本文回顾了最近关于异质企业和贸易的理论文献，这些文献强调企业选择进入国际市场和企业之间的资源重新配置。我们讨论了推动这项研究的实证挑战及其与传统贸易理论的关系。我们研究了企业异质性对比较优势、市场规模、总贸易、贸易带来的福利收益以及贸易与收入分配之间关系的影响。尽管许多研究考察了企业生产率对贸易自由化的内生反应，但企业内部组织建模和企业异质性的起源仍然是正在进行的研究的有趣领域。
This article reviews the recent theoretical literature on heterogeneous firms and trade, which emphasizes firm selection into international markets and reallocations of resources across firms. We discuss the empirical challenges that motivated this research and its relationship to traditional trade theories. We examine the implications of firm heterogeneity for comparative advantage, market size, aggregate trade, the welfare gains from trade, and the relationship between trade and income distribution. Although a number of studies examine the endogenous response of firm productivity to trade liberalization, modeling internal firm organization and the origins of firm heterogeneity remain interesting areas of ongoing research.
