| In January 2014, the Ministry of Finance formally promulgated the accounting standards for enterprises No.39-fair value measurement, and puts into practice in the same year in July. The use of fair value measurement relys largely on the accountants’ estimates and judgements, and the fair value measurement standards formulated by the principle oriented concept significantly improve the professional judgement space and the uncertainty of accounting information. When using fair value, accountants may be affected by many factors, which leads to the deviation of judgement, and obvious judgement deviation leads to accounting professional judgement risks, finally making the fair value measurements inconsistent with objective accounting facts. Therefore, this paper tries to research the related issues of accounting professional judgement risks of fair value to improve the fair value accounting information quality.Firstly, this paper analyzes the relevant concepts of accounting professional judgement risks of fair value with normative research method, on the basis of Lewin’s behavior formula, discussing the impact of the influencing factors of accounting professional judgement risks of fair value, such as subject factor, object factor and environmental factor. Secondly, the paper puts the accountants who used fair value measurement as the object of investigation, through the way of questionnaire to collect data for empirical analysis. With factor analysis, it founds that the influencing factors of accounting professional judgement risks of fair value can be classified as five factors:values of accountants’factor, cognitive level of accountants’factor, authorities’intent factor, object factor and environmental factor. Besides, with individual difference analysis, it founds that accounts with different characteristics basically agree with the importance of most of the influencing factors in the questionnaire, and there are only a few differences. Finally, the paper puts forward the control measures of accounting professional judgement risks of fair value, based on the analysis of influencing factors, which are improving the comprehensive quality of accounting behavior subject, optimizing market conditions for fair value measurement, and strengthening internal control and external supervision. |
