首度上市公司盈餘管理與股價關聯性之研究張至善, Chang, Chih-Shan Unknown Date (has links)
本研究目的在探討首度上市公司上市前,管理當局因存在達到上市審查條件與提高股票承銷價格的動機,使得首度上市公司上市前運用可能利用盈餘管理提高財務報表盈餘數字。本研究藉由選取民國82年初至民國86年底首度上市公司共136家,其中包括電子類股42家,非電子類股94家,以統計配對樣本Z檢定與複迴歸分析方法,進行首度上市公司之盈餘管理與股價關聯性實證研究。本研究獲得的結論如下:
1.就民國82年初至民國86年底間首次上市公司上市前應計項目呈正向增加的現象顯著,證實首次上市公司上市前有盈餘管理現象。
2.不論電子類股或非電子類股之首次上市公司上市前以增加應計項目,進行盈餘管理的現象並未呈顯著的不同。
3.股市多頭或空頭走勢,並未在首次上市公司於上市前增加應計項目變動的現象產生顯著的差異。
4.首次上市公司上市交易的前十個交易日股價累積報酬明顯為正值,同時又高於同期間大盤指數的累積報酬率。(本指數係採不含金融類股的加權股價指數作為比較基礎)
5.上市交易的前十個交易日股價累積報酬率,與上市前應計項目變動關係不顯著,而與上市前二年至上市前一年的現金流量變動呈正相關。

銀行業的競爭程度及會計盈餘的時效性、穩健性之分析呂美慧, LU, MEI-HUI Unknown Date (has links)
本文內容主要可分為三大部分,第一部份是「本國銀行業逐年的競爭程度及其變化之分析」,主要是以Panzer-Rosse模型評估銀行業的競爭程度,實證結果顯示1996至2000年每年的金融市場處於壟斷性競爭或完全競爭,在考慮銀行業務差距頗大及極端值存在的可能之下,2001和2002年的銀行業為壟斷性競爭。相較於1996至2000年,2001至2002年銀行業的競爭程度有降低的現象。
第二部分是「銀行業的競爭程度與利息收入佔總資產比率之關聯性分析」,本文延伸Panzer-Rosse模型,以分量迴歸法取代傳統最小平方法,發現排除規模效果的影響下,位於利息收入的條件分配愈左端(即利息收入佔總資產比率較低)的銀行,其所處之金融環境競爭程度愈高。此外,亞洲金融危機受創最嚴重的五個東南亞國家,自金融風暴發生至2004年,位於經資產標準化的利息收入分配左端、或右端、或中間的銀行在各個國家雖遭遇不同的競爭環境變化,不過,平均而言,所有銀行面臨的競爭程度皆獲得改善。
第三部分是「以分量迴歸法分析會計盈餘的時效性與穩健性」,實證結果顯示會計盈餘對好消息認列的時效性和對壞消息認列的穩健性會受企業當期的盈餘水準所影響。若企業當期的盈餘水準愈差,則會降低其盈餘的時效性,但是會提高其盈餘的穩健性。相反地,若當期的盈餘水準愈高,則會提高其盈餘的時效性,但是會降低其盈餘的穩健性。 / There are three issues in this dissertation. The first one is to analyze the yearly degree of competition and its variation in Taiwan’s banking industry with the Panzer-Rosse model. We find that the markets over the period 1996-2000 were characterized with monopolistic competition or perfect competition, while the system was characterized by monopolistic competition in 2001 and 2002 after we take into consideration the possibility of outliers. Furthermore, the results also suggest that the competition has declined in Taiwan’s banking industry.
The second topic is to investigate the relationship between banking competition and the ratio of banks’ interest revenues to total assets. The results show that while the ratio of bank’s interest revenues to total assets is lower, the bank faces a more competitive market. Moreover, competitive pressures have been improved for banks with different levels of interest revenues over total assets in East Asia after the financial crisis occurred in 1997.
About the final issue, we try to find whether firms’ contemporaneous earnings affect the timeliness and conservatism of accounting earnings and their relationship. Our results show that the degree of timeliness and conservatism of accounting earnings are relevant to the level of earnings. Specifically, firms with poor earnings will decrease their earnings in recognizing good news but increase the level of conservative accounting. On the other hand, the level of conservative accounting is a decreasing function of earnings while the timeliness in recognizing good is increasing in earnings.
