O presente estudo analisa as características urbanas, os elementos preexistentes condicionantes, e as potencialidades da região industrial ao longo da orla ferroviária da antiga Linha Santos-Jundiaí que abrange os distritos do Cambuci, Brás, Pari, Móoca, Ipiranga e Vila Prudente, do município de São Paulo, em uma perspectiva de reconhecê-la enquanto reserva urbana especial. Desta forma, investigase a lógica do capital subjacente à perda do \'valor-de-uso\' enquanto obsolescência produzida, e relacionada ao processo de substituição a outros usos. As modalidades de reprodução do espaço efetivam-se na região pelos investimentos do setor privado por meio de produtos imobiliários que negam a cidade. Do ponto de vista metodológico, foi realizado um levantamento bibliográfico e uma análise teórico-conceitual, incluindo um breve estudo de caso da Europa. Compreende também um levantamento de campo em São Paulo que focalizou na caracterização do uso e ocupação do solo e na obtenção de dados referentes à obsolescência e contaminação. À luz das análises levadas a efeito determinou-se que o conjunto das terras industriais constitui áreas de intrínseco valor urbano, argumenta-se a cerca do seu reconhecimento enquanto prerrogativa para definição de novos usos no âmbito da reconversão. / The study analyses the urban features, conditioning existing elements and potentiality of the industrial area along the old railway Santos - Jundiai including Cambuci, Brás, Pari, Móoca, Ipiranga e Vila Prudente districts of the municipality of Sao Paulo, aiming to qualify the area as an urban special reserve. In doing so, the study investigates the logic of capital underlying the loss in use value as produced obsolescence and related to the process of substitution for other land destination. Currently the re-production of the urban space in the area is achieved through private investments in the building sector, which generate products, that denied the city. Starting from a bibliographic research, the study assumes a conceptual and theoretical approach, develops an empiric analysis in Sao Paulo and includes European experiences, particularly in London (United Kingdom) and Turin (Italy). The field work in Sao Paulo focuses the different types of land uses and occupation and a data collection referred to the obsolescence and environmental pollution. The research highlights that the former industrial areas represent urban value land. It is argued for a formal recognition of the urban value as a precondition for a new use definition in the context of the reconversion process.

Construction socio-spatiale héritée du XIXe siècle ayant connu un déclin dans la seconde moitié du XXe siècle, les quartiers de gare centrale dans les villes occidentales sont un support récent et privilégié de l’action collective urbaine. Les projets urbains que ces gares cristallisent présentent des programmations récurrentes reposant sur la mixité fonctionnelle et une orientation tertiaire affirmée. Cette thèse interroge le retournement de valeur symbolique et économique de ces espaces autrefois dévalorisés et aujourd’hui prisés. Quelles sont les modalités de la fabrique urbaine, comment se noue l’interaction nécessaire entre des acteurs publics ne pouvant intervenir seuls sur ces secteurs fortement contraints (notamment techniquement), et des acteurs privés parfois réticents à s’engager sur des marchés qu’ils jugent risqués ? En adoptant une approche inductive et qualitative, ce travail de recherche analyse la conception et la mise en œuvre de deux projets urbains aux avancements contrastés en raison de leviers d’action ou, au contraire, de points de blocages différents, dans deux anciennes villes minières devant négocier le tournant de la désindustrialisation (Saint-Étienne et Liège). Au terme de l’analyse, l’hypothèse d’une valeur assurantielle de la gare dans ces projets urbains est validée : en tant que ferment métropolitain vecteur de fortes potentialités, la gare centrale desservie par un train à grande vitesse est la condition de possibilité permettant d’enclencher non seulement la décision des acteurs publics mais aussi celle des acteurs privés, au premier rang desquels les promoteurs immobiliers, acteurs clés à l’interface entre l’action publique et l’investissement privé / The railway station areas of the 19th Century were a reflection of the Industrial revolution. Following a period of decay after the Second World War, the urban renewal of these areas is now one of the main concerns of local governments in European cities. In addition to a new railway station served by high speed trains, these urban projects are often based on functional diversity, including a business district.This thesis addresses the reversal of urban value in these specific urban areas, exploring how they have moved from repelling to attractive places. How do public and private actors interact, when the former cannot act alone in places constrained by physical barriers due to a lack of funding, and the latter are not inclined to invest in what they consider to be risky places?Our approach is both inductive and qualitative. The comparison of two projects in French and Belgian shrinking cities (Saint-Etienne, near Lyons, and Liège, near Brussels) allows us to understand what the levers for action are, and conversely what the bottlenecks are that slow down the implementation of the urban project around the station.As the result of our analysis, the railway station appears to be a positive and necessary factor for the reversal of urban value in these areas. It is a kind of insurance – in the same way as metropolitan areas create potentiality in the productive economy – both for public actors, as the railway station facilitates their mobilisation, and private ones, especially property developers, who are key elements in the relationship between public action and private investment
