An evaluation system generating a predicted value of a technology is provided. The evaluation system is primarily based on the R&D Value and the Patent Value to generate the predicted value of a technology. The evaluation system comprises a first database, a second database, an intangible asset pricing device, a factor producing device, an input device, and an analytic device The first database stores a set of stock prices of each company of a group of reference companies. The second database stores a set of net asset values, corresponding to the set of stock prices of each company of the group of reference companies. The intangible asset pricing device produces a set of intangible asset predicted values of each company of the group of reference companies according to the set of stock prices and the set of net asset values of each company of the reference companies. The factor producing device, responsive to a first predetermined condition, divides the group of reference companies into N compared subgroups, and the factor producing device also produces a set of referred factors of each of the N compared subgroups according to the N compared subgroups and the set of intangible asset predicted values of each company of the group of reference companies. The input device is for inputting a predetermined time and a predetermined cost of the technology needed for launch. The analytic device then maps the technology to one corresponding subgroup of the N compared subgroups, and then the analytic device, according to the predetermined time, the predetermined cost and the set of referred factors of the corresponding subgroup, produces the predicted value of the technology.
