【Abstract】 Taking the listed companies in Shenzhen Stock Exchange from 2012 to 2020 as research samples, the paper empirically analyzes the impact of institutional research on corporate earnings management. The study finds that there is a U-shaped relationship between institutional research and earnings management.
