| dc.description.abstract | This research is to regard the opening in the branch of one new bank as the theme of studying, main branch’’s business efficiency change of opening in order to analyse this bank of purpose , in order to understand that branch’’s business efficiency that this bank each opens behaves , regard running the reference that the management tactics of range upon range of mountains of the bank stipulate now as. This research materials source is taken from this bank trip affair and report the materials, 53 of the whole province of bank will open in the branch as the research object from 2004 to 2005, adopt and estimate the efficiency value of the bank at three stage DEA models, the first stage tries to get the primitive efficiency value before adjusting with the firsthand infor mation , adjust the environmental parameter again at the second stage, in order to make four kinds , such as amount , facing the trading volume of the cupboard , electronic trading volume of bank , business unit attribute ,etc. as external environmental parameter; Also adjusting the random influence on efficiency value of error at the same time, the input amount after adjusting takes the place of and enters DEA again, can get the efficiency value of adjusting the last the third stage and change using to probe into the efficiency value of the bank .
The real example result shows, through to the adjustment of environmental parameter and random error one, the apparent difference all exists to worth the first stage and the third stage in efficiency , show the environmental parameter with interferes a behavior that really influences the efficiency of the bank at random. After changing, grow the influence of parameters and random error except already going in efficiency value of the third stage income , can open the efficiency of management of the branch on behalf of this bank the whole province. Making use of the third stage efficiency value tried to get to estimate the efficiency value change t hat the whole province of bank opens before and after the branch influences, make bank administrator can to open actual business efficiency of the branch make correct judgement decision and deal in the minute hand each. | en_US |
