战后,在关贸总协定的主持下,各国进行了8轮艰苦的谈判,关税壁垒的作用已被大大削弱,相形之下,非关税壁垒日趋成为贸易保护主义的重要手段。在非关税壁垒中,技术壁垒成为引人注目的焦点。本文将重点探讨技术壁垒的成因及其特点,从分析中不难看出,尽管技术壁垒阻碍了国际贸易的顺利发展,但是它的存在有其合理性的一面。 After the war, under the auspices of the General Agreement on Tariffs and Trade, countries conducted eight rounds of arduous negotiations. The role of tariff barriers has been greatly weakened. By contrast, non-tariff barriers are increasingly becoming an important means of trade protectionism. In non-tariff barriers, technical barriers have become the focus of attention. This article will focus on the causes of the technical barriers and their characteristics. It is not difficult to see from the analysis that although technical barriers hinder the smooth development of international trade, its existence has its rationality.
