公司规模的分析历来使用的数据，包括有限的样本的小公司，数据通常描述的对数正态分布。使用美国纳税公司的全部数据，我在这里展示了齐普夫分布对公司规模的表征：公司规模大于s的概率与s成反比。这些结果适用于多年的数据和不同的企业规模定义。
Analyses of firm sizes have historically used data that included limited samples of small firms, data typically described by lognormal distributions. Using data on the entire population of tax-paying firms in the United States, I show here that the Zipf distribution characterizes firm sizes: the probability a firm is larger than size s is inversely proportional to s. These results hold for data from multiple years and for various definitions of firm size.
