本文在回顾了国内外国际贸易与国内贸易之间关系理论和文献的基础上,以现有的统计数据,运用协整技术和Granger因果分析方法对我国国际贸易与国内贸易的关系展开了实证研究。研究表明,国际贸易与国内贸易之间存在着协整关系,但是二者之间不存在因果关系,这主要由于是我国国内市场分割造成的。 Based on the review of the theory and literature on the relationship between international trade and domestic trade both at home and abroad, this paper uses empirical statistics, using cointegration techniques and Granger causality analysis methods to conduct empirical research on the relationship between China’s international trade and domestic trade. . Research shows that there is a co-integration relationship between international trade and domestic trade, but there is no causal relationship between the two. This is mainly due to the division of China’s domestic market.
