上市公司從事海外直接投資對股東財富影響之研究 / A Study of The Influence on Stockholder's Wealth of Publicly Published Corporations Doing Foreign Direct Investment

邱足恩, Chiu, Tsu En Unknown Date (has links)
國內上市公司在面臨台幣升值、勞工成本上揚、環保意識抬頭、及勞資糾紛不斷等種種不利因素,為求生存與發展,紛紛移往海外投資。而隨著國際經濟環境的變化,國際投資活動在未來全球經濟舞臺上所扮演的角色與功能將日益重要,台灣企業為了增加國際競爭力,赴外投資乃時勢所趨。關於企業海外投資對股東財富的影響,過去國內的研究均只著重於報酬的衡量,並未曾對風險面加以探討。此研究則進一步探討海外投資事件前後的風險變化情形,以考慮風險變化之研究方法進行實證研究,並比較不同投資型態及投資地區對股東財富的影響是否不同。   實證結果顯示,海外投資事件前後,因受整體股市影響,投資人所面臨的投資環境已經改變,承受的風險程度也會因此不同。就個別股票而言,大多數樣本事件前後的股票報酬變異也確實產生改變。所以傳統事件研究法假定事件期間的風險與估計期一樣,顯然並不適宜。   本研究採用修正後的事件研究法進行檢定,結果發現,上市公司從事海外直接投資的消息對股東財富會有正向但並不顯著的影響效果。不同投資地區對股東財富的影響並無明顯差異,但股市對不同投資型態的反應則有所不同,對企業以獨資方式進行投資的反應優於購併方式。

上市公司赴大陸投資消息宣告對股東財富影響之研究 / The Wealth Effect of Foreign Direct Investment:The Case of R.O. C. Investment in China

羅美煒, Lo,Meei Wuei Unknown Date (has links)
隨著國內投資環境的惡化、大陸實施經濟改革、以及政府大陸政策的開放 ,中國大陸已經成為廠商海外投資的主要地點。國內上市公司赴大陸投資 至今已三年多,投資的家數有不斷增加的現象,對上市公司而言,大陸投 資似乎已經是一個無法避免的趨勢。在國外,有關海外投資對股東財富的 影響已經不少,而國內則因為大陸投資尚在初期階段,所以目前仍無相關 的論文針對大陸投資對股東財富的影響進行研究,很自然的,將造成公司 管理當局、投資者、以及政府有關單位在決策時缺乏這方面的實證研究可 供參考,所以本研究是以這個角度來探討大陸投資對股東財富產生何種影 響,並且分析投資金額、投資型態、進入時機、經營績效、以及海外投資 經驗等五個變數對財富效果的影響。本研究以事件研究法(event study) 進行實證,實證結果發現,無論以平均異常報酬率、累積平均異常報酬率 、或符號檢定法進行統計檢定分析,結果皆顯示上市公司大陸投資的消息 經宣告以後,該公司股東所得到的是負的異常報酬,這表示公司管理當局 在進行大陸投資的決策時,很顯然的,並非站在增加股東財富的立場去考 慮,此結果與國外的研究恰好相反。在上述的五個變數中,經複迴歸分析 發現,投資金額、進入時機、以及海外投資經驗與財富效果有反向的關係 ,而投資型態則沒有很顯著的影響,不過在採用合資方式進入時,投資者 較偏好低的控股比率,最後,在經營績效方面,此變數與財富效果有顯著 的正向關係,此結果並不支持政府的開放原則,也就是從財務管理的角度 來看,經營績效愈好的公司愈適合到大陸投資。

