The good quality of the implementation of public construction procurement cases has a positive influence on the improvement of the country's competitiveness and directly affects the overall governance effectiveness. Therefore, this study uses dynamic data envelopment analysis to evaluate the business performance of firms. We aim to establish a grading system, which propose to add performance grades to the basic qualifications of bidders, or invite firms with good performance in the initial stage of bidding in order to reduce the impact of bad factors at the initial stage of the purchase. In addition, through benchmarking analysis, and to provide the direction for each firm to improve the relative efficiency value, understand how to adjust the resource allocation to improve its own operational performance, and increase the possibility of participating in government agency purchases.
