The subject proposed concerns the geography of the retail sector and consumption in a specific type of area: the double border areas on either side of each of the dyads in the Three Borders Triangle (Belgium, France, Luxembourg). The article focuses on the retail chains that have become dominant in these three countries, by studying:
firstly, the spatial development strategies pursued by the management of these groups in terms of locations in the border areas,
secondly, the adaptations to certain national directives made by the managers of outlets situated in areas characterised by fierce competition due to the discontinuities generated by the border.