台灣企業購併宣告對股東財富之影響

葉秋美, Ye, Qiu-Mei Unknown Date (has links)
嘗試放棄傳統事件研究法 (event study)的固定系統 ,先針對股價的結構變化點作檢定,找出子區間的分到傳統的方法,根據系統風險改變的時點找出估計期窗口(-5, 5)中 AR、CAR 的變化情形,以測試資本市告之反應,並試圖找出其可能的影響因素。實證結果告對主併公司的股東財富雖然有正面影響(僅1.82﹪) ,但整個宣告窗口的累積效果似乎不大;而跨國購併之間的差異(國際效果),除了購併宣告當日外顯然另外,水平型態的購併事件與產業的技術密集程度之宣告日後才顯現出來,至於支付方式對宣告效果所產國外的實證結果不符,而購併成功與否對主併公司之顯。

公司治理與盈餘的預測及發布對投資人的影響 / The impact of corporate governance and announcement of earnings forecasts on investors

蘇育真 Unknown Date (has links)
本文以事件研究法探討在公司治理程度不同的公司發布盈餘預測時, 不同類型的投資人在事件窗期中所反映的投資行為。首先以獨立董事與監 察人佔董監席次比例、董監事持股比例、大股東持股比例、經理人持股比 例、機構投資人持股比例、盈餘股份比以及董事長是否兼任總經理作為判 別公司治理程度的指標。再以公司發布盈餘預測的時點做區別,分別以當 年度首度預測是否由公司本身發布,與之後調高以及調低預測做為事件日。 實證結果顯示,當公司治理佳者發布盈餘預測時,外資會出現較多的買超 行為且獲得較高的異常報酬,散戶則持相反動作;而公司治理差者發布盈 餘預測時,散戶的買賣超變化量一般而言會較法人大,出現短期進出的情 形較多,且外資在其調高盈餘預測時,也不會馬上進行買進。整體而言, 外資在公司發布盈餘預測時所做出的交易行為,大致上與公司的治理程度 有正向關係,散戶則大多報持短線進出的態度。 / This study examines how different types of investors behave when entities with different corporate governances announce earnings forecasts. Using seven corporate governance indicators to categorize all of the samples and analyzing how the abnormal return, the results suggests foreign institutional investors are gaining more abnormal return by buying more stocks after earnings announcements of the entities with better corporate governance, and would not interact right after earnings announcements of the entities with worse corporate governance, when the individual investors are going the opposite way to the foreign institutional investors.

The Impact of IEA Reports on Oil-Related Markets

陳俊源, Chen, Jiun-Yuan Unknown Date (has links)
國際能源機構(IEA)每個月的石油報告已經變成預測世界石油供給與需求一個很重要的資源。因此,我們蒐集從1990年10月到2005年12月中國際能源機構所發佈的179次宣告,利用事件研究法來衡量國際能源機構對石油相關市場的影響性。 實證結果顯示,國際能源機構的石油報告的確對石油相關市場傳達重要的資訊;而國際能源機構報告的影響效果似乎會隨著國家的不同而有所不同;在當中,石油的生產和消費量多寡、石油的密集度和油價中稅占的比例都扮演重要的角色;此外,在國際能源機構的報告中,關於預測石油需求變化這方面似乎特別被大家所重視。 / This study examines the impact of International Energy Agency's Oil Market Reports on oil-related prices. The IEA reports, published monthly in Paris, have become the primary source of world oil supply and demand forecasts. We collect 179 announcements that released by IEA over the period October 1990 to December 2005. We analyze the effects of these reports on three oil-related markets, IPE Brent Crude futures, oil industry indices and stock prices of oil companies in six countries. Moreover, we separate the effects of IEA’s forecast changes on oil supply from non-OPEC countries and oil demand from North America and China in IEA’s report. The results confirm that IEA’s reports carry important information source for oil-related markets because more than one half of our sample companies have abnormal returns around the announcement date of IEA’s reports, and we explore these prices respond negatively to the release of IEA’s reports. We also find that the actively traded IPE Brent Crude futures contracts are affected by IEA’s reports, particularly for the change of demand in North America. Forecast changes in IEA’s reports regarding supply in non-OPEC countries, demand in North America and China show that most countries are affected by the changes in these reports. The evidences also show that British and Norwegian oil stock markets react more strongly to the change of oil demand in North America and China. Moreover, we find that participants in the oil market put more emphasis on demand changes reported by IEA, especially for China demand. And we provides empirical evidence that these companies are concerned more about the related releases of decreased demand in North America and increased demand in China. Finally, cross-sectional analysis of cumulative abnormal returns suggests that the reaction of American and Norwegian companies to IEA’s announcements is stronger than other countries, and the change of demand in North America and China and the size variable for individual company contribute to the changes of abnormal returns around IEA’s reports.

