Research on the Impact of Information Technology on the Construction of Intelligent Engineering Audit Systems in Accounting Firms

With the application of intelligent technology in audit work, the engineering audit system has ushered in new development opportunities, prompting major accounting firms to actively explore the construction and application of intelligent information technology in engineering audits. To this end, this paper, from the perspective of engineering audits conducted by accounting firms, takes the five stages of engineering audits in accounting firms as the main thread to study the overall framework of the intelligent engineering audit system and the specific design of each stage. It also analyzes the application of the intelligent engineering audit system through practical cases. The application results show that compared with traditional manual identification, efficiency has been improved by 80%, the average audit reduction rate per project for auditors has increased by $\mathbf{2 0 \%}$, and the average audit duration has been reduced by $\mathbf{3 5 \%}$.
