随着近年来各国开放程度的逐步加深与收入差距的持续扩大,对开放条件下收入不平等的研究成为国际经济学领域的热点。文章从传导机制的角度对贸易与收入差距关系的研究作一理论回顾,贸易通过要素价格、需求偏好、技术进步和弹性劳动力市场等渠道影响收入差距。大多研究都秉承经典HO定理的逻辑基础,放松其相关假设条件并将研究对象微观化,认为开放可能导致收入差距扩大而不是降低它,如何运用上述机理分析中国贸易和收入差距的关系并通过教育、相关政策的变化等调节收入差距是后续的研究方向之一。
With the gradual deepening of the degree of opening up of various countries and the widening income gap in recent years, the study of income inequality under the open conditions has become a hot topic in the field of international economics. The article makes a theoretical review of the research on the relationship between trade and income disparity from the perspective of transmission mechanism. Trade affects income disparity through factors such as factor price, demand preference, technological progress and flexible labor market. Most researches hold the logical foundation of classical HO theorem, relax the relevant assumptions and micro-study the subject, think that opening up may lead to the income gap widening instead of reducing it. How to use the above-mentioned mechanism to analyze the relationship between trade and income disparity in China and through education , And other relevant policies to adjust the income gap is one of the follow-up research direction.
