In this dissertation, we use unique data set to examine bilateral Foreign Direct Investments (FDI) data and find determinant factors of bilateral FDI activities. In Chapter 1, we examine the relationships among the bilateral annual non-aggregated national level FDI, all levels of Economic Integration Agreements (EIAs) and political turnovers happened in both FDI exporting countries and FDI importing countries. In Chapter 2, we test the Tariff-Jumping FDI hypothesis and Export-Oriented FDI hypothesis. In Chapter 3, we examine and determine the key determinant factors of Cross-Hauling FDI status.
