メインバンク-企業関係と会計政策

本研究的主要目的是提供主银行制度下的战略性会计政策选择。日本的大多数大公司都与中央银行有密切的联系。主银行通常是企业贷款份额最大的银行，并为企业提供各种服务。在这种制度下，日本企业在会计政策方面将选择什么样的投资组合？为了检验上述问题，我们提出了八个假设。这些假设是在主银行对企业的承诺水平上设计的。不幸的是，这项研究的结果与八个假设不一致。然而，我发现主银行承诺的公司选择自由的会计政策组合。所以我把这种政策选择称为承诺效应。鉴于承诺效应的存在，我认为主银行的控制制度有两个含义。一是该制度赋予了现有管理团队以长远眼光为基础的管理自由裁量权。当管理者打算动态改变管理风格时，这种支持是重要和有用的。另一个优点是，这种制度不需要严格的管理，而不需要对财务结构进行快速重组。无论如何，深入分析承诺效应是一个重要的课题。

The main purpose of this researchprovides the strategic accounting policy choice under the Main Bank system. Most of Japanese large firms have closely connection with Main Bank. Main Bank is generally the largest loan share among lenders to the firm and provider to various services to the firm. Under the system, what kind of portfolio will Japanese firms select about accounting policy? To test above questions, eight hypotheses are specified. These hypotheses are designed on the level of commitment of Main Bank to firm.Unfortunately, the results of this research are not consistent with eight hypotheses. However, I found that firms committed by Main Bank are selecting the liberal portfolio of accountiong policy. So I called this policy choice the Commitment effect. Given that the existence of the commitment effect, I think that the control system by Main Bank has two implications. One is that this system gives the discretion of management based long-term perspective to the existing management teams. Such a supports are important and useful when managers intend dynamic changes in management style. The other is that this system doesn't require tough management to the effect that the needs of rapidly restrucharing about financial structure. Anyway, deep analyzes about commitment effect are a significant subject.
