Dotcom公司更名之長短期效應 / Long-term versus short-term effects of dotcom name changes

吳廷芸, Wu, Ting Yun Unknown Date (has links)
本文研究自1997年至2007年,dotcom公司更名之長期與短期宣告效應,樣本包括名稱增加dotcom或剔除dotcom的兩類公司。過去文獻指出dotcom公司更名在-30天到+30天期具有顯著為正的累積超額報酬。與以往文獻不同,我們關心dotcom公司更名帶來的正報酬是否能持續,抑或宣告後的效果終將轉為負報酬,減損股東財富。實證結果顯示,雖然在事件日出現顯著3.14%的正累積超額報酬,但120天與360天事件窗口累積超額報酬均為顯著負值,分別為-55.52%與 -156.09%,所以dotcom公司更名的妝飾效果(cosmetic effect)為暫時的現象。故在長期,投資人若在網路熱潮時期買進新增dotcom於其名稱的公司的股票,損失很可能會隨著時間而擴大。此外,我們也發現更名公司的基本價值(fundamental values)在更名的前後兩年並無顯著差異,因此投資人對於股價的反應僅基於情緒(sentiment),而非出於他們對基本價值的觀察。另一方面,研究樣本公司在 I/B/E/S資料庫中的一致性分析師盈餘預測,發現分析師對此類更名公司的下一季盈餘預測往下修正,但此下修應屬系統性現象。在預測誤差方面,分別探討網路熱潮期與冷卻期的預測誤差後,發現後者為-$0.2650,具有10%顯著水準。故可推論此時期分析師所掌握的資訊較為不足,或是來自世界各地的分析師意見不一致。此外,由於分析師盈餘預測可代表投資人對市場的預期,故在網路冷卻期,投資人對更名公司股價的反應是不理性的。 / This paper investigates long-term versus short-term effects of dotcom corporate name changes from 1997 to 2007. The sample contains a combination of name change events on which firms add dotcom to, or remove dotcom from their names. We attempt to examine whether announcement effects of dotcom name changes last long, or are prevailed by post-announcement negative drift eventually. On the announcement date, we find firms earn significant abnormal returns on the order of 3.14%. However, firms yield negative CARs over the 120- and 360- day window, which are -55.52% and -156.09%, respectively. These results suggest that firms can create shareholder’s wealth by dotcom name changes, but cosmetic effects of their name changes are simply transitory. Due to this finding, we suggest investors who experienced loss on stocks of dotcom addition firms should aware that their loss continues growing as time goes by. Next, the fact that fundamental value of our sample firms does not change significantly indicates that investors are affected by market sentiment, rather than driven by changes of fundamental value. Furthermore, we examine consensus analysts’ EPS forecasts from I/B/E/S database. EPS forecasts are used as proxies of investors’ expectations. We find analysts revise downwards in EPS forecast changes of name change firms. However, there is no significant difference between the sample and the benchmark group, in terms of forecast changes. Accordingly, we conclude that analysts systematically revise their estimates downward. Moreover, forecast errors in the Internet-cold period is $-0.2650 and significant at 10 percent level. We infer that analysts do have sufficient information or consensus. Thus, investors are irrational in response to dotcom name change announcements in the Internet-cold period.

企業公關與行銷公關運作模式之研究-以高科技產業為例 / The Study of Public Relations Model: a Case Study of High-Tech Industry

張凱鈞, Chang, Kai-Chun Unknown Date (has links)
本研究試圖探討環境趨勢之變化、高階主管之經營理念、以及企業本身與公關公司之互動對於高科技企業之公共關係運作的影響,預期達到下列目的:1.從眾多的環境變化因子中,找出影響公關運作的關鍵因子;2.發掘高階主管的經營理念對公共關係運作的影響;3.分別從企業本身與公關公司的角度,探討其在公共關係運作上的互動關係;4.比較獨立進行公關運作的企業與委外公關公司的企業,找出其在公關運作上的異同與優劣處。 在研究設計方面,以公共關係之開放式系統模型為基礎,採取個案訪談法,以本土化程度與產品屬性兩個構面劃分整個高科技產業,並且分別訪談企業主與委外之公關公司,形成一對偶比較關係。 本研究之研究結論發現: 一、在環境趨勢之變化方面,環境趨勢的變化主要來自社會大眾求「知」的意識增加,使得公關「第三者證言」倍受重視;以及網際網路的興起,提高對公關的需求,為公關運作帶來新的傳播媒體與活動,有利於分眾與公關績效的評估,並增加雙向溝通的機會。 二、在高階主管之經營理念方面,當組織的整合程度愈高、人員授權程度愈充份、運作彈性愈大時,則愈利於公共關係活動之運作。而高科技產業裡的公關功能傾向於輔助行銷功能,多隸屬於行銷企劃部門。 三、在企業本身與公關公司互動方面,企業是否委外、委外程度、委外家數、以及角色均應由企業本身的需求來決定。企業主須釐清委外公關公司的目的,並提供其所需資源,公關公司亦應透過各種方式增加對客戶產業的認識,而頻繁有效率的溝通有助於瞭解彼此的現況。 四、在公共關係運作流程方面,企業應有一套流程以利規劃執行。首先應以研究調查的方式找出公關問題,據以訂定公關目標,同時應以「分眾」的概念,找出目標公眾,接著是選擇適當的媒體與結合議題的活動,來與目標公眾溝通,最後是進行公關績效的評估。 最後,本研究建議企業進行公關運作時,應明白自己的需求何在,具有全方位的策略思考;建立使公關公司熟悉其產業與企業本身之機制;將內部公眾亦納入考量。同時建議公關公司應增加公關人員在高科技產業之專業程度;主動積極協助企業體建立品牌、保護品牌;公關公司亦應重視本身的形象與社會公共關係。

鼎峙春秋與關公造型之研究

柳珍姬, You , Jinhee Unknown Date (has links)
《鼎峙春秋》是奉乾隆皇帝的命所創造的作品.本劇本,以元明以來流傳的三國演義故事為題材,僅在清代宮廷裡所演出的劇本。 清代極為崇拜關公,而關公到了《鼎峙春秋》呈顯出最完美的形象. 本論文將關公的一生分為七個時段來探討鼎峙春秋中的關公如何被描述, 其中發現本劇作家透過關公的一生突顯出忠義精神和善惡報應思想,以此教導民眾. 本論文雖然不足的地方很多,希望研究關公的學人有所幫助. / 《Ding Zhi Chun Qiu》 was made by the order of Qian Long the Emperor of the Ch'ing dynasty. It’s a play only performed at Court. And it’s about the story in the period of the Three Kingdoms which has been one of the people’s favorite subjects since Yuan-Ming Dynasty.The people of the Ch'ing dynasty were more devoted to worship Gwangong than any other times. Therefore, the Gwangong who is a main character of 《Ding Zhi Chun Qiu》 is described as the most perfect person whose image is handed down from generation after generation.This paper divided the life of GwanGong into 7 periods based on the important historical trace, and watched how GwanGong’s story was described in《Ding Zhi Chun Qiu》. I was able to find out that the writer had intention to enlighten the people by highlighting a loyalty spirit and right and wrong retribution thoughts through Gwangong in the process. Although this paper has some insufficient points, but I hope this paper would be helpful to those who study Gwangong.
