本文引援Peretto(1998b)的研發模型，假設人口數固定的情況下，進一步延伸設定知識外溢性分別處於研發、生產技術，探討不同技術設定對於經濟成長率及廠商家數的影響，亦即經濟成長率及市場競爭程度間的關連性。 在本文的模型內，可同時決定經濟成長率與廠商家數。模型顯示：（1）當生產與研發技術皆具有外溢性時，其對應的經濟成長率高於其他情況，而廠商家數與只有研發技術具外溢性時相同，（2）生產或研發分別具有外溢性時，經濟成長率與廠商家數相對於其他情況而言，皆須視外生參數而定，（3）生產與研發技術皆不具外溢性時，其對應的經濟成長率低於其他情況，而廠商家數則與只有生產技術具外溢性時相同。 就單一產業而言，外生參數變動導致廠商家數與經濟成長之間具有抵換關係，亦即市場競爭程度與成長率間具抵換關係。若從跨產業的角度來分析，當經濟體系內存在許多不同技術型態的產業時，其經濟成長背後的動力亦會隨著技術型態的相對比重而有所影響。

本研究透過代理理論並考量內生性因素來探討高階主管薪酬結構與企業研發支出間之關聯性。實證結果指出權益型薪酬與股票紅利佔個人總薪酬之比率均對研發支出有正向影響，此顯示出高階主管為增加股票紅利的價值，故會重視研發支出所帶來的效益，也較不會有刪減研發費用等短視行為。在股票紅利方面，當經理人持股比率越高時，其利益會和股東越趨於一致，故企業可以不用透過股份基礎報酬來減少經理人的短視行為，此論點支持利益收斂假說，因此企業應該重視經理人薪酬制度，進而設計出一套合理的薪酬制度來增加高階主管之工作誘因，並增進經理人與股東間共同的利益目標，用以減少代理問題與監督成本。 最後，本研究亦探討在2008年實施員工分紅費用化後，台灣企業是否會因應員工分紅費用化，而改變高階主管薪酬之結構。經由實證結果可知在員工分紅費用化之後，企業會因認列較多的薪資費用而降低盈餘，致使股價下跌且亦讓每股盈餘大幅稀釋，故會減少公司股份的價值，因而發放給高階主管較少之員工認股權、股票紅利與權益型之股份基礎的報酬，轉而給予較多現金基礎的報酬。 / This paper examines the interaction between corporate executive compensation structure and R&D investment decisions during year 2005 to 2008. Considering the endogenesis between compensation and R&D expenditure, that I use two–stage limited method. The empirical results indicate that the percentage of equity-based compensation and stock bonuses to total executive compensation exhibits positive influences on R&D investments, which support the hypotheses that the executives are rewarded based on changes in the stock price to induce a long-term focus on R&D investments. Besides, in respect of the percentage of stock bonuses, the result demonstrates that managerial ownership helps to align manager’s interest with the interest with of stockholder; therefore, corporations decrease the use of equity-based compensation to curb the myopic investment behavior, which supports the convergence of interest hypothesis. This suggests that corporations should design their executive compensation policy appropriately to motivate managers, and improve the alignments between managements and stockholders. Finally, the empirical results also show that after the mandating expensing of employee bonus expense in 2008, corporations recognize that equity-based compensation reduces earnings and dilutes shares price and earnings per share; thus, corporations use more cash-based compensation than equity-based compensation, such as stock option and stock bonus.

