【摘要】:證券市場的健康發(fā)展離不開較好的投資者權(quán)益保護(hù)。在證券市場中,上市公司公開披露高質(zhì)量信息不僅能有效的降低投資者之間的信息不對(duì)稱和交易成本,而且對(duì)保護(hù)(中。┩顿Y者都有著重要的意義。 本文以信息質(zhì)量理論、投資者信息解釋理論、投資者保護(hù)效果的理論為基礎(chǔ),基于投資者視角,在拓展價(jià)差模型和交易量模型的基礎(chǔ)上,嘗試探究信息質(zhì)量和信息解釋能力對(duì)中小投資者保護(hù)效果的影響。 研究發(fā)現(xiàn):(1)在信息不對(duì)稱市場中,專業(yè)投資者與非專業(yè)(中。┩顿Y者之間的信息解釋能力差異越大,,股票交易越活躍,發(fā)生信息性交易概率就越大,投資者之間的買賣價(jià)差就會(huì)越大,對(duì)非專業(yè)(中。┩顿Y者的保護(hù)效果減弱;(2)在信息不對(duì)稱市場中,新信息披露的質(zhì)量越高,專業(yè)投資者與非專業(yè)投資者之間的買賣價(jià)差減小,對(duì)非專業(yè)(中。┩顿Y者的保護(hù)效果增強(qiáng);(3)在信息不對(duì)稱市場中,若非專業(yè)(中。┩顿Y者把風(fēng)險(xiǎn)資產(chǎn)交由專業(yè)人員管理,使得所有投資者對(duì)公開披露信息的解釋能力相當(dāng),從而投資者之間的買賣價(jià)差顯著減少,非專業(yè)(中。┩顿Y者的保護(hù)效果增強(qiáng)。
[Abstract]:The healthy development of the securities market is inseparable from the better protection of investors' rights and interests. In the securities market, the public disclosure of high-quality information by listed companies can not only effectively reduce the information asymmetry and transaction costs among investors. And to protect (small and medium) investors have important significance. Based on the information quality theory, investor information interpretation theory, investor protection effect theory and investor perspective, this paper expands the spread model and trading volume model. Try to explore the impact of information quality and information interpretation ability on the protection of small and medium investors. The study found that in asymmetric information markets, the greater the difference in information interpretation ability between professional investors and non-professional (small and medium-sized) investors, the more active stock trading becomes, and the greater the probability of information trading occurs. The greater the spread between investors, the weaker the protection of non-professional (small and medium-sized) investors.) in an asymmetric information market, the higher the quality of new information disclosure, the smaller the spread between professional and non-professional investors. The protective effect of non-professional (small and medium) investors is enhanced. (3) in an asymmetric information market, if not professional (small and medium) investors manage their risky assets with professional personnel, all investors have the same ability to interpret public disclosure of information. As a result, the spread between investors significantly reduced, non-professional (small and medium-sized) investors enhanced the protection effect.
