TOÀN VĂN: THE IMPACT OF FDI SPILLOVERS ON THE PRODUCTIVITY OF DOMESTICALLY MANUFACTURING FIRMS AND AVERAGE WAGE IN VIETNAM – NCS. HUỲNH THỊ NGỌC HIỀN
Tóm tắt luận án:
The dissertation investigates the effects of FDI spillovers on domestic firms’ total factor productivity (period: 2011-2015; 385,976 observations) and recipient country’s average wage (period: 2007-2015; 693,720 observations) using a large unbalanced panel data of Vietnamese manufacturing enterprises. The econometric models are conducted using the fixed-effect model (FEM) as recommended by the Hausman test. The issue relating to biased TFP estimation is overcome by the use of the Olley-Pakes (OP) methodology. Further, firm heterogeneities are explored as moderating variables to reflect different levels of FDI spillover effects on productivity. First, the results indicate that the horizontal and forward spillovers associated with FDI presence in Vietnam have overwhelming negative impacts on domestic firms’ TFP. In contrast, the greater the effect of backward spillover is, the higher the productivity local firms can reach. Second, human capital is found as a facilitator for productivity spillovers from foreign firms to domestic firms. Third, a negative horizontal spillover effect and a positive backward spillover effect on the domestic firm’s TFP is impressively improved with the movement of technology gap from the bottom 25th percentile to the middle 25th -75th percentile. Fourth, it is found that FDI spillovers in both vertical and horizontal channels do not occur at the bottom 25th percentile of financial development while the effect of backward spillovers on firm productivity is significantly enhanced with a higher level of financial development. Fifth, although the relationship between all three FDI spillover channels and TFP varies significantly across regions, it doesn’t mean greater spillover effects as a result of higher FDI concentration. Finally, the overall effect of FDI on the average wage in Vietnam is significantly positive, except for domestic private firms. Besides, this research still has certain limitations such as not controlling the impact of macro factors, unable to access more balanced panel data for better measurements and additional methods with instrument variables.
