摘要：

本文針對(duì)信息不對(duì)稱下投資者異質(zhì)信念對(duì)股東財(cái)富效應(yīng)的影響問題進(jìn)行研究。首先，通過資產(chǎn)定價(jià)理論和市場(chǎng)微觀結(jié)構(gòu)理論，探討了信息不對(duì)稱和投資者異質(zhì)信念對(duì)股價(jià)的影響。其次，結(jié)合實(shí)證研究，重點(diǎn)分析了投資者信念、投資者對(duì)公司治理的信心和市場(chǎng)風(fēng)險(xiǎn)偏好對(duì)股價(jià)產(chǎn)生的影響。結(jié)果發(fā)現(xiàn)，信息不對(duì)稱下，投資者信念對(duì)股票市場(chǎng)的波動(dòng)具有重要作用，同時(shí)，投資者對(duì)公司治理的信心和市場(chǎng)風(fēng)險(xiǎn)偏好也會(huì)影響股價(jià)的波動(dòng)。最后，本文提出了一些針對(duì)這些因素的投資策略和建議。
