本論文研究目的，在針對國內上市公司，建立一套股利發放模式，找出影響現金股利與股票股利發放之重要因素，並根據其因素之一：營業利益成長率，探討其與現金股利之關係，以作為分類之依據，來測試現金股利顧客效果，但若關係不顯著，不適合作為分類之標準，則將深入探討產業間發放現金股利之屬性，決定出分類標準，對現金股利顧客效果進行測試。 　　根據上述研究目的，建立出三大假說，所抽樣之樣本為在台灣證券交易所上市之股票，其研究期間自民國七十九年至八十三年，經篩選後有效樣本共103家。在研究方法上，對於影響股利發放模式之重要因素淬取，採用複迴歸模式中之順向選擇法，利用相關分析探討成長機會與現金股利之關係，而關於產業間發放現金股利之現象，採用無母數變異數分析加以檢定，至於現金股利顧客效果之測試，則以Elton&Cuber（1977）之模式為主。 　　實證結果發現：影響股利發放模式之兩大重要因素為股利平穩性及每股盈餘；而成長機會與現金股利之關係為負相關，但並不顯著；產業間發放現金股利有明顯不同，利用Duncan多重分類法可分為三群；在現金股利顧客效果實證結果為在民國七十九年停徵證券交易利得稅，本研究從高現金股利發放群與中現金股利發放群進行測試，所得之結論為國內上市公司並不存在現金股利顧客效果。 　　在建議方面：建議上市公司建立一套健全股利發放政策及對於股利政策因素之考慮，應從多個構面決定，以求得公司最佳股利政策；對於投資者，建議投資時所考慮之構面應增加；而證券交易所得稅停徵所引起之爭議，建議政府機關作更審慎之評估。

本文以2000~2009台灣地區不含金融證券業之上市公司為樣本，資料來源為台灣經濟新報社資料庫(Taiwan Economic Journal)，研究主題為探討多角化與股利發放政策之關聯性，同時也檢測多角化程度愈高而經營績效較差或盈餘品質較差的企業與股利發放政策之關係，實證研究的結果顯示，多角化程度會影響股利發放政策，而多角化與股利發放政策呈現顯著負相關，企業多角化程度愈高，股利支付率較低、較不會發放股利及較不會增加發放股利，而這些現象主要是集中在經營績效較差或盈餘品質較差的企業。 / Based on a sample of firms listed in Taiwan during 2000-2009, this study investigates the relationship between firm diversification and dividend policy and the extent to which firm performance and earnings quality affect diversified companies in making dividend policy decisions. The empirical results show that firms with greater diversification are less likely to pay dividends, pay lower dividend yields, and are less likely to increase dividends. I also find that such evidence is more pronounced among poor financial performance and lower earnings quality firms.

本研究以清朝八旗軍之薪餉制度規範作為研究目標，尤分析乾隆41年頒訂之《欽定戶部則例》卷一百二「放餉定期」至卷一百四「駐防馬乾折價」有關八旗兵餉規範。而當代臺灣軍事制度歷經對日抗戰、國共內戰等階段，迄今或多或少較當時清朝政府受到更多西方知識思維與管理制度之影響。 第二章探討清代兵餉制度發展沿革及《欽定戶部則例》相關規定，介紹八旗軍薪餉發放、申領等作業程序並加以研析。《欽定戶部則例》共12門，卷101至卷107屬於兵餉門，因清朝八旗軍屬常駐性質，各駐防區兵力需求及勤務分量有所差異，故於卷101針對建立兵餉發放制度緣由及重要性加以說明。 第三章就臺灣現代國軍人員薪餉制度發展沿革及待遇規定分別說明，並針對薪餉發放作業執行要點及程序進行重點分析及介紹。現代國軍人員薪資待遇發放主要以《軍人待遇條例》為基準，輔以《國軍副食實物補助費支給要點》及《國軍財務單位發放薪餉作業要點》等規定辦理相關作業，使整體運作趨於法制化。 第四章透過清代與臺灣現代薪餉制度法源依據差異性之探討，逐步進入薪餉發放作業規範、薪資架構制度及法令、人員職務異動及補充兵源及薪餉追繳制度等細部規範加以比較；同時也於部分比較上輔以清代官員呈送奏書之文獻，加以確認該規範之執行性，期使本章節之內容更趨完整。 末章總結兩個時代服役軍事人員薪餉法令及執行制度均有類似，並顯示法制延續性應是清代末期受資產階級法律體系和原則之衝擊；另因國內學術界對於《欽定戶部則例》兵餉門之探討研究尚於起步階段，研究過程中仍可發現考核獎賞或撫卹等亦有其相似處，建議期使能成為各界未來之研究議題。

本研究係以裁量性應計數字及其組成成分衡量盈餘管理，以審計人員產業別市場佔有率與產業別客戶集中度之綜合衡量捕捉審計品質，探討不同樣本公司之盈餘管理特性，以及審計品質對不同盈餘管理特性之影響。管理者對應計項目的認列通常有某種裁量權，此裁量權可用以顯露私有資訊而增進盈餘的價值攸關性，或可投機性地管理盈餘而減低盈餘為公司績效衡量的可靠性。所以探究盈餘管理行為是增加財務報告資訊性(information)或雜訊(noise)即非常重要。研究內容依盈餘管理特性區分為投機性盈餘管理與訊息發放性盈餘管理二大部分。每一研究內容則是先辨認盈餘管理本質，其次探討審計品質對盈餘管理之影響。在研究設計上，為避免實證代理變數之衡量誤差重大影響結果，乃採用實驗組公司與控制組配對公司相比較，以凸顯出前者之盈餘管理型態。 　　研究結果顯示，門檻公司從事盈餘管理以達前期盈餘門檻，且此盈餘管理不具未來現金流量持續性之涵義，係符合「隱藏當期不利績效、遞延本期不尋常盈餘至未來年度」以減低會計盈餘數字波動性之特性。就自願性盈餘預測此一資訊揭露工具而言，在盈餘預測偏屬樂觀之傾向下，仍有管理者自願揭露壞消息預期，即可知管理者之誠意，不失為一可資信賴之訊號。但自願預測盈餘增加，則不必然具有高公信力。甚至在管理者降低盈餘差距之動機下，易引起管理者操縱盈餘。此為財務報表使用者所需注意。就持股變動此一資訊揭露工具而言，在我國家族企業居多之情形下，增加持股並未代表任何特定之涵義。反而是減少持股所透露之訊息，值得投資人注意，尤須慎防其盈餘操縱行為。 　　面對增加所得之裁量性應計數字，審計品質有效阻止投機性盈餘管理。面對顯露私有資訊之盈餘管理，審計品質能夠協助管理者選擇最能彰顯未來現金流量預期之會計方法，以增強裁量性應計數字與未來現金流量變動之關聯性。在高審計品質所賦予之資訊公信力下，盈餘資訊在投資人之決策過程中有一定之重要性，故投資人發現裁量性應計數字增加（減低）盈餘價值攸關性，因而增加（減低）盈餘評價係數。然而對低審計品質所查核的財務報表，較低的資訊公信力，使盈餘未在投資人評價過程中扮演重要角色，因而盈餘管理特性亦不受投資人重視。 / This research examined characteristics of earnings management and effects of audit quality therein. Specifically, the magnitude of earnings management was proxied by the discretionary accruals, which are estimated using a cross-sectional version of the Jones model. Different from prior research, the audit quality was captured by a combined measure of the auditor's market share and client concentration. The market share measured the auditor's competence (industry specialty) and the client concentration measured the auditor's independence. Managers usually exercised discretion to recognize accruals. They could either signal private information to enhance earnings' value relevance, or opportunistically manage earnings to reduce the reliability of earnings as the performance measure of the firm. As a result, it was important to examine earnings management and to identify whether it would increase the informativeness or noise of financial reports. This study was organized according to the characteristics of earnings management: opportunistic earnings management and signaling earnings management. For both parts, the nature of earnings management was identified first, and then the effects of audit quality therein examined. To reduce the impact of measurement errors of proxy variables, the treatment group and controlled group were compared and contrasted to make earnings management pattern of the treatment group more evident. 　　The results showed that threshold firms managed earnings to sustain last year's earnings level. Discretionary accruals of the threshold firms were not significantly associated with future cash flow changes. Those discretionary accruals were used to hide the current unfavorable performance, or to defer current unusual earnings to the future, so that managers could reduce the volatility of accounting earnings. As a means of information disclosure, voluntary earnings forecasts tended to be optimistic, but we still could observe some voluntary forecasts which decreased earnings. In those situations, we might conclude that managers tried to convey credible signals. However, it was not necessarily credible in the case of voluntary forecasting which increased earnings. Managers would manipulate earnings to reduce the difference between forecasted earnings and reported earnings. In respect of the information signal of changes in directors' share holding percentages, it signaled nothing when directors increased holding percentages because most companies were family businesses in Taiwan. Nonetheless, investors should look out the possibility of earnings manipulation when directors decreased their holding percentages. 　　Audit quality could effectively deter opportunistic earnings management but not the income-decreasing discretionary accruals. Based on information signaling perspective of earnings management, auditors with higher audit quality tended to assist managers to choose accounting methods that might signal cash flow expectations. Stronger associations between discretionary accruals and future cash flows were observed for firms audited by higher quality auditors. Because higher audit quality might increase information credibility, earnings would play a more important role in the decision process of investors. When discretionary accruals increased (decreased) earnings' value relevance, earnings association coefficients would be increased (decreased). However, for the financial reports audited by lower quality auditors, earnings did not play an important role in the valuation process because of lower information credibility. Therefore, empirical results showed that investors of firms audited by lower quality auditors did not make decisions according to different characteristics of earnings management.