隨我國經濟發展與產業結構變遷，從經濟管制到市場自由，自勞力密集之製造出口至技術密集之產業升級，期間有不同階段之稅捐優惠作為引導。 研究發展活動具有外部正面性，同時有市場失靈之可能，私部門可能因此而不願投入、或投入不足之資源，進行研究發展活動。為獲得整體社會之最大利益，稅捐除作為財政工具，作為經濟目的之政策誘因之正當性也獲得承認。政府為促進民間投入研究發展，可能以直接補貼或提供租稅優惠方式給與鼓勵，以協助企業進行研究發展，降低跨足新興產業之進入障礙及營運風險。 但稅捐優惠之提供，乃對具相同負擔稅捐能力者，課以不同之稅捐負擔，以引導特定之作為或不作為，無可避免的違反量能課稅原則下的平等原則。何以相同負擔稅捐能力者，有不同之稅捐負擔，應有實質之說明理由。其成效與影響如何，是否達成制度上犧牲量能課稅原則所欲追求之目的，應與直接補貼接受相同程度之公開之監督與績效衡量。 就研究發展投資支出可抵減之稅額，未分配盈餘加徵百分之十部份乃為縮減營利事業所得稅與個人綜合所得稅之之實現時間差距，而研究發展投資抵減，則為分擔企業研發風險，鼓勵知識之累積，提升附加價值，兩者制定之精神互不相同，以研究發展投資抵減未分配盈餘加徵百分之十之「營利事業所得稅」，似有扞格，但兩稅合一後，營利事業所得稅在公司此一法律主體之稅捐負擔意涵已大幅下降。是以，就研究發展投資抵減未分配盈餘加徵百分之十之稅額部分，衝突程度亦獲得一定程度之解決。另外，所得基本稅額條例規定營利事業及個人皆需有一定之基本稅額負擔，此即所謂最低稅負制。所得基本稅額條例明確將研究發展投資抵減之金額計入營利事業基本稅額之計算，對之課以基本稅額，符合所得基本稅額條例施行之精神，乃合理之設計。 本文以表格方式整理方式，對照獎勵投資條例、促進產業升級條例與產業創新條例對稅基、稅率、稅額與時間歸屬之影響；針對投資抵減實務施行爭議，本研究則整理相關判決以供參考。 以上述三條例之演進趨勢而言，稅捐優惠之給予範圍已逐漸縮小，而改以直接補助或金融協助；技術開發補助與輔導；提供資訊管道、建構交易平台、整合業界、規劃工業區等行政協助，應用多元方式協助產業發展。 研究發展投資抵減之適用範圍、申請期限、申請程序、核定機關、施行期限、抵減率及其他相關實體事項，若立法之技術與資源已有相當累積，以法律位階就投資抵減作較具體之規範，應為立法機關所考慮。 / Abstract With the economic development and the changing in industry structure, from economic regulation to an open market, and from labor-intensive to technology -intensive, the government is guiding the market by tax incentive and other kinds of tool. Because R&D has positive externalities, barriers to entry and the possibilities of market failure, private sector may not willing to input resource for R&D. For social welfare maximization, the government may use tax incentive to encourage private sector to do R&D. By provide R&D Tax Credit or subsidy , the government can encourage the private sector to do more R&D. But providing tax credit will unavoidably conflict with Principle of Ability to Pay. There should be a reason for why people have the same ability to pay the tax pay different tax. The same supervise and performance evaluation must be done for tax credit and subsidy. For 10% surtax on Retained Earnings is to narrow down the time difference between the realized of corporation tax and individual income tax, and the R&D credit is for sharing risk of failure, encouraging research and development, and rising EVA, the tax which can be credited should not include surtax on Retained Earnings. But with the applying of Integrated income tax system, the conflict has been partly solved. For Alternative Minimum Tax, R&D expense can’t be credited is a reasonable design. This paper mainly focus on comparing the differences of tax base, tax rate, and income tax payable etc. in the Enactment of Encouragement Investment, the Statute for Upgrading Industry, and the Statute for Industrial Innovation. Also sued cases were collected to report any violations of existing R&D policies for future amendment concerns. The range of tax credit is shrinking, and is replaced by subsidies, industrial technology development programs, and the setting of science parks etc. And for principle of taxation under the law, The Statute for Industrial Innovation should be ruled in law by the legislative.

