【摘要】：在以往关于房地产市场运行特征的研究中，鲜有文章能够从房地产市场运行的资金面积进行分析，并且大都是从需求与供给等因素观察房地产市场运行特征的趋势。本文选取了从2005年到2011年国内24个城市房地产市场运行相关的31个变量，将从资金面积匹配分析房地产市场运行特征的情况。本文从选取的房地产运行特征的变量群，通过数据挖掘的方法找出合适的子集变量群，而探索出的子集变量群正好是近似于正交的两个变量群，称它为拟正交变量群。接着进行特征提取出符合要求的面积因子和资金因子，同时通过特征构造得到因子综合得分。同时基于资金面积因子方法得到一个分类结果，与基于数据挖掘中的聚类算法的另一个分类结果，进行比对，选择更好的基于资金面积因子方法的分类结果。并可使用由特征构造出的综合因子指标分析城市的房地产市场运行水平。最后，建立资金面积匹配与泡沫的关联模型，该模型运用于房地产市场运行特征的合理性分析。经过分析后得到定性的结论:资金面积规模匹配，则房地产市场运行合理；资金面积不匹配时，，如果资金规模高于面积规模，则房地产市场运行不合理；资金面积不匹配时，如果资金规模低于面积规模，则房地产市场运行合理。
[Abstract]:In the past about the real estate market movement characteristic research, few articles can carry on the analysis from the real estate market movement capital area. And most of the real estate market from demand and supply and other factors to observe the trend of the operation of the real estate market. This paper selects the 24 cities from 2005 to 2011 in the operation of the real estate market related to 31 variables. Will match from the capital area analysis of the real estate market operating characteristics of the situation. In this paper, from the selected real estate operating characteristics of the variable group, through the method of data mining to find the appropriate subset of variables, and the exploration of the subset of variables is similar to orthogonal groups of two variables. It is called the quasi orthogonal variable group, and then the area factor and the fund factor which meet the requirements are extracted by the feature, and the comprehensive score of the factor is obtained by the feature construction. At the same time, we get a classification result based on the fund area factor method, and compare it with another classification result of the clustering algorithm based on data mining. A better classification result based on the capital area factor method is selected, and the comprehensive factor index constructed from the features can be used to analyze the operation level of the real estate market in the city. Finally, the paper establishes the correlation model between the capital area matching and the bubble, which is applied to the rationality analysis of the real estate market operation characteristics. After the analysis, the qualitative conclusion is obtained: the capital area scale matching. The operation of real estate market is reasonable; When the capital area does not match, if the capital scale is higher than the area scale, the real estate market operation is unreasonable; When the capital area does not match, if the capital scale is lower than the area scale, the real estate market operation is reasonable.
