 note = {P(論文), Until now the efficiency of company management has usually been evaluated byusing accounting methods based on financial statements. However there is the limitation that operational and financial factors in the statement cannot be dealt withsimultaneously.  A new method of analyzing efficiency is proposed by utilizing DataEnvelopment Analysis（ DEA）which is useful for dealing with multi-dimensional factors. The validity of this method is tested by simulation using data from abusiness management game.},
