Bid Evaluation Research of Construction Project Based on Two-Stage Entropy Weight

This paper defines the evaluation index system of construction project first, on this basis, uses the two-stage entropy weight method to determine the weight, thus avoids the faults of expert grading with a subjective attitude, at the same time, it´ s a more objective method than one-level entropy weight, then, the article uses an empirical analysis describe the application of two-stage entropy weight method, finally, the article gives several suggestions.
