Abstract:
This paper estimates and compares efficiency performance of 32 commercial banks in Vietnam during 2001–2005, as well as identifies possible factors determining such efficiency performance. Efficiency is measured by a data envelopment analysis (DEA) model and super-efficiency measure through a slacks-based model (SBM) under the assumption of variable returns to scale (VRS). We find that there were a small number of efficient banks, and there would be room for these banks to improve their production efficiency. Moreover, in comparison with small banks, large banks do not guarantee high super efficiency scores. The results from a Tobit regression model provide such interesting findings as negative impact of state ownership, positive influence of bank size and market share, but no impact of labor quality.
