基于主成分分析法的广东省制造业竞争力研究

A study on the capacity of competition of manufacturing industries In Guangdong based on the principal component method

通过选取相关指标,利用主成分分析法分析了广东省28个制造业的竞争力状况,发现广东具有竞争优势的产业主要以医药化学工业、仪器仪表、电子信息产业、电气机械及器材制造业等资本、技术密集型产业为主;竞争力比较弱的产业主要是一些资源依赖性产业,比如黑色金属、有色金属等产业;重点扶持的汽车业、造船业和造纸业现阶段竞争力并不强,需要促进其竞争力提高。

This paper choices some relevant indexes to analyze the capacity of competition of 28 manufacturing industries in Guangdong through the application of the principal component method, and find out that the competitive industries are mainly capital-concentrated and technology- concentrated industries such as medicine& chemistry industry, instrument manufacturing industrie,IT,electric machine & equipment manufacturing industry in Guangdong. Resources-relied industries such as ferrous metal process industry, color nonferrous metal process industry are not competitive. The study result also indicates the key industries of Guangdong such as auto industry, shipbuilding industry and papermaking industry are not very competitive. Some measures should be made to promote the capacity of competition of these industries.
