting network.Through data mining and user segmentation,the network formed by transmitting and setting agendas between different layers is regarded as a relational matrix.Empirical testing found that the degree of agenda transmission between any two user layers is inversely proportional to the difference in the number of fans between these two layers,and directly proportional to the sum of the closeness centrality in the fan gap matrix between these two layers.The paper emphasizes the structural analysis of agenda setting network and extends the theory of agenda setting network,which helps to regulate the agenda setting path and optimal network in social networks.
