“…As with New Zealand-based research, case studies of inter-firm linkages provide useful perspectives on the extent of involvement of foreign firms in local industry, but are typically limited to particular industries [Turok, 1993;Brown, 1998;O'Malley and O'Gorman, 2001], local sourcing [Ruane and Holger, 1997;Williams, 1999] or single firms [Barrow and Hall, 1995]. Some studies have taken a more comprehensive approach in their examination of inter-firm interactions [Rodriguez-Clare, 1996;Dunning, 1998;UNCTAD, 2001], particularly with respect to affiliate -supplier/subcontractor linkages [Poon, 1996;Raines et al, 2001] and type of FDI [Williams, 1997].…”
