本文以一個簡單賽局理論模型為分析依據,探討企業間的自製或是外包策略對整體社會福利的影響。 傳統經濟理論分析告訴我們自製策略可以解決雙重邊際化的問題。但在本文我們舉出一個反例，亦即當存在研發的可能及上下遊市場的研發外溢效果時，垂直整合可能會造成廠商過度研發的情形，最終產生整體社會福利不效益情形。 / In this paper, we set up a game-theoretic model, in which the whole industry is composed of a downstream monopolist and two upstream firms. This paper discusses the major debate in a firm’s market strategy: to make or to buy the components it needs. Traditionally, economic theories told us that vertical integration strategy (make strategy) can solve the problem of double marginalization and hence increase profits as well as social welfare. Nevertheless, this result does not necessarily hold when R&D possibility is introduced. We show that when there is downstream to upstream R&D spillover, vertical integration may result in an over-investment in R&D from the social standpoint. This result may shed some light on the rationale behind recent antitrust rulings.

本研究旨在以Spence和Robbins（1992）工作狂熱建構中的內在驅迫因素和工作樂趣因素為基礎，並加入外在驅迫因素，來探討高科技研發人員過度工作的不同因素對於工作時數以及健康生活工作等層面變項的預測力或關聯性，最後由因素劃分出過度工作者類型，並比較不同類型過度工作者的差異性。本研究採問卷調查法，以249位台灣北部地區的高科技研發人員為樣本以及52位高科技行政人員為工作時數的對照組。研究結果發現：（1）研發人員與全國製造業工作者及高科技行政人員相較下，有顯著的過度工作現象。（2）外在驅迫因素意指源自專業工作環境而迫使個體長時數工作的各影響因素。針對研發人員，包括工作負荷過重、產業特性、組織文化酬賞等外在驅迫因素，以及內在驅迫因素，皆對過度工作具有顯著的預測力。而外在驅迫因素對研發人員過度工作的相對預測力高於內在因素。（3）對於健康生活工作三層面的影響性而言，內在因素中的內在驅迫有廣泛不利於三層面的顯著影響性而屬於健康生活工作的危險因子，內在因素中的工作樂趣則相對地於三層面皆有顯著助益而在三層面居於保護因子的角色；外在驅迫因素中的工作負荷過重，對於生活層面有顯著的不良影響，但對健康和工作沒有顯著影響。（4）辨識出三類型的過度工作研發人員，其中內在驅迫高工作樂趣低的「被驅迫狂」在各層面皆有最不利的行為表現，屬於積極的健康定義下的高危險群，內在驅迫高工作樂趣高的「幹勁狂」則較「被驅迫狂」有顯著較高的生活滿足，內在驅迫普通而工作樂趣高的「幹勁者」雖然長時數工作，但各層面狀況反而有優於全體研發人員平均值的傾向。最後，本研究針對上述研究結果做更深層的探討，並說明在個人層次和組織層次實務上的意涵。 / Two internal factors, “driveness” and “enjoyment of work” from the workaholism model of Spence and Robbins (1992), and “external force” factors were adopted to investigate the phenomenon of excessive work (defined as long hours of working) in the population of high-tech R&D professionals. The purpose of this study is to clarify the effects of these factors on high-tech R&D professionals’ working habits, as well as on their health and life styles. These factors were used to categorize high-tech R&D professionals further. The results showed (1) R&D professionals worked significantly longer hours than high-tech administrative staff and workers in manufacturing industry. (2) “Work overload”, one external force factor, compared to other factors, predicted best to R&D professionals’ hours of working. Moreover, the amount of variance explained by the external force factors was relatively larger than the internal factors. (3) Driveness was constantly found to be a risk factor for one’s holistic health, whereas the enjoyment of work was found to be a protective factor. The third factor, work overload, influenced one’s health only on one’s social life. (4) Three types of overworkers were identified: the nonenthusiastic workaholics (NWs), the enthusiastic workaholics (EWs), and the enthusiasts (Es). Among these overworkers, the NWs acted most consistently with the indicators of unhealthiness, showing that the NWs may be most vulnerable to health complaints, unsatisfied social life, and inefficient work habits. The EWs, though acted similarly as the NWs, were not as extreme as the NWs and had higher life-satisfaction than the NWs. As for Es, who also worked long hours, their health complains were the least of all workers and they had relatively healthy life styles than the other two kinds of workers. Implications of the internal and external factors on the high-tech R&D professionals, as well as the typology of the overworkers, were discussed.