本文探討研發支出資本化與攤銷之理論，並以國內股票上市公司為實證對象。本研究使用聯立方程式及Almon lag procedure來檢測企業研發投資效益遞延之情形，然後以Feltham and Ohlson（1995）之評價模式，探討研發支出資本化與攤銷後之權益帳面價值與盈餘之特性，並探討研發投資是否為股票報酬之長期風險因素。本研究並以研發強度（研發費用對銷貨凈額比）區分高、低研發強度二組樣本，比較其與研發有關問題。 本文發現如下： (1)研究發展支出效益遞延實現之現象，似乎存續自第三年開始至未來數期（第四、五年）；平均而言，一元之研發投資可於未來4-5年產生2元以上之獲利，高研發強度廠商則有3元以上之獲利；而低研發強度之公司，研發支出獲益則不顯著的於研發初期二年實現。 (2)在股票評價模式中，高研發強度廠商之研發支出採取資本化，對模式解釋能力較高；而低研發比例（強度）廠商之研發支出則採取費用化，「似乎」對模式解釋能力較高。 (3)目前「一般公認會計原則」對於評價模式的解釋，對低研發強度的廠商之解釋能力較高；反之，對高研發強度廠商較不適用。 (4)研發資本存量對市場比率為股票報酬之長期風險因素。 / This study analyzes the theory of capitalization and amortization of R&D expenditures. This study uses the simultaneous equations and Almon lag procedure to examine whether earnings reflect benefits from past R&D expenditures of public firms in Taiwan. Based on asset valuation model generated by Fetham and Ohlson(1995) and Bernard (1995), this study examines the properties of coefficients of parameters of valuation model and explainary power. In addition, this study estimates the R&D capitalization, and tests whether the R&D capitalization is the long risk factor of stock return or not. Moreover, this study groups sample firms into high or low intensity groups by R&D intensity (R&D expenses-to-sales ratio), and compares the above issues of capitalization of R&D expenditures. The major findings of this study follows: (1)Earnings almost reflect realized benefits from R&D, but there are two years time lag. On average, every one N.T. dollar invested in R&D will produce 2 N.T. dollars profits during four or five - years period. In the high R&D intensity group, every one N.T. dollar invested in R&D will produce 3 N.T. dollars profits in future. On the contrary, in the low R&D intensity group, the benefits of R&D outlays are insignificantly reflected in the first two years. (2)The explainary power (Radj2) of valuation model of R&D capitalized in the high R&D intensity group is higher than that of in the low R&D intensity groups. (3)The relevance of stock valuation generated by present GAAPs for the high R&D intensity group is lower than that of the lower R&D intensity group. (4)The R&D capital-to-market values ratio is the long risk factor of stock returns.

由於資訊科技的發達，使全球資訊的分享加速，一方面使得企業創新的刺激源源不絕，另一方面也使得消費者的需求慾望越來越廣，造成產品生命週期不斷縮短，在現今的環境下，企業若要長久經營甚至維持成長，就必需積極從事創新之新產品開發。雖說新產品或技術的創新對企業的貢獻相當大，但研發專案往往存在高度不確定性且耗時耗力，一旦專案失敗，亦會對企業造成相當程度的傷害，導致許多企業望之卻步。因此，1960年代初期，Mansfield(1968)等學者開始從事研發支出費用與產業或公司生產力相關性的研究。其後，由於財報資料取得的方便性與客觀性，加上個別研發專案的效益較難追蹤、亦難以評估，大多數研發投入與研發績效相關的研究，首先，在變數上都是以財報上的財務數字為基礎，如研發費用、研發密度、公司獲利、營收等；其次，在研究個體上則是以企業整體為主。然而，過去許多研發投入與績效相關之研究，不論在投入面或效益面皆提出了許多非財務性的項目，此外，在現今即將邁入第四代研發管理的環境下，組織企業的研究發展工作多以「專案」的方式來進行，而非以年度企業整體預算進行管理。綜合上述兩點過去此類研究與實務上之落差，本研究採用經濟部工業局「主導性新產品開發計劃」之計劃成效追蹤問卷資料，以個別研發專案為研究對象，並將投入面擴大區分為成本、人力、時間三個構面，探討研發專案投入對非財務面之技術產出及財務績效之影響，期能彌補過去此類研究與實務上之落差。 本研究依照研發專案投入所產生之非財務與財務績效構面，分成兩大研究主題，研究結果顯示： 一、研發專案投入對技術產出之影響：專案投資金額對專利權與創新技術數有顯著正向的影響，專案研發人員之教育程度只對創新技術數有顯著正向之影響，研發時間與專案技術產出皆無顯著相關。 二、研發專案投入對財務產出之影響及其遞延效果：專案投資金額與專案研發人員之教育程度對開發產品銷售額具有顯著之正向影響，且從產品銷售第一年起，沒有時間上的落差，且專案投資金額之影響可延續三年，專案研發人員之教育程度之影響可延續兩年，研發時間與開發產品銷售額無顯著相關。 此外，吾人並針對實證結果與實務界人士進行訪談，瞭解與假說不符者之原因，結果發現：專案研發時間較長，不完全是因為企業願意投入較多的心力，有很大的可能是研發瓶頸的發生與研發人員的不效率，這些部份不但對專案產出沒有顯著貢獻，還可能危害專案的成功。 / As a result of the progression of information technology, the speed of information sharing is getting higher and higher. On one hand it makes companies get the stimulation of innovation more easily than before, on the other it also makes the desire of customers becomes wider and wider. Thus, the life cycles of all products in the world then become shorter and shorter. In this environment, companies who want to survive or even get growth have to do their development and research activities more aggressively than before. Although the benefits of R&D is great, lots of companies still shrink back at the sight. That’s because of the high uncertainty of R&D and the needs of huge amount of time and money, and companies always get incredible harm once they fail. Therefore, many researchers have tried to clarify the relationship between R&D inputs and R&D performance. Due to the accessibility and objectivity of financial report, the past researches in this field always used the information from financial reports, and set their research objects as the whole companies. But many researchers have pointed out that there are not only financial inputs and outputs of R&D activities but also non-financial ones. In the global trend to 4th generation of R&D management, R&D organizations have changed their management way form total budgeting to project management. To eliminate these two gaps between theory and practice, in this research we use the questionnaire data of Leading Product Development Programs from Industrial Development Bureau Ministry of Economic Affairs to make our research stand on a project view point and get other non-financial inputs and outputs data that we can’t get from financial reports. Hope we can earn more practical results to help companies making their decisions of R&D activities. According to the two perspectives of R&D project performances, non-financial and financial, we separated this research into two subjects, the results showed that: 1. The effects of R&D project inputs on technical outputs: we found that the project dollar investment has significant effect on the number of patents and innovative techniques, and the education degree of the project’s R&D engineers only has significant effect on innovative techniques but on patents. On the other hand, R&D time of the project has no significant effect on both patents and innovative techniques. 2. The effects of R&D project inputs on financial performance, their time-lag effect and their continuity: we found that project dollar investment has significant effect on sales of the product that developed from the project since the first year it was sold, which means the time-lag doesn’t exist in this situation, and this effect can last for three years or even more. The education degree of the project’s R&D engineers has significant effect on sales of the product that developed from the project, from the first year it was sold. So, there is no time-lag, but this effect can only last two years. Besides, R&D time of the project has no significant effect on any year’s sales of the product that developed from the project. Finally, we have interviewed some practitioners discussing about our results that were not consistent with our hypotheses. According to their opinions, the reason why some projects spend longer R&D time is not just because those companies intend to pay more effort on those projects. It also includes the inefficiency of R&D engineer and the bottleneck of that project. These inefficiency and bottlenecks are not only non-value-added but also sometimes harmful to a R&D project. That’s why we found in this research that there is no significant relationship between R&D time of a project and its performances, neither financial performances nor non-financial ones.

