    Abstract

    Uma melhoria da infra-estrutura e da logística, ao integrar a produção e os negócios entre as diferentes regiões ou países, reduz os custos do comércio e promove a riqueza. No entanto, as análises sobre o relacionamento da infra-estrutura com o comércio internacional tem tido muito mais atenção do que em nível regional ou interestadual. Assim, o objetivo desse estudo foi levantar e quantificar o relacionamento existente entre a disponibilidade dos serviços de infra-estrutura e o volume de comércio entre os estados brasileiros. Criou-se um indicador da infra-estrutura existente nos diferentes estados, que foi relacionado ao fluxo comercial entre eles. O estado de São Paulo apresentou os maiores valores, aparecendo com indicadores máximos, em seis das onze variáveis de infra-estrutura consideradas. O modelo de gravidade, proposto para a análise, apresentou estimativas coerentes e significativas para as variáveis incluídas. A variável PIB do estado importador foi a mais importante para explicar os fluxos de exportação estaduais. O indicador utilizado para medir os efeitos da infra-estrutura, mostrou-se também, importante, indicando aumentos mais que proporcionais nas exportações de bens entre os estados brasileiros (1,18%). Contudo, conclui-se que, se os investimentos em infra-estrutura dos estados mais pobres, continuarem sendo inferiores aos dos estados mais ricos, a participação dos mesmos na produção e comércio nacional continuará a declinar.---------------------------------------------An improvement on infrastructure and logistics, by integrating production and businesses among different regions or countries, reduces costs of trade and promotes wealth. However, the relationship of infrastructure with international trade, have had much more attention than the relationship of infrastructure with trade at regional or interstate level. So, the objective of this study was to quantify the relationship between the existent infrastructure services and the trade volume among the Brazilian states. It was created an indicator of the existent infrastructure, in different states, that was related to the commercial flow among them. The state of São Paulo presented the largest values, showing maximum infrastructure indicators, in six out of eleven variables considered. The gravity model, proposed for the analysis, presented coherent and significant estimates for the included variables. GDP from the importer state was the most important variable to explain the export flows. The indicator used to measure the effects of infrastructure, was also important, indicating larger increases on exports of goods among the Brazilian states (1.18%). As a conclusion, it can be said that, if investments on infrastructure at the poorest states of Brazil, continue to lag that of the richest states, their share of the production and national trade will continue to fall.
