本研究利用埃塞俄比亚制造业企业的年度普查面板数据，考察了企业增长与企业规模、年龄和劳动生产率之间的关系。该研究明确解决了企业增长模型中持续存在的统计问题，如样本删失，回归均值和未观察到的异质性。我们的实证结果表明，企业的增长与规模下降。即使在补偿了较高的流失率之后，小公司的增长速度也比大公司快。年龄和增长之间的负相关关系的学习模型预测发现，只适用于年轻的企业。劳动生产率对企业增长有正向影响，表明埃塞俄比亚经济改革时期存在市场选择过程。
This study examines the relationships between firm growth and firm size, age, and labor productivity, using annual census–based panel data on Ethiopian manufacturing firms. The study explicitly addresses the ongoing statistical concerns in firm growth models such as sample censoring, regression to the mean, and unobserved heterogeneity. Our empirical results indicate that firm growth decreases with size. Smaller firms have faster rates of growth than larger firms, even after compensating for their higher attrition rates. The negative relation between age and growth predicted by the learning model is found to apply only to younger firms. Labor productivity affects firm growth positively, which indicates that there is a market selection process at work during the period of economic reforms in Ethiopia.
