Abstract: Currently，aerospace products have generally been in the development stage of batch and industrialization，the development mode of the aerospace industry has been changed to paying attention to both design and manufacture from only paying attention to design. The aerospace digital workshop is the primary carrier where the digital technology is applied to the aerospace industry，the improvement of aerospace digital workshop′s digital level is essential for improving the capability of aerospace product′ s rapid design and manufacture. The aerospace company should establish the evaluation indices system of the digital workshop with aerospace characteristics，which should be divided into three levels from four aspects，including basic digital equipment construction，digital function apply，digital support system，and digital aggregate efficiency. The subordinate relations and interrelated relations among all indices should be differentiated clearly，so that all indices can include all-sided evaluation aspects，and each index can be independent as soon as possible. Based on the evaluation indices system of aerospace digital workshop，the weight coefficients of each index should be figured out by using the analytic hierarchy process，and the evaluation result relating to evaluation total mark should be ensured. Above all steps， a suit of evaluation， the guideline would be established to guide every aerospace company in evaluating its digital workshop，so that the workshop disadvantage can be found for mending. As a result，the digital degree of the aerospace digital workshop can be improved stage by stage.

Key words: aerospace digital workshop, evaluation method, evaluation indices system, promoting construction by evaluation
