台灣企業環境揭露程度之研究-應用利害關係人理論

梁亞晴 Unknown Date (has links)
本研究應用Ullmann之利害關係人理論之概念性架構,探討民國92年營收前200之上市公司其年報中有關環境資訊揭露程度。其中利害關係人之影響力以股權集中程度、負債比率、是否在五年內(88-92年)違反環保法規而被處罰、是否為環境敏感性產業來衡量;企業策略態度積極與否以是否有環保專責之部門、處室、委員會來衡量;經濟績效則以資產報酬率來衡量。 研究結果顯示:若應變數為環境揭露程度,則與負債比率(質的方面)、是否在五年內曾違反環保法規而受處罰(質與量方面)、是否為環境敏感性產業(量的方面)、是否設置環保專責之部門、處室、委員會(量的方面)有顯著相關。若應變數為自願性環境揭露程度,則與負債比率(質與量方面)、是否在五年內曾違反環保法規而受處罰(質的方面)有顯著相關。

影響美妝部落格可信度因素探析 / Analysis of factors affecting cosmetic blog credibility

葉凱凌 Unknown Date (has links)
根據經濟部統計,在全球經濟不景氣的情況下,彩妝業在2009與2008年同期相比,仍成長了2.72%,以金額來說,台灣彩妝一年有新台幣720多億元市場,而保養品的市場量則一直維持在美妝品市場40%以上比例,兩者合計之金額足見美妝市場之大。因此對於行銷人員來說,瞭解現代女性選擇美妝產品的方式成為一個重要的課題。 本研究認為,若能瞭解網友信任美妝部落格、部落客的原因,就可取得部落格行銷之先機。本研究發現20-29歲女性在制訂美妝產品購買決策時,除了價格因素外,最重要的因素來自於網友評價。美妝部落格部落客成為美妝領域的「意見領袖」,將影響力由虛擬網路世界深入實體世界。我們將影響部落格可信度因素分為:(1)使用時間、(2)使用動機:資訊搜索、人際互動與娛樂消遣、(3)部落格特性:更新快速、自主控制、互動性、多媒體與分眾化、(4)自我揭露、(5)商業意圖揭露等五大要素。結果發現「資訊蒐集」、「人際互動」、「多媒體」、「主題性」與「自我揭露」等五個變項對可信度有正向影響;而「內容詳盡」與「商業意圖揭露負面感知」對可信度影響為負向。 本研究建議在部落格行銷上,應改進過去多用「量產」的口碑行銷方式贏得市面上的曝光量與正面評價,以提升文章深度。多媒體方面可以提升圖文的質感,主題性上可以形塑部落客在美妝領域的專業角色,並利用自我揭露的方式拉近與網友的距離等方式提高可信度。另外要注意內容過於詳盡易帶給網友不信任的負面觀感,而商業意圖不僅是政府開始注意的議題,也是美妝部落格可信度的殺手。 / According to a Ministry of Economic Affair’s study, cosmetic industry in Taiwan is continuously growing under the global economic recession in recent years. The makeup product market is greater than NT 720 billion a year in Taiwan, in which the proportion of the skin care product market in cosmetic industry remains 40%., which may show the potential of this industry. Therefore, it is important for marketers to understand the behavior of consumers in this industry, especially women’s, accounting for most of the share. Women between 20 and 29 will consider other users’ evaluation of products when they have to make decisions on purchasing cosmetic products. Therefore, it is natural to infer that cosmetic blogs and bloggers will become “opinion leaders” in cosmetic areas, and they may exert their influence on consumers’ consumption. If we know why and how users trust in cosmetic blogs and bloggers, we may help the cosmetics marketing in blogosphere. . Factors affecting blog credibility were divided into five dimensions: (1) time, (2) motivation: information exchange, personal relationship and social recreation, (3) blog feature: quick update, independent control, interactive, multimedia and fragmentation, (4) self-disclosure, (5) business intention disclosure. We found that “information exchange”, “personal relationship”, “multimedia”, “fragmentation” and “self-disclosure” have positive effects on credibility. On the contrary, content of blog feature—“detailed content” and “disclosure of intention to sell” have negative effects. Consequently, this study suggests that from a multimedia perspective, bloggers should improve quality of posts, and upgrade blogger’s professional images. Furthermore, using self-disclosure strategies may improve relationships between bloggers and visitors. Last but not least, detailed content easily brings negative impression, and intentions to sell in blogs were not only monitored by government but viewed as defect of credibility by visitors.

