本文在对有关理论进行梳理的基础上,搜集1991～2011年我国对外直接投资额、进口总额和出口总额,进行E-G协整检验,建立误差修正模型,对我国对外直接投资与进出口贸易之间的关系进行了实证分析。研究结果表明,我国对外直接投资对进出口贸易的影响,短期内为替代效应,长期则为互补效应。 On the basis of sorting out the relevant theories, this paper collects the total amount of foreign direct investment, the total amount of imports and the total amount of exports from 1991 to 2011, carries out the EG cointegration test, establishes the error correction model, and makes a comparison between China’s foreign direct investment and import and export trade The relationship between the empirical analysis. The results show that the impact of China’s foreign direct investment on the import and export trade in the short term is the substitution effect and the long-term effect is the complementary effect.
