evaluation systemwith multiple evaluation indexes was set up based on deeply analyzing its characteristics
and risk factors during a start-up period, and the fuzzy synthetical evaluation method was used to evaluate
the risks of an enterprise. To overcome the shortcomings of the methods to subjectively or objectively
determine the weight of indexes, the group eigenvalue method combining with the variation coefficient
method was adopted. Finally, management risk was given to showthe application of the proposed method.
