多产品出口企业相关问题的研究进展

The Review of Issues Concerning Multi-Product Exporters

近期越来越多的国际贸易文献开始关注多产品企业的出口行为。从以下三个方面归纳和评述已有的研究成果:多产品企业的产品范围、多产品企业贸易的二元边际以及产品转换。结果发现出口贸易中许多企业出口不止一种产品,出口集中在少数规模较大的出口商而且产品转换行为非常频繁、普遍和显著。通过对已有文献的总结和评述,在此基础上得出了启示并指出了国内研究的不足。

Recently more and more international trade papers have begun to pay attention to the export behavior of multi-product firms.This paper sorts out the relevant literatures from three aspects:multi-product firm’s product scope;extensive and intensive margins of multi-product trade and multi-product firms’ product switching.It is found that exports are concentrated among few but large-firms and those firms typically export more than a single product.The product switching in multi-product exporters is very frequent,widespread and prominent.Based on the review of these literatures,some inspirations and directions for future research have been drawn.
