摘要


本研究探討公司產品市場力及產業競爭性對營業活動操弄程度之影響。從美國上市公司實證結果顯示營業活動之操弄的確與產品市場力及產業競爭性息息相關。特別地,我們發現的證據顯示產品定價能力較差的公司,在銷貨與裁量性支出上出現較多的操弄。 另一方面,實證結果提供的證據也顯示,愈是競爭產業的公司愈會從事銷售活動與生產活動的操弄。異常營業活動與產品市場力及市場競爭性之顯著關聯強化經理人實質盈餘管理之意涵。

並列摘要


This study explores the effects of product market power of firms and industry competitiveness on the degree of real activity manipulation. The empirical results, from U.S. listed corporations data, show that the real activity manipulation is associated with not only product market power but also industry competitiveness. Especially, we find evidence suggesting that firms with inferior product market pricing power appear more manipulations of sales and discretionary expenditures. Our empirical result, on the other hand, also provides the evidence that firms in more competitive industries engaged in greater manipulations on sales and overproduction. The evidence that abnormal activities are significantly associated with product market power and industry competitiveness emphasizes the direct implication of real earnings management.
