Abstract: The authors of this paper, by making researches on the income present value method for appraisingmineral resources assets using time series analysis theory and asset pricing theory, establish a dynamic model of forecasting the future net incomes of the mineral resource assets to be appraised, and put forward a method for calculating the history data of discount rates. Based on that, they build a dynamic model for forecasting the future discount rates, which is similar to the dynamic model for forecasting net incomes. These models and method lay a foundation for extending the static income present value method into the scientific and practical dynamic income present value method.