私募宣告之資訊內涵

陸潤生 Unknown Date (has links)
本研究探討私募宣告事件之資訊內涵,以瞭解私募宣告事件對公司整體價值所造成之影響,進而探討影響私募宣告效果的可能因素,並比較具備投資機會組與不具備投資機會組之累積平均異常報酬。 實證結果發現以股東大會日為宣告日之私募股權宣告具有資訊內涵,而且宣告效果提早反應。影響私募宣告後累積異常報酬之因素包括價格壓力、投資機會、發行價格及資訊不對稱程度。股票流動性高、股價波動程度低、具備投資機會、發行價格高或資訊不對稱程度高時,私募宣告後之累積平均異常報酬會較高。在事件日前,無投資機會組比具備投資機會組有較高之累積平均異常報酬;在事件日之後,具投資機會組比無投資機會組有較高之累積平均異常報酬。 / This study examines the information content of private placement announcement to unveil its impact on firm value, explores the factors affecting the effect of private placement announcement, and compares the market performance of firms with investment opportunities and those without investment opportunities. The results indicate that the information content of private placement announcement exists with early information leakage. Firms with higher stock liquidity, lower stock price variation, more investment opportunity, higher subscribed price or higher degree of information asymmetry will have higher cumulative average abnormal returns after the announcement. The cumulative average abnormal returns of companies without investment opportunity are higher than those with investment opportunity before the announcement date.

經商環境對已開發國家銀行跨國併購新興國家銀行之績效影響 / The affect of the ease of doing business to the developed country mergers the EME

林亮璇, Lin, Liang Hsuan Unknown Date (has links)
隨著新興國家金融管制的鬆綁,國際間銀行業併購的標的已逐漸由美國、歐洲等已開發國家延伸至拉丁美洲、東南亞等新興國家。本論文以事件研究法對2005年到2014年,已開發國家銀行跨國併購新興國家金融產業的併購活動,共49個樣本進行分析,藉由迴歸分析的結果去觀察目標國家的經商環境對於併購績效的影響。 本研究的立論在於,過去文獻表示銀行跨國併購的主要動機之一為追隨客戶,而如今許多銀行的客戶為了降低勞動成本,紛紛前往新興國家設廠,而新興國家相較於已開發國家的其中一個特點為,其經商環境尚未發展健全,不如已開發國家穩定,故目標國的經商環境好壞很可能是影響主併銀行客戶決定是否進入或擴大投資的因素,進而成為影響主併銀行跨國併購的成敗因素之一。 而本論文的結果可分為三個層級。第一層是各別經商環境指標對主併銀行宣告效果的影響;第二層逐漸收斂為企業創立、企業擴建與企業經營三組指標對主併銀行宣告效果的影響;第三層則收斂為綜合性經商環境指標對主併銀行宣告效果的影響。在第一層級中發現:目標國家開辦企業程序的便利簡潔度、取得信貸的流程明確度與能否有效執行合約等排名,在事件窗口(-1,+1)呈現顯著負相關,亦即此三項經商環境指標排名越高(數字越小)對主併銀行的宣告效果有正面影響。在第二層級中則觀察到企業擴建層面的指標對主併銀行宣告效果的解釋力是最大的、其次是企業創立,最後為企業經營。在第三層面中發現收斂後的綜合經商環境指標確實對銀行的宣告效果1%的顯著水準,亦即當主併銀行選擇經商環境較佳的目標國家進行跨國併購時,市場的反應會較為正面。 / Prompted by financial liberalization and the expansion into emerging market economies (EME) by corporate customers, international banks increasingly penetrated EME. This research uses 49 cross-border M&A samples between 2005 and 2014 in which the acquiring banks is in developed countries and the targets is the financial industry of emerging countries. Using event study methods, the study establish whether the business environment of target countries explain returns to shareholders in acquiring banks from cross-border M&A. From the past study, we observe that one of the main motivations for the banks to cross-border M&A is following customers to new markets. Recently, in order to reduce labor costs, the customers of bank have more FDI in emerging countries. However, the feature of emerging countries is that the business environment is not as stable and clear as the developed countries. Therefore, the business environment will affect the customers of banks decide whether to enter or expand investment in EME and further affect the acquiring banks. The results of this research can be divided into three levels. (1) in the individual business environment indicators level, the study find when the target countries are easier starting a business, getting credit or enforcing contracts, the CAR of acquiring banks will significant negative in event window (-1, +1); (2) in the group of business environment indicators level, the study observe the explanatory power of the business expansion group is larger than the group of start-up and operations; (3) the composite business environment indicator have significant negative affect to the CAR of acquiring banks.