企業以XBRL格式申報財務資訊與經營績效之關聯性研究 / An exploratory study in the relationship between XBRL voluntary filing and firm performance

王祥翊, Wang, Hsiang Yi Unknown Date (has links)
本研究以中國大陸2003年所推動之XBRL自願申報計畫為例,探討率先以XBRL格式申報財務資訊之企業,相較於未率先申報之企業,其經營績效之表現是否較佳?並進一步檢視企業率先申報XBRL之行為與各經營績效層面之關聯性。研究樣本為2000年至2009年於上海證券交易所上市之90家公司,分為兩個群組:一組為參與自願申報計畫之公司共45家,另一組為未參與申報計畫之對照組。在經營績效之衡量部分,本研究依據國內外之文獻探討,將經營績效區分為五個衡量層面:長期償債能力、流動性、獲利能力、經營效率與成長力,並分別以負債比率、流動比率、純益率、股東權益報酬率、總資產週轉率與營收成長率等財務比率做為各層面之衡量指標。 本研究之實證結果顯示,負債比率、流動比率、純益率、股東權益報酬率與總資產週轉率皆呈現顯著相關,證明率先以XBRL格式申報財務資訊之企業群組,在長期償債能力、流動性、獲利能力與經營效率方面之表現皆優於對照組。期望此研究結果能提供資本市場一有用訊息,做為投資人形成投資決策時之參考。 / In 2003, Shanghai Stock Exchange of China promoted a program encouraging companies to voluntarily file financial information using XBRL format. This paper examines whether these early and voluntary filers of financial information in XBRL format demonstrate superior operating performance relative to their non-adopting peers. Samples of this study include 90 listed companies of Shanghai Stock Exchange from 2000 to 2009. Half of them are voluntary filers and the others are the non-adopting peers. The measure of operating performance is divided into five levels: long-term solvency, liquidity, profitability, operating efficiency and growth capacity. Debt ratio, current ratio, net profit margin, return on equity, total assets turnover and sales growth rate are used as the indicators of these measurement levels, respectively. The empirical results of this study show that debt ratio, current ratio, net profit margin, return on equity and total assets turnover are significant, which mean that early and voluntary filers of financial information in XBRL format have superior performance in long-term solvency, liquidity, profitability and operating efficiency. These findings should provide a useful message to the capital market, as investors concern when forming investment decisions.

