| Abstract: | Considering the expected return being fuzzy number, this paper set up a mean - variance portfolio investment model for China''s endowment insurance fund by using possibility mean and possibility variance as the expected yield and risk of portfolio. Using lingo software for numerical analysis, the results suggest that the proposed model has a certain practical application value. |
