公司法為財經法之一，財經法律不同於民法和刑法，為了配合現在變化快速的經濟社會，在規範上更有彈性、調整的速度更快。公司法在修正的過程中，曾將過去許多違反特定事項的刑事處罰規定刪除或是修正。 而公司法中，資本為一重要概念，為保護資本健全，法律上訂有資本不實之規定，並且有刑事、民事以及行政上之責任。但在上述提及的公司法修正中，卻不見資本不實的刑事責任有調整的跡象。資本不實是否仍需要有刑事處罰，公司法第9條中的規定是否完善，是本文欲探討之議題。 本文藉由先分析我國之法規以及相關研究，並且做實務上的判決統計，來瞭解我國目前在資本不實的議題上有哪些討論以及那些問題，再參考日本法制對於虛假出資的規範，以此提出對我國資本不實規範的修正建議。 Company Act is one of financial law.
