近幾年來，隨著資訊科技的快速發展，國內的產業結構產生明顯的變化，重心轉移到資訊電子業上。本研究期望透過研究投資人是否會以不同角度，衡量不同產業間公司股票股利的宣告。另一方面，關於配股率高低是否會具有影響股價異常報酬的現象，國外的文獻如Woolridge(1983)、Baskin(1989)等，認為配股率高低將會產生不同的異常報酬，股利支付較高樣本，當股利支付率越高，股價的異常報酬也會越明顯且具有正面的影響。本研究試圖透過實證分析，瞭解國內的股票市場是否也存在同樣的現象。 本論文採取事件研究法，對新上市公司進行首次股票股利宣告的事件，並分為兩組樣本電子類股與非電子類股，進行實證研究。另外，透過股利支付率的控制，檢驗高股利支付率組會不會比低股利支付率組，產生較大的正異常報酬率。本研究共蒐集了民國80年1月至民國89年6月共9年的時間，台灣證券交易所首次上市公司，無償配發股票股利的樣本，共80個樣本點。實證結果如下：一、電子類股與非電子類股的股票股利宣告日當天平均異常報酬率具有明顯差異。二、電子類股的股票股利宣告，並沒有較非電子類股的股票股利宣告，產生較大的正異常報酬率。三、電子類股中，高股利支付率組的股票股利宣告，並沒有較低股利支付率組的股票股利宣告，產生較大的正異常報酬率。四、非電子類股中，高股利支付率組的股票股利宣告，並沒有較低股利支付率組的股票股利宣告，產生較大的正異常報酬率。

本篇論文主要探討股利支付率與未來獲利能力成長的關聯性。過去相關文獻專注在股利變化率與未來盈餘成長的關係，股利支付率的文獻則較少。本研究以1991至2016年台灣上市、上櫃公司為樣本，利用固定效果模型來進行分析，實證結果發現股利支付率與未來獲利能力成長的關係呈顯著正相關。本研究根據文獻在迴歸模型中加入成長機會代理變數來檢驗股利支付率與未來獲利能力成長的正向關係是否能以自由現金流量假說解釋，實證結果與文獻一致，說明當成長機會愈低，台灣上市櫃公司之股利支付率與未來獲利能力成長之關聯性愈強，透過將剩餘的自由現金流量以股利發放的形式返還予股東，能減少公司之代理成本，市場上的投資機會未受到市場的競爭而使報酬率高於預期，因此出現公司股利支付率愈高，未來獲利能力成長愈高的現象。 / This study examines the relationship between dividend payout ratio and the growth of future profitability. Previous literatures mainly focused on the relationship between dividend change rate and future earnings growth instead of dividend payout ratio. The sample of this study includes companies listed on Taiwan Stock Exchange and the OTC market from 1991 to 2016. Results of the fixed effect model shows that there is a significantly positive relationship between dividend payout ratio and the growth of future profitability. Proxy variables for growth opportunities are used in the　fixed effect model to further verify whether the positive relationship can be explained by free cash flow theory. Our results support the explanation, indicating that the positive relationship between dividend payout ratio and the growth of future profitability is stronger when growth opportunities are low. Companies can reduce agency costs by paying out dividends to shareholders, and the returns of investment opportunities on the market are unaffected by competition force, which results in the counter-intuitive phenomenon of higher dividend payout ratio and subsequent growth of future profitability.

Bhattacharyya（2007）建立一個連結企業管理階層薪酬與現金股利的模型。該模型指出在既定的可用現金下，企業管理階層薪酬與現金股利支付率呈負相關。本研究參考上述模型，以2005年至2008年國內上市櫃公司資料為樣本，使用Tobit模型檢視樣本公司高階經理人薪酬、董監事薪酬與現金股利支付率之關聯性。本研究實證結果符合上述模型之推論，亦即高階經理人總薪酬與公司之現金股利支付率呈顯著負相關。 　　本研究另將高階經理人薪酬區分為現金薪酬與股票薪酬，進行額外的分析，其結果顯示高階經理人之股票薪酬與公司現金股利支付率呈顯著負相關。換言之，台灣上市櫃公司（尤其高科技產業）常使用之股票薪酬合約，其性質具有長期激勵之效果。在公司既定的可用現金下，此種合約不但可激勵高品質的高階經理人選擇淨現值為正的投資方案，且可確保經理人不因短期投資方案而犧牲公司的長期利益。 / Bhattacharyya (2007) proposed a dividend payout model in which executive compensation is associated with the level of cash dividends. The model shows that for a given level of cash available for distribution, there is a negative　relationship between a company’s dividend payout ratio and its managerial compensation. This study applies the above model to a sample of the listed companies at the Taiwan Stock Exchange (TSE) and the Gre Tai Securities Market (GTSM) from 2005 to 2008. The Tobit regression results are consistent with the Bhattacharyya (2007) model’s prediction, i.e., the dividend payout ratios of sample firms have negative associations with their managerial compensations. 　　In addition, this study classifies executive compensation into cash and stock payments for further analyses. The results show that dividend payout ratio is negatively correlated only with the stock portion of executive compensation. It means that for a given level of available cash for distribution, the nature of stock compensation has the long term effects which not only encourage a company’s executives to invest more in the projects with positive NPV without sacrificing the company’s benefits, bus also leave less cash for　distribution as dividends.
