The ongoing liberalization of markets and the simultaneous emergence of newly
industrialized countries, particularly the quartet Brazil-Russia-India-China, have contributed
to an unparalleled global economy and trade growing steadily over the last 20 years. If the
current economic crisis has somewhat reduced the volume of these exchanges, concerns
about a global sourcing and/or subcontracting internationally will have taken more
importance in the quest for business competitiveness.
For multinational corporations, the globalization of trade implies a global flow
management. It is, therefore, left to the strategic choices of companies to ensure supply
or production at the lowest cost, to ensure value creation throughout the international
supply chains, and sometimes relocate activities to improve responsiveness to markets.
From the point of view of international management, and more specifically the
management of multinational firms, such trends raise questions about the different
theoretical approaches used in the study of control of global flows. Michael Porter’s
approach of explaining value creation as limited to individual enterprise has become
outdated by changes in value generating activities, notably due to outsourcing. The
concept of value chain, in line with the value system of Porter, is then extended to include
new activities, especially the phases upstream and downstream business. Similarly, the
concept of global value chain, similar to the concept of industry in Economics (Rastoin
et al., 2005), permits an overrun of the concept of global commodity chain (Gereffi and
Korzeniewicz, 1994) by initiating a reflection on a territorial fragmentation of production
processes across multiple areas/countries worldwide. This concept also is an attempt to
group approaches in industrial economics (Bencharif and Rastoin, 2007) in the framework
of the theory of Structure-Conduct-Performance (SCP). Finally, the concept of Supply
Chain Management (SCM), which is a management science, broadens the spectrum
approaching relationships in a systemic vision through the coordination of all
components and stakeholders’ international supply chains.
