摘要通过分析包含大量日本企业1996-2006年期间详细财务状况的纵向微观数据集，研究了劳动生产率的分布。作者表明，劳动生产率在高生产率和低生产率范围内的分布遵循幂律分布。第二类广义贝塔函数渐近地再现了幂律函数，它被用来解释劳动生产率的分布。通过比较表征高、低生产率区间的幂律指数，发现制造业在低生产率区间的不平等程度大于高生产率区间。对于制造业，作者还澄清，低生产率范围内不平等的变化与GDP具有很强的相关性。此外，通过比较制造业和非制造业高生产率区间的幂律指数，发现非制造业的不平等程度高于制造业。
Abstract The distribution of labour productivity is investigated by analyzing the longitudinal micro-level data set which contains the detailed financial conditions of large numbers of Japanese companies over the period 1996–2006. The authors show that the distribution of labour productivity in both the high and low productivity ranges follows a power law distribution. The generalized beta function of the second kind, which asymptotically reproduces a power law function, is applied to explain the distribution of labour productivity. By comparing the power law exponents that characterize high and low productivity ranges, the authors show that for manufacturing industries, inequality in the low productivity range is larger than that in the high productivity range. For the manufacturing industries, the authors also clarify that the change of inequality in the low productivity range has strong correlation with GDP. In addition, by comparing the power law exponents of the high productivity range in the manufacturing and non-manufacturing industries, the authors show that the inequality of the non-manufacturing industry is higher than that of the manufacturing industry.
