total assets through years before and after listed,and alse the
relationship between financial conditions and earnings changes.
Research data includes 82 firms newly listed in Taiwan Stock
Exchange from 1990 through to 1993, and the observation period
is those years which begin with 3 years before listed 2 years
after. Tempirical analysis are performed in the following
ways: First, the individual accruals of sample firms are
compared before and after listed to test their equality, Second,
the relation between discretionary accruals and performance
after listing are examined by Multiple regression. The
result of this study are as follows: 1.The allowance for
inventory loss and bad debt expense do not decrease before
listed, neither increase after listed period. 2.The
financial acccounts-cash, account receivable, and inventory do
not increase before listed, and do not decrease after listed,
either. 3.The empierical result shows no obvious
relationship between the return on total assets and individual
