This study investigates how industries with different patterns of firm heterogeneity distribute across countries by developing a three-sector general-equilibrium model. We show that the larger country is more specialized in the industry with heterogeneous (homogeneous) firms when trade costs are low (high) and that an increase in the inter-industry difference in firm heterogeneity fosters the larger country’s degree of specialization in the industry with heterogeneous firms. We also disclose the wage inequality and trade patterns across countries and show how they respond to trade liberalization.

行业间贸易和异构企业：国家规模很重要

这项研究通过建立三部门一般均衡模型，研究了具有不同公司异质性模式的行业如何在国家间分布。我们表明，在贸易成本低（高）的情况下，较大的国家对具有异质（均质）公司的行业更加专业，并且企业异质性的行业间差异的增加促进了较大国家在以下方面的专业化程度：异构公司。我们还披露了各国之间的工资不平等和贸易模式，并展示了它们如何应对贸易自由化。
