The study looked at how Chinese companies manage their earnings, analyst forecasts, and credit ratings when issuing bonds. They found that companies sometimes manipulate their earnings to get a better credit rating for their bonds.

In fact, earnings management and analyst forecasts can actually work together to influence bond credit ratings. This information can help regulators and stakeholders make better decisions.
