This paper investigates credit allocation before and after the 2003 banking system reform in China. We find that relationships between earnings quality and new short-term loans, long-term loans and total loans in listed companies changed significantly after the banking system reform, especially in stateowned listed companies. Further investigation shows that due to the influence of rent-seeking, banks have eased the earnings requirements of non-stateowned listed companies. These findings enhance our understanding of the economic consequences of the banking system reform and of credit discrimination under the new regime.
