| 摘 要： | 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;运用主成分分析方法对国内30个省、市、自治区的装备制造业的竞争力进行综合比较,通过对装备制造业7个大行业和209个小行业19项主要经济指标的分析,认为陕西装备制造业具有一定的规模竞争力和综合竞争力,但是比东部的江苏、广东等省份竞争力弱;研究结果还表明,陕西有47个小行业综合竞争力在全国排名10位以内,可以通过大力发展这些优势小行业,从而提升陕西装备制造业的整体竞争力。

| Abstract: | Because the principal components is a kind of practical multi - dimensional statistical analysis method, it can eliminate the relevance between sample targets, under the maintenance of main information of samples, a few representative principal components can be extracted. Therefore, this article utilizes the principal components analysis method to compare competitive power of equipment manufacturing industry among 30 provinces,cities, autonomous regions, through the analysis of 19 main economic indicator of 7 large professions in manufacturing industry and 209 small professions it turned out that Shanxi equipment manufacturing industry has certain synthesis competitive power, but much weaker than those provinces in the eastern part, such as Jiangsu, Guangdong.The findings also indicated that, Shanxi has 47 small professions whose syntheses competitive powers have been place within 10 in the country, through vigorously developing superiorities of small professions to promote the overall competitive power of equipment manufacturing industry of Shanxi Province. |
