项目摘要

Equivalent nature evaluation of IFRS, Japan GAAP, and U.S. GAAP was tried based on the annual report of the U.S. GAAP reconciler. The precedence research on whether reconciliation to U.S. GAAP is useful for an investor was classified and reviewed in three types. Three correction models which contain frame of U.S. GAAP earnings adjustment differences variable; RCNC [(GAAP earnings adjustment differences/foreign GAAP earnings or IFRS earnings)] which divided the absolute value by the final stock price in the earnings capitalization model, book value model, and residual income valuation models which were used by precedence research were added.Vuong test compared the stock price explanation power of earnings capitalization model of 23 U.S. GAAP reporters (14 Japanese companies are included) and 63 U.S. GAAP reconcilers (5 IFRS application companies, 58 its native country GAAP application companies), the book value model, and residual income model. Although the ranking and of dominance of book value model and earnings capitalization model differed from precedence research, the stock price explanation power of the residual income model was most excellent. The explanation power of the U.S. GAAP repoters endured it of the U.S. GAAP reconcilers. According to Vuong test, the contents of an increment information of the U.S. GAAP earnings adjustment difference variable were not checked, but the significant relation was found out between the U.S. GAAP earnings adjustment difference variable and the stock price(5% level). The result of research about these was announced in Accounting, Vol.172, No.2 (August, 2007).

根据美国GAAP对帐的年度报告，对IFRS，Japan GAAP和美国GAAP的同等性质评估进行了尝试。关于与美国GAAP的和解是否对投资者有用的首先研究被分为三种类型。包含美国GAAP收益调整差异框架变量的三个更正模型； RCNC [（GAAP收益调整差异/外国GAAP收益或IFRS收益）]，将绝对价值除以收益资本化模型，账面价值模型和剩余收入估值模型的最终股票价格，并添加了先例研究使用的剩余收入估值模型。 Vuong测试比较了23位美国GAAP记者（包括14家公司）和63位美国GAAP对帐的股票价格解释能力模型（包括14家日本公司）（58家IFRS应用公司，58家著名国家GAAP应用公司），账面价值模型和剩余收入模型。尽管账面价值模型和收入资本化模型的排名和优势与优先研究不同，但剩余收入模型的股票价格解释能力最为好。美国GAAP申请员的解释能力忍受了美国GAAP和解者的。根据Vuong测试，未检查美国GAAP收益调整差异变量的增量信息的内容，但是在美国GAAP收益调整差异变量与股票价格（5％）之间发现了显着关系。有关这些研究的结果在《会计》第172卷，第2期（2007年8月）中宣布。
