| Abstract: | The Markowitz portfolio model was put forward. That is, when investors are making decision, they always hope to obtain maximum yield instead of minimum venture, or the investors often do their best efforts to reduce venture in front of definite yield. The hypothesis conditions of Markowitz portfolio model were analyzed, such as market efficiency,venture measure, parameter estimate time-availability, zero bargain fee, and so on. The main problems about Markowitz portfolio theory in China were put forward and a new idea on optimal portfolio investment model improvement was expounded. |
