| 摘 要： | 在设计区域创新能力评价初始指标体系的基础上,采用基于主基底分析的变量筛选方法对初始指标体系进行变量筛选,构建了区域创新能力评价体系的简约变量集合,在保证原始变量信息损失尽可能小的前提下,排除所有的冗余信息,避免了变量之间的多重相关性;再利用主成分分析对简约变量集合进行二次降维,构建综合评价模型,对我国30个地区的创新能力进行排序及分析评价,得到了较好的评价结果。

| Abstract: | Based on the design of the original evaluation index system of regional innovation capability,the paper selects variables by a variable selection method based on principal basis analysis,to condense the variable set for evaluation of regional innovation capability.The adopted method selects information effectively from the large-scale variable set,while excluding all the redundant variables and reduplicate information on the promise that the loss of original information is minimized.Then principal component... |
