By giving examples such as public-listed companies unwillingness or untruthfulness to carry out their information releasing obligations, inappropriate behavior of market agency, disfigurement existing in the process of lawmaking and executing laws, the paper has taken advantage of the well-known principles of economics to analyze the presentproblems plaguing our security market in our country, the results shows that there exists a great deal of incomplete information and asymmetric information at the security market, which can lead to moral hazard problem and adverse selection ,and both are the main causes that hinder the normal function of information disclosure mechanism, affect the market efficiency and allocation of financial resources. In addition, institutional objection at the security market is a crucial factor in arising the-above-said problems.

文章通过举例深入分析了当前我国证券市场存在的诸多问题，如上市公司不主动与非真实履行披露义务、中介机构行为失当、立法执法存在缺陷等，运用经济学一般原理剖析引起问题的深层次原因，指出证券市场存在大量不对称信息，容易导致市场道德风险和逆向选择，是阻碍信息披露机制发挥正常作用、影响市场效率的提升和资源的配置的主要根源；另外，我国证券市场存在的制度性缺陷也是引起上述问题的重要缘由。
