|
摘要
选取2013—2017年47家中药上市企业的12项指标,构建企业竞争力评价体系。首先采用全局主成分分析法将12项指标聚成4个主成分,并分别命名为规模能力、盈利能力、成长能力和技术创新能力,并计算企业竞争力得分;其次在企业竞争力得分基础上,运用Q型聚类分析法将企业分成4个类型,然后运用动静结合的方式,从静态、动态角度分别分析4类企业的发展状态;最后得出相关结论和建议,让企业有的放矢地制定发展战略。
This paper selects 12 indicators of 47 Chinese materia medica(CMM) listed companies from 2013 to 2017, and builds an enterprise competitiveness evaluation system. Firstly, the global principal component analysis(GPCA) method is used to aggregate12 indicators into four principal components, which named as scale capability, profitability, growth ability and technological innovation ability, and calculate the competitiveness score of the enterprise. Secondly, the Q-type cluster analysis method is used to divide the enterprise into four echelons based on the competitiveness score of the enterprise, and then use the combination of dynamic and static to analyze the development status of the four types of enterprises from static and dynamic perspectives. This study finally drew relevant conclusion and suggestions, providing reference for the companies making a targeted development strategy.
