虛擬社群涉入對於股票投資行為之影響

The Impacts of e-Stock-Investors' Involvement in Virtual Community on Their Investment Behaviors

摘要


本研究探討虛擬社群涉入對於股票投資行為之影響,係國內外首篇針對此議題所進行的大規模調查研究。實證結果發現,臺灣e股民的投資行為,不論是靜態的持股分散程度或是動態的投資進出頻次,均受到投資者虛擬社群的涉入程度所影響,更明確地說,個別投資人對於虛擬社群的參與深度(涉入時間)與其持股分散程度和交易頻次,都呈現顯著的正向關係。此外,本研究也發現,投資人對於虛擬社群的參與廣度(參與的社群網站數)較高者,較能積極設立停損且切實執行。此現象意味著,虛擬世界中的人際網絡並不「虛擬」,對於投資人的決策與行為已具有十分顯著的影響。本研究的成果發現,對於財務學中的投資行為與社會心理學的人際關係等議題之探討,都具有開創性的重要價值。

並列摘要


This study explores the impacts of e-stock-investors' involvement in virtual community on their investment behaviors. It is the first paper, as far as we know, discussing this issue systematically by a large-scale survey. The empirical results show that individual e-investors' involvement in virtual communities significantly affects their portfolio diversification and trading turnover. Specifically, when a Taiwanese e-investor spends more time in virtual community, he/she holds a more diversified portfolio and trades more frequently. In addition, when he/she attends more social websites, he/she is more inclined to do the loss-stops. It implies that the virtual community is not "virtual" and brings about significant influences on investment behaviors. The findings of this paper are insightful for the re-searches on the social networks analysis in Sociology, the interpersonal relationships in Social Psychology, as well as the investment behaviors in Finance.
