Land Valuation Research Based On Residual Method

With the deepening of economic system reform,profound changes are taking place in China’s land market.we should do a good job in the land value relationship of the real estate market,which is closely related to the national economic life of the existing land.Scientific and reasonable land value evaluation can fully protect the core interests of the existing land owners,and ensure the efficient and intensive use of the land,so that it can play more value,and also let the new land ownership The winner doesn’t have to pay extra cost.Multi win is not only the core requirement of land transfer subject,but also the need to ensure the harmonious and stable development of the whole society,so as to avoid more social problems derived from land transfer.Residual method is a method used for land price evaluation.It is a method to determine the land price by verifying the development cost of the real estate,so as to determine the proportion of land price in the total value of the real estate.It is not only beneficial for real estate appraisal agencies and relevant government departments to determine the actual cost of developers consumed in the development of commercial housing,but also conducive to the formulation and evaluation of reasonable commercial housing prices.At the same time,it also plays a very important role in collecting the amount of land transfer fees for the public housing purchased according to the preferential policies.Based on the introduction of the land value estimation method,this paper uses the principal component analysis method and the regression method to add the regression of the discounted part of cash flow to the residual method of land value estimation.In this paper,the principal component regression model is established and used to predict the prices of different buildings for rent and sale.Combined with theory and practice,this paper selects real estate projects to verify and analyze.In case analysis,it forecasts the land value through empirical analysis.Through comparative analysis,it compares the discounted residual cash flow method improved by the principal component regression method.The conclusion of this paper is that the residual method modified by principal component regression is better than the market method.The main conclusions are as follows: 1.There are some deficiencies in the existing land value calculation methods,and there is room for improvement;2.Using the principal component regression method,on the basis of thesurplus method,adding the cash flow method can improve the precision of the surplus method;3.The four factors of Xi’an labor quantity,Xi’an GDP,loan interest rate,and per capita income of households will affect the land for rental purposes Value has an impact;4.Xi’an GDP,per capita income of households,new affordable housing area,per capita residential building area,real estate development investment,Xi’an commercial housing sales price will have an impact on the land value for the purpose of sale;5.The residual method modified after the use of principal component regression is significantly better than the market method for the estimation of land value.
