為了解轉系對在學成績和畢業一年薪資的影響，本研究採用國立中央大學校務研究中心提供的在學成績資料和畢業生流向追蹤問卷調查的串聯資料，以民國99至104年入學的學士班畢業生為樣本，並根據轉系與否，以及轉系的領域分為六種情況，進行兩部分的迴歸分析。第一部分是對在學成績的研究，第二部分是對畢業一年薪資的研究。研究發現，不管是就讀理工科還是文科，未轉系者的成績表現皆比參考組文組轉文組要來得好，其餘有轉系的人則是和參考組沒有顯著差異；當固定離校科系時，理工科維持理工科和理工科轉理工科的薪資皆顯著比參考組要來得高。女性的成績顯著比男性高，但薪資和男性則沒有顯著差別。前四學期的成績對四學期後的成績有著非常大且顯著的影響，但四學期後的成績對畢業一年的薪資沒有顯著影響。有休學過的人成績顯著低於沒有休學過的，但是否休學過對畢業一年的薪資表現沒有顯著影響。不同學習經驗中，參考組校外業界實習的成績比語言學習、社團活動和志工服務服務學習都來得好，參考組的薪資表現則是比語言學習和參與國際交流活動都來得差。相較於參考組，語言學習對成績雖然是負向影響，但在薪資表現上和有進修或考試的人一樣有正向影響。;To investigate the effects of changing majors on academic performance and one-year post-graduation salary, this study utilized a linked dataset comprising academic performance data provided by the Office of Institutional Research at National Central University and the Follow-Up Survey of Graduates, which tracked the career paths of graduates. The sample consisted of bachelor′s degree graduates enrolled between the years 2010 and 2015. Further analysis was conducted by categorizing the sample into six groups based on whether they changed majors and the degree of interdisciplinarity in the major change. Two separate regression analyses were performed: the first part focused on studying academic performance, while the second part examined one-year post-graduation salary. The study finds that regardless of studying in STEM (Science, Technology, Engineering, and Mathematics) or non-STEM fields, students who did not change their major perform better academically compared to those who changed their major. In terms of one-year post-graduation salary, students who remained in STEM majors or switched within STEM majors have significantly higher salaries compared to the reference group. Female students have significantly better academic performance than male students, but there is no significant difference in terms of salary. The grades in the first four semesters have a significant impact on the grades after the first four semesters, but the grades after the first four semesters do not significantly affect the one-year post-graduation salary. Students who took a leave of absence have significantly lower grades compared to those who did not, but taking a leave of absence does not significantly impact the one-year post-graduation salary. Among different learning experiences, the reference group who participated in off-campus internships perform better academically compared to those engaged in language learning, extracurricular activities, and volunteer service learning. However, the reference group′s salary performance is lower compared to those who participated in language learning and international exchange activities. Although language learning has a negative impact on academic performance, it has a positive impact on salary performance similar to those who pursued further studies or took exams.
