摘要

本文的研究目的是從信息不對稱的角度研究目前中國股票市場IPO抑價的現(xiàn)狀。本文的研究方法是定量研究，通過搜集2015年200組IPO的相關數(shù)據(jù)進行相關性分析和回歸分析。
本文的調(diào)查結(jié)果顯示，為了解決IPO抑價過高這個問題，中國的金融監(jiān)管部門自2010年先后實施了一系列的新制度和政策，但從本文的研究來看，我國的IPO的抑價水平還是很高。
政府頒布的這些新制度包括:限制了發(fā)行市盈率，限制了IPO首日的漲幅等等,但并沒有從根本上解決IPO抑價過高的問題，反而使得IPO定價不能真實反映企業(yè)內(nèi)在價值，不能真實反映供求關系，，進一步加大了普通投資者與企業(yè)，機構(gòu)和政府之間的信息不對稱。本文的結(jié)果顯示股本結(jié)構(gòu)，企業(yè)負債率，價格，市盈率，企業(yè)總資產(chǎn)，發(fā)行規(guī)模，中簽率，承銷商信譽這些因素都應該是造成IPO抑價水平增高的原因，其中價格，市盈率，發(fā)行規(guī)模，總資產(chǎn)，資本負債率與IPO抑價之間存在有統(tǒng)計學意義的線性的相關關系。基于此，筆者也推導出，贏者詛咒理論較好的解釋了中國IPO抑價的現(xiàn)象。最后，筆者從制度完善，投資者的教育，加強監(jiān)督三個方面為政府未來解決IPO抑價問題提出了建議。
關鍵詞：IPO，定價效率，抑價，發(fā)行價格，贏者詛咒理論
 
Abstract

The research purpose for this study was to study the current situation of IPO underpricing in Chinese stock market with the perspective of information asymmetry. 
This research used descriptive and multi regression analysis in order to examine how the variety of determinants can affect IPO underpricing in Chinese stock market. The chosen sample in the empirical research was 200 IPO Chinese companies in 2015. As results, there was a statistically significant linear correlation between an enterprise’s total assets, asset-liability ratio, issue scale, price-earnings ratio, issuing price and IPO underpricing rate. 
The results in this study present that China's IPO underpricing rate was still high. Although China's financial regulatory authorities have implemented a series of new systems and policies such as limiting issuing price-earnings ratio, limiting the amount of increase of IPO on first day of issue since 2010, it failed to solve the problem of high IPO underpricing rate and truly reflect the intrinsic value of enterprises. Based on the empirical result and literature review, the information asymmetry between investors, enterprises and the government seriously existed. The author deduces that the Winner's Curse theory better explains the phenomenon of China’s IPO underpricing. 
Keywords: IPO; pricing efficiency; underpricing; issuing price; the Winner's Curse theory
