利用包含来自世界各地约1.5亿个企业规模数据的ORBIS数据库，我们调查了德国、西班牙、法国、英国、意大利、日本、韩国和荷兰的企业活动数据，发现西班牙企业活动的衰减率不像日本那样依赖于企业年龄。但在德国、法国、英国、意大利、韩国和荷兰，年轻公司的衰退率很高，随着公司的年龄增长，衰退率会降低，并稳定在一个恒定的值。通过用指数函数近似企业活动的衰减率，我们在假设每年成立的企业数量几乎不变，企业活动的衰减率每年不变化的情况下，分析地推导出了企业年龄分布。利用来自八个国家的经验数据，我们比较了由企业活动衰减率估计的参数与由企业年龄分布估计的参数。除西班牙和德国外，两种不同方法估计的两种参数彼此接近。
Using the ORBIS database that contains around 150 million firm-size data from all over the world, we investigated firm activity data in Germany, Spain, France, the United Kingdom, Italy, Japan, Korea, and the Netherlands and found that the decay rate of firm activities does not depend on firm age in Spain as in Japan. But in Germany, France, the United Kingdom, Italy, Korea, and the Netherlands, the decay rate of young firms is high and becomes lower and settles at a constant value as firms age. By approximating the decay rate of firm activities by an exponential function, we analytically derived the firm age distribution under the assumptions that the number of firms that is established annually is nearly constant and that the decay rate of firm activities does not change annually. Using empirical data from eight countries, we compared the parameters estimated by the decay rate of the firm activities with those by firm age distribution. Except in Spain and Germany, the two kinds of parameters estimated in two different ways were close to each other.
