| Audit quality plays an important role in the accounting firm industry,and it also affects the trust of the trustee and investors in the audit report.However,in recent years,with the increase of the supervision of China Securities Regulatory Commission,the audit failure of accounting firms has been erupting,revealing that there are still problems in the audit quality control of accounting firms.In the accounting firm industry,the size of the firm is uneven,and the quality is different.Especially for small and medium-sized accounting firms,there are still many problems in audit quality control.The China Association for the Advancement of Quality Inspection(No.17)examined the quality of the accounting firm’s practice in 2017: it found that the quality control design of small and medium-sized accounting firms was inappropriate or not effectively implemented,and the audit quality control is an indispensable factor in the long-term development of accounting firms.Therefore,this paper takes XD accounting firm as a typical medium-sized firm as the object of observation,discusses the problems in the audit quality control of the institute,analyzes the causes of the problem with Luin’s theory of change,and proposes optimization suggestions accordingly.Through the literature analysis method,combined with the case,this paper points out the problems of XD accounting firm:(1)The imperfect design of the audit quality control related system leads to insufficient professional competence and eager to complete the project and neglect quality.(2)System implementation is not in place,including accepting and maintaining customer relationships and improper business practices,lack of necessary audit procedures,and lack of quality control review.Then using internal control theory and Luin’s theory of change to analyze the formation of the above problems,there are five main aspects:(1)lack of quality-oriented high-level tone;(2)the overall management of the general branch is not high;(3)The mentality of pursuing the maximization of interests;(4)insufficient supervision within the industry;(5)the homogenous competition in the industry is serious.Based on the analysis of these reasons,the article concludes with the change theory and the PDCA cycle method,and proposes four suggestions for optimizing the audit quality control of XD accounting firms:(1)Increase internal motivation,including establishing the high-level tone of the firm’s quality orientation,establishing relevant systems for quality-oriented support(such as performance evaluation and accountability),and strengthening the degree of integrated management of the general branch;(2)reducing internal resistance,Including teaching in accordance with their aptitude,cultivating the professional competence of auditors,using PDCA cycle to strengthen audit quality process control;(3)increasing external power,such as strengthening industry supervision;(4)reducing external resistance,that is,developing regionalized special expertise. |
