　　由于信息和通信技術的迅猛發(fā)展,信息傳播渠道得到了很大擴展。以往,資本市場投資決策往往有賴于傳統(tǒng)媒體、人際關聯(lián)和與交易有關的出版資料。近年來,社交媒體的活躍用戶已經大大增加,占到世界總人口的45%（38.5億）。由于在線社交網絡（OSNs）的迅速興起,虛擬社區(qū)已發(fā)展成為流行的交流和娛樂論壇。它對用戶的影響日益顯著,尤其是資本市場投資者的投資決策。隨后,在線社交網絡迅速發(fā)展將成為全球新興的信息傳播平臺。在當今世界,對于投資者（個人和機構）在資本市場的投資決策,在線社交網絡的潛在影響已無法回避。迄今為止,學者們尚未廣泛研究投資者在資本市場投資決策中使用該平臺的情況,并且缺乏其在虛擬環(huán)境中進行決策的獨特模型。本文試圖確定促使投資者采用在線社交網絡的決定因素,以及隨著虛擬社區(qū)決策模型（VCDM）的發(fā)展,每個因素對投資者在資本市場上的投資決策的影響程度。對于研究1和3,采用在線和離線的結構化問卷從資本市場個人投資者收集的510個數據,對于研究2,采用以在線問卷在孟加拉國機構投資者收集的285個數據。數據分析使用結構方程模型（SEM）。第一項研究開發(fā)了一種分別從信息系統(tǒng)和營銷學科將技術接受性模型（T...
