【正文】 結(jié)果解釋 Equamax:全體旋轉(zhuǎn),對變量和因子均作旋轉(zhuǎn); Maximum likelihood:極大似然估計法; 因子提取方法選擇對話框 描述性指標選擇對話框 因子分析對話框點擊Descriptives...鈕,彈出Factor Analysis:Descriptives對話框(),在Statistics中選Univariate descriptives項要求輸出各變量的均數(shù)與標準差,在Correlation Matrix欄內(nèi)選Coefficients項要求計算相關(guān)系數(shù)矩陣,并選KMO and Bartlett’s test of sphericity項,要求對相關(guān)系數(shù)矩陣進行統(tǒng)計學(xué)檢驗。鈕使之進入Variables框。 數(shù)據(jù)準備X1X2X3X4X5X6X7 激活數(shù)據(jù)管理窗口,定義變量名:分別為XXXXXXX7,按順序輸入相應(yīng)數(shù)值,建立數(shù)據(jù)庫。 統(tǒng)計分析在對話框左側(cè)的變量列表中選變量X1至X7,點擊216。 點擊Extraction...鈕,彈出Factor Analysis:Extraction對話框(),系統(tǒng)提供如下因子提取方法: Principal ponents:主成分分析法; Principal axis factoring:主軸因子法; 因子旋轉(zhuǎn)方法選擇對話框 Quartimax:四分旋轉(zhuǎn),對變量作旋轉(zhuǎn);本例選正交旋轉(zhuǎn)法,之后點擊Continue鈕返回Factor Analysis對話框。 點擊Scores...鈕,彈出彈出Factor Analysis:Scores對話框(),系統(tǒng)提供3種估計因子得分系數(shù)的方法,本例選Regression(回歸因子得分),之后點擊Continue鈕返回Factor Analysis對話框,再點擊OK鈕即完成分析。 KaiserMeyerOlkin Measure of Sampling Adequacy是用于比較觀測相關(guān)系數(shù)值與偏相關(guān)系數(shù)值的一個指標,其值愈逼近1,表明對這些變量進行因子分析的效果愈好。 Listwise deletion of cases with missing valuesMean X4 X3 .36379 .28347 .16328 X7 .35732可見其與第一因子更近,與第二因子更遠。Extraction 1, Principal Components Analysis (PC)PC .74646 .79644 .70890 .97172X7 *旋轉(zhuǎn)的目的是使復(fù)雜的矩陣變得簡潔,即第一因子替代了XXXX7的作用,第二因子替代了XXX6的作用。 1 Kaiser Normalization.VARIMAX converged in 3 iterations.Rotated Factor Matrix:Factor .54656Factor Transformation Matrix:Factor Factor .38873這些值既可用于模型診斷,又可用于進一步分析。 關(guān)鍵詞:服務(wù)業(yè);競爭力;因子分析 中圖分類號:N949 Abstract During the last ten years, speeding up the development of service industry and enhancing its position in national economy is one of the most important directions of the economic policy of our government. Along with the progress of Development of the West Regions, all circles concerned starts paying attention to the development of service industry over there. Based on the theories of service industry and its petitiveness, this research makes use of factor analysis to evaluate the petitiveness of service industry in twelve western provinces and regions, and then brings forward countermeasures an
