Abstract: As an important part of cost management, cost management performance evaluation plays an important role in guiding the forward development of project cost management. Based on the current construction project management system and combined with relevant specifications, an evaluation index system was established on the basis of collecting construction project cost management data from five aspects: the overall performance of cost management, process performance, direct cost management performance, indirect cost management performance and other cost management performance. The index weight was determined by the method of entropy weight and the results were analyzed. The improved extension theory was used to establish the performance evaluation model, which was verified by a road project. The results show that the proposed performance evaluation model not only quantitatively evaluates the level of construction cost management, but also combines with time limit, quality and safety to help improve the level of project management. In the later application, with the accumulation of enterprise project data, the model can be optimized by ifself.
