本文主旨主要是探討家族企業對盈餘股利相對資訊性之影響。其研究方法是透過Between-sample 及 Within-sample測試。實證結果發現,家族企業較具有盈餘資訊性,而非家族企業相對較具有股利資訊性。此一結果顯示出家族企業較重視盈餘品質。本研究又進ㄧ步測試發現,相較於非家族企業,家族企業會產生較高的盈餘資訊性主要是來自於創始CEO與後裔CEO。除此之外,也發現當家族企業的股權無偏離時,相較於非家族企業則較具有盈餘資訊性。最後,當企業加入了機構投資人與非家族內部人持股,其此兩種外部監控機制對於家族企業仍會提升盈餘資訊性。 This paper examines the impact of founding family ownership on the informativeness of earnings relative dividend by using between-sample and within-sample tests. We empirically find that family firms exhibit greater earnings informativeness and lower dividend informativeness as compared to non–family firms. These findings suggest that founding family ownership is associated with higher earnings quality. In addition, we find that, compared to non–family firms, family firms with funder CEOs and descendant CEOs and without separation of control and cash flow rights are associated greater earnings informativeness. Finally, the results also indicate that, after controlling for founding family ownership, concentrated institutional ownership and non–family insider ownership have incremental power in explaining earnings informativeness.
