1、现代地理学中的数学方法本次作业数据主要来源于《2013安徽统计年鉴》,由于部分数据缺失,故用《2012年安徽统计年鉴》中的数据进行了选取与处理;本次作业选取的指标有X1(人均GDP/元)、X2(第三产业增加值/千万元)、X3(第三产业占GDP的比重/%)、X4(第三产业从业人员数比重/%)X5(第二产业占GDP的比重/%)、X6(总人口/万人)、X7(农民人均纯收入/元)、X8(城镇居民可支配收入/元)、X9(市区人民人均医疗保健消费支出/元)、X10(非农业人口比重/%)、X11(地方财政收入/万
2、元)、X12(规模以上工业总产值/千万元)、X13(农业总产值/万元)、X14(商品进出口总额/美元)、X15(社会消费品零售总额/万元)、X16(实际利用外资额/万美元)。运用spss19.0,首先对原始数据进行标准化处理,后经过降维进行因子分析,得到表1相关系数矩阵、表2表征值及贡献率、表3主成分载荷因子矩阵、表4主成分得分。表12012年安徽省各市有关指标相关系数矩阵X1X2X3X4X4X6X7X8X9X10X11X12X13X14X15X16X11.000X20.2761.000X3-0.3