台灣的高科技研發設計產業長期以來一直享有較高的競爭優勢以及令人稱羨的利潤，但近幾年來，在面對全球性競爭與快速變遷的環境下，原先具有的高品質及低開發成本的優勢有逐漸喪失的情形。而企業為了維持原有的競爭優勢，除了加緊腳步在研發技術的創新、提供服務的效率以及營運成本的控制上找出最好的方法及策略外，而如何計算產品成本，如何有效訂價，更為企業迎戰此一競局的重要考量。 由於傳統的成本制度無法滿足快速變遷的製造環境，高科技研發設計產業亟需新的方法以適時的提供相關成本資訊，做為決策之用。而作業基礎成本制度(Activity-Based Costing System, ABC)經過學術界的大力推廣及實務上不斷的經驗累積，大多認為此一制度不僅可以減少成本扭曲，更重要的是可以協助管理者進行較佳的成本控制，增加企業營運的效率，以及進一步可以輔助產品的訂價及競爭策略。 因此，本研究係以國內某高科技軟/硬體研發設計公司為研究對象，透過個案研究及作業基礎成本法之探討，分析高科技研發設計公司成本組成及影響成本活動的因素，並建立其關聯，藉此提出一套可供研發設計公司參考之成本分析架構與模式，並進而協助相關企業在產品研發及訂價方面做出最好之決策。 / The R&D design industry of Taiwan have enjoyed high competition advantages & high profit margin for a long time. But in recent year, under global competition & environment of rapid change, those advantages have lost gradually. In order to maintain the original competition advantages, enterprises need to step up the step to find out the best method and tactics in R&D innovation, service providing of high efficiency and control of operating cost. Besides, It is also the important consideration for those companies to think about how to calculate the product cost and set up the pricing strategy. Because the traditional cost system cannot satisfy the diversified manufacturing environment, R&D design industry tremendously need a new cost method which provides decision-makers with up-to-date, complete, and reliable cost information. Activity-Based Costing System (ABC) has been approved by academic study & implemented by a lot of company. Mostly think that this system cannot merely reduce the cost to distort, the more important thing is that can help top managers to control better cost, increase the operating efficiency, and program the better pricing strategy. This paper studies how a software/hardware design company by adopting the activity-based costing (ABC) system traces and analyze all of the cost elements associated with research & development activities. The main purpose of this study is trying to use ABC costing system to build a cost model for future application in the R&D design industry and hope this study can help relevant enterprises to make the best decision in the product development and establish the competitive pricing strategy.

