In this research, we estimate a gravity equation augmented with technological innovation and transport infrastructure variables in order to analyse the impact of these variables on international trade. According to our results, investing in transport infrastructure and technological innovation leads to the improvement and maintenance of the level of competitiveness. Moreover, our results support the hypothesis that countries tend to trade more when they are ¿closer¿ from a technological point of view and that the development of information technology has lowered the effect of geography on trade. En este trabajo, estimamos un modelo de gravedad ampliado con variables de innovación tecnológica y de infraestructura de transporte con el fin de analizar el impacto de estas variables sobre el comercio internacional. Según los resultados obtenidos, invertir en infraestructuras de transporte y en innovación tecnológica mejora y mantiene los niveles de competitividad alcanzados en los países. Nuestros resultados, también apoyan la hipótesis de que los países comercian más cuanto más similares son desde un punto de vista tecnológico y que el desarrollo de las tecnologías de la información ha reducido el efecto negativo de la distancia geográfica sobre el comercio internacional.
