中文摘要: 注意力在投资决策和资产价格形成中扮演着重要角色,但传统资产定价领域的信息不对称理论和行为金融学都未对其给予足够重视(Camerer,2003)。因此本课题结合"股票交易龙虎榜"、"盈余公告"和"股吧"论坛三个典型事件,重点探讨注意力是否以及如何影响中国投资者的股票交易行为这一基本问题。在研究注意力是否影响投资者行为时,我们不仅关注过度注意,而且探讨注意力不足。除个人投资者,机构投资者也是我们的研究重点。在研究注意力如何投资者行为时,我们不仅探讨投资者的股票买入行为,而且关注国际学界忽视的股票卖出行为。最后,除探讨正式信息,我们还侧重分析非正式信息传播渠对投资者注意力的影响。因而,该研究能够丰富和完善投资者行为以及注意力与资产定价等领域的相关研究成果。同时,我们所选择的研究事件能够较好地解决该领域国际学术文献中难以避免的内生性问题以及干扰事件潜在影响难题,从而使该领域的相关结论更为稳健。

英文摘要: Although investor attention is very important in investments and assets pricing, it is largely ignored in information asymmetry field and behavioral finance theory. We investigate whether and how attention affects investor behavior in China, using three events such as "Dragon and Tiger List", "Earning announcements" and Internet Stock Message Board. We study not only the investors' over-attention and limited attention, but also the buying and selling behavior.We also compare the impact of investor attention on different investors such as individual and institutional investors. Furthermore, informal information transmission channel is also our focus in this study. Therefore it contributes to attention field in many aspects. It also evades endogeneity and solves the confounding event problem in international studies. Our findings will help policy-makers understand the investor behavior and the market efficiency in China.
