The Improvement Of Market Comparison Approach And Case Studies In Timber Assets

The purpose of this study is to improve the objectivity of the assessment of timber assets by systemic studies on market comparison approach of timber assets, choose the common method - market comparison approach as study object. The study introduces grey theory, fuzzy cluster analysis method and AHP to make a comprehensive analysis to determine the weight of factors, the choice of reference case, the correction factor. Through the study on improved market comparison approach of timber assets, it's not only conductive for the national macro to control the price of forest resources, but also for decision-making of forest management, the main conclusions are as following:1. This study makes a comprehensive and systematic study on theory and practice of the market comparison approach in the application, introduces the grey theory, fuzzy cluster analysis method, AHP, analysis the theoretical basis, application conditions, methods steps of market comparison approach in timber assets , systematically discussed the choice of influencing factors of asset prices and the amendment of quantitative detail, makes more profound analysis on the choice of comparable case and propose viable solutions.2. Using grey theory analysis the associated degree of influencing factors of price. The price of timber asset are influenced by various factors, the impact of each factor are different. Grey theory is low request on samples number and regulation, small amount of calculation, and its results are accurate, it has high value and broad application prospects in timber asset.3. Introducing fuzzy cluster analysis method to choose comparable case. Currently, the choices of comparable case are decided on the experience of assessors, which has a certain degree of subjectivity. Fuzzy math could descript the similarity between reference case and objects quantitatively, this study choose a suitable confidence level, cluster reference case and objects, judged the magnitude of similarity degree of reference case and objects through the magnitude of fuzzy similarity. It could solve the problem of how to choose the most similar object when using the market comparison method to assessment the timber asset.4. Determining the weight of comparable cases though AHP.AHP is a multi-objective decision-making method that combined qualitative and quantitative. Using it to determine the weight of reference case and objects, simplify and reasonable, it is applicable to the quantitative indicators and qualitative indicators. It is superior for some situation in forestry survey that some data can not be collected, long cycle or losing data easily.
