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

本文从组织间学习的角度对日本建筑公司的经连会网络与日本汽车制造商和电器制造商的经连会网络进行了比较，在定量分析中，对一家大型建筑公司及其供应商组成的经连会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经连会网络在网络密度上进行了比较，在定性分析中，本文比较了建筑企业和汽车制造企业在非常规工作中，如任务改革、新业务启动和组织变革等，组织行为的稳定性。他们证实，建筑公司劳动生产率低下的原因是其组织间网络内容的质量，而不是数量，其网络结构，以及在不稳定环境中任务绩效取决于一些上级人员，如变革者，而不是建筑公司系统的组织行为。

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.
