개인주도 직업훈련 시장에서 훈련기관의 생존: 조직생태학적 니치 특성과 밀도 의존성 분석 = Training Provider Survival in an Individual-Driven Vocational Training Market: An Organizational Ecology Analysis of Niche Characteristics and Density Dependence

다국어 초록 (Multilingual Abstract)

This study examines the individual-driven vocational training ecosystem from an organizational ecology perspective and proposes policy tasks to restructure Korea’s vocational training market. Using HRD-Net microdata from 2021 to 2023, this study introduces the concept of a supply-based niche, defined by the training occupation and geographical location of training institutions, and a demand-based niche constructed from the gender, education level, and age combinations of trainees. Accordingly, this study measures niche diversity, dominant niche share, and effective diversity within the individual-driven training market.
Furthermore, this study empirically analyzes how provider tenure (years since entry into the individual-driven training market), density dependence (representing the level of competition within a niche), and other niche variables influence the exit (withdrawal) of training institutions. The results confirm the presence of density dependence in Korea’s individual-driven vocational training market and reveal that niche-related factors exert a stronger impact on provider exit than density dependence alone.
