| Abstract: | Data envelopment analysis was applied to determine relative efficiencies of state-owned and joint-stock banks in Chongqing, P. R. China, during the years 1996 to 2000. We found that state-owned banks have low levels of efficiency when compared with joint-stock banks, but some joint-stock bank branches have low efficiency scores. Efficiency difference testing by using the Mann-Whitney rank order statistic indicates that the efficiency gap between state-owned and joint-stock banks is insignificant, which is characteristic of regional banks. We also presented some factors that may affect bank efficiency, and offer suggestions to improve bank management and efficiency. |
