近年来,随着中国对外开放程度的提高,中美贸易额逐年上升,由于美国贸易逆差不断加剧,为了保护自身利益,美国企业不断利用337条款来打击外国竞争者。从2003年开始,中国已经成为337条款申诉的最大受害国。因而,对于相关案例的深入研究是十分有必要的。本文主要通过对337调查对常州出口企业的影响现状及存在原因的研究,探索找出切实可行的解决办法和应对措施,切实减少企业的损失。 In recent years, with the improvement of China's opening up to the outside world, the trade volume between China and the United States has been on the rise year by year. Due to the ever-increasing trade deficit in the United States, U.S. companies continue to use Section 337 to fight against foreign competitors in order to protect their own interests. Since 2003, China has become the biggest victim of Section 337 complaints. Therefore, in-depth study of the relevant cases is very necessary. This paper studies the impact of Section 337 investigation on Changzhou export enterprises and its causes, explores feasible solutions and countermeasures, and effectively reduces the losses of enterprises.
