中文摘要 過去文獻對於穩健原則究竟是投機性自利效果,抑或傳遞性訊息效果,實證上仍無直接答案。以往文獻皆先假設管理投機性的存在,再直接將公司治理品質較差與會計穩健程度較小之關聯,解釋為管理當局進行投機性行為之證據。本研究之目的在探討兩項主題:(1)在控制外部經濟環境影響後,探討公司治理與會計穩健之關係,以瞭解公司治理品質對會計穩健是否產生超額影響;(2)利用公司治理品質對會計穩健產生之超額影響,分析未來長期經濟績效帶來正向利得或負向損失,以判定穩健原則究竟為投機性自利效果,抑或傳遞性訊息效果,以嚴謹分析穩健原則之資訊效果。
本研究實證結果發現:(1)從公司治理品質與會計穩健之關係中,發現公司治理品質愈高,管理當局愈會利用應計項目來增加會計穩健程度;(2)由於公司治理品質對會計穩健產生超額影響,管理當局會利用應計項目將公司內部消息傳遞給投資人,並使以長期績效作為衡量標準的股東財富呈現利得,以產生傳遞性訊息效果。
英文摘要 There is no direct evidence in the accounting literatures that whether managers make accounting conservatism for efficient shareholder value-maximization or for selfish opportunistic enrichment at the expense of shareholders. Much of the prior literature assumes the existence of opportunism and interprets an association between smaller accounting conservatism and poor governance quality as evidence that lax governance structures encourage managerial opportunism. The main purpose of this paper is to discuss two topics:(1)discussing the association between corporate governance and accounting conservatism after controlling for other economic determinants to realize whether corporate governance quality has excess influence on accounting conservatism. (2)using excess accounting conservatism due to governance to analyze if shareholders benefit or loss from subsequent future firm performance. Therefore, I can discreetly discriminate whether managerial opportunism or signaling mechanism is the dominant driver of accounting conservatism.
The empirical results are summarized as follows:(1)In the relation between corporate governance and accounting conservatism, I find managers use accruals to increase conservatism due to good governance quality. (2)Owing to the excess accounting conservatism due to governance, managers may have incentives to use accruals to communicate their private information to investors. Shareholders benefit from conservatism, perhaps because it signals managerial competence or future performance.
