This article is based on traditionally intrinsic value assessment model. We employed the assumption on the differences in future increase rates of companies, taking into account of the expected Economic Value Added (EVA) discount and the capital investment, to establish a high increase model, a two-stage EVA discount model and a three-stage EVA discount model for the intrinsic value assessment. Those models eliminate the great fluctuation of free cash flow in calculating the capital expenditure by setting aside the cash flow of the companys investment in the year and considering only the capital cost. This method needs only to assess the EVA flow in different year in probing the intrinsic value of a company, thus give more consistent conclusion than conventional methods.
