The effect of export on prodưc of enterprises in Vietnam

The effect of internal factors showing the characteristics of each enterprise, the control variables on TFP, the labor productivity of enterprises are shown as follows:

The level of capital equipment per capita increases, the total factor productivity and labor productivity of the whole sample tend to be negative. The coefficient of external capital (vng) has negative value in most models, except for the full-model model that affects TFP and is statistically significant. Overall, the external capital source has a positive impact on the change of TEP. However, this source of capital has no effect on changing labor productivity. The age coefficient of an enterprise is positive, as the age of the enterprises increases, the total factor productivity and labor productivity also increase. Older enterprises often have productive capacity as well as efficient capital, facilitating the application or learning of high-tech technologies, thereby increasing productivity. Enterprises that grow to the top will tend to decrease.
