摘要

最近的工作突出了美国新公司进入率的下降和大公司市场份额的上升。为了了解这些不断变化的企业人口结构如何影响增长,我们将生产力增长分解为进行创新的企业。我们通过开设和关闭工厂的速度、这些工厂的市场份额以及幸存工厂的生长速度来追踪每家公司的创新程度。利用1982年至2013年所有非农企业的数据,我们发现新企业和年轻企业(0至5岁)几乎占了增长的一半,是其就业份额的三倍。大型老牌企业虽然占就业人数的四分之一,但对经济增长的贡献仅为十分之一。在我们的样本中期,老公司确实解释了大部分的加速和减速。最后,大多数增长都是以在位者改进自己的产品的形式实现的,而不是创造性的破坏或新品种。

Innovative Growth Accounting
Recent work highlights a falling entry rate of new firms and a rising market share of large firms in the United States. To understand how these changing firm demographics have affected growth, we decompose productivity growth into the firms doing the innovating. We trace how much each firm innovates by the rate at which it opens and closes plants, the market share of those plants, and how fast its surviving plants grow. Using data on all nonfarm businesses from 1982–2013, we find that new and young firms (ages 0 to 5 years) account for almost one-half of growth – three times their share of employment. Large established firms contribute only one-tenth of growth despite representing one-fourth of employment. Older firms do explain most of the speedup and slowdown during the middle of our sample. Finally, most growth takes the form of incumbents improving their own products, as opposed to creative destruction or new varieties.
