This paper applies an innovative DEA (Data Envelopment Analysis) model, the Inverse -convex model, in order to investigate the technical efficiency of a representative sample of Chinese banks. The banks are ranked according to their efficiency over the period 1998-2008. The results paint a mixed picture of the Chinese banks' performance. The influence of firm size and ownership on bank efficiency is not observed. However, the study shows that overall efficiency improved over time, especially after the entry of China into the WTO. Policy implications are derived.
