This study tries to examine the influence of foreign direct investment (FDI) on the total factor productivity (TFP) convergence of the manufacturing industries in Vietnamese provinces. We find that the convergence rates estimated using spatial lag and error models are larger than those implied by panel data models that do not consider spatial dependence. The spatial dependence of TFP growth in the provinces is due to geographical TFP and FDI spillovers. Our findings indicate that studies on the convergence rate of regions should check for spatial dependence.

外商直接投资能否促进转型经济中制造业的空间全要素生产率趋同？来自越南的经验方法

本研究试图检验外国直接投资 (FDI) 对越南各省制造业全要素生产率 (TFP) 收敛的影响。我们发现使用空间滞后和误差模型估计的收敛速度大于不考虑空间依赖性的面板数据模型所暗示的收敛速度。各省 TFP 增长的空间依赖性是由于地理 TFP 和 FDI 溢出。我们的研究结果表明，对区域收敛速度的研究应该检查空间依赖性。
