ABSTRACT (cross-border co-operation, economic competition and complementarity, French-Belgian metropolis of Lille) (Ieper, Kortrijk, Lille, Mouscron, Roeselare, Tournai) At the request of the Cross-Border Workshop, Wim Vanhaverbeke, Jean-François Stevens, Henri Capron and André Delpont analyse the challenges with regard to development and economic integration which the areas comprising the cross-border metropolis of Lille have to face. On the basis of this analysis, the Workshop puts forward the following priorities : • the cross-border situation regarded as an asset, • becoming a metropolis and a centre of technology, • observation, communication and networking. The development of a cross-border job market is both a condition for and a surplus value of economic integration. |
