| 摘 要： | 介绍了一种用系统核与核度理论和灰色关联分析来选取房地产预警指标的新方法,并以武汉市为例证明了这种方法的有效性.这种方法可以确定出能够反映房地产状况的少数几个指标,进而可以通过这少数指标对房地产发展趋势进行预警:根据原始指标数据列间的灰关联程度,建立房地产预警系统的拓扑图,利用图论的知识来求取拓扑图的核,选取房地产预警指标.

| Abstract: | In this paper,we give a new method of selecting real estate early warning indexes system based on based on the theory of system core and coritivity and gray correlative analysis: According to the dependent degree of indexes,we can get the graph of real estate system and it′s core,when we study the real estate system,we only think of several core indexes.We also used real estte system of Wuhan as an example to testify the efficiency of the method. |