專家意見評價結果與品質和主併公司股價關聯性-以台灣上市公司為例 / Appraisal Outcome & Quality In Fairness Opinion For Acquiring Firms

盧作倫, Lu, Tso Lun Unknown Date (has links)
本研究以2002年至2013年台灣主併公司為上市公司的併購案件為樣本,探討專家意見評價結果和品質對主併公司短期股價影響。本研究結果有兩項發現: 1. 於意見書揭露日時,若專家意見書評估價格高於雙方約定交易價格愈多時,即評價溢酬愈大,主併公司會有負向的累積異常報酬率。 2. 於意見書揭露日時,若併購溢酬越大、或是併購溢酬大與評價品質高,主併公司會有負向的累積異常報酬率。 故本研究認為,台灣獨立專家制度相較歐美國家仍不成熟,相關配套措施及規範未規畫周詳,對於獨立專家的獨立性、專業性之確保,以及出具意見時評價方法的選擇標準、意見書應記載事項等規範過少,使得專家意見書於揭露時評價結果易受到市場及投資人懷疑。另外評價品質與主併公司異常報酬的關聯性在少數的樣本下無法表現出顯著性,市場及投資人較傾向以併購溢酬做為交易出價是否過高之依據。 / This study analyses the relation between target firm appraisal outcome and quality disclosed in the fairness opinions and acquiring firm performances by using the samples of Taiwanese listed company in M&A transaction between 2002 and 2013. We find that the stock price reactions to the public disclosure of fairness opinions are negatively related to the difference between target firms valuations contained in the fairness opinion and the merger offer price. In addition, the greater the acquisition premium for or acquisition or high acquisition premium with high appraisal quality would result in negative stock price reactions as well. Under these conditions, this study suggests that Taiwan's independent expert system in Taiwan still appeared to be immature, including that related supplementary measures are not careful planned, the independence of the independent expert, the professionalism of independent expert, and the criteria of valuation methods are not carefully regulated by the government. Therefore, the outcome and the quality of the fairness opinion may not to be trusted by the market and investors. Also, the association between appraisal quality and abnormal unable to be significant could result from the lack of number of samples.

