Abstract

In general, employment duration is influenced by the individual characteristics (level-1) as well as type of the occupational characteristics (level-2). That is, the data has hierarchical structure in the sense that individual employment duration is influenced by the individual-level variables (level-1) and the job-level (level-2) variables. In this paper, we study the determinants of the employment duration of youth-intern in the SMEs (small and medium enterprises) using Cox's mixed effect model. Major results at level-1 variables are as followings. First, the hazard rate of treatment group is lower than that of control group. Second, the hazard rate of woman is lower than that of man. Also, the hazard rate is lower, for the older and the workers working in the bigger company. Investigation of level-2 variables has shown that random effect for job-level is statistically significant.

취업자들이 재직기간이 경과하면서 이직 또는 실업 상태로 탈출확률 및 탈출요인 문제를 분석하는 것은 취업의 질을 측정할 수 있는 하나의 방법이다. 일반적으로 취업자들의 이직 또는 실업으로의 탈출확률은 취업자의 개인특성뿐만 아니라, 직종 특성에도 영향을 받는 복수의 분석단위를 가지게 된다. 복수의 분석단위를 가지는 위계적 (hierarchical) 자료구조에서는 직종별로 공유되는 특성이 존재하게 되어, 동일 직종 집단 내의 상관이 발생할 수 있다. 따라서 본 연구에서는 취업자 개인특성 (1-수준)과 직종 특성 (2-수준)의 위계적 자료구조 하에서 콕스의 비례위험 모형 (Cox's proportional hazard model)을 이용하여 중소기업 청년인턴사업에 참여한 취업자들의 재직기간 중 실직 및 이직으로의 탈출요인을 분석하였다. 분석결과를 요약하면 다음과 같다. 처리집단 (인턴집단)이 통제집단 (비인턴집단)에 비해서 탈출확률이 통계적으로 유의하게 낮음을 알 수 있다. 또한 남자들이 여자들에 비해서 탈출할 확률이 높고, 연령이 높을수록 탈출할 확률이 더 낮아지는 것을 알 수 있다. 그리고 기업규모가 클수록 탈출확률이 낮으며, 직종별로는 관리사무 관련직에 비해서 전문 서비스 관련직의 탈출확률이 더 낮게 나타났다.