本論文探討兩稅合一制所增設的兩個機制，即稅額扣抵比率及加徵保留盈餘稅對上市公司股利發放、資本結構以及公司租稅規劃的影響。首先以數學模式推導出兩稅合一制下這兩個機制與股利發放率及負債權益比率之間的關係，再據以建立研究假說，而後進行兩步驟多變量程序之實證測試。研究所獲致的結果包括： 　　一、兩稅合一制實施後，上市公司稅額扣抵比率與總（盈餘）股利發放率呈正相關，且上市公司稅額扣抵比率愈高者，其總（盈餘）股利發放率、現金股利發放率及盈餘配股發放率皆較兩稅合一制實施前高。由於公積配股並不受兩稅合一制實施的影響，故本文也發現兩稅合一制實施前後公積配股率並無顯著差異。整體而言，兩稅合一制實施後，總（盈餘）股利發放率、盈餘配股發放率及公積配股率較實施前減少，而現金股利發放率較實施前增加。進一步的分析顯示現金股利發放率的增加係受到健全股利政策的推行影響，而盈餘配股發放率的減少可能是受到股票股利緩課取消的影響。 　　二、兩稅合一制實施後，符合促進產業升級條例第八條及第九條規定之投資方案，選擇股東投資抵減之公司並無顯著多於選擇五年免稅之公司，可能原因為選擇五年免稅有利於公司現金流量及每股盈餘的金額。此一結果雖與預期方向相反，但也顯示政府原先擔心公司會選擇股東投資抵減而造成鉅額稅收流失的疑慮並未獲得實證支持。但從兩稅合一實施後公司股權結構的變動分析顯示，公司法人持股比率較實施前增加，而僑外投資持股率較實施前減少，支持公司在不同股東身分稅負差距的考量下，會有股權結構移轉之租稅規劃，以降低股東所負擔的稅負。 　　三、兩稅合一制實施後，上市公司稅額扣抵比率愈高者，股東所享扣抵權愈多，則舉債租稅利益愈少，因而總負債權益比率將降低；而上市公司保留盈餘比率愈高者，所課徵的保留盈餘稅愈高，舉債利息的租稅利益反而增加，會造成總負債權益比率增加。本文的實證結果也顯示，兩稅合一制實施後，上市公司稅額扣抵比率愈高者，其總負債權益比率較實施前低；而上市公司保留盈餘比率愈高者，其總負債權益比率較實施前高。 　　綜合本論文實證結果顯示，兩稅合一制實施後，稅額扣抵比率的機制確實其有消除股利所得重複課稅的效益，進而提高公司股利發放的意願，並且有助於公司資本結構的改善。但是，政府對於未分配盈餘加徵 10％營利事業所得稅的規定卻不利於公司資本的累積，反而提高舉債的租稅誘因，也可能抵銷稅額扣抵比率降低舉債的效果，值得政府深入檢討對公司未分配盈餘課稅的不利影響。 / Enacted in 1998, the Integrated Income Tax System has two important features, i.e., the imputation tax credit to shareholders and the 10% surtax levied on undistributed earnings. Using two-step multivariate regression, this study exmines the impacts of these two features on corporations' dividend payout, tax planning, and capital structure. The findings of this study are as follows : 　　1. After implementation of the Integrated Income Tax System, the imputation tax credit ratio is positively related with total dividends payout ratios. Companies with higher imputation tax credit ratios tend to pay out more cash dividends and earnings stock dividends, ceteris paribus. However, there appears no significant relation between the imputation tax credit ratio and capital stock dividends. On average, after implementation of the Integrated Income Tax System, stock dividend payout ratios, including earning stock dividends and capital stock dividends, are decreased, but cash dividend payout ratios are increased. The increase in cash dividend payout may be affected by the balance dividend policy by the SEC, which require corporations to pay out greater proportions in cash dividends. The decrease in earning stock dividends may be due to the cancellation of the deferral of tax on stock dividends. 　　2. After implementation of the Integrated Income Tax System, inconsistent with the expectation, companies still prefer the five-year tax exemption to the investment tax credits. The results suggest that companies' choices are affected more by such factors as corporate cashflows and earnings per shares. However, after implementation of the Integrated Income Tax System, there is a significant change in stockholder structures, with the ratios of corporation stockholders being increased while the ratios of oversea stockholders being decreased. The opportunity of tax arbitrage will have a significant impact on corporations' stockholder structures. 　　3. After implementation of the Integrated Income Tax System, for companies with higher imputation tax credit ratios, their stockholders will have greater tax benefits, and, hence, the tax benefit for companies to use debt financing is decreased. Conversely, companies with higher ratios of retained earnings will bear more tax burdens on the 10% surtax levied on undistributed earnings; therefore, the tax benefit of debt financing is increased. The empirical results support that, ceteris paribus, companies with higher imputation tax credit ratios tend to have lower debt-to-equity ratios, while companies with higher ratios of retained earnings tend to have greater debt-to-equity ratios. 　　In summary, after implementation of the Integrated Income Tax System, the imputation tax credits reduce the double taxation on stockholders' dividend income and, hence, improve corporations' capital structure. However, the 10% surtax on undistributed earnings may result in opposite effect on corporations' capital structure. The findings of this study have important implications for the government to take into account the potential adverse impacts resulted from taxes levied on corporations' retained earnings.
