Abstract |

内容記述 |
This study examines two decades of unionization trends in Japan, comparing administrative data from the Basic Survey on Labor Unions (OECD source) with three population-based surveys: the Survey on Work and Life of Workers (SWLW), Japan Household Panel Survey (JHPS), and Japanese General Social Survey (JGSS). While official statistics show declining union density (falling to 16.4% by 2022), survey data reveal consistently higher rates (23-30%) and upward trends. Using shift-share analyses and Blinder-Oaxaca decomposition across two periods (X and Y), we identify workplace union presence as the primary driver of membership growth, accounting for a quarter of the observed increase. We find rising unionization among traditionally underrepresented groups: part-timers show significant unexplained membership gains (0.25 percentage points), suggesting successful outreach beyond compositional changes. Small firms (<100 employees), despite low absolute unionization, contribute positively to presence expansion. In contrast, workers’ demographic characteristics (education, age) demonstrate negligible effects. The persistent discrepancy between administrative and survey data underscores the need to address data collection methodologies to better inform labour policy. Our findings indicate that Japanese unions are adapting to structural changes by expanding into small firms and non-standard employment, a development that is not captured by conventional metrics but crucial for understanding contemporary industrial relations in Japan. |
