Comparative Study of Hiving Off Strategy and the Delegation of Authority

1. 制定授权的承诺模式：将业务部门从公司主体中分离出来，称为“分拆”，是一项重要的组织战略。为什么公司会采取这样的策略呢？为什么不能在现有的组织中实现与分离情况相同的好处，例如通过增加一个新的业务部门？我们认为这是公司承诺将权力下放给其子公司或附属公司的一种手段。因此，我们建立了一个运用不完全契约理论的委托承诺模型。不完全契约理论的实证分析：利用probit统计模型和问卷数据对承诺模型进行实证分析。当时我们采用了将其与替代代理模型进行比较的方法。因此，承诺模型得到了大部分的支持。在日外国公司访谈：它为我们提供了一个标准模型，在这个模型上，我们可以比较日本公司和美国公司部门授权的特点。日本企业的采访：我们采访了四家日本企业，主题是企业内部和外部部门的委派。这说明了日本公司与美国公司的比较特点和局限性。未来的研究计划：我们将有(1)修正承诺模型的估计，以解决解释变量的问题；(2)从比较研究的角度进一步开展包括剥离在内的企业集团管理战略研究；(3)对几家美国公司的整体子公司和关联公司进行新的问卷研究。

1. Making a Commitment Model of Delegation : Separating of an operating division from the main corporate body, called "hiving off", is an important organizational strategy. Why do companies take such a strategy? Why can not the same benefits as the case of hiving off be achieved within the existing organization, such as by adding a new business division? We regard it as a device for a corporation to commit herself to the delegation of authority to its subsidiaries or affiliates. We therefore made a commitment model of delegation to which the theory of incomplete contract was applied.2. Empirical Analysis of the Theory of Incomplete Contract : We conducted empirical analysis of the commitment model using probit statistical model with questionnaire data. At that time we adopted the method of comparing it to an alternative agency model. As a result of it, the commitment model was mostly supported.3. Interview of Foreign Corporations in Japan : It gave us the standard model on which we compare characteristics of the delegation of authority to divisions in Japanese firms with ones in Americans.4. Interview of Japanese Corporations : We interviewed four Japanese corporations on the topic of delegation to in-house and out-house divisions of business unit. This illuminates the comparative characteristics and limits in Japanese firms with ones in Americans.5. Plan of Future Research : We will have (1) to revise estimations of commitment model to resolve the problems in explanatory variables, (2) to develop more the study of management strategy of business group, which includes hiving off, from a viewpoint of comparative study, and (3) to do a new questionnaire research on the whole subsidiaries and affiliates of a few American corporations.
