BP Network-based Research On Coordination Degree Of Real Estate And Urban Economic Growth

In recent two years, China begins to regulate the real estate, which indicates the"bubble" in real estate will be suppressed, the real estate market will gradually return torational market economy framework. The development of Chinese real estate will finishthe original extensive mode. The future of the real estate industry will more stable, paymore attention to the coordination with the development of the city’s overall economic.So the research in the coordination of the real estate and the city’s economicdevelopment will be conducive to guide the future development of Chinese real estateindustry.In order to evaluate the relationship between the real estate and the city’s economicdevelopment effectively, this paper adopts the concept of coordination degree. From theperspective of coordination degree, the paper lists five external performance of thecoordination of the real estate and the city’s economic development. And through theanalysis of some cases, the paper qualitatively analyzes the coordination degree ofHarbin in five aspects. Then by combining these cases, the paper further analyze thetheoretical interaction between the real estate and the city’s economic development, andbase on their interaction, the paper lists the second level indicators, thus the evaluationsystem has been set up. Analytic Hierarchy has been used to build the weight of theseindicators and the comprehensive evaluation formula, which will be used in themodeling of the evaluation system. The BP neural network algorithm and MATLAB hasbeen used to build the evaluation system. Finally, take Harbin as an example, we trainthe model in MATLAB for two times, and then compare the result, and through theproblem reflected from the model, the paper provides some reasonable policyrecommendations.Through the results of analysis, it shows that the evaluation system of coordinationdegree and evaluation model in the paper is proper. Through the evaluation ofcoordination between the real estate and the city’s economic development, we canpropose some effective policy recommendations and guidance for government andcorporate.