本文以台灣工具機產業為例，來分析國家產業政策與公共研發機構的轉變，以及對工具機產業發展的影響。1990年代以後，世界上先進工具機國家均逐漸朝向高階工具機技術發展，台灣工具機產業亦面臨南韓和大陸等工業化國家的追趕，而不得不進行技術學習和升級。此外，台灣工具機產業有90%是屬於中小企業，但是高階工具機技術複雜、研發困難，費用龐大，企業多無法負擔。因此，本文欲探討國家角色，亦即產業政策與公共研發機構對台灣工具機產業發展的影響。 本文的研究成果可以歸納如下：第一，國家逐漸扮演起產業輔導者的角色，產業政策與工具的轉變則是於1980年代起廣泛運用各種政策工具達11種類型，1990年代以財政補助為主要誘因鼓勵業界投入技術研發，2001年以後則是將組織聯盟作為主要的政策工具，為台灣工具機產業的發展開啟了另一種新的技術學習型態。其次，機械所的研發策略轉變為高階工具機技術與工具機關鍵組件技術的雙軸技術研發模式。中區技術服務中心普遍獲得中部工具機業者的信任與肯定，也使得機械所能夠順利協調廠商形成整合性研發聯盟。第三，整合性研發聯盟促使廠商水平合作共同降低研發成本與風險，並藉由產業上下游整機的垂直整合，提升專業模組廠的技術能力，降低模組成本，和提升整機廠的競爭力。 / This thesis is about the upgrading of Taiwan’s machine tool industry and the role of the state on this industry’s transformation. Taiwan’s maching tool industry faced an urgent challenge after the 1990s, as the counterparts in advanced countries have made rapid progess on technological level, while other industrializing countries, such as South Korea and China, had also been catching up quickly. Due to the fact that most of the firms in Taiwan’s machine tool industry were small and medium-sized enterprises that were not affordable financially to do cutting-edge technology research, the burden therefore fall upon the state. This essay has three major findings. To begin with, the state has gradually become an instructor in helping the development of the industry. The state’s role has changed from being an aloof promoter by using various policy instruments to help developing the industry as a whole, to utilizing fiscal incentives to encourage enterprises to engage into R&D activities, and to encouraging the formation of industrial consortia after 2001. Secondly, the role of the major pubic research institute, the Mechanical Industrial Research Laboratories（MIRL）of the Industrial Technology Research Institute has changed from a remoted research oriented institute to one that engage heavily with local firms, from paying attention only to develop new machine models to ally with local firms to develop core components in the machine tool. Thirdly, the formation of R&D alliances, led by MIRL, has largely upgraded the capability of the domestic enterprises. This not only shows in the upgrading of local firms’ technological competence, but also in the improvement of organizational capability of specialized module suppliers and, the reduction of cost structure of the products.

隨著全球化的發展，對外投資不僅在國際經貿中所扮演的角色愈來愈重要，型態也愈來愈多元，呈現出與過去大不相同的特性與風貌。這樣的發展趨勢，再度引起學者對廠商對外投資的影響效果產生興趣。過去有關對外投資影響效果的文獻，主要是以探討對外投資對地主國經濟發展的影響為主，探討對母國或母公司影響的文獻則不多，特別是開發中國家的廠商對外投資對母國影響的研究更是付之闕如。為了彌補此方面文獻之不足，本研究利用台灣製造業1987-2003年的廠商資料來探討廠商對外投資對其技術升級之影響。 廠商對外投資對母國經濟影響的相關議題在台灣一直受到持續的關注，1991年政府開放廠商赴大陸投資之後，該議題更是引發熱切的討論。部分學者擔憂廠商對外投資後將造成國內產業的空洞化；但有另一部分的學者則主張，台灣只要持續技術升級及產業升級就可避免空洞化的危機。有鑑於此，本研究利用三個經濟指標，研發支出、生產力與效率，及技能提升(skill-upgrading)來檢驗不具競爭優勢的產業或附加價值鏈外移，是否有利於台灣進行技術升級。 本研究首先建立了一個理論模型來探討廠商對外投資對其國內研發活動的影響。研究結果顯示，廠商對外投資對其國內的研發支出可能同時產生兩個相反的影響效果，即互補效果及替代效果。互補效果主要來自於廠商對外投資後的「規模擴大效果」，而替代效果的發生則會因廠商對外投資動機之不同，而有不同的來源管道。 本研究實證模型的創新之處在於利用propensity score matching的配對方式搭配difference-in-differences的估計方法來控制實證研究中常會出現的自我選擇誤差(self-selection bias)及互為因果(causality)的問題。本研究採用了四種不同的配對方式來建構對外投資廠商的配對樣本，並發現Nearest available matching within calipers的配對方式可以產生最佳的配對效果，在不犧牲太多樣本數的情況下，顯著縮小對外投資廠商在對外投資前與無對外投資廠商的特性差距。 