초록

In this study, we want to know about that degree of standard deviation of related parties transaction amount will be affect to earnings management. Standard deviation of related parties transaction amount in this study is used as a proxy of degree of fluctuation from related parties transaction amount. If CEO intend to increase net income by using related parties transaction, the amount of transaction will be increase. Otherwise CEO intend to decrease net income, the related parties transaction amount will be decrease. But if related parties transaction is normal and necessary to business, the fluctuation of transaction amount from related parties is low and even comparatively. The results of this study are as follows. First, four proxy about degree of fluctuation from related parties transaction amount has significant positive(+) relationship with absolute value of discretional accrual(Abs_DA) and performance matched discretional accrual(PMDA) as a size of earnings management. This result means that CEO increase the size of earnings management by using related parties transaction and like this intend of CEO will make high fluctuation of related parties transaction amount. Second, degree of fluctuation from related parties transaction amount has partially significant negative(-) relationship with discretional accrual(DA) and performance matched discretional accrual(PMDA). This result means that fluctuation of related parties transaction amount has no directional sign but earnings management has directional sign and therefore two heterogeneous effect mixed and distorted. To clear this uncertain results, we divided earnings management group into two parts as positive(+) earnings management group and negative(-) earnings management group. The results shows that in the case of positive(+) earnings management group, the degree of fluctuation from related parties transaction amount has significant positive(+) relationship with the size of earnings management. And in the case of negative(-) earnings management group, the degree of fluctuation from related parties transaction amount has significant negative(+) relationship with the size of earnings management. This results are all same in the study like as the proxy of earnings management are discretional accrual(DA) and performance matched discretional accrual(PMDA), and 20%, 30% of positive and negative group.
