Infra-estrutura de transpporte: uma análise através de modelos aplicados de equilíbrio geral inter-regional

This work analyses the impacts of the implementation of transportation infrastructure projects over the regional and national economic growth. The methodological framework consists in the integration of a transportation model with an interregional applied general equilibrium model. The simulations are conducted to access the impacts on the national and regional economies due to the duplication of the federal highway BR-101. The improvement of BR-101, one of the most important road linking between the regions Northeast, Southeastern and South of the country, points with respect to difficult situation of the Northeast region in relation to the too much Brazilian regions. The results of long run show a relative loss northeast in relation to the regions most dynamic of the country, when the variation of the GDP is considered. That is, the infrastructure improvement in an interregional context, imply that more dynamic regions attract for itself the benefits of one better flow of commerce. In this sense, the northeast dependence with respect to the intraregional trade is extended with the improvement of the accessibility between regions
