Using cross‐country establishment‐level data, I show that employment profiles over a firm's life cycle are flatter in fast‐growing economies than in slow‐growing economies. The difference in average employment over the firm's life cycle increases with plant age. I propose a frictionless overlapping‐generations model with exogenous technological progress. Firm productivity also depends on entrepreneurs’ skills. Entrepreneurs can increase their skills over their life cycle, but the growth of the vintage component of younger cohorts’ skills is higher in fast‐growing economies than in slow‐growing economies. This model is able to explain most of the differences observed in the sample between fast‐growing and slow‐growing economies.

创业技能，技术进步和企业成长*

我使用跨国企业层面的数据显示，在企业生命周期中，与快速增长的经济体相比，在快速增长的经济体中的就业状况更为平坦。随着公司年龄的增长，公司整个生命周期中平均雇佣人数的差异会增加。我提出了具有外在技术进步的无摩擦重叠世代模型。公司的生产力还取决于企业家的技能。企业家可以在其整个生命周期中提高自己的技能，但是年轻群体的技能的老式组成部分在快速增长的经济体中要比在缓慢增长的经济体中要高。该模型能够解释样本中快速增长和慢速经济之间的大多数差异。
