基于主成分分析的陕西科技竞争力实证研究

由于主成分分析是一种实用的多元统计分析方法,能消除样本指标之间的相关性,在保持样本主要信息的前提下,提取少量具有代表性的主成分。所以,近年来在多指标评价上得到越来越广泛地应用。因此,文章采用主成分分析方法对陕西科技竞争力问题加以分析,其最终目的是落实科学发展观,促进陕西科技进步,推动陕西社会、经济的可持续发展。研究结果表明,陕西的科技竞争力综合水平得分为负值,这说明陕西的科技发展水平低于全国的科技整体发展水平。这显然与陕西教育大省、科教大省的地位不匹配。

Empirical Research on Science and Technology Competitiveness of Shaanxi Province Based on Principal Components Analysis

Because the principal components analysis is one of the practical multi-dimensional statistical analysis methods,it can eliminate the relevance between the sample targets and extract the representative principal components while keeping the main information of the sample.Therefore,in recent years,it has found its wider uses in the multi objective appraisal.This article analyzes the issue of Shaanxi science and technology competitiveness by using the principal components analysis method for the purpose of im...
