Empirical Research On Internal Control And The Quality Of Preliminary Earnings Estimate

Preliminary earnings estimate is an institutional innovation in the disclosure of the annual report of listed companies in 2004,aiming to improve the timeliness and fairness of accounting information.In recent years,the frequent occurrence of accounting information distortion events has exposed the unreasonable shareholding structure of listed companies and the defects of internal control and other problems,which have misled investors' decision-making,and undermined their confidence in investment.Facing the uncertain market environment in the future,it is also crucial to improve the quality of preliminary earnings estimate and promote the healthy development of the capital market.Based on this,this thesis mainly studies the relationship between ownership structure,internal control and the quality of preliminary earnings estimate.Firstly,this thesis sorts out the relevant literature on ownership structure,internal control and the quality of preliminary earnings estimate.Secondly,the concepts of ownership structure,internal control and the quality of preliminary earnings estimate,as well as information asymmetry theory,corporate governance theory,principal-agent theory,stakeholder theory are elaborated.Then,analyzes the impact mechanism of internal control and the quality of preliminary earnings estimate,and the operation principle of the adjustment effect of ownership structure on the two,and proposes corresponding research hypothesis.Finally,constructs four regression models,and makes an empirical analysis of sample data with SPSS 22 statistical software.The study shows:(1)internal control and the quality of preliminary earnings estimate clearly shows a positive correlation;(2)compared with state-owned enterprises,the relationship between internal control and the quality of preliminary earnings estimate is more significant in non-state-owned;(3)management shareholding enhances the relationship between internal control and the quality of preliminary earnings estimate;(4)institutional ownership weakens the relationship between internal control and thequality of preliminary earnings estimate.According to the conclusions of thesis,some suggestions for improving the internal control and optimizing the shareholding structure to improve the quality of preliminary earnings estimate of SEM and GEM board companies are put forward,and the limitations and future research prospects of thesis are proposed.
