摘要

DEA method applied in analyzing stock investment value has just begun. There are 5 papers found in Chinese Journal Net. Because the selected indexes in them are comparatively less, they could not fully reflect the financial state, profit capacity, management efficiency, cash flow and growing up in companies. Though the two models were used in the papers mentioned above, the C{sup}2R model and C{sup}2GS{sup}2 model could not embody the preference of investor. As a result, the effect is not entirely content. In the article, the new developments of DEA are applied, Input and output index system reflecting fully listed companies' stock investment value is constituted, and C{sup}2WH model is used to reflect investors' preference.

Input-output efficiency of listed companies and whether it is technical efficiency or scale efficiency are appraised. The approaches of improving listed companies' management efficiency and stock investment value are indicated.
