本文提出了一种估计企业生产率变化的方法。我们采用分位数方法，估计生存企业的生产率分布的变化。利用该方法，从平均变动和离散两个方面对1987年至2014年的日本生产率动态进行了分析。分析的主要结果如下：在繁荣或正常时期，生产率分布向右移动，生产率离散度减小。相反，在经济衰退期间，生产率分布向左移动，生产率分散扩大。分析也给出了定量的显着结果。在历史上罕见的2008年全球金融危机期间，日本制造业生产率的加权（简单）平均值仅下降了0.2%（5.4%）。我们发现，这一违反直觉的结果是由于生产率分布的形状发生了重大变化，并发现如果调整了分布形状变化的影响，危机将使生产率下降22%以上。
This paper presents an approach for estimating changes in firms’ productivity. We apply the quantile approach, which estimates the changes in the productivity distribution of surviving firms. Using this method, the paper clarifies productivity dynamics in terms of both average change and dispersion in Japan from 1987 to 2014. The main results of the analysis are as follows: During a boom or normal period, the productivity distribution shifts to the right and the productivity dispersion decreases. Conversely, during a recession, the productivity distribution shifts to the left and the productivity dispersion expands. The analysis also gives quantitatively significant results. During the historically rare global financial crisis of 2008, the weighted (simple) average of manufacturing productivity in Japan fell by only 0.2% (5.4%). We identified that this counter-intuitive result was due to a significant change in the shape of the productivity distribution and found that the crisis would reduce productivity by more than 22% if the effects of changing the shape of the distribution were adjusted.
