IPO折價發行在全世界的股票市場都是相當常見的現象，也因為如此，如何提升訂價的效率就成為被廣泛討論的議題。上市前交易平台的設立便是為了要增加即將IPO公司的資訊，藉以達到價格發現的效果。
臺灣擁有全世界唯一具有交易強制性的上市前交易平台-興櫃市場，這也提供了很好的機會可以對於興櫃市場的交易特性、資訊性以及其與IPO折價發行相關理論的關聯性加以了解。本研究蒐集了從2005年到2014年有先在興櫃交易，然後使用詢價圈購承銷進行IPO的436支IPO股票樣本，藉由重要時點的統計量觀察與迴歸分析，得到以下結論：

(1) 即便有先經過興櫃市場交易的資訊揭露，臺灣IPO股票仍然擁有極高的初始報酬。

(2) 興櫃市場交易的資訊性和市場流動性呈現正比關係；另外，隨著越接近訂價日，其所提供的資訊性也會提高，但效果並不佳。

(3) 興櫃市場交易價格和IPO承銷價格的關聯性並無法用資訊不對稱理論來解釋，同樣的，承銷費用和IPO折價之間的關係也沒有如承銷商競租行為般具有關聯性。

The IPO underpricing phenomenon is common all over the world, hence the most important issue is to improve the efficiency of IPO pricing. The establishment of pre-IPO market platform is to increase the information disclosure for the preparing firms, and also be expected to achieve the purpose of price discovery.
Taiwan has the only mandatory pre-IPO trading market in the world – Emerging Stock Market(ESM). So it provides an opportunity to understand the trading, the informativeness, and the association with IPO underpricing theory on the ESM market. Our research sample consists 436 firms that went IPO through bookbuilding underwriting between 2005 and 2014. By the observation on the statistics summary at critical time point and regression analysis, the finding of this thesis are as below：

(1) Even through the procedure of trading on ESM market, the IPOs in Taiwan still have high initial return.

(2) The informativeness of ESM price is positively related to liquidity of the market. In addition, as the date getting closer to the pricing day, the informativeness of ESM price also increase, but the effect is not good.

(3) The relationship between ESM price and IPO offer price cannot be explained well by theories based on asymmetric information. Also, the relationship between FPO fee and IPO underpricing cannot fit the explanation of rent-seeking behavior.
