  【主题】：Is credit rating a rubber stamp in China?  
  【摘要】：The paper aims to study whether credit rating can affect corporate bond-issuing cost. It is commonly believed that rating shopping under current institution inflates debt rating, but simple OLS analysis shows that good credit rating can significantly corporate bond–issuing cost. An interesting dilemma arises: if the OLS result is credible, then the market will be at least partly inefficient. To tackle potential endogeneity problems, we use the competitiveness between rating companies as an instrument for credit rating. Our instrument-base regression shows that credit rating has no statistically significant effect on bond-issuing cost， and compared to OLS result, its economic effect also becomes weaker. So, we conclude that credit rating inflation does not cheat the market, and it only makes credit rating as rubber stamps.
