Abstract: The paper constructs an evolution model of herding behavior based on transformation of private information, and points out that the evolution of herding behavior presents a character of “appeared→enhanced→weekend and disappeared→opposite herding behavior appeared→enhanced→weekend and disappeared…” driven by positive feedback effect, saturation effect and return reversal led by investors’ overreaction in the process of private information transferring to public information. An empirical research of Chinese A-share market shows that cyclical herding behaviorwith thecharacteristics above does exist.

Key words: transformation of private information, cyclical herding behavior, positive feedback effect, saturation effect, reversal

摘要: 论文构建了一个基于私人信息传递的羊群行为演化模型,指出,在私人信息不断转化为公共信息的过程中,受正反馈效应、饱和效应和投资者过度反应引发收益的反转驱动,羊群行为呈现“出现→增强→减弱、消失→反向羊群行为出现→增强→减弱、消失…”的周期性演化规律。基于我国A股市场的实证显示,上述特征的周期性羊群行为的确存在。
