    本文的主體由六個部分組成:第一部分介紹新股發行定價的估值方法;第二部分對我國的發行定價方式和發行制度進行分析,探討不同發行定價方式的優缺點,以及審批制和核準制經濟效率分析;第三部分從信息經濟學角度和其他因素的角度詳細分析造成新股發行抑價的原因,並結合我國股票市場實際情況,分析了我國市場的特有因素是否及如何影響一級市場的發行抑價程度的;第四部分利用統計分析軟體spss對我國新股行政化和市場化定價進行實證分析,主要包括新股發行行政化和市場化定價方式的實施情況和效果分析、新股發行行政化定價方式的實證分析,以及新股發行行政化和市場化定價方式的比較實證分析;第五部分利用統計分析軟體spss對我國新股發行審批制和核準制進行實證分析;第六部分是本論文的主要結論。本文的主要結論和建議有: ( 1 )從實證分析結果看,我國新股發行抑價與市場環境、發行市盈率呈顯著正向關系,與發行規模、申購中簽率等呈顯著反向關系。 ( 2 )取消發行市盈率限制和實施核準制等市場化改革措施並沒有降低發行抑價的絕對水平,只是由於市場環境的因素,發行抑價的相對水平才有所降低。
