利用共同薪資隨機邊界函數評估臺灣地區大學商學院績效

Efficiency Performance of Colleges of Business in Taiwan － An Application of Stochastic Metafrontier Approach

為考量台灣高教學校之異質性，本文應用隨機性共同邊界法來評估台灣之大學商管學院的辦學績效；利用畢業生的起薪及目前薪資，我們建立了薪資邊界函數，並藉此驗證Spence (1973) 教育訊號理論及Mincer (1974) 人力資本理論，在台灣高校之合宜性。研究結果顯示：高校生職場存在教育訊號及人力資本理論之現象，但雇主在起聘時會普遍高估學校品牌價值。此外，學校經營技術之差異會受到學校的類別、品質及區位等客觀條件的影響。

To incorporate the property of heterogeneity in Taiwan higher education industry, this paper adopts the stochastic metafrontier approach to evaluate the operation efficiency of commercial college in university of Taiwan. Using college graduates’ starting wage and current wage survey data, we develop the wage frontier functions. We empirically estimate the proposed wage frontier functions to evaluate the operation efficiency of commercial colleges and to examine the appropriateness of the Signaling theory of Spence (1973) and the Human Capital theory of Mincer (1974) applied to the job market of Taiwanese college graduate. Research results have evidenced the existence of such two theories in college graduate job market of Taiwan. We find that employers often over evaluate the school value in offering starting wage to college graduates. We also find that the school’s operation technology is significantly affected by school type, quality and location.
