RESUMO: Este artigo analisa o comportamento das exportações como função da disponibilidade da infraestrutura de transporte e do nível de PIB per capita das microrregiões brasileiras em 2003. Para esse propósito, foi implementada preliminarmente uma análise exploratória de dados espaciais e, em uma etapa posterior, desenvolveu-se uma análise econométrico-espacial por meio da inclusão da defasagem espacial do termo de erro. Os resultados indicam que o crescimento econômico contribui de forma significativa para o desempenho exportador das microrregiões.
ABSTRACT: The export growth plays an important role in the economic development and the reduction of external vulnerability. This work analyzes the behavior of Brazilian exports in 2003 at the micro-regional level. Such an analysis evaluates the internal factors (GDP per capita and transport infrastructure) that influence the growth of the exports. To do so, an exploratory analysis of spatial data is preliminarily implemented. Further, spatial econometric analysis is developed by means of the inclusion of a spatially lagged of the error term. The main finding indicates that economic growth contributes significantly to microregions´exporting performance.
