本文根据协整理论和格兰杰因果检验方法,对我国遭受33调查的数量和美国统计的中国对美出口增长量进行了实证分析。研究表明,我国遭受337调查的数量与美国统计的中国对美国的出口增长量之间存在长期稳定的均衡关系,同时美方统计的中国对美国的出口增长量是中国遭受337调查的格兰杰原因。 Based on the cointegration theory and Granger causality test, this paper analyzes the number of China’s 33 investigations and the growth of China’s export to the United States in the United States. The study shows that there is a long-term stable equilibrium between the number of 337 investigations that China is subjected to and the U.S.-derived China’s export growth to the United States. Meanwhile, the U.S.-derived China’s export growth to the United States is Granger’s reason for China’s 337 investigation .
