Taking the Chinese listed shipping companies IPO from 2014 to 2018 as samples, this paper studies the impact of customer relationship on corporate performance of shipping companies IPO after being listed and verifies that customer relationship can affect corporate performance by affecting earnings management of enterprises. The result shows that customer concentration and corporate performance of shipping companies IPO after being listed are significantly negatively correlated, and customer retention and corporate performance of shipping companies IPO after being listed are significantly positively correlated; customer concentration and earnings management of shipping companies IPO in the year of their listing are positively correlated, and customer retention and earnings management of shipping companies IPO in the year of their listing are negatively correlated; customer concentration will lower corporate performance by boosting earnings management of shipping companies IPO in the year of their listing and customer retention will enhance corporate performance by suppressing earnings management of shipping companies IPO in the year of their listing.
