我國專業證照對勞工薪資影響之研究

Abstract

本研究旨在驗證勞工持有專業證照，是否對其薪資的提升有所幫助，根據Becker(1975)的人力資本理論以及Spence(1973)的篩選理論，兩理論皆認為勞工可藉由取得專業證照來獲取較高的薪資水準。 因此本研究將利用民國九十六年『勞工生活及就業狀況調查』此次級資料，來針對台灣地區15歲以上參加勞工保險之本國勞工進行研究，欲藉由迴歸分析來進一步探討，勞工持有專業證照是否會對其薪資造成影響。 研究結果顯示，在控制其他因素下，勞工持有專業證照將能反映在較高的薪資水準上。而不同類型的專業證照對於勞工薪資的影響也不盡相同，勞工將可藉由取得專門職業及技術人員考試及格證書以及金融從業人員證照來獲取較高的薪資，至於持有技術士證照、電腦證照、語文認證、其他類證照的勞工，相較於未持有專業證照的勞工，將不會擁有較高的薪資所得。而專業證照對於不同教育程度勞工的影響，也將有所差異，教育程度較低的勞動者，將可藉由取得專業證照，使其所獲薪資提高，而教育程度較高的勞動者，取得專業證照與否，將不會對其薪資有太大影響。

The purpose of this paper is to examine the wage effect of professional certifications. According to the human capital theory and the signaling theory, individuals with professional certifications can have higher wages. Therefore, in this study, we use the 2007 labor life and employment survey for the regression analysis to examine the effect of professional certifications on individuals’ wages in Taiwan. Our empirical results confirm that individuals can have higher wages by getting professional certifications. Different kinds of professional certification will lead to discrepancy on individuals’ wages: financial certifications and professionals and technologists certifications have positive wage effects, while technical certifications, computer certifications, language certifications and other certifications have insignificant effects. The results also indicate that the wage effects of professional certification s vary with individuals’ education levels. Individuals with lower education level can have more wage increases by getting professional certifications.
