In this paper, using Non-Parametric Method and DEA(Data Envelopment Analysis) method, measures technical efficiency, pure technical efficiency and scale efficiency of 15 commercial banks including Chinese state commercial banks and the stock commercial banks in 2000 to 2009. For the DEA model, we put the membership, fixed assets and equity capital as input variables; and the loan, operating profit and net profit as output variables. Overall technical efficiency has been improving, and technical efficiency of commercial banks and stock commercial banks are also constantly improving, but the efficiency of stock commercial banks are much higher than the efficiency of Chinese state commercial banks, and the main factor affecting the technical efficiency is scale technical efficiency.