本研究係研究技術策略規劃的規劃過程，由探討技術策略規劃的內容模式，歸納出技術策略規劃過程的幾個重要課題及活動，包括技術狀況的瞭解、關鍵技術的掌握、技術預測、技術來源、技術需求分析、技術創新機會、技術策略和經營策略的配合、技術策略融入企業整體策略規劃，並建立技術策略規劃的程序過程。 　　本研究以國內重視科技及研發的公司為研究對象，探討這些企業技術策略規劃的實際程序，以及這些企業在技術策略規劃重要課題活動的管理，最後並嘗試建立一技術策略規劃的整合性工具方法－技術策略規劃檢核表，以為一個公司有心從事技術策略規劃的輔助性工具。 　　本研究的結論包括：公司型態影響公司的技術策略規劃，跨國公司集團、或公司集團的子公司，技術策略規劃時自由度較低，本土公司技術策略規劃時自由度較高；經營資源多的公司，在從事技術策略規劃時較能不受限制，經營資源少的公司限制多；創新型的公司技術策略規劃的過程，強調快速、彈性，製造型的公司技術策略規劃的過程，強調有步驟、循序漸進；技術策略規劃應由公司的事業中長期計畫、研發中長期計畫展開，確保技術策略規劃融入事業整體規劃中。

本文的研究意旨在於探討企業所投入的研究發展支出及資本支出對經營績效及股價報酬產生何種影響，希望能提供給企業經營者在決定研發政策或資本支出決策時參考。 本論文以國內上市櫃公司（除金融服務業外）作為研究樣本，並以2001年至2011年間為實證期間，進行迴歸模型分析，探討研發支出、資本支出等重大支出對於公司經營績效及股價報酬所產生的效果，並探討國內電子次產業如半導體產業、光電產業、電腦周邊產業及電子零組件產業在研發與資本支出對經營績效與股價報酬的影響差異度；本論文在公司經營績效及市場價值的衡量指標，係以公司之資產報酬率、股東權益報酬率、營業毛利率、營業淨利率、營收成長率及公司Tobin’s Q值與股價報酬等作為衡量指標。 實證結果發現： 一、 就全體產業而言，研究發展支出對於企業之營業毛利率、營業淨利率及Tobin’s Q值有顯著正相關，但對於企業之營收成長率、資產報酬率、股東權益報酬率以及公司股價報酬率等項目並未出現顯著相關性；資本支出對企業之資產報酬率及股東權益報酬率則出現顯著負相關，同時資本支出對企業Tobin’s Q值及股價報酬率出現顯著負相關，但對於企業之營收成長率、營業毛利率、營業淨利率等未出現顯著相關性。 二、 針對電子次產業實證結果： 1. 針對半導體產業實證發現，研究發展支出對於公司資產報酬率出現顯著正相關，資本支出對於公司Tobin’s Q值及股價報酬率則呈現顯著負相關。 2. 針對光電產業的實證發現，研究發展支出對於企業經營績效指標包括公司營收成長率、營業毛利率、營業淨利率、資產報酬率及股東權益報酬率等，全數呈現顯著正相關；而資本支出對於公司Tobin’s Q值或股價報酬率呈現顯著正相關，但對於營業毛利率、營業淨利率、資產報酬率及股東權益報酬率等則呈現顯著負相關。 3. 針對電腦週邊產業的實證發現，研究發展支出對於公司營收成長率、營業淨利率、資產報酬率、股東權益報酬率及公司Tobin’s Q值等皆呈現顯著正相關；而資本支出則對於公司營收成長率出現顯著正相關。 4. 針對零組件產業的實證發現，研究發展支出對於公司營收成長率、營業毛利率、營業淨利率、資產報酬率、股東權益報酬率、公司Tobin’s Q值及股價報酬率等全數呈現顯著正相關；而資本支出對於公司營業毛利率、資產報酬率及股東權益報酬率等出現顯著負相關。 / This research mainly examines the related effect of R&D expenditure and capital investment on corporate performance and company’s stock price. The results of this study are trying to offer reference opinions to corporate executive officers that will make R&D or capital investment decisions. In this study, the database includes the listed companies in Taiwan Stock exchange except the finance industry from 2001 to 2011. We adopt R&D expenditure and capital investment as the independent variables of evaluating of corporate performance and company’s stock price, and also choose the growth rate of sales, the operating margin ratio, the net profit margin ratio, the return on total assets, the return on equity, Tobin's Q Ratio and company’s stock price as the dependent variables. The results of this investigation could be summarized as follows: 1. For all targeted industries, R&D expenditure had positive, significant influence on the operating margin ratio, the net profit margin ratio and Tobin's Q Ratio. Capital investment had negative, significant influence on the return on total assets, the return on equity, Tobin's Q Ratio and company’s stock price. 2. For Semiconductor industry, R&D expenditure had positive, significant influence on the return on total assets. Capital investment had negative, significant influence on Tobin's Q Ratio and company’s stock price. 3. For Optoelectronics industry, R&D expenditure had positive, significant influence on growth rate of sales, the operating margin ratio, the net profit margin ratio, the return on total assets, the return on equity. Capital investment had positive, significant influence on Tobin's Q Ratio and company’s stock price. 4. For Computer peripheral industry, R&D expenditure had positive, significant influence on growth rate of sales, the operating margin ratio, the net profit margin ratio, the return on total assets, the return on equity, and Tobin's Q Ratio. Capital investment had positive, significant influence on the growth rate of sales. 5. For Electronic components/material industry, R&D expenditure had positive, significant influence on growth rate of sales, the operating margin ratio, the net profit margin ratio, the return on total assets, the return on equity, Tobin's Q Ratio and company’s stock price. Capital investment had negative, significant influence on the operating margin ratio, the return on total assets and the return on equity.

