公司规模的帕累托指数
Pareto index induced from the scale of companies
摘要：
利用2002年和2003年日本企业的利润数据，我们证实了帕累托定律和帕累托指数是由细致平衡定律和吉布拉特定律推导出来的。最后两个定律在帕累托定律成立的区域之外被观察到。通过将公司划分为不同的工作类别，我们发现小规模工作类别的公司比大规模工作类别的公司有更多的增长可能性。这从运动学上解释了小规模工作类别中的公司的帕累托指数大于大规模工作类别中的公司的帕累托指数。
英文摘要：
Employing profits data of Japanese companies in 2002 and 2003, we confirm that Pareto's law and the Pareto index are derived from the law of detailed balance and Gibrat's law. The last two laws are observed beyond the region where Pareto's law holds. By classifying companies into job categories, we find that companies in a small scale job category have more possibilities of growing than those in a large scale job category. This kinematically explains that the Pareto index for the companies in the small scale job class is larger than that for the companies in the large scale job class.
