Research On Mass Appraisal Of Housing Property Tax Base On Parametic Regression Method

For the past years,with the continuous development of economy,property tax reform has become an imperative trend in the future of China’s real estate development.The fairness and accuracy for the assessment of tax base has become a key point in the collection of property tax,so it is very important to select appropriate evaluation methods.Except for the three traditional assessment methods,mass appraisal technique receives recognition in the assessment of real estate tax base among large number of scholars in foreign countries,which has become the first choice of property tax base assessment.However,due to the relatively late development of China’s real estate industry and the immature market,many people don’t have enough knowledge of the foreign advanced mass appraisal technique.Therefore,mass appraisal technique of property tax has provoked lots of researchers’ interest.On the basis of domestic and foreign scholars’ study,taking the application of parameters regression method in mass appraisal as a focal point,this paper will analyze mass appraisal technique and probe into the feasibility and advantage to combine parameters regression method in our country’s property tax base mass appraisal.Firstly this paper introduces parameters regression analysis method in detail,compares partition regression method and individual regression method and present the advantages and disadvantages respectively.This paper focuses on partition regression method,since tax base can be assessed more precise under partition regression method if the tax district division is accurately.Finally the paper use the real estate market of Nanchang city as research object,taking partition regression method as the premise,illustrated by the example of empirical research on mass appraisal of property tax base of Xihu District,Nanchang city.In empirical research,this paper firstly states the premise and conditions of partitioned evaluation in Xihu District to demonstrate the feasibility of partitioned evaluation.Then paper searches data information of real estate transaction in some similar places zones in Xihu District,Nanchang City,gather 75 sets of real estate transaction.At last,combined mass appraisal with parameters regression method to establish the corresponding mass appraisal model,the paper applied simulation partition evaluation to the real estate market of Nanchang City.And the empirical results show that the hypotheses have passed the test.Thus,for the country like China whose second and third tier cities are in the majority,and assessment techniques and methods remains relatively undeveloped compared with developed country,the parameters regression method can not only make people know about mass appraisal in overseas,can also provide reference on mass appraisal of the tax base in real estate tax collection for the second and third tier cities whish are similar to Nanchang at present.The research of this paper has carried out some simple innovations,based on the predecessors’ foundation.In this paper,based on the parameters regression analysis,we select the partition regression,and apply simulation modeling to mass appraisal of real estate tax base of Xihu District,Nanchang,which provide reference on mass appraisal of the real estate tax base for the relatively undeveloped second and third tier cities.If in the case of meet the prerequisites,using partition regression to do mass appraisal can not only guarantee efficiency but also take the accuracy into account,which has a strong application significance.However,individual resources are limited,there are some limitations of the study which still need further research.
