박사학위 취득을 후회하지 않는 이유: 로지스틱 회귀분석과 랜덤 포레스트 분석을 통한 박사학위 가치 인식의 결정요인 탐색 = Why I don’t Regret Getting My PhD: Exploring the Determinants of PhD Value Perception Using Logistic Regression and Random Forest Analysis

다국어 초록 (Multilingual Abstract)

This study utilized data from the Korean Survey on Careers and Mobility of Doctorate Holders 2021 (N=3,131) to empirically explore the significant determinants of the value that Korean PhDs attach to their doctorates(If you were to go back to the point of entry into graduate school, would you value the PhD enough to choose to pursue it again?). The sample was divided into the total sample and the employed sample, and binary logistic regression analyses were conducted with the dependent variable of the choice to pursue a PhD again, followed by a random forest analysis for the employed sample. The results showed that the predictive performance of the three models was high, and that satisfaction with the doctoral program, satisfaction with the doctoral major, doctoral major, age at the time of obtaining the doctorate, relevance of the doctorate to the current job, overall satisfaction with the current job, current annual income, satisfaction with the current annual income, and characteristics and types of the current job were the factors that had a significant impact on the choice to pursue a PhD again. Based on the findings, policy implications for graduate education and employers of PhDs are discussed.
