Research On Disclosure Of Key Audit Matters In New Energy Power Battery Industry

In order to solve the problem that users have limited access to information in traditional audit reports,China added a number of audit standards in 2016,including standard 1504——Key audit matters.The promulgation of standard 1504 is a major improvement in the audit work,which is conducive to increasing the value of the audit report and enabling investors to obtain more information from the audit report.Based on this background,this paper selects the new energy power battery industry for research by using quantitative research method,industry research method and case analysis method,analyzes the overall situation of the disclosure of key audit matters in the industry,summarizes the problems existing in the disclosure of key audit matters in the industry since the implementation of standard 1504,and puts forward improvement suggestions from many aspects from the perspective of certified public accountants.This paper is divided into the following parts.Firstly,it introduces the development status of new energy power battery industry,studies the literature on key audit matters at home and abroad,and expounds the concept and basic theory of key audit matters.Then,taking 136 audit reports of 35 listed companies in the new energy power battery industry from 2017 to 2020 as the research object,this paper first analyzes the industry characteristics and audit focus of the new energy power battery industry,and considers the recognition of power battery revenue,impairment of inventory The provision for impairment of accounts receivable and the recognition of intangible assets are matters that auditors should focus on and implement adequate audit procedures in the process of auditing enterprises in this industry.Then,this paper makes a detailed statistics on the key audit matters disclosed by these 35 listed companies from 2017 to 2020,and analyzes the disclosure status in detail from the aspects of the types of matters disclosed.On this basis,this paper analyzes the information content of key audit matters disclosed by the industry from four perspectives: the characteristics of quantity,form and length,the types of firms hired and the types of audit opinions issued.Further,taking Guangzhou Penghui energy as an example,this paper specifically analyzes whether the disclosure characteristics of specific enterprises in the industry for key audit matters can reflect the industry characteristics,analyzes the disclosure characteristics of their matters,and then analyzes the information content,it is considered that the reason why the enterprise determines key audit matters at the time of disclosure is that there is less incremental information,and the homogeneity of audit procedures for key audit matters is serious.Finally,it comes to the conclusion that the key audit matters disclosed by certified public accountants do not pay attention to the matters related to the recognition and impairment of intangible assets,do not fully reflect the industry characteristics,the matters depend on previous years,and the form is lack of conclusive expression.In order to solve these problems and further improve the information content of audit reports,from the perspective of certified public accountants,certified public accountants should strengthen communication with management,improve the quality of audit work,and improve the disclosure of key audit matters.For these three suggestions,this paper further puts forward how to do it.The contribution is to select the new energy power battery industry for research.There has been no literature on the key audit matters of this industry before.Taking the new energy power battery industry as the research object,this paper can provide new ideas for the audit work of accountants.
