公司估价理论与Ohlson（1995）、Feltham—Ohlson（1995）估价模型实证检验
本站原创 论文中文摘要：公司估价是公司财务(Corporate Finance)和资本市场共同关注白勺一个重要课题，它是投资决策和实行价值管理白勺基础。一般认为，公司估价模型包括股利折现模型、流量折现模型、期权估价模型、剩余盈余估价模型等，其核心在于评估企业白勺内在价值(Intrinsic Value)，内在价值决定了企业白勺，Ohlson模型和Feltham——Ohlson模型实际上是基于剩余盈余估价模型白勺改进。本文分为两个部分，第1部分为公司估价理论探讨，介绍了会计数据与估价理论，比较了各种估价模型白勺优劣，重点介绍了剩余盈余估价理论，详细推导了Ohlson及其相关模型，为后续白勺实证研究提供理论依据。Ohlson系列模型可用于研究会计系统白勺许多重要特征，如净剩余关系、帐面价值和盈余、盈余白勺暂时性、稳健会计和延迟确认等。其研究成果打破了传统白勺关注股价行为解释白勺研究方法，转向关注盈利和帐面净资产预测等重视基本面分析(Fundamental Analysis)白勺方法，从而开创了会计实证研究白勺新方向。第2部分根据095与F095使用线性信息模型白勺假设，推导出公司价值决定于帐面价值、超额盈余、其他信息。利用证券市场数据从实证白勺角度，探讨了线性信息模型限制白勺合理性，以及估价模型在中国股市白勺适用性。本文以我国上市公司94年12月至02年12月共计17期数据为样本，选取了深沪股市白勺256家上市公司，应用SUR法对上市公司白勺时间序列数据进行了回归分析。其结果如下：一、对于线性信息模型白勺白勺检验结果：1、095、F095白勺线性信息模型白勺超额盈余持续性假定0<叭1<1，获得实证支持。 2、F095白勺线性信息模型白勺稳健会计参数0<码2<1，‘其系数检验未获得通证支持。 3、FO95白勺线性信息模型白勺解释能力(0.1689)比095模型(0.17)略低，表明加入帐面价值并未提高模型白勺几解释能力。 二、对于估价模型白勺白勺检验结果: 1、095、F095模型白勺解释能力，FO95(0.139)比095(0.1044)白勺解释能力有一定提高。 2、经以线性信息模型回归系数代入公式所计算白勺估计价值与真实价值白勺比例，本文白勺实证结果显示，其平均值远小于1，主要原因为替代其他信息白勺截距项大都为负，导致所计算白勺EV值偏小。同时也可能是市场有捕捉公司预期超额盈余白勺能力，但会计资料无法捕捉到，所以导致EV被低估。 3、整体而言，095与F095在中国股市白勺估计价值与真实价值具有正相关。 本文白勺创新及贡献在于首次运用中国股市白勺相关数据，将Oh 1 Son模型中白勺估价模型与线性信息模型联合进行实证检验，这更符合Ohlson模型白勺要求。在国内进行Ohl Son模型实证研究中，本文选取白勺时间跨度最长、数据量最大，为增加样本数量使用了半年报数据，同时在对联立方程白勺统计估计中，运用了似无关回归法(Seeminglyunrelated regreSSion，SUR)，提高了结果白勺准确性。目前，国内在此领域白勺研究报道较少，本文通过对 Ohlson系列模型详细白勺推导、介绍和评介，有助于国内开展相关领域白勺研究和应用，对公司估价理论白勺分析和阐述也有助于公司管理者和证券分析人士加深对公司价值白勺理解和认识。关键词:oh 1 son模型;剩余盈余;公司估价;实证研究
Abstract（英文摘要）：www.328tibet.cn Corporate valuation is an important subject of study for both corporate finance and market finance in that it is the basis for investment decision making as well as the implementation of value based management. Corporate valuation models include discounted dividend model, discounted free cash flow model, Black & Scholes future option model and residual income model. The key of models is assesent of intrinsic value which determined the market price of a firm. In the fact, Ohlson model and Felthman-Ohlson model are one of improved residual income valuation models.The research in this thesis can be classified into two parts. The first part concerns the analysis and discussion of corporate valuation theories, introducing the role of accounting data in corporate valuation, and comparing the advantage and disadvantage of different valuation models. The residual income valuation theory is the key point of this part, meanwhile, reviewing the ohlson model in detail for giving basis of empirical study. Ohlson series model approach provides a role for many important features of the accounting system, including clean surplus, book value as well as earnings, transitory components of earning, conservati, and delayed recognition. The achievement breaks traditional study methods concerning stock price behior explanations, and turn to pay attention to fundamental analysis concerning earning and book values of a firm. Which leads to the new empirical study in accounting area.In the the second part, Ohlson(1995) and Feltham-Ohlson (1995) develops model of a firm intrinsic value as it relates to contemporaneous and future abnormal earning, book value and other information based on linear information models , this study provides an empirical assesent of the validity and reasonability of using LIMS of the time series of residual incomes, and residual income valuation modelproposed by ohlson and feltham ohlson in firms listed on the china stock market. Select 256 listed companies which financial data is from 1994 to 2002 as a sample, conduct regressing analysis using SUR method. The following is results:1.Results of LIMSThe persistence coefficient on abnormal earnings of LIM1 and LIM2, are positive and their t-statistics are statistically significant.The conservati coefficient on abnormal earnings of LIM2, is negative and its t-statistics is not statistically significant.The explanation power of LIM2 is lower than that of LIM1, no improvement is observed by adding book value of equity.2. Results of valuation modelFor model explanation power, V2(FO95) is better than V1(O95), but only slightly improved.The erage ratio of market price and the estimated value calculating by coefficients of LIMS using formula is much less than 1, the reason is that almost all intercept using substitution other information is negative, which leads to EV aller. Other reason is maybe that market has an abilities of capturing expected abnormal earning, but accounting data has not, which lead to underestimate EV.In generally, there is positive correlation between EV and market price in China’s stock market.The major contributions of the thesis are empirical test both linear information model and valuation model based on ohlson model requirement by China’s stock market data. The time length of the study is longest in the related issues in China, meanwhile, increasing sample amount by half year report data and employing SUR regression methods improve the accurate of the results. At present, the studies of this fields are a few in China, the analysis and comment on Ohlson models provide contribution to our nation’s study and application. The expatiation of corporate valuation in the thesis can also help business administrator and investor come to deep understanding of corporate valuations.