年報環境揭露與合理性理論-以上市公司為例

王佩如, Wang, Pei-Ju Unknown Date (has links)
合理性理論認為,公司實際的環境績效必須與攸關公眾的期望一致,否則便出現合理性威脅。有合理性威脅的公司,必須向握有公司存續經營准駁權的攸關公眾揭露環境資訊,以合理化其永續經營的權利。為了探究管理當局公開環境揭露的誘因,本研究即根據合理性理論,以我國上市公司中合理性出現威脅的公司為對象,針對該等公司的年報環境揭露程度進行研究,探討攸關公眾之期望與公司年報環境揭露程度間的關係。 本研究之樣本係為60家過去環境績效表現不佳的上市公司,研究期間為民國89年,同時採用數量評估和品質評估兩種評分方式,在對資料之分配進行常態性檢定後,以Spearman等級相關和Mann-Whitney U test進行檢定。 實證結果顯示:(一)在敘述性統計方面,各公司均以「公開發行公司年報應行記載事項準則」所規定的應行記載事項為揭露架構,且多以表格或分點、逐項的方式進行說明,揭露項目雖然一致但揭露內容卻有各自表述的情形。若將數量和品質評估進行比較,染整業及染顏料業之揭露係以宣揚和美化性質的陳述為多,較少論及具體的環保措施,而石化業、化工業和鋼鐵業所揭露資訊的質和量則均高。(二)在假說檢定方面,年報環境揭露程度與平面媒體報導程度、公司規模、所有權結構成顯著正相關。食品、飼料及肥料業可能因為污染問題以及環保訴求略異於其他產業,故年報環境揭露程度顯著異於他業;石化業和化工業則可能因為長年積累的污染問題,使得攸關公眾關切甚殷,故受到合理性威脅的影響較大,其年報環境揭露程度亦顯著異於其他產業。綜合本研究的實證結果,以揭露品質進行的測試多為顯著正相關,較能支持合理性理論的推論,可見國內管理當局認為,當公司實際的環境績效不符攸關公眾之預期,在年報中採取較高程度的環境揭露品質能有助化解合理性威脅,以爭取公司之永續經營權利。 / Legitimacy itself has been defined by Lindblom(1994)as a condition or status which exists when an entity,s value system is congruent with the value system of the larger social system of which the entity is a part. When a disparity, actual or optional, exists between the two value systems, there is a threat to the entity,s legitimacy. Based on the social contract concepts described above, legitimacy theory posits that environmental disclosures(EDs) are made as reactions to disparities, which threaten the sustaining rights of corporations, between relevant publics, expectations and actual performance. In other words, corporations legitimize its existence through making EDs. This study,s objective was to investigate management,s motivations of publicizing EDs voluntarily based on the legitimacy theory. We sampled 60 listed companies which had unsatisfactory past environmental performance. We studied the relationship between their annual reports, ED levels and relevant publics, expectations. After coding these companies, EDs on their 2000 annual reports by using both quantity assessment and quality assessment, we tested hypotheses with Spearman rank-order correlation and Mann-Whitney U test. The results were summarized below. First, based on descriptive statistics, we found most companies, EDs were in compliance with the required disclosure items regulated by law. However, every company had its own interpretation of what each requirement really meant. Regarding the results of two methods of enumeration, the Dyeing industry,s quantitative disclosure levels were high but its qualitative disclosure levels were lower. Petroleum and chemical industries, disclosure levels were very high in terms of both methods. Second, hypothesis testing showed that annual reports, ED levels were positively correlated with the level of print media coverage, firm size, and ownership structure. In addition to food, feed and fertilizers industries, petroleum and chemical industries, ED levels were also significantly different from other industries. Additionally, the qualitative disclosure evidence presented more persuasive results than the quantitative one in our findings. The hypothesis that corporations facing more print media coverage on their environmental performance would legitimize their sustaining rights by making better quality environmental disclosures was supported.

公司資訊揭露與價值攸關性之研究

林冠宏 Unknown Date (has links)
本文利用Ohlson (1995)及Barth (1998)所提出之評價模型,研究91年度我國資訊電子業上市公司,會計資訊揭露之價值攸關性。根據Ohlson (1995)及Barth (1998)之模型,檢測會計資訊價值攸關性之結果顯示,超額盈餘、帳面價值及稅後淨利對於我國之資訊電子業上市公司之股價及市值有顯著之解釋能力。若以「資訊揭露程度」為Ohlson 及Barth評價模型之「其他攸關變數」進行觀察,則資訊揭露程度具有價值攸關性。若進一步將「資訊揭露程度」分成「財務及營運」、「董事會及股權結構」及「公司網站」三細項後,兩種不同之評價模型皆顯示,「財務及營運」之資訊揭露程度與股價及市值間具有顯著之正向關係。「董事會及股權結構」及「公司網站」之資訊揭露程度則會因實證模型之不同,而有不同之結論,在Ohlson 模型中並未獲得支持,但在Barth模型則獲得支持。 / Based on the models established by Ohlson (1995) and Barth (1998), this study examines the value relevance of information disclosure in addition to that of accounting numbers. The sample consists of electron companies listed in 2002. The result indicates that abcdrmal earnings, book value and net income have significant explanatory power about stock price and market value. The ‘information disclosure level’ is also value relevant for both models as ‘other relevant variable’. By dividing the ‘information disclosure level’ into three parts: financial and operating, board and ownership structure, and company websites, we find that ‘financial and operating’ information disclosure level is significantly associated with stock price and market value. The ‘board and ownership structure’ and ‘company websites’ information disclosure level are significant in Barth model, but not in Ohlson model.

