This paper re-examines the link between firm size and exports. The new theories of international trade emphasize firm heterogeneity as the theoretical basis of export behavior. In the context of this heterogeneity, this paper uses the quantile regression methodology to analyze the effects of firm size on firm export propensity (percentage of exported sales). The paper confirms the existence of a positive relationship between firm size and export propensity but finds that the conventional estimates of the elasticity of export propensity with respect to firm size on the average of the export propensities’ distribution underestimate the effect at the bottom of the distribution and overestimate the effect on the rest. Consequently, policies aimed at increasing exports should focus their efforts on increasing the size of those firms with a lower export propensity.

重新评估企业规模与出口之间的联系

本文重新审查了企业规模与出口之间的联系。国际贸易的新理论强调企业异质性是出口行为的理论基础。在这种异质性的背景下，本文使用分位数回归方法来分析企业规模对企业出口倾向（出口销售百分比）的影响。该论文证实了企业规模与出口倾向之间存在正相关关系，但发现传统的出口倾向相对于企业规模的弹性估计基于出口倾向分布的平均值低估了分布底部的影响。并高估了其余的影响。所以，
