英文文献摘要：
This paper examines the relationship between countries??? bilateral trade with the United States that is not due to gravity (non-gravity trade) and the distribution of income within countries. In countries where only a small share of the population are educated, an increase in non-gravity trade is associated with a significant increase in income inequality. As education of the population increases the correlation between non-gravity trade and income inequality becomes smaller. Non-gravity trade has no significant effect on income inequality in countries that are world leaders in education.

本文研究了国家之间的关系，即与美国的非重力双边贸易(非重力贸易)和国家内部的收入分配之间的关系。在只有一小部分人口受过教育的国家，非重力贸易的增加与收入不平等的显著加剧有关。随着人口受教育程度的提高，非重力贸易与收入不平等之间的相关性变得更小。非重力贸易对世界教育领先国家的收入不平等没有显著影响。