年報揭露程度與分析師盈餘預測關係之研究

張窈菱 Unknown Date (has links)
本文旨在檢視股東會年報之資訊揭露是否具有預測價值,分別以年報資訊數量及品質二者與分析師盈餘預測誤差及分歧程度之關係探討之。研究結果顯示,年報揭露之資訊數量與資訊品質愈高,分析師盈餘預測誤差愈低,足見我國年報內容有助於提升分析師預測準確度。就年報揭露程度與分析師盈餘預測分歧程度之關聯性而言,本研究發現,年報資訊揭露數量愈多,分析師預測分歧性愈低;然本研究並未能證實,年報資訊揭露品質與分析師預測分歧性具有顯著的反向關係。換言之,資訊數量與預測分歧性具有較強的負向關聯性,而資訊品質則否。前述研究結果顯示,公司增加年報揭露項目,有助於提升各分析師對未來盈餘預測的共識,然經考量揭露內容的品質之後,其對預測分歧性的影響則較不明顯。推論原因,可能係年報揭露內容不足,使得分析師進行預測時尚須蒐集額外資訊以為彌補,以致降低年報揭露對預測分歧性的影響。

公司自願揭露財務預測影響因素之研究

陳雅蘭, Chen,Ya Lan Unknown Date (has links)
強制性財務預測揭露制度已實施十多年,惟財務預測品質不佳、管理當局刻意操縱財務預測以影響股價等問題遲遲無法解決,致金管會乃決定自2005起廢止舊制,改採自願性財務預測揭露制度。本次改革除符合國際做法之外,並期望能達到降低公司財務預測成本、提高預測準確度,以及健全預測資訊公開之環境。 2005年為實施自願性財務預測揭露制度之第一個年度,當年上市(櫃)公司中,只有約6%的公司自願公開其財務預測。本研究認為,對投資人而言,財務預測既為有用資訊,為何願意公開財務預測的公司卻如此少呢?故本研究欲辨認左右公司是否公開財務預測行為之因素。 本研究設立七項與管理當局自願性揭露財務預測有關之決定因素─內部人持股比率、資本結構、資金需求、經營績效、盈餘波動性、權益資金成本,以及外資持股率,並以公司規模、產業、負債對權益比率為控制變數。研究樣本為2005年之上市(櫃)公司,將其分成兩組,ㄧ組為當年度自願揭露財務預測之公司,另ㄧ組則為當年度未曾揭露財務預測之公司,運用logit進行迴歸分析。 實證分析結果顯示,揭露與不揭露財務預測公司之主要不同特質,在於:公司過去經營績效之好壞及外資對公司之持股比率。過去經營績效較佳之公司,其主動揭露財務預測資訊給外界之機率較高;外資持股比率越高之公司,其主動揭露財務預測給外界之機率較高。 / This study examines the factors that affect managers to disclosure financial forecasts. Seven potential factors were compared for a sample of firms that reported forecasts and another sample of firms that did not release this information. The seven factors are: (1) the proportion of inside ownership, (2) capital structure, (3) the demand for external finance, (4) the business performance, (5) earnings volatility, (6) the cost of equity capital, (7) the proportion of foreign ownership. There are three control variables, including size, industry and the ratio of debt to equity. The findings report that the better the past business performance is, the more the probability that the manager will voluntarily disclose financial forecast is. The findings also report that the higher the proportion of foreign ownership is, the more willing the manager is to voluntarily disclose financial forecast.

