As part of the revision of the overall plan for the Île-de-France, a study of the "deindustrialization" of the Paris region was carried out by a team of consultants for the regional directorate of the Ministry of Infrastructure. This article highlights the main findings.
The authors first outline the changes observed in France and in the Paris region over the last 30 years. This overview reveals, basically, that manufacturing employment has fallen sharply and, in spite of major improvements in productivity, the share of the national value added contributed by firms in the Île-de-France has fallen. By contrast, it appears that commercial services have expanded and have largely offset the decline in the manufacturing sector in the region.
Having given details of this finding, the authors suggest two possible scenarios based on a survey they conducted of 40 decision-makers.
The first scenario relates to firms which intend to "act so as to optimize costs and rationalize their activities", while the second relates to those that focus rather on developing certain specialties. The authors argue that, in any case, the image of Paris and its region has a decisive impact on the way the area develops and on where firms choose to locate. They go on to stress that these two scenarios are not mutually exclusive but rather correspond to different strategic approaches open to different sectors and specializations. They also discuss the impact of these strategies on where firms choose to locate within the Île-de-France and how these choices can contribute to spatial polarization.
