近年社會對於內線交易廣泛討論,新聞媒體報導看似內線交易案件量多,實際上內線交易案件量真的如此多嗎?以及內線交易的刑罰有無嚇阻性?本文將透過實證研究方法,從判決書中了解內線交易數量之變化、判刑之輕重、構成要件之審核等等,對比學說上的爭議,探討內線交易所欲規範的圖像以及過往之變革與未來之走向。本文利用實證的研究方法,致力與法條及學說對話,提出假設並加以檢驗,研究後發現,內線交易法之規定在實務上難以獲得彰顯,且其法律規定在效果上亦無顯著效果,而其學說上所認為最具爭議的爭點,在實務判決上影響並非所認為的具影響力,種種現象顯示,我們所認為的內線交易與實際的內線交易狀況有所出入,利用上述成果,期待能更加精確地看待內線交易,對內線交易日後修法能產生部分影響。;In recent years, insider trading has been extensive discussion in the community.
