Comparison between industries about the functional and structural characteristics of keiretsu networks from the viewpoint of interorganizational learning

从组织间学习的角度比较了日本建筑公司与日本汽车、电器制造商的经销网络。在定量分析中，对一家大型建筑公司及其供应商组成的网络进行了社会网络分析，并与汽车制造商和电器制造商的网络在网络密度、联系强度和约束条件等方面进行了比较。在定性分析中，我比较了建筑公司和汽车制造商在任务改革、新业务启动和组织变革等非常规工作中的组织行为的稳定性。证实了建筑企业劳动生产率低下的原因是组织间网络的内容质量，而不是网络的数量和结构；在不稳定的环境中，任务绩效取决于变革推动者等优势人才，而不是建筑企业的系统性组织行为。

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.
