[en] Access to information on public buyers and selected service providers has been enhanced by the recent release of public procurement data at the European level. After being "cleaned" and geo-referenced, the European Tenders Electronic Daily (TED) database enabled the creation of a France scaled database: the French Open Public Procurement Award (FOPPA) database. This database enables a novel exploration of interactions between spatial units at different scales. It allows for the identification of market participants, their partners, and the types of contracts, providing a basis for analyzing and understanding these relationships. In this article, we highlight the analytical potential of the FOPPA database by examining interactions in public procurement at regional, departmental, and municipal levels. We assess the ratio of service providers to service seekers as an indicator of the economic fabric's strength within each territorial unit. For exploratory purposes, our analysis of relationship intensity focuses on the role of geographic and topological distances between contracted spatial units. Findings underscore the primacy of spatial contiguity over geometric distance in shaping market geography. Additionally, the spatial dynamics of public procurement appear to vary depending on the type of contract (supplies, services, or works). Finally, we use data on works contracts in the Vaucluse (France) at the municipal level to illustrate how FOPPA data can offer a novel perspective on the relevance of territorial divisions.In this article, we illustrate some of the scope for analysis offered by the FOPPA database, by producing analyses of interactions, through the prism of public procurement, at regional, departmental, and municipal levels. We analyze the ratio of service providers to service seekers as an indicator of the strength of the economic fabric of each territorial unit. For heuristic purposes, the explanation of the intensity of the relationships is essentially limited to exploring the role of the distances in kilometers and topology between the contracted spatial units and shows the primacy of the contiguity of the spatial units over their geometric distance as an explanatory factor of the geography of the markets. It also appears that the spatial logic of public procurement differs according to the type of contract (supplies, services or works). Lastly, data on works contracts in the Vaucluse (France) at the municipal level are used to illustrate the possibility of using FOPPA data to study the relevance of territorial divisions from an original angle.

[es] La reciente apertura de los datos sobre contratación pública a escala europea permite acceder a información sobre la oferta pública y los proveedores de servicios. La limpieza y georreferenciación de la base de datos Tenders Electronic Daily (TED) que contiene información referente a la contratación pública, permite generar y poner a disposición tal contenido a escala francesa constituyendo así la base de datos French Open Public Procurement Award Notices (FOPPA). Tal base posibilita explorar de forma inédita las interacciones entre unidades espaciales a diferentes escalas, identificando así a los actores y socios implicados en los contratos, como la naturaleza de estos últimos, todos los anteriores con el fin de analizar y explicar estas relaciones. Este artículo, expresa las virtudes que ofrece la base de datos FOPPA, a partir de un análisis esencialmente descriptivo de tales interacciones, a través del prisma de la contratación pública a escala regional, departamental y municipal. En particular, se analizan las relaciones de la oferta pública con proveedores de servicios como un posible indicador de la solidez del tejido económico de las unidades espaciales. De manera exploratoria, el análisis de la intensidad de las relaciones se limita a explorar el papel de las distancias euclidianas y topológicas entre las unidades espaciales asociadas. Los resultados expresan la primacía de la contigüidad de las unidades espaciales sobre su distancia geométrica como factor explicativo de la geografía de los mercados. Además, permite comprender la lógica espacial de contratación, la cual difiere según se trate de contratos de suministros, servicios o/u obras. Finalmente, se aplica un caso de estudio para el departamento de Vaucluse a escala municipal a partir de los contratos de obras para ilustrar la posibilidad de esta base FOPPA para estudiar la pertinencia de las rupturas territoriales.
