摘要
通过1994至2007年我国主要对外经济往来国的双边贸易流及投资数据,考察了我国农业对外贸易与对外投资合作的关联度及相互影响,通过异方差处理的重力模型估计,发现使用FGLS与MLE方法修正后的重力模型优于面板模型。结论显示外商对华农业的直接投资与我国对外直接投资对农业贸易往来表现出刚好相反的作用。前者为相互促进的互补关系,后者则是一种相互抑制的替代作用。
This study analyzed the relationship between international trade and FDI in/out flows in agricultural area of China based the data from 1994—2007.The findings show the classical regression model FGLS and MLE with cross-sectional heteroscedasticity is more appropriate for describing the selected gravity model than panel data model.Moreover,the results show that FDI inflows and outflows perform exactly opposite effects to China＇s international agricultural trade.The former acts complementary positively and the latter is substitutes negatively.
