Les activités logistiques sont des leviers de la performance des systèmes productifs ainsi que d’importants générateurs d’emplois. Néanmoins, par les flux qu’elles impliquent ainsi que par les fixités qui la soutiennent (infrastructures, équipements, bâtiments, etc.), ces activités sont des sources de nuisances pour les territoires. Afin d’attirer les activités logistiques tout en limitant leurs nuisances, les acteurs publics – particulièrement locaux – y déclinent un certain nombre d’outils de régulation. Une politique publique est particulièrement mobilisée à cet effet, encouragée par l’exigence de report modal qu’implique le nouveau référentiel guidant l’action publique fondé sur la durabilité : la zone d’activité logistique, zone économique avec ses équipements propres aménagée en vue d’accueillir des activités logistiques.Cette thèse s’intéresse à l’articulation entre ces politiques d’aménagement et les dynamiques de développement économique des territoires. La première partie de ce travail met notamment en évidence trois rôles distincts que peuvent jouer ces zones d’activité logistique, deux rôles externes directs et indirects, et un rôle interne. Par la mobilisation de différentes méthodes et données originales, la deuxième partie de ce travail vise à tester la validité empirique de ces rôles. Le résultat majeur de ce travail de thèse est qu’en raison de la nature de l’activité logistique – qui s’inscrit dans des chaînes et des réseaux élargis – les retombées économiques indirectes imputables aux zones d’activité logistique sont relativement faibles / Logistics activities are fundamental leverages for the productive systems’ efficiency, but also create a lot of jobs. However, logistics activities induce negative externalities: first, by the flows created by these activities, then by the facilities supporting it (infrastructures, equipment, buildings, etc.). To attract logistics activities, while reducing negative externalities, local public authorities use a certain number of regulatory tools. To that extent, a public policy is mostly used, pushed forward by modal report necessity linked with sustainable development: the logistics center, which is an area equipped in order to host logistics activities.This thesis focuses on the articulation between planning policies and regional economic development. The first part brings to light different roles played by logistics centers: two external roles, direct and indirect, and one internal. By using original methods and data, the second part of this thesis aims to test the validity of these different roles. The major result of this work is that by nature of logistics activities – which take part in enlarged chains and networks – the wider economic impacts of logistics centers are low

Relying on the Export Base Theory, which says that expansion of exports has a multiplier effect on the activities of domestic non-exporting, impacting the tertiary sector of the local economy by creating demand for services and increasing income levels and employment of the population, this dissertation seeks to characterize the trade in Sergipe and show criteria that can support strategies to promote exports. Therefore, initially characterized the importance of foreign trade to economic growth and the factors relevant to its expansion. To this end, it approaches the theoretical aspects related to the Theory of Export Base and the Economic Base, and characterized by analysis of patterns of international trade, what are the main determinants of exports at the firm. Next, in order to extract lessons, includes examples of countries that have adopted an export-oriented model as a strategy for economic growth and achieved success, highlighting the case of Italy, South Korea and Mexico. In addition, we carried out a characterization of the main actions and instruments that, in general, have been developed in Brazil, considering the increasing export activity. Finally, it is a specific analysis for the State of Sergipe, which is divided into two main parts. The first part takes place a characterization of the economy, pointing out which are the major economic sectors and what the main features of its foreign trade, especially those related to exports. In the second part, suggestions are based on the theory of comparative advantage, the products of Sergipe with higher export potential. The results indicate that a total of 99 items exported by Sergipe in 2007, 35 have no export potential, 8 are dynamic and, 56 have export potential. / Fundamentando-se na Teoria da Base Exportadora, a qual preconiza que a expansão das exportações exerce um efeito multiplicador sobre as atividades do mercado interno não exportador, impactando no setor terciário da economia local por meio da criação de demanda por serviços e, por conta disso, incrementando os níveis de renda e de emprego da população, esta dissertação procura caracterizar o comércio exterior em Sergipe e apresentar critérios que possam subsidiar estratégias de promoção de exportações. Para tanto, caracteriza-se inicialmente a importância das vendas externas para o crescimento econômico e quais os fatores relevantes para sua expansão. Com este intuito, abordam-se no referencial teórico os aspectos referentes à Teoria da Base Exportadora e da Base Econômica, além de assinalar, através da análise dos modelos de comércio internacional, quais seriam os principais determinantes para as exportações, ao nível da firma. Na seqüência, com o objetivo de se extrair lições, apresentam-se exemplos de países que adotaram um modelo voltado para exportação como estratégia de crescimento econômico e que obtiveram êxito, destacando-se o caso da Itália, da Coréia do Sul e do México. Além disso, realiza-se uma caracterização das principais ações e instrumentos que, no âmbito geral, vêm sendo desenvolvidas no Brasil, tendo em vista o incremento da atividade exportadora. Por fim, faz-se uma análise específica para o Estado de Sergipe, sendo esta dividida em duas partes principais. Na primeira realizase uma caracterização econômica do Estado apontando quais são os seus principais setores econômicos e quais as principais características do seu comércio exterior, sobretudo, àquelas relacionadas às exportações. Na segunda parte, apontam-se, com base na Teoria das Vantagens Comparativas, quais os produtos de Sergipe que apresentam maior potencial exportador. Os resultados indicam que, de um total de 99 itens exportados por Sergipe em 2007, 35 não apresentam potencial exportador, 8 são dinâmicos e, 56 apresentam potencial exportador.
