「行政調查」係行政機關為行使其權限、達成行政目的，事先必須收集各 種情報資料之行為，包括質問、進入、檢查及調查等。例如對違反法令之業者 或個人，於決定應否予以警告、命令停止營業或廢除許可時，非對其違反法令 之行為事先加以掌握時，可能作出錯誤決定。近年來有關行政調查之討論日趨 增多，且關於行政調查制度之建構及學理之探討論著頗多。我國行政程序法有 關行政調查部分尚於第1 章第6 節設有「調查事實及證據」之規定，對於行政 調查之進行在第39條及第40條分別定有明文，並賦予行政機關行政調查權行 使之法源，然為概括、一般性之規定，尚有不足；又行政罰法雖於裁處程序中 有相關調查程序之規範，惟該程序似僅就違反行政義務受裁罰行為人身分之查 驗、沒入證物之扣留等處置程序之規定，而未對其人身自由、住宅之侵入等調 查手段及程序要件予以規範，故為使行政法上調查程序更臻周延，尚有就行政 罰法調查程序規定不足之處，詳予檢討之必要，爰藉由本文之研究，提供日後 修法之參考。

"Administrative investigation" is the act of the administrative organ to collect all kinds of information, including questioning, entry, inspection and investigation, in order to exercise its authority and achieve administrative purposes. For example, if the operator or individual who violates the law decides whether to warn, order to suspend business or revoke the license, it may make a wrong decision when it is not in advance to control the violation of the law. In recent years, the discussion on administrative investigations has been increasing, and there are many discussions about the construction and academic exploration of the administrative investigation system. The ad- ministrative investigation section of the Administrative Procedure Law of our country still has the provisions of "Investigation of facts and evidence" in Section 6. The administrative investigation is carried out in Articles 39 and 40 respectively, and the administrative agency is given the power to exercise administrative investigation. The source of law, however, is general and general, and there are still some shortcomings; although the administrative penalty method has the relevant investigation procedures in the procedure of the ruling, the procedure seems to only be for the inspection of the identity of the person who violates the administrative obligation, and the confiscation The procedures for detaining and other disposal procedures are not regulated by the means of investigation and procedures for personal freedom, intrusion of housing, etc. Therefore, in order to make the investigation procedure of administrative law more complicated, there are still insufficient provisions for the administrative punishment investigation procedure. It is necessary to review and provide a reference for future revisions through the research in this paper.
