摘要：The early 1990’s marked a turbulent period in Japan’s economic history. We reconstructed the non-aggregated data for 660,000 worker samples of the 1992 Employment Status Survey into the estimated data for all 64,000,000 workers in Japan using this government survey’s method and conducted unique analyses on the regional inequalities of worker incomes from the perspective of individual and regional disparities. The following results were obtained: (1) Clear individual income inequalities existed in accordance with the social attribute of workers framework. The gender-specific processes by which individual inequalities emerged were detected by the causal inference method. For women, great disadvantages were identified in income and employment status compared to men. (2) Particularly for men, clear regional income inequalities were found by the framework of zone/urban hierarchical systems. Regional factors for inequalities were formed by two kinds of effects: the regionally uneven distributions of workers with different social attributes/categories (compositional effects) and those of high-income workers within the same attributes/categories (hierarchical effects). (3) Analyzed by the Theil index, the component rates by the regional factors to the overall inequalities among workers were 6% for men and 3% for women. (4) By an experimental regression analysis for worker samples, about one third of the inequalities for men and women were explained by regional and social individual factors of workers. Over half of the variations of worker incomes were not explained by the regression model (probably caused by private individual factors of workers). Some contemporary meanings were found from this study for 1992.
