I compared keiretsu network of Japanese Construction Company with them of Japanese Automotive Manufacturer and Electric Apparatus Manufacturer from the viewpoint of interorganizational learning.In quantitive analysis, I carried out a social network analysis of the network which consisted of a major construction company and its suppliers, and compared the network with them of automotive manufacturers and electric apparatus manufacturers about density of the networks, strength of the ties and constraint of each company.In qualitive analysis, I compared the construction company with the automotive manufacturers about the stability of their organizational behaviors in the nonroutine works, such as task reforms, new business starts and organizational changesAs a result, they were confirmed that the cause of inferior labor productivity of the construction company was quality of contents of its interorganizational network rather than quantity and structure of its network, and that task performances in the unstable environment depended on some superior persons, such as change agents, rather than systematic organizational behaviors in the construction company.
