At the turn of the century, questions about multinational firms' strategies as regards the forces, on the one hand, of globalization and, on the other hand, of the regional and local dimensions are very much to the fore. What are the new constraints and the new theories to explain global-local multinationals' strategies at the beginning of this new era? Understanding multinationals' strategies is an essential task, but the range of strategies is not simple or homogenous; they are increasingly complex, the outcomes of different logics and different choices. Since the 1980s, new economic areas have been created - the EU, MERCOSUR, ASEAN, NAFTA - there has also been the integration of Eastern European countries following the lifting of the iron curtain. A real movement of regional integration has been witnessed in these areas, which has modified firms' strategies. But simultaneously there has been another factor: the global or regional dimension is one determinant, but there is also the local dimension, for example in production siting. This volume presents the work of internationally renowned specialists on multinational strategy, addressing the main questions about globalization, firms' and countries' competitiveness, the impact of regionalism, agglomeration and industrial clustering, oligopolistic interactions, mode of entry, strategic location choice and relocation and public aid. This book is the first volume presenting the outstanding work from the Seventh Sorbonne International Conference on Multinational Firms' Strategies.
