Ce livre collectif s'appuie sur l'atelier pluridisciplinaire de jeunes chercheurs qui s'est tenu Louvain-la-Neuve les 11-13 juin 2003. Il se penche sur des cas concrets dans les secteurs du transport routier, de l'informatique et des t l communications des ann es 1950 aux ann es 1980. Il tudie la naissance difficile et conflictuelle d'une expertise des acteurs sur le terrain nouveau de l'Europe int gr e. Tandis que les entreprises d couvrent l'importance d'agir sur le processus de d cision en marche, elles se voient attribuer une place dans cette concertation participative. Ce nouveau r le n cessite l'accumulation de comp tences techniques largies et la multiplication de contacts avec les autres acteurs. Ensemble, ils participent la d limitation du cadre communautaire ( travers l' laboration des normes techniques, l'harmonisation de la fiscalit , la r gulation des aides d' tat, etc.) et entendent y d fendre au mieux leurs int r ts. Cela peut tre l'occasion d'oppositions frontales, souvent difficiles contourner. De nouveaux apprentissages sont alors n cessaires pour t cher d'avancer dans l'harmonisation communautaire.
This collection of papers derives from the multidisciplinary workshop of young researchers which took place in Louvain-la-Neuve on 11-13 June 2003. It is based on actual case studies in the sectors of transport, data-processing and telecommunications between the 1950s and the 1980s. It analyses the long and difficult process for those involved in building expertise in the new field of an integrated Europe. At the same time as firms discovered the importance of influencing the decision-making process at work, they were given a place in this participative process. This new role implies the accumulation of enlarged technical competencies and the multiplication of contacts with other economic actors. Together, they have taken part in the demarcation of the Community framework, through the elaboration of technical standards, tax harmonisation, state aids regulation, and so on, and have defended their interests in this framework as best they could. This could provoke strong opposition, which was difficult to overcome. In this case, a process of learning and understanding was necessary on both sides in order to advance Community harmonisation.
