臺灣近年來高等教育逐漸普及，大學教育除了傳授知識外，也漸漸重視專業證照的考取，本研究探討大學生取得的專業證照，是否能夠反應其市場價值。本文以「台灣高等教育資料庫94學年度大專畢業後一年」的調查資料進行分析。首先了解大學畢業生考取國家考試、技術士、證券與期貨、教師資格、語言認證以及電腦認證六大類專業證照之情形，再進一步探討專業證照與勞力市場之關連，包括在不同的工作部門、產業型態下，證照對於薪資所得是否具有提昇之效。研究發現，若只論證照類型，證照的市場價值並不明顯，一旦區分出高階／低階之後，高階證照對於增加薪資等級有較為顯著的效果；至於低階證照，則可能帶來反效果。

The goal of college education in Taiwan is seen to expand to the acquirement of the so-called ‘professional certificates’ in recent years. This article, therefore, aims to explore whether certificate oweners thereby gain a wage increase. The research samples are college graduates in 2005. Utilizing the survey date of their career development within one year after graduation, I firstly present their results of acquiring certificates in six professional groups through national exams. These groups include qualifications for civil servants, skilled workers and teachers, qualifications for recognized proficiency in foreign languages and for approved computing capability, as well as licenses of representatives of securities and futures. Based on the breakdown, I then explore how these certificates affect the wage changes of their owners in different sectors and industries. My findings suggest that the certificates per se do not necessarily guarantee a wage increase. Instead, an advanced qualification seems to have a significant effect on a wage increase, while a basic one may hurt such prospects of its owner.
