自從我國於九十年與九十一年修正公司法與證券交易法後，我國企業的籌資管道又新增一項，此即為私募制度。私募是指發行股票之公司對特定人招募有價證券之行為。私募的主要好處有三，第一是縮短資金取得時間。第二是私募價格制定更有彈性。第三是公司對私募對象的選擇有更大的空間與主導權。
近年來，私募案件在國內日益蓬勃，且私募是否圖定特定人士也引發爭議，本研究認為私募對象將成為眾人的關注焦點，故嘗試探討私募對象在私募案中扮演的角色，本研究和先前文獻的不同之處在於，更進一步觀察公司內部人的行為，探討當大多數私募股數由公司內部人認購的情形下，私募股的訂價是否較低、股價表現又是如何；並研究公司內部人在私募前後申報轉讓持股情形是否暗藏玄機；融資融券情形是否也隱含有內線交易存在。
研究結果發現：
(一) 私募訂價方面：
實證發現，整體私募股權樣本多為折價發行。由敘述統計與迴歸結果來看，公司內部人皆不因己身具有內線消息優勢，擁有操控私募價格的能力，而以較低價將私募股賣給自己，反而還以較高價認購為公司增資，因此在股票訂價方面，似乎沒有圖利自己之嫌，打破媒體或投資大眾對公司內部人私相授受的質疑。
(二) 市場對私募案是否給予適當的反應
市場對於私募的宣告期股價反應皆為正，表示看好私募案的未來發展，然而，從依私募對象分類所繪製的股價走勢圖卻發現，私募給公司內部人的股價走勢，在私募後即一路往下，即使私募給公司內部人與私募後60 天的股價累積報酬之間的迴歸係數不顯著為負，但觀其股價趨勢圖，本研究仍認為，市場對於私募給公司內部人的案件過於樂觀，未能察覺之後滑落的公司價值。
(三) 公司內部人是否從私募中憑藉內線消息而得利
本研究特別針對私募股權樣本進行公司內部人申讓持股與融資融券情形的研究。發現在私募宣佈前後80 天內申讓情形有較密集的現象，表示握有公司私募消息的公司內部人可能仗著資訊優勢而有所動作，意圖從中得利，雖然密集度並非相當異常的高，申讓比率也未衝太高，但仍有立場質疑公司內部人此時申讓持股的動機與目的。而本研究的確也指出有幾家公司的有參與私募之內部人其申讓現象非常可疑，幾乎在私募同時中進行申讓的動作，且申讓價格高出私募價格許多，有明顯低價買新股、高價賣老股的套利現象。此印證了公司內部人有利用私募管道圖利自己的情形存在。更進一步，我們觀察融資融券情形，發現在私募宣布前多方與空方的確有異常的提前佈局現象，表示有內線交易之可能。上述之發現代表大
多數公司內部人即使在訂價時無明顯圖利自己的情形發生，但仍有部份公司內部人利用內線消息，意圖從中獲利。