本研究的實證結果發現，僅管對外投資廠商，特別是赴開發中國家投資的廠商可能對母國的就業造成不利的衝擊，但卻能夠顯著提高母國的研發支出、技術效率及勞工技能，顯示廠商對外投資確實有助於台灣的技術升級。研究結果認為台灣政府應重新思考產業政策及社會福利政策的制定方向，以解決這些新的經濟議題。 / Foreign direct investment has played an increasingly important role in the world economy and, as a consequence, an immense amount of research has investigated its determinants and effects. However, while previous studies have focused on the impact of inward FDI on the host countries, there has been relatively little research on the impact of outward foreign direct investment (OFDI) on the home countries in general, and on developing economies (LDCs) in particular. To fill this gap in the literature, this thesis investigates the home-country effects of the OFDI activity of Taiwanese manufacturing firms. To be specific, the impact of OFDI on the investing firms’ domestic R&D spending, productivity and efficiency, employment and skill-upgrading is examined. A theoretical model is developed to examine the relationship between OFDI and domestic R&D activity. It is shown that OFDI could induce two opposing effects on domestic R&D spending, namely, a complementary effect and a substitution effect. The complementary effect arises mainly due to the “sales-increasing effect” of overseas investment. Substitution effects might arise from different channels depending on FDI motives. Firm-level panel data covering the period 1987-2003 are used in the empirical analysis. The novelty in this thesis is the application of a propensity score matching approach combined with the difference-in-differences method to control for the possible selection bias related to the empirical analysis. Four different matching methods are used to construct matched samples of Taiwan’s OFDI firms. The empirical results reveal that, although Taiwanese overseas investment, especially the investment in LDCs, reduces domestic employment, it stimulates investing firms’ domestic R&D spending, technology efficiency and skill intensity. This implies that while the OFDI activity of Taiwanese firms has brought about a positive effect on their technological upgrading, which is beneficial to the industrial development and resource allocation of the economy, the recent increase in the unemployment in Taiwan could to some extent be attributed to the OFDI activity. It also suggests that the Taiwanese government might need to reconsider its industrial policy as well as social welfare policy in order to deal with these new economic issues.

2007 年1 月9 日的MacWorld 活動中，Apple 公司的執行長在其每一屆Macworld 活動都會給予的演說 (Keynote) 中，介紹了一款Apple 公司最新的、具革命性的研究成果－iPhone。iPhone 隨及引爆了話題，並在2007 年 7 月上市時引爆了搶購熱潮，這是第一款能讓手機廠商和營運商分享利潤的手機，也是極少數的一款毛利高達50%以上的手機，更直接影響了整個手機產業。本研究從iPhone 的產品、技術探討iPhone 包含軟體、硬體的研發成果暨智慧財產，從商品化與商業模式的角度試圖討論Apple 公司如何以手機產業的新進入者而推出高附加價值的手機並在短時間內建立品牌，進而與營運商分享利潤，更以手機廠商的身份建立內容服務平台而創造高價值。最後，本研究將總結Apple 公司iPhone 研發成果與智慧財產的商品化與商業模式，以及iPhone 為產業帶來的衝擊，並給予台灣廠商幾點建議，僅供參考。 / In the Keynote of Macworld 2007 on January 9th, Steve Jobs, the CEO of Apple Company introduced the latest and revolutionary product of Apple Company whitch is actually a mobile phone, and its name is iPhone. The term“iPhone” was getting hot soon. On Junly 29th, iPhone was onto the market, and its sales soared in the market.

