The empirical research in em forthers the acaden1ic thoughts of accrual - basis accounting, hastens the development of generally accepted accounting principles, and enriches the research measures in empirical accounting lots of literatures on em have been reported rece11tly however, researcheres have n ' t reached the consensus in most issues in this fieid much of the controversy over the interpretation of the literature ' s tindings is due to the extensive use of aggregate accruals models that mostly origil1ated from jones mode1 given the limlted theory, we have of how accruals behave in the absence of discretion, the task of identifying and controlling for potentially correlated o111itted variables is daunting indeed an alternative to study aggregate accruals is the 111ethodology for identifying earnings management developed by burgstahler and dichev ( l997 ) based on the distribution of earnings after management however, this measure is flawed by its silence about the form and extent of earnings management my dissertation intends to bridge the traditional aggregate accruals models and the new earnings distribution method, which is the first aim of this paper there is no doubt that earnings management is more rampant in china when compared with what has been documented for the west, since china ' s accounting standards are much too incomplete to of lbr clear guida11ce on many accounting transactions
