Abstract
Foregin Direct Investment's (FDI's) contribution to growth has been a controversial topic in economic literature and appears to be country specific. In this article, we use time-varying coefficients in an augmented production function and let FDI indirectly affect Gross domestic product growth through labour productivity. This approach creates built-in heteroskedasticity, so the feasible generalized least square estimation is employed. The results show that FDI has significant and positive effect on labour productivity and economic growth in Vietnam, but the effect is not equally distributed among economic sectors.