台灣高科技代工製造業在全球攻城掠地，以強大的規模經濟為出發，在國際上以成本競爭建立起今日強大的地位，有別於這些檯面上的大型高科技廠商，其實台灣還有另外一群占據了利基市場的中小型高科技廠商，他們沒有龐大的土地、沒有寬廣的廠房、沒有動輒破萬的員工數，沒有精密計算的財務槓桿，他們運用深耕利基市場的決心，創造了台灣的另一種企業神話。 本研究以此出發，選定利基產業中最具代表性的安全監控產業作為研究對象，從中選出兩間獲利能力最強的代表廠商奇偶科技與陞泰科技，以深入訪談的方式了解兩間個案公司建立核心能力的途徑，並利用哈佛大學Dorothy Barton(1998)出版的專書「知識創新之泉-智價企業的經營」中所指出的核心能力建構模式加以分析兩間個案公司之所以能形成強大核心能力的關鍵因素。 透過二手資料的蒐集與深入訪談，本研究認為兩間個案公司之所以能形成強大、特殊的核心能力，主要與其明確的研發策略、對市場需求的反應與創辦人之背景高度相關，透過創辦團隊引進獨特的經營哲學，於此哲學之上建構具體的研發目標，輔以快速的蒐集市場資訊、與使用者互動擷取需求的機制，個案公司得以主宰安全監控產業。 本研究也指出了整套的核心能力建構流程，供其他位於利基產業的廠商參考，期許台灣未來會出現更多這樣優秀的小規模科技廠商。 / Taiwanese high-tech manufacturing firms stormed the global market with low cost production capability and built solid market share. But there are still some other small Taiwanese high-tech firms that focus on niche markets. They don’t need big assets and large amount of employees, they don’t even use financial leverage to expend their operation. What they depend is the long time focus strategy that assured the high profit and non-replaceable status in their industry. Surveillance digital video recorder market is one of this kind of niche market. We chose two representative companies-Geo Vision and AVTech to do further case study and adapt the core capability building model which published by Prof. Dorothy Leonard Barton in the book “Wellsprings of Knowledge”to demonstrate the way this kind of niche high-tech companies build their core competence. Through this research, we found that the companies built their core capability base on the same pattern. Joint product development with users and market information screening made the case companies learn how to set a R&D goal that fits the expectation of users. Based on this goal, the case companies built their own R&D capabilities with different philosophy that their founders believe to realize the product concept. Through this pattern, the two case companies dominant the DVR industry. In this research we also found that the way they build their core capabilities is highly correlated to the back ground of their founder teams Moreover, we conclude the findings and integrated them into some simple ideas that other companies can adapt to build their own core capabilities.

隨著產業與經濟的全球化的浪潮下，「研發」與「創新」成為我國科技產業對抗全球的競爭壓力與推動組織營運的重要後盾，在新產品不斷推陳出新的帶動下，愈來愈短的產品生命週期，以及愈來愈多變的顧客需求，「速度」成為企業取得競爭優勢的關鍵因素，因此，我國企業紛紛透過導入產品生命週期管理（PLM）系統以縮短產品開發時程，使企業掌握新產品上市的先機。此外，透過PLM系統快速連結與蒐集研發知識，有助於企業實踐知識管理，加速組織與科技的融合與智慧財產的傳承，二十一世紀是知識經濟時代，企業能活用個人與組織內、外部的知識，則可創造價值並提昇企業競爭力。PLM系統使組織內研發之知識可有效的管理，並運用逐漸累積的資源形成的珍貴之研發知識，有效整合與串連成組織重要的知識資產；然而，知識管理之推展除資訊系統外，亦需要組織活動的配合。 本研究同時從組織與資訊科技（PLM）兩構面來探討研發單位的知識管理活動，旨在剖析台灣科技公司採用PLM系統下的知識管理活動，並瞭解影響研發知識管理的關鍵因素。本研究採個案研究法，首先經由文獻回顧導出實證研究的觀念性架構，再以此理論觀念模式為主軸進行個案訪談，實地深入訪談四家科技公司，瞭解其研發知識管理活動及運作模式。 本研究所得到的初步研究發現包括：（1）在研發知識管理推行實務上，企業需同時重視組織與資訊科技兩構面的作為，並將兩者平衡使知識管理達到真正的效益；（2）企業的知識分享文化與高階領導者態度等內部因素，對於研發人員的知識管理活動具關鍵影響力；（3）績效評估制度知識管理目標的配合，有助於知識管理效益的提昇；（4）企業研發創新的程度影響其知識創造的來源；（5）企業透過供應鏈的多元合作關係，形成知識創造的網路關係；因此，品牌廠商與代工廠商兩者的知識管理活動具有相依性；（6）企業透過PLM系統的採用將知識管理結合於作業流程之中，並使研發過程中個人之知識轉化為組織之知識；（7）企業的知識管理策略影響其知識擴散之作為。本研究最後並對企業經理人與後續研究者分別提出實務上與研究上之建議。 / Taiwanese high-tech industry has been emphasized the value of R&D innovation since 2000 in order to survive under the strong competition in globalization environment. The capability of innovation and efficiency of product development have been on the highly priority of companies. Hence, Taiwanese companies implement the product lifecycle management (PLM) system to improve product development schedule. Knowledge is an important intangible asset for companies in the 21th century. Because of PLM system, companies could manage R&D knowledge through collecting and linking R&D project or event. However, the promotion of knowledge management could not exist without the information systems and organization activities. This article considers the knowledge management activities from organizational and technical aspects. The purpose of the research is to examine the knowledge management of R&D division under the implementation of PLM system, and find out the key factors which influent R&D knowledge management. The research adopts four Taiwanese high-tech companies as Case Studies and has interviews with managers to understand knowledge management in R&D division under the implementation of PLM system. By knowing inside information of knowledge management in the R&D division of companies would make my research more practical and well-organized to give examples and facts to the future implementation of PLM system for Taiwan industries.

