【摘要】：在灰色聚類評(píng)估分析中,當(dāng)灰色聚類系數(shù)無顯著性差異時(shí),按照已有的灰色聚類方法無法對(duì)聚類對(duì)象進(jìn)行準(zhǔn)確的聚類,而在實(shí)際研究中經(jīng)常會(huì)遇到聚類系數(shù)無顯著性差異這類問題。因此本文提出了一種新的灰色綜合聚類方法。具體步驟是:首先計(jì)算各聚類對(duì)象的聚類系數(shù),并對(duì)其進(jìn)行歸一化處理;再根據(jù)對(duì)象中每一灰類的灰色聚類系數(shù)在聚類過程中的作用,計(jì)算聚類對(duì)象的綜合聚類系數(shù);最后根據(jù)綜合聚類系數(shù)對(duì)聚類對(duì)象進(jìn)行聚類,確定聚類對(duì)象應(yīng)屬的灰類。并且證明了當(dāng)聚類對(duì)象的聚類系數(shù)差異大于1-2/S時(shí),一般灰色聚類方法與灰色綜合聚類方法所得聚類結(jié)果完全相同。最后,以江蘇省第二產(chǎn)業(yè)內(nèi)部主導(dǎo)產(chǎn)業(yè)選擇為例進(jìn)行了實(shí)證分析。
[Abstract]:In the grey clustering evaluation analysis, when there is no significant difference in grey clustering coefficient, the existing grey clustering methods can not cluster the clustering objects accurately. However, there is no significant difference in clustering coefficient in practical research. Therefore, a new grey comprehensive clustering method is proposed in this paper. The concrete steps are as follows: firstly, the clustering coefficients of each clustering object are calculated and normalized, and then the comprehensive clustering coefficients of each grey class are calculated according to the function of the grey clustering coefficients in the clustering process. Finally, the clustering object is clustered according to the comprehensive clustering coefficient, and the grey class of the clustering object is determined. It is also proved that when the difference of clustering coefficients of clustering objects is greater than 1-2 / S, the clustering results obtained by the general grey clustering method and the grey comprehensive clustering method are exactly the same. Finally, taking the choice of the leading industry in the second industry of Jiangsu Province as an example, the paper makes an empirical analysis.