非營利組織資訊揭露之影響因素

陳玥君 Unknown Date (has links)
本研究以2005年版《台灣300家主要基金會名錄》上所列之財團法人基金會為研究對象,針對基金會網站資訊揭露的情況進行分析,檢視影響非營利組織資訊揭露程度之組織特性因素。其次,再從組織特性及資訊揭露程度這兩個構面,分析影響捐款收入之因素為何。 研究結果顯示,影響資訊揭露最重要的因素為組織規模、員工人數及所在地。另一方面,影響捐款收入最重要的因素則為員工人數、設立年數及所在地。至於資訊揭露程度,雖然實證結果與預期方向相符,皆是正向的,但是結果並不顯著,表示資訊揭露的程度可能會影響組織所獲得的捐款收入,但並不是最主要的影響因素。

自願性揭露下管理當局盈餘預測準確度決定因素之研究 / Determinants of Accuracy of Discretionary Management Forecasts of Earnings

張希恭, Chang, Peter Unknown Date (has links)
本研究係探討在自願性揭露的情況下,公司盈餘預測準確度會受那些因素的影響?對國內外相關文獻及我國股市資訊環境進行探討後,提出預測期間長短、公司規模大小、盈餘變異性、市場風險、行業別、上市期間長短、自有資本比、綜合槓桿效果、揭露次數多寡、公告媒體別、揭露後累積異常報酬、上市類別、高估低估、預測階段以及年度別等可能影響準確度之因素,利用迴歸分析,以橫斷面(cross-sectional design)之設計方法,來探討各自變數與因變數(盈餘預測準確度)間之關係。   依理論判斷所制定之選樣標準,本研究以117家上市公司對於民國78年度至83年度之盈餘預測資料,共941個觀察值為研究樣本。經嚴格理論建立與統計分析后,本研究得出以下的結論:   一、預測期間愈短、管理當局盈餘預測準確度愈高。   二、公司規模愈大,管理當局盈餘預測準確度愈高。   三、市場風險愈低,管理當局盈餘預準確度愈高。   四、行業別與預測準確度具有關係。   五、自有資本比愈高,管理當局盈餘預測準確度愈高。   六、揭露次數愈多與管理當局盈餘預測準確度具有關係。   七、媒體別與預測準確度具有關係。   八、上市第一類股,預測準確度較高。   九、預測階段與預測準確度具有關係。

國內銀行財務揭露資訊內涵之實證研究 / The Information Content of Financial Disclosures in Bank

劉桂妙, Liu, Kuei-Miao Unknown Date (has links)
本研究主要探討銀行在財務報表上的財務揭露與財務報表外的補充性揭露,如何影響股票市場價值的變化?由於銀行本身主要業務為放款,主要資產來自短中長期放款,這類資產所存在的違約風險以及因利率變動之價值減損風險較其他產業來的高,包含逾放款的產生以及放款期間結構的改變等因素,因此欲透過財務資訊的揭露,探討影響銀行股票市場價值變化的因素。本研究首先分析備抵呆帳、逾放款、放款期間結構與股票市場價值間之關係,其次再加入放款成長、買賣票券損益前純益、淨值成長率三變數,連同原先模式中之備抵呆帳、逾放款、放款期間結構,測試其對於股票市場價值之影響。另外透過虛擬變數的設立,重新測試模式。除以上模式採總額水準做測試外,另採增量水準觀念,測試兩期間備抵未帳、逾放款、放款期間結構、買賣票券損益前純益之變化對於股票市場價值變化之影響。   本研究係由探討國內外相關文獻,參考國內環境,加以延伸,蒐集民國七十八年至八十二年的資料,以分年及POOLING方式,另外亦透過FIXED EFFECTS MODEL做迴歸分析,探討財務資訊之資訊內涵。   經過實證結果,獲致以下結論:   1. 分年測試的結果,由於樣本數太少,結果不理想。   2. 備抵呆帳此項揭露在所有模式均具資訊內涵。   3. 買賣票券損益前純益亦具資訊內涵。   4. 逾放款、放款期間結構變數由於國內資料受限,未顧及時效性的因素及人為武斷定義變數的選取,並未在所有模式中得到與預期一致的結果。