A teoria sobre Sistemas Nacionais de Inovação (SNI) evoluiu significativamente e tem auxiliado no diagnóstico de inovação em diferentes países. Ela tem sido criticada, porém, pela ausência de conceitos, instrumentos e ações práticas que permitam atuar no aprimoramento contínuo desses sistemas. No Brasil, por exemplo, análises do SNI indicam entraves como dispersão de recursos, fraquezas no sistema educacional e baixo investimento em P&D, mas não indicam caminhos concretos para se estimular mudanças nos atores do sistema. Este trabalho descreve uma experiência de indução da melhoria no SNI brasileiro, combinando a teoria de SNI com conceitos clássicos de Sistemas de Gestão Normalizados. Propõe-se um modelo de gestão que serve de orientação para Instituições de Pesquisa Científica e Tecnológica, pertencentes a um SNI, e que atuam como parte importante do processo de transferência dos produtos para os consumidores da tecnologia. A hipótese é que o padrão possa induzir a melhoria nessas instituições e gerar melhorias no sistema como um todo. A proposição do modelo foi realizada a partir de uma pesquisa-ação e um método etnográfico, utilizado para captar a percepção de especialistas da área. A partir dessa experiência, discutem-se entraves e especificidades para um Sistema de Gestão Normalizado voltado para a melhoria de Sistemas Nacionais de Inovação. Os resultados indicam a viabilidade da proposta, demonstrando que um padrão de sistema de gestão para inovação tem potencial para: a) sensibilizar e orientar atores do SNI para objetivos comuns em prol da cooperação no desenvolvimento de tecnologias; b) indicar mecanismos e ações que podem ser tomadas por estes atores; c) estimular o desenvolvimento de capacidades e habilidades que facilitem a cooperação entre empresas nas instituições que compõem o SNI. / The theory of National Innovation Systems (NIS) has evolved significantly and has aided the diagnosis for innovation in different countries. The NIS theory has, however, been criticized by lack of concepts, tools and practices that allow actions in ongoing improvement of these systems. In Brazil, for example, analysis indicate barriers related to dispersion of resources, weaknesses in the educational system and low investment in R&D, but dont indicate concrete ways to stimulate changes on the players of the system. This paper presents an experience for the improvement in the Brazilian NIS, combining NIS theory with classical concepts of Standardized Management Systems. It is proposed a management framework that provides a guidance for institutions of Scientific and Technological Research belonging to a NIS, playing an important role on the technology transfer process. The hypothesis is that the standard induces improvements to the R&D institutions and therefore to the whole system. The proposed framework has been developed from an action research and ethnographic methods in order to capture the perceptions of specialists. From this experience, it is discussed the main barriers and specificities of the development of a Standardized Management System oriented to the improvement of National Innovation Systems. The results indicate the feasibility of the proposal, showing that a management system standard for innovation can: a) sensitize and guide NIS actors to promote common goals to cooperate in developing technologies; b) indicate mechanisms and actions that can be applied by these actors; c) encourage the development of skills and abilities that facilitate cooperation between companies in the institutions comprising the NIS.

