Study On The Influence Factors Of The Real Estate Price And Quantitative Analysis Model

In recent years,with the rapid development of national economy,the price of our national real estate is also continuing increasing quickly,vastly influencing the living quality of citizens and becoming an unstable factor of national economy's development.Therefore,real estate price has been an important economic and social issue which has been widely focused on.How to scientifically analyze the tendency of future price becomes the key for government to propose an efficient control policy.The development of the real estate industry is closely related to economic development.At present,the real estate market o f some developed countries has been increasingly mature.The tendency analysis of real estate price is gradually scientific.The development of real estate market is sustained and healthy under the guidance of the policy theory.In contrast,China's real estate market started late,a lot of theoretical research and policy development are still insufficient because of these prices are based on the future trend of the further study.Therefore,how to scientifically and effectively analyze the characteristics and tendency of the future price is of a broad theoretical and practical significance.The paper claims the research status of estate price tendency.Q ualitative analyzes the affecting factors of house prices,It analyzes and summarizes the main problems o f present methods,and proposes a model for tendency analysis which names diversified linear regression model which is based on information gain algorithm.Given one method of House prices trend analysis-quantitative analysis of multivariate linear regress ion model.The analysis of regression determines the accuracy and examination.What's more,this paper constructs a fitted curve of former indexes which can quantitatively analyze the tendency of future estate price.On basis of this,the paper has a furthe r study on error analysis,policy orient,application methods and so on.Finally,the paper optimizes the model and put up the advices on restraining estate price policy.1.Due to the imperfect and immature research which is more focused on extraction and analysis of influencing factors and ignores summarization of general model,the paper firstly analyzes the definition,characteristic and forming mechanism of estate price.It gives the common tendency model based on analysis of regression and determines the relationship of estate price influencing factors.And based on this,the paper classifies the prediction of estate price.2.The analysis of estate price influence is abundant,but it is lack of the research on key factors.Therefore,the paper analyzes the entropy and information gain between each factor which sets up the foundation on the tendency model.3.Aiming at the lack of general tendency mode,the paper analyzes the relationship between each important factors and estate price.Then we construct diversified linear regression model and obtain the unknown parameters by east square method.According to the general model,we analyze the tendency of the first-tier cities and second-tier cities and prove it.4.Because of the problem that the model ignores many influencing factors,the paper gives the modified method and proposes the advices on restraining estate price policy,providing a guidance of stable development of estate market.At the ending of the paper,we give a conclusion of research and look forward to the future of later research and policy direction.
