Business valuation based on modern economy is one of the most difficult and comprehensive professional work in asset appraisal, but also stands for the trend of the appraisal. as china implemented planned economy all the long in the past years, the concept of business value was proposed later than other advanced countries. the study on the theory and method of business valuation we made is relatively backward. all these lead to that we merely use cost method in practice. with the improvement of market economy, the validity of cost method is challenged. hunting for appraisal methods suitable for china circumstance has become more and more urgent. this thesis presents its own opinion on the adjustment of the basic frame of theory of business valuation. for the first time, it puts systems theory into the study of the theory base, and believes that the enterprise as a compound entity has higher efficiency than the sum of its constituent, and then proposes new appraisal assumption. aiming at the obscure understan ding, it analyses a group of conception related to business valuation. after giving a whole analysis and study, this thesis indicates the income approach which emphasizes earning - capacity of a enterprise should become the correct choice of china, and makes a further study on the origin - features and feasibility of this method
植根于現代經濟的企業價值評估是資產評估中綜合性最強，技術難度最高的業務之一，也是評估業未來的發展方向，由於我國過去長期實行計劃經濟體制，企業價值概念的提出和運用時間較晚，缺少現代經營理念的積累，企業價值評估的理論與方法的研究比較滯后。本文試圖以理性分析和案例分析相結合的方法，系統研究和分析企業價值評估的基礎理論及其現實條件下，適應我國經濟發展的評估方法，以期為構建有中國特色的企業價值評估理論和方法體系做一些有益的探索。文章以企業價值評估的基本概念為起點，在對眾多關于企業性質的學說和理論觀點進行概括抽象的基礎上，指出了整體性、持續經營和盈利性是企業的重要特徵，依據企業的整體性運用系統方法闡明了企業的價值大於組成企業的單項資產價值之和，據此提出了反映企業價值評估特點的有機組合增殖假設；依據盈利性的特點，強調了企業價值評估的核心應為企業的獲利能力，而不是組建企業的成本；對企業價值、企業價值評估含義、特點的論述以及對相關概念的辨析表明了作者的個人觀點和文章的基本定位，而從評估目的入手劃分的以產權變動為目的的企業價值評估和以財務決策為目的的企業價值評估與企業價值評估的假設、評估核心共同決定了評估方法的選用。 -
