Analysis Of Mass Appraisal System Based On The Property Taxation Imposition

Mass appraisal is one of the methodologies that have been employed for the real estate assessment. The march of computerized assessment has already been started and achieved great success in other developed countries. Even some under-developed, economically transition countries are taking steps to build their own computerized mass appraisal system. In China, although without substantial practice, some economists are discussing the implementation of mass appraisal in the property taxation. Research on the process of mass appraisal practice in property tax can provide evaluative support to the imposition of property tax. Therefore, the study of this paper is of certain value to the relative area.First of all, the paper gives a systematic summary of the concept, initiation, development, method and procedure of Mass Appraisal. Furthermore, substantial analysis is carried out on the possible data source and the legislation for data acquirement. Also, some useful advice is gave based on the economical situation in China, about the descriptive dataset of the property, union of the information from the property management department and the government tax bureau is a satisfied measure to obtain valuable data costless; dataset about the transaction is relatively hard to obtains, so the compulsory power implemented by the government is necessary to ensure the data completeness; sales record should be kept securely in order to do the compare work later on.About the literature review, since the western countries started real estate appraisal in a relatively early step, systematic analysis is implemented on the Computer- Assisted Mass Appraisal (CAMA)in developed countries such as South Africa and Lithuania, etc. From their experience, we know that launching the system from central to local area is effective and costless since the information in bigger, more developed cities is easier to achieve and beneficial to our initial practice. Further more, their routine procedure of the implementation is also adoptable to our own practice. The research also involved with some other countries which have employed Mass Appraisal in other areas. Some aspects can be employed in China, such as legislation, appraisal implement, developmental direction, etc.About the modeling in this paper, based on our counties'special economic situation, the sales compared approach is adopted and the multi-linear regression is used for model test and revision. The data adopted is collected from the real estate of Xiamen. The outcome of the analysis is satisfactory and implies that Mass Appraisal is adoptable in Chinese practice.At last, the paper discussed the criteria of the practical implementation and finds some answers for the questions of the imposition of property taxation in China.
