Do African Manufacturing Firms Learn from Exporting?
利用四个非洲国家制造业企业面板数据，同时估计生产函数和出口回归，发现出口能显著提升企业效率，即存在“出口中学习”效应，对非洲制造业出口导向政策有启示。
We use firm-level panel data for the manufacturing sector in four African countries to investigate whether exporting impacts on efficiency, and whether efficient firms self-select into the export market. Based on simultaneous estimation of a production function and an export regression, our preferred results indicate significant efficiency gains from exporting, which can be interpreted as learning by exporting. We show that modelling unobserved heterogeneity by a flexible approach is important for deriving this conclusion. A policy implication of our results is that Africa would gain from orientating its manufacturing sector towards exporting. © 2004 Taylor and Francis Ltd.
