本研究旨在以理工科系大學生為樣本，探討並建構家庭社經地位、成就抱負與預期薪資之理論模型。研究以胡悅倫（2008）建構之資料庫為樣本，抽取1,084名理工科系大學生為研究對象，以變異數分析、卡方考驗及結構方程模式建構其路徑關係模式。研究結果顯示： 一、家庭社經地位對個體的成就抱負與預期薪資有正向的影響。父母職業聲望和教育程度較高者有較高的成就抱負和預期薪資。 二、家庭社經地位會透過成就抱負為中介，間接影響個體的預期薪資。 三、男女性在成就抱負上無顯著差異，但在預期薪資中男性的預期薪資會高於女性的預期薪資。 四、男性會進入男性化職業，女性會進入女性化職業。 五、預期進入男性化職業工作者的預期薪資高於進入女性化職業的工作者，而這樣的差距是跨性別存在。 最後，研究者根據研究結果提出建議，供實務工作者與後續研究者參考。 / The purpose of this study is to investigate and build a model on how family socioeconomic status affects achievement aspiration and anticipated salary. Participants are 1,084 Science and Engineering students from the database compiled by Yueh-Luen Hu (2008). Data analysis includes one-way ANOVA, t-test, chi-square test, and structural equation modeling. Results of the study are as follows: 1. Family socioeconomic status had significant positive effects on achievement aspiration and anticipated salary. Participants who are of higher socioeconomic status also had higher achievement aspiration and anticipated salary. 2. Achievement aspiration acted as a mediator between family socioeconomic status and anticipated salary. Achievement aspiration had significant indirect effects on anticipated salary. 3. The gender differences in achievement aspiration are non-significant. However, Men’s pay expectations are higher than of the women’s. 4. Males prefer to enter male-dominated jobs, while females prefer to enter female-dominated jobs. 5. Those who hold female-dominated jobs expect to gain less pay than those pursuing male-dominated jobs. The gap exists for both men and women. Results of the study shall serve as a point of reference for future researches.