O consenso entre os organismos internacionais de cooperação para o comércio e para o desenvolvimento econômico está em reconhecer na capacidade de inovar a principal fonte para a promoção da produtividade nas organizações. Parte do esforço brasileiro de construção e desenvolvimento de um sistema nacional de inovação constituiu-se na criação de programas de incentivos fiscais, como forma de fazer avançar os investimentos em Pesquisa, Desenvolvimento & Inovação - P&D&I, provocando o setor privado a participar mais intensamente do processo de financiamento do desenvolvimento tecnológico. Uma década após a implementação do principal programa de incentivo fiscal à inovação no Brasil (Lei nº 11.196/05), é mister verificar se tais incentivos foram capazes de atingir os seus objetivos. A presente tese visa a avaliar: (i) qual a repercussão sobre os dispêndios com P&D&I da opção pela utilização dos incentivos fiscais concedidos pela Lei do Bem e (ii) quanto da renúncia fiscal, ou seja, dos créditos recebidos pelas empresas participantes deste programa, retornou em termos de investimentos em P&D&I ao longo do tempo. A metodologia empregada, propõe a estimação de um modelo empírico para os dispêndios em P&D&I, em que estes são explicados ora pela opção da empresa por utilizar os incentivos fiscais da Lei do Bem ora pela renúncia fiscal decorrente da utilização do mesmo programa, além de um conjunto de variáveis de controle associado às restrições de financiamento. Os testes estatísticos foram conduzidos para o agregado das companhias de capital aberto, registradas na BM&FBOVESPA em 2013, relativamente a seus desempenhos no período de 2008 a 2013. Os resultados, para dados em painel dinâmico, foram obtidos a partir do modelo GMM-System e apontam que a decisão de utilizar os incentivos fiscais da Lei do Bem está associada a um aumento nos dispêndios com P&D&I, ao longo do tempo. Assim sendo, para cada ponto percentual de aumento na propensão das companhias em optar pelo uso da Lei do Bem espera-se de 0,65 a 0,85 pontos percentuais de aumento em seus dispêndios com P&D&I. Por outro lado, o aumento de um ponto percentual na renúncia fiscal gera uma expectativa de aumento nos dispêndios com P&D&I das companhias, que pode variar de 0,26 a 0,40 pontos percentuais, ao longo do tempo / The consensus among international cooperation agencies for trade and economic development lies in recognizing in the ability to innovate the main source for promoting productivity in organizations. The Brazilian effort of construction and development of a national innovation system constituted the creation of tax incentive programs as a way to advance investments in Research, Development & Innovation - R&D&I, causing the private sector to participate more intensely financing process of technological development. A decade after the implementation of major tax incentive program for innovation in Brazil (Law nº. 11.196/05), it is necessary to verify that such incentives were able to achieve their goals. The present thesis aims at evaluating: (i) the impact on R&D&I expenditures of the option to use the tax incentives granted by the \"Lei do Bem\" and (ii) how much of tax waiver, that is to say, of the credits received by companies participating in this program, has returned in terms of R&D&I investments over time. The methodology to be used proposes the estimation of an empirical model for R&D&I expenditure, which are explained either by the company\'s option to use tax incentives of the \"Lei do Bem\" or by tax credits obtained due to the use of tax incentives program, in addition to a set of control variables associated with financing constraints. The statistical tests were conducted to the group of publicly traded companies listed on the BM & FBOVESPA in 2013, for their performances in the period 2008 to 2013. The results for the dynamic panel data were obtained from the GMM-System model and indicate that the decision to use the \"Lei do Bem\" tax incentives is associated with an increase in R&D&I expenditures over time. So that for each percentage point of increase in the propensity of companies to opt for the use of the \"Lei do Bem\", 0.65 to 0.85 percentage points of increase in R&D&I expenditures is expected. On the other hand, the increase of one percentage point in the tax waiver generates an expectation of increase in the R&D&I expenses of the companies, which can vary from 0.26 to 0.40 percentage points, over time
