Survival Analysis on the labor mobility of irregular workers by employment types in Korea

국문 초록 (Abstract)

한국에서의 비정규직 연구는 연구자마다 상이한 비정규직 개념을 사용했고 사용한 데이터도 달라서 비정규직 규모에 상당한 차이가 나타났으며 그에 따라 연구결과가 영향을 받는 문제가 있었다. 또한 기존 연구들은 비정규직들을 하나의 덩어리로 연구했기 때문에 비정규직간에 존재하는 내적 이질성도 보지 못하였다.
본 연구는 고용노동부의 「비정규패널」을 활용하여 2개년의 관찰 값을 토대로 ⅰ) 비정규직의 노동이동이 함정인지의 여부 ⅱ) 비정규직의 노동이동에 어떤 변수들이 영향을 미치는가를 분석하였다. 6개의 비정규직 고용형태간에 존재하는 중복계산(double counting)을 제거하였고, 확장형 Cox 해자드 모형과 경합적 위험 모형을 사용하였다.
분석 결과에 의하면 지속함정가설이 지지되었고, 기간제와 비교하여 다른 비정규직들의 정규직 전환율이 저조하였다. 또한 여성, 고령자, 저학력자, 근속이 짧은 자, 유노조사업장의 정규직 전환율이 낮았다.

On the study of irregular employment in Korea, its scale shows sizable variance and empirical results are not consistent as researchers use different definitions of irregular workers and data. Further, previous studies took blanket approach without classifying irregular workers by employment types and failed to present heterogeneity among them.
Using two years of Panel Data of irregular workers, this study analyzes 1) whether labor mobility of irregular workers is a trap or a stepping stone; and 2) which explanatory variables bring impacts on the mobility. Double counting is eliminated among six types of irregular workers. Extended Cox Hazard Model and Competing Risk Model are applied for analysis.
Findings show that durable trapping hypothesis is supported. Compared with fixed-term workers, the transition rate of other irregular workers was lower and women, the aged, the low-educated, workers with shorter length of service, unionized workplaces significantly show less transition rate to regular workers.
