Then, this paper empirically tested the validation and predictive accuracy of different var risk management model in the domestic financial market. finally, with the analysis of modem financial risk management development trend and the current domestic financial risk management situation, this paper made a prospect for the application of this model in the construction of domestic financial risk management system. through the analysis, the main conclusions are as follows : ( l ) the traditional mean - variance model is the special example of the portfolio selection based on the var risk management model for the case that the returns of the portfolio are assumed to be normally distributed ; compared with the mean - variance model, the var risk management model is more comprehensive and accurate in the measurement of the portfolio risk, so based on the var model, the investors can allocate the asset more effectively. ( 2 ) the var risk management model can provide the timely and comprehensive risk information for the top risk manager, so it is very helpful to the improvement of total risk management efficiency. ( 3 ) based on the var model, the raroc performance valuation approach can reflect the real performance of the portfolio manager and provide the coherent standard for the allocation of risk limitation and the construction of the incentive compatibility constraint mechanism in the financial instiutions
