Unveiling the Determinants and the Effects of Online Social

发布时间：2021-02-04 16:10

　　由于信息和通信技术的迅猛发展,信息传播渠道得到了很大扩展。以往,资本市场投资决策往往有赖于传统媒体、人际关联和与交易有关的出版资料。近年来,社交媒体的活跃用户已经大大增加,占到世界总人口的45%（38.5亿）。由于在线社交网络（OSNs）的迅速兴起,虚拟社区已发展成为流行的交流和娱乐论坛。它对用户的影响日益显著,尤其是资本市场投资者的投资决策。随后,在线社交网络迅速发展将成为全球新兴的信息传播平台。在当今世界,对于投资者（个人和机构）在资本市场的投资决策,在线社交网络的潜在影响已无法回避。迄今为止,学者们尚未广泛研究投资者在资本市场投资决策中使用该平台的情况,并且缺乏其在虚拟环境中进行决策的独特模型。本文试图确定促使投资者采用在线社交网络的决定因素,以及随着虚拟社区决策模型（VCDM）的发展,每个因素对投资者在资本市场上的投资决策的影响程度。对于研究1和3,采用在线和离线的结构化问卷从资本市场个人投资者收集的510个数据,对于研究2,采用以在线问卷在孟加拉国机构投资者收集的285个数据。数据分析使用结构方程模型（SEM）。第一项研究开发了一种分别从信息系统和营销学科将技术接受性模型（T...
