This paper puts forward a new dynamic approach to evaluate Enterprise Resource Planning (ERP) benefits. In this paper, essential financial indicators are used to calculate the effect of sample enterprises which have executed ERP implement for more than 5 years in China. The method we proposed in this paper is based on the fuzzy statistical analysis and fuzzy rule based decision support system. According to the yield study, we find that it is different from our expectation, there is a positive impact in the first few years after the ERP implement; but then, the trend of the ERP performance will be downside to be negative as time goes by, it is surprising, we think it may be caused by marketing environment changes; at last, the trend of the ERP performance will be stable and a little rise. We think the trend fits the actual situation more, and prove the effectiveness of our approach.
