Abstract

Earning management (EM) exists as an impact of accrual basis. Based on Agency Theory,
earning management problems can be reduced by self-control of corporate governance
(CG) mechanism. The purpose this study is to analyze the difference of the CG mechanism
and EM between those in accordance with syari’ah index (JII) and conventional index
(LQ-45). Samples consist of 89 and 39 companies listed in Bursa Efek Jakarta (BEI) from
2004 to 2007. The result indicates that the EM practice on the conventional index (0.4027)
is higher than syari’ah index (0.2337). The regression analysis shows that the board of
commissioner size has positive impact on the EM significantly in main model and conventional
index model, but not in shari’ah model. The managerial ownership has negative
impact on the EM significantly in conventional index model, but not in syari’ah model.
Keywords: earning management, corporate governance, impact, conventional index, syari’ah
