基于企业异质性的出口自选择行为研究综述

近年来，国际贸易理论的研究经历了一个革命性的变化，学者们开始运用企业层面的微观数据分析出口行为和生产力之间的关系，并提出了出口的自选择假说和学习效应假说。文章对这一领域截至目前的理论和实证文献进行梳理和总结，并展望未来的研究前景。

A Survey of Export Self-selection based on Firm Heterogeneity

In recent years, researches on international trade have experienced a revolutionary change. Economists began to use micro data on plants and firms to investigate the linkage between export and productivity and thereby putting forward two hypotheses: self-selection and learning by exporting. This paper attempts to review the existing theoretical and empirical literatures until now and summarizes what we can learn from them to throw light on future work in this area.
