The DEA safety accident management evaluation method need no prior stating of evaluation indexes weight and it can perform a quantitative analysis for input redundancy and output deficiency. We applied DEA model in the relative evaluation analysis of construction safety performance in Chongqing. The result shows that the redundancy of death number is comparatively higher than the redundancy of construction accident number. Therefore, the construction safety accident management performance of Chongqing needs to be improved. We proposed a quantitative evaluation method to measure the construction safety accident management performance and provided a new process and idea to evaluate the safety performance.
