基于主成分分析法评估上海世博对就业的影响

考虑影响上海就业的6个主要指标即资本形成总额、消费者物价指数（CPI）、人口数量增长率、人口密度、经济增长率和人口总数量。为了把问题简单化,运用主成分分析法把上海地区1996-2009年的6个指标值列成14行6列的原始数据矩阵A,并结合原始矩阵A的数据,利用Matlab求出原始矩阵的特征值、特征向量、贡献率及积累贡献率,并根据所求出的值进行主成分分析,从影响上海就业的6个指标中综合出对上海就业影响较大的影响因子指标。结果表明,上海世博极大促进了上海的就业和创业。

Assessment of Impact of Shanghai World Expo on the Employment Based on Principal Component Analysis

Considering the simplification and the main six indexes influencing the Shanghai employment(gross capital formation,consumer price index(CPI),population growth,population density,economic growth,the total number of the population),the raw data matrix A with 14 rows and 6 columns has been constructed from the values of the six indexes of Shanghai from 1996 to 2009 by applying the principal component analysis.Furthermore,Matlab is used to calculate eigenvalue,eigenvector,contribution rate,and the contribution...
