“…More than contradictory perspectives, these approaches are seen as complementary in the study of the process of innovation. The Industrial Cluster approach stresses the competitive pressure of the environment on the firm (Porter, 1990(Porter, , 1998Stern et al, 2000;Porter and Stern, 2001;Furman et al, 2002), while the role of cooperation amongst firms is highlighted in the Industrial Districts' approach (Becattini, 1990;Sengenberger et al, 1990;Brusco, 1992;Schmitz, 1992). The Industrial Networks approach enhances the role of the agents, activities and resources (Hakansson 1987;Hakansson andJohanson, 1988, 1992;Johanson and Mattson, 1991); whereas the Resource-Based View points out, mainly, the resources and the internal capacities essential to the process of innovation (Pfeffer and Salancik, 1978;Wernerfelt, 1984Wernerfelt, , 1995Prahalad and Hamel, 1990;Levinthal, 1989, 1990).…”