區域技術創新能力是展現區域將知識轉化為經濟的能力，是區域競爭力的重要內容。由於區域創新能力是造成中國各區域經濟發展差距的主要原因之一。本研究採用中國之上市公司為研究對象，探討公司創新活動的揭露與中國各省（自治區、直轄市）創新能力對分析師預測行為及分析師預測跟隨人數之影響。由三個面向檢視區域創新能力：研究與試驗發展全時人員當量增長率(REGTH)、政府研發投入占GDP比例(GIGDP)、每百萬人平均發明專利授權數(AVPAT)。研究結果發現創新活動揭露越多之公司，分析師之預測誤差程度越低、分析師之離散度越高且能吸引越多分析師對公司做預測。區域創新能力指標REGTH越高地區，分析師預測跟隨人數越少；區域創新能力指標GIGDP越高地區，分析師之預測誤差程度越低、分析師之離散度越低、分析師預測跟隨人數越少；區域創新能力指標AVPAT越高地區，分析師之預測誤差程度越低、分析師之離散度越低、分析師預測跟隨人數越多。 / Regional innovation capability is an important competitive ability to improve the economic development in China. Using a sample of Chinese listed companies, this study investigates the extent to which innovation disclosure at the company level and regional innovation capabilities affect analysts’ forecast characteristics in terms of forecast error, and forecast dispersion, and the number of analysts’ following. The indicators of regional innovation capabilities are the growth rate of R&D full-time equivalent personnel (REGTH), regional government's investment in R&D per GDP (GIGDP), and average of innovation patent authorized per millions of people in one region (AVPAT). The results indicate that firms with more innovation disclosures improve analysts’ forecast error, and regions with higher GIGDP and AVPAT also improve analysts’ forecast error. For firms with more innovation disclosures increase analysts’ forecast dispersion, and for regions with lower GIGDP and AVPAT increase analysts’ forecast dispersion. I also find firms with more innovation disclosures attract more analysts’ following, and regions with higher REGTH and GIGDP have less analysts’ following, while regions with higher AVPAT attract more analysts’ following.

本研究主要目的為探討產業過去之購併活動，對公司的研發投入的影響。產業的購併活動活躍與否，可視為此產業中資產的流動性衡量，根據Phillips and Zhdanov （2012）所使用之方式，利用產業過去的購併交易所計算出變數，可用以解釋公司的研發投入。本文有別於傳統之樣本分類法，而是採用不同的變數來衡量產業分類，藉以分析同業購併、異業購併以及產業整體購併對公司研發投入的影響。從實證結果發現，當過去的同業內購併活動越盛行時，公司的研發投入越高。而公司的研發投入，又與公司之規模大小有關，隨著公司規模大小不同，購併活動對研發投入的影響程度也隨之改變，隨著公司規模越大，受到的影響則越小，具有規模效應。本研究同時考量產業需求變動以及競爭程度對公司研發投入的影響，實證發現公司研發投入與產業需求及競爭程度為正向關係，且同樣具有規模效應。 / The objective of this study is to analyze how an active acquisition market affects Taiwan firms’ incentives to conduct R&D. It follows Phillips and Zhdanov（2012）that using the value of past M&A activity in the firm’s industry to captures the historical liquidity of an industry’s assets. Different from other studies which usually split sample into different groups to examine inside- and outside-industry, this study use three variables to measure how M&A activity in inside-, outside- and whole-industry affect firms on conducting R&D in different ways. According to the empirical results of the regression analyses, we find that firms’ incentives to conduct R&D increase with inside industry M&A activity and the effect is stronger for small firms than large firms. We also find that firms’ R&D are positively correlated with industry demand and competition, and both of these effects are also stronger for small firms than for large firms.
