It introduces China pharmaceutical industry's characters and problems and then analyzes influence factors from the macroscopically, interspaced and microscopically views. Chapter four is the empirical research part in this paper. It introduces the principal of appraisal index and the choosing of the indexes. Then it introduces the building of model and its disposal method in Spss. To get a clear view of principal components analysis the paper analyzes the differentiate and connection between PCA and factor analysis. In this basement, the paper introduces the disposal process and results of the model. The paper then improves the model with entropy right method to eliminate the portrait diversity of data. To validate the model's stability, the paper makes a significance test of the four results.

第四章是本文的实证研究部分，首先介绍了评价指标选取的原则和指标的确定；然后介绍了模型的构建及其在spss中的处理原理，由于主成分分析法不能在spss中直接实现，且其原理和操作都易与因子分析相混淆，所以本节首先分析了主成分分析法和因子分析法的区别和联系，在此基础上描述了怎样在spss的因子分析的基础上利用主成分分析法进行投资价值评价模型的数据处理；然后介绍了模型的数据处理过程和输出结果，随后利用熵权法对模型做了进一步改进，消除了数据间的纵向差异性，并对改进前后的输出结果进行显著性检验，以验证模型的稳定性。
