中文摘要：

应用过度自信这一认知决策领域的稳健发现，行为经济学成功地解释了许多市场异象，但关于过度自信本身的产生原因与机制研究明显滞后，目前这一主题的研究主要有三种视角，即从人类认知过程出发的认知视角、从过度自信行为的实际结果出发的功能视角、从环境选择与适应性出发的演化视角。认知视角和功能视角有其难以克服的固有缺陷，演化视角富有前途但目前仍有明显不足，需要结合认知视角和其他认知偏差对过度自信产生之谜进行跨学科深化研究。

英文摘要：

With the robust found of overconfidence in cognitive decision field, behavioral economists have explained many market anomalies successfully, but the study on the cause and nature of overconfidence itself has been lagged obviously. There are three main perspectives of current research on this topic. The first is cognitive perspective which focuses on the human cognitive processes of overconfidence, the second if functional perspective which focuses on the actual function of overconfidence and the third is evolutionary perspective which focuses on environmental selection and adaptive evolution of overconfidence. Cognitive perspective and functional perspective have some inherent flaws, evolutionary perspective has bright future, but there are still some obvious inadequate about evolutionary perspective and deepen interdisciplinary research with the combination of cognitive perspective on the mystery of overconfidence bias is required.