已開發國家食品產業跨國購併宣告效果之研究 / Announcement Effect of Food Industry Cross-Border Mergers and Acquisitions - Evidence from Developed Countries

吳宜頻, Wu, I Pin Unknown Date (has links)
本研究以2002年至2012年已開發國家食品產業跨國購併案為樣本,以事件研究法,比較已開發國家食品產業跨國購併已開發國家及開發中國家企業的購併宣告效果,去看在跨國購併的文獻議題上和實證結果是否相符。並以雀巢集團為收購公司之案例,比較其進軍已開發國家(美國惠氏營養品)及開發中國家(中國徐福記)的策略及收購後營運與財務績效,可否套用於產業研究結果,希望為後續食品產業購併提供研究參考。 本研究有以下三點發現:1.食品產業自已開發國家購併已開發國家對收購公司的股價宣告效果,較購併開發中國家對收購公司的股價宣告效果佳。2.已開發國家之食品產業收購與該產業相關性越高的企業,對其收購公司的股價宣告效果並無重大顯著之影響。3.無法將雀巢集團收購惠氏營養品之個案套用於產業研究結果,收購徐福記之個案則與實證結果相似,無正向顯著的宣告效果。此二個案皆著重搶攻新興國家市場,並以水平整合及策略互補方式,擴大市佔率及強化產品線,近五年之財務狀況,與同業相比有較佳之獲利表現,且繼續經營之價值。 已開發國家食品產業在選擇跨國購併對象時,可以已開發國家企業為主要收購對象,降低文化及地理距離帶來的資訊不對稱問題及取得策略性資產,投資人對其有較佳的預期,在選擇向前垂直整合策略時需留意,因零售通路需較大規模之經營整合,對於該市場需有更深入之了解,才適合投入至通路端。 / This paper treated cross-border Mergers and Acquisitions (M&A) cases of developed countries’ food industry over the period of 2002 to 2012 with event study. We compared the announcement effects of acquired companies following developed or developing countries M&A and to confirm that whether the empirical results are consistent with the literature. We used Nestle S.A. as acquiring company to compare its M&A’s strategies and performance when acquiring Wyeth Nutrition and Hsu Fu Chi. Hope to be the reference for the following food industry M&A research. The major research finding as follows. First, the announcement effects of developed countries’ food industry following developed countries M&A are better than developing countries M&A. Second, the results demonstrated that the announcement effect had no significant difference among different industrial relevance of target companies. Third, the case of Hsu Fu Chi acquisition is similar with the empirical results but Wyeth Nutrition acquisition cannot. Furthermore, both cases were focused on the emerging markets and complementary strategies. Developed countries’ food industry can chooses the developed countries’ firms as target companies to decrease asymmetric information which caused by cultural, economic and geographic distance and to acquire strategic assets. They also should have enough acquaintance of the markets before they invest in the channel.

庫藏股減資和現金減資宣告效果之比較 / Comparison of The Announcement Effect of Stocks Repurchase and Cash Reduction

林雅萍, Lin Ya Ping Unknown Date (has links)
本研究探討國內上市櫃公司庫藏股減資及現金減資宣告效果之比較。研究台灣2006年1月至2010年2月底之間進行庫藏股減資及現金減資的上市櫃公司,分別以事件研究法、多元迴歸分析(Multiple Regression Analysis)及多元名義羅吉特迴歸(Multinomial Logistic Regression)探討庫藏股減資及現金減資兩組樣本之宣告效果及影響宣告效果的因子,並進一步探究影響減資政策選擇的因素。本研究之實證結果發現:1.公司宣告庫藏股減資及現金減資在事件日當天皆具有顯著的正向宣告效果。2.公司宣告庫藏股減資與現金減資之間的累積異常報酬率無著顯著差異。3.以多元迴歸分析探討影響庫藏股減資及現金減資之間累積異常報酬率的因素,結果顯示減資比率顯著地影響累積異常報酬率,其餘本研究選取的公司規模、股價淨值比、負債比率、自由現金流量比率等解釋變數,無法顯著地影響累積異常報酬率。4.以多元名義羅吉特迴歸檢驗不同的解釋變數會造成公司傾向進行庫藏股減資或現金減資的減資政策,結果顯示規模愈大、股價淨值比愈高、自由現金流量比率高、減資比率高的公司,傾向使用現金減資;而負債比率高的公司,傾向使用庫藏股減資。
