Abstract 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.
