We examine audit quality and audit fees of audit firms in different stages of auditor learning professional knowledge and find that in the initial stage of the process of learning knowledge, the audit quality and audit fees decrease. However, in the long run, the knowledge learning has a more obvious effect on the improvement of audit quality and audit fees, that is, the knowledge learning has a positive effect on the sustainable development of audit firms.
