Is foreign direct investment productive? A case study of the regions of Vietnam

By making use of a recently released dataset that covers a large number of manufacturing firms over the period 2000–2005, this paper examines the impact of foreign direct investment (FDI) and FDI generated spillovers on total factor productivity (TFP) in eight regions of Vietnam. Unlike most existing studies, this paper focuses on the impact of spillovers that take place through both horizontal and vertical linkages. The results presented in this paper suggest that the impact of FDI spillovers on TFP varies considerably across regions. FDI spillovers generate a strong positive impact on TFP through backward linkages only in Red River Delta, South Central Coast, South East and Mekong River Delta while in other regions the impact is negative and mostly insignificant. The paper also examines the impact of the absorptive capacity on TFP growth in each of the eight geographical regions.
