技能型技术进步、南北贸易与工资不平衡

本文试图将技能型技术进步与产业内贸易置于一个框架中对工资不平衡现象进行理论解释。自由贸易通过促使发达国家产品质量阶梯提升型的技术进步而加剧了该国的工资不平衡程度;同时,自由贸易通过促使发展中国家产品种类数增加型的技术进步而加剧了该国的工资不平衡程度。南北贸易在拉大相对工资差距的同时促进了技能型技术进步。

Skill-biased Technical Progress,North-south Trade and Wage Inequality

This paper tries to incorporate skill-biased technological change and north-south trade into one comprehensive framework and analyze the principle governing the change in relative wage of the skilled labor factor. Intra-industry trade is a potentially important explanation for the increase in the wage inequality in the developed countries through the product quality upgrading. For the developing countries, the rising inequality results from intra-industry trade through increasing the number of differential products. North-South Trade has much the same impact on wage inequality as does skill-biased technical progress.
