Organizational learning and purchase-supply relations in Japan: Hitachi, Matsushita, and Toyota compared

This article deals with the role of purchase-supply relations in organizational learning and knowledge-creation in Japan and how such relations are currently undergoing change. Drawing on interviews with managers, it presents case studies of the customer-supplier partnerships of three prominent Japanese manufacturing firms: Hitachi, Matsushita, and Toyota. The Hitachi case illustrates in a somewhat novel way the prevailing paradigm of how long-term, high-trust supply relations in Japan enhance organizational knowledge creation, learning, and innovation. The Toyota and Matsushita cases demonstrate that the dynamics of learning are behind two very different kinds of change in keiretsu supply networks. Toyota's evolving relationship with long-term partner, Dense Corporation, appears to fit the popular view that globalization and technological change are eroding Japanese keiretsu ties. The Matsushita case, by contrast, demonstrates that these same forces of change in other industrial settings may in fact be strengthening keiretsu-style partnerships.
