| 摘 要： | 在海选省级信息化初始评价指标的基础上,采用相关分析和主成分分析定量筛选方法对初始指标体系进行变量筛选;保证筛选出的指标对评价结果有显著影响的前提下,构建了省级信息化评价简约指标体系;用22%的指标反映了99%的原始信息.最后综合各主成分构造的综合评价模型对我国31个省的信息化水平进行了实证分析,得到了较好的评价结果.

Comprehensive Evaluation of Provincial Informatization Level with a Condensed Indicators System:Based on Correlation-principle Component Analysis |
| |
| Abstract: | Based on intensive selection of the initial evaluation indicators of provincial informatization,the paper uses correlation analysis and principle component analysis to screen the indicators,and then establishes the condensed evaluation indicators system of provincial informatization by deleting indicators which have no significant impact on evaluation results.The final indicators system uses 22%of indicators to reflect 99%of original information.At last,using the comprehensive evaluation system constructed by principle components,the paper analyzes empirically the informatization level of 31 provinces in China and achieves a good effect. |
