尽管从贸易理论,上来说学者们对投资和贸易之间存在着互补关系还是替代关系存在着争论,但是实证分析发现,1991-2009年间,台湾对大陆的直接投资带动了贸易的增长,存在着互补效应。而且格兰杰因果检验表明,台湾自大陆进口与向大陆出口之间存在双向格兰杰因果关系。 Although there is debate on whether there is a complementary or alternative relationship between investment and trade from the perspective of trade theory, empirical analysis shows that direct investment in the mainland by Taiwan from 1991 to 2009 led to the growth of trade and the existence of Complementary effect. And Granger causality test shows that there is a two-way Granger causality between Taiwan’s imports from the mainland and its exports to the mainland.
