Efficient mobility is an essential driving force for the development of cross-border (CB) regions. The different settings and visions of neighbouring CB entities may lead to unsatisfactory transport connections across the border. This case study of a CB connection focuses on this issue and highlights, by means of a comparative analysis, how the differences in six perspectives (the economic context; urban and regional planning in Belgium and the Netherlands; the structure of the rail network; barriers in the exploitation of the railway; the current travel demand by rail; and the governance, public planning and policy context) lead to an unsatisfactory rail connection between Liège (Belgium) and Maastricht (the Netherlands). Based on the results of the analysis, we suggest reinforcing cross-mobility connections through several tools such as (i) the development of a common governance, by including economic and social stakeholders; (ii) the development of joint technical projects in relation to the infrastructure, communication systems and the rolling stock; and (iii) the strengthening of flows between the two sides of the border, especially the homework flows.

Research on regional innovation systems suffers from a lack of clarity concerning the spatial structure of these systems. In order to clarify this issue, we test empirically, through data on R&D projects developed by the Walloon competitiveness clusters, the theoretical assumption according to which the probability that two actors collaborate to innovate is correlated to the spatial distance separating them. Our analyses use the differentiation between the logics of "local buzz" and "global pipelines" formulated by the model of H. Bathelt et al. (2004). As our results highlight the structuring character of the regional level, we propose an improvement of this model by supplementing it with a reference to the "regional pipelines" logic. It also appears from our results that the relations between partners of R&D projects are particularly intense when the spatial distance between them is below 10 km, which is a mark of a significant "local buzz" dynamic.

En Belgique, nombreux sont ceux qui ont été confrontés au télétravail intensif suite à la crise de la Covid-19. À partir de l'analyse de données individuelles de l'Enquête sur les Forces de Travail, notre recherche s'est attachée à approfondir les connaissances sur la propension au télétravail avant cette crise, en Belgique et à Bruxelles. Pour ce faire, nous avons étudié les profils types de télétravailleurs, en distinguant télétravail intensif et à temps partiel, et leur localisation. Nos résultats mettent en évidence l'impact de plusieurs facteurs sur le télétravail, en ce compris la profession et la distance domicile -lieu de travail. Nos conclusions mettent ces résultats en perspective au regard du contexte de la pandémie et de l'impact potentiel du télétravail sur l'attractivité de Bruxelles. À travers cet article, nous plaidons pour une meilleure prise en compte de l'expansion des pratiques de télétravail dans les politiques de développement urbain.
