Taking 2012—2018 A-share listed companies as the research object,the value of the core competence information disclosure in the annual report is empirically tested.The empirical results show that:(1)The length of the company’s core competence information disclosure has nothing to do with the analyst’s earnings forecast accuracy,in contrast,the specific information in core competence information disclosure is related to the accuracy of analysts’earnings forecasts.After a series of robustness tests,the above relationship still exists;(2)Cross-sectional analysis shows that the core competence information disclosure for non-state-owned enterprises and enterprises with strong corporate governance is more conducive to improving the accuracy of analysts’earnings forecasts;(3)It is further found that the core competence information disclosure is related to the company’s earnings, therefore, it is conducive to improving the accuracy of analysts’earnings forecasts;(4)After considering other textual features of the core competence information disclosure,it is found that the accuracy of analysts’earnings prediction is related to the similarity of the core competence information disclosure of the company and other companies in the same industry,but not related to the similarity of the core competence information disclosure between the current year and the previous year.
