Territorial Development and Cross-Border Cooperation: A Review of the Consequences of European INTERREG Policies on the Spanish–French Border (2007–2020)

Territorial cohesion policies are a priority for the European Union. For over thirty years, they have aimed not only to provide greater social and economic development across all European space, but also to contribute to balancing g internal social and economic inequalities. On the other hand, European institutions have adopted regional scale as the optimal to achieve this broad goal. Consequently, the ability of these policies to solve the problems faced by some of these regions has been one of the most widely researched areas in numerous scientific disciplines. This article aims to assess the impact, over a fifteen-year perspective, of cooperation funds focusing on a specific area, the cross-border, and, in particular, the border area separating Spain and France. Specifically, the analyses of data from operative programmes IV and V of the INTERREG-A projects produces contradictory results. While the aim of European institutions was to use the European Territorial Cooperation instrument to achieve a greater, better real impact of funds in cross-border areas, and to progress towards territorial cohesion, the results show that, conversely, they have largely contributed to reinforcing unequal development. In the analysed border, the dynamics are an increasing distance between the more and less developed areas in the direct border space, and a privilege of urban areas, even if they are far from the borderline. A relevant conclusion of the text is that these unexpected results are partly a consequence of the design of the European programmes.
