摘要

Investors of listed Chinese medicine companies is the community. How to correctly use the information to evaluate the Chinese medicine listed companies' performance scientifically and provide reference information for all stakeholders and corporate managers, is a problem that become more and more urgent and important in theory and reality. This paper firstly sets up an input-output mode to appraise the relative effectiveness of Chinese medicine listed companies by DEA method, and implements the discretization process to make the model results discrete. Secondly, we make use of rough set to give synthesizing evaluation score to every object through the dispersed data. The integrated use of DEA and RST can fully reflect the input-output character of operational efficiency and through the established model we can get a more reasonable result without artificial influence.
