摘要
本文建立了一种基于指标重要性权重的区域经济结构的聚类分析模型 ,并用于城市经济结构分析。模型依据是 :1 .不同影响指标在区域经济结构中起的重要性作用是不相同的 ,反映这种不同是必要的 ;2 .区域经济结构指标可化为效益型指标 ,同一样本的规范化指标观测值乘以相应的指标权重后 ,对不同指标具有可加性。与主因素分析等模型比较 ,本模型具有结构简单、计算量小。
The paper sets up a value cluster model of district economic structure based on weight of index and puts it into analysis of city economic structure. Foundation of model: 1.Different index's importance in the economic structure is different, which is different in reflection of difference; 2. Index of district economic structure can be changed into profit's index, after observation value of standardization index in a sample multiply its' relevant index's weight, different index can be added. Compared with model of main factor's analysis, the model has advantages, such as simple structure, small quantity of calculation and obviously interpretable value cluster.
