本文使用「台灣青少年計畫」，檢視學歷和主修領域對薪資的影響。薪資的衡量爲第一份和最近一份工作時薪。在考慮三種大學類型下，學歷分爲未上大學、大學（私立、一般國立和頂尖國立大學）、研究所（私立大學、一般國立大學和頂尖國立大學研究所），主修分成「人文社會農」和「理工醫」。發現：（1）在未考慮主修領域下，同等學歷中，一般國立與私立大學的薪資無顯著差異，頂尖國立大學的薪資高於私立大學；（2）相同大學類型中，學歷的提升對薪資有正向影響。在考慮主修領域下，前述結果仍多數成立。（3）最高學歷的大學類型才對薪資有影響之效果。（4）在未考慮主修領域下，同等學歷中，不同大學類型在轉職薪資變化上無顯著差異，而研究所轉職薪資變化高於大學。即使考慮主修領域，這些結果仍多數成立。

The paper examines the effects of diploma and major on earnings. The analysis is based on a longitudinal panel survey from the Taiwan Youth Project. The measures of earnings are the logarithm of hourly wage for the first job and the most recent job. The college types are categorized into private college, regular national college, and elite national college. The majors are simplified into those related to Science, Technology, Engineering, Mathematics, or Medicine (STEMM) and others (non-STEMM). The highest degree is catagorized as lower than college, college (private college, regular national college, and elite national college), or master’s (master for private college, regular national college, and elite national college). Without considering the major field, the results show that (1) with the same diploma, there is no difference in earnings between private college and regular national college, but those with an elite national college degree have higher earnings than those with private college degrees. (2) A master’s earns more than a college degree within the same college type. If the major field is taken into consideration, most of the aforementioned results still hold. (3) Only the college type of highest degree has effects on earnings. (4) Assuming the same academic qualifications, there is no significant effect on earnings when transferring from first to the latest job. However, within the same college type, for those with a master’s, the change in earnings when transferring from the first to the most recent job is higher than for college graduates. These results still hold when the major field is considered.
