This dissertation investigates the structure of incentive contracts in which adverse selection problems are more severe. Specifically, I examine the moderating effect of R&D intensity on the relative weights placed on signals of ability and on performance measures in executive compensation. Furthermore, I also investigate the determinants on the compensation of university presidents. I find that that more weight is placed on signals of ability in R&D intensive firms and less weight is placed on performance measures. I find that R&D intensive firms pay more to executives with technical work experience and/or relevant educational degrees. Additionally, in the context of university presidents, the positive association between organizational complexity and executive compensation is driven by the role of managerial ability rather than by effort. This result also suggests that considering measures of organizational complexity (such as firm size and diversification) as control variables in empirical studies of executive compensation is the appropriate means by which to account for the impact of organizational complexity. / Business Administration/Accounting

Yes / Technologies can help strengthen the resilience of our economy against existential climate-risks. We investigate climate change adaptation technologies (CCATs) in US patents to understand (1) historical patterns and possible drivers of innovation; (2) scientific and technological requirements to develop and use CCATs; and (3) CCATs’ potential technological synergies with mitigation. First, in contrast to mitigation, innovation in CCATs only slowly takes off, indicating a relatively low awareness of investors for solutions to cope with climate risks. We discuss how historical trends in environmental regulation, energy prices, and public support may have contributed to patenting in CCATs. Second, CCATs form two main clusters: science-intensive ones in agriculture, health, and monitoring technologies; and engineering-intensive ones in coastal, water, and infrastructure technologies. Analyses of technology-specific scientific and technological knowledge bases inform directions for how to facilitate advancement, transfer and use of CCATs. Lastly, CCATs show strong technological complementarities with mitigation as more than 25% of CCATs bear mitigation benefits. While not judging about the complementarity of mitigation and adaptation in general, our results suggest how policymakers can harness these technological synergies to achieve both goals simultaneously.

知識經濟時代與全球化潮流下，創新是廠商提升自我競爭力的重要途徑。創新乃原始概念到將知識商業化的一連串過程，而過去探討廠商創新的研究取向多元，研究觀點則以經濟地理學、企業管理學為主，綜合相關研究，大致可將影響廠商創新的因素歸類為三大面向：廠商內部屬性、對外網絡連結關係、廠商所處地區的環境條件。其中，創新氛圍乃是特定地區的行動者透過偕同作用及集體學習過程所產生的社會關係，提升了地區的創新能力，同時提供有利於廠商創新的環境條件，是近來區域發展的重要議題。本研究即綜合上述三大面向因素來探討廠商創新活動(研發投入與研發合作)與創新成效之影響因素。 創新氛圍理論從早期”某種東西之地方化”的探討，演變到後期關注於地方生產系統的運作是受到地區創新氛圍的影響所致；其中，創新氛圍量化指標的缺乏、探討領域的侷限，乃是本研究所要突破之處。本研究以工業區分佈情形、自然與人文界線、通勤圈範圍等原則，先將台灣地區分為46個地區分析單元，再參酌地方生產系統概念，以兩個指標：LQ大於1與製造業就業員工數大於50000人，篩選出26個地區作為研究範圍，最後以科技與傳統產業LQ大於1指標，區別出9個科技產業群聚地區、17個傳統產業群聚地區，藉以比較不同產業領域、地區發展程度不同之創新氛圍。準此，本研究以8個創新氛圍的相關指標，經過因素分析後萃取出2個創新氛圍因素：「創新綜效」、「創新成效」；藉此將台灣46個地區劃分為4種創新氛圍類型：創新氛圍、有創新無氛圍、有氛圍與創新、無創新無氛圍。 於廠商創新活動與成效實證分析方面，本研究採取兩個階段進行，分別皆以三個面向因素(廠商內部屬性、研發合作、地區創新氛圍)的影響因素來探討廠商創新活動與成效之差異。針對創新氛圍方面，於第一階段以不同產業群聚地區的虛擬變數作為隱含地區創新氛圍的概念，測試其對廠商創新活動與成效的影響，第二階段則以地區創新氛圍因素(創新綜效、創新成效)進行科技與傳統產業群聚地區的廠商創新成效之測試。整體研究結果顯示，科技產業群聚地區的廠商傾向自身的研發投入，而傳統產業群聚地區的廠商則多以研發合作居多，但科技產業群聚地區的廠商創新成效較佳；地區創新氛圍確實對於廠商的創新活動與成效有顯著的影響，尤其對於科技產業群聚地區的廠商創新成效更有顯著的貢獻；而研發合作對於廠商創新成效的影響則不如預期。因此，從基礎產業發展環境、知識設施的聚集、地區網絡的建構等方面，來促使各地區創新氛圍之形塑，將有利於地區廠商的創新，特別應加強傳統產業群聚地區的創新氛圍；此外，提倡廠商強化內部基本體質亦是促進廠商創新效率之關鍵所在。 / Under the wind of the knowledge-based economics and globalization, innovation is an important way for firms to increase their own competitiveness. Innovation is the process from original concept to business. The past researches on firm innovation branch widely, most focus on economic geography and corporation management. From those related researches, we can simplify the elements which can influence the innovation of the firm into three: firms’ inner attributes, relation of the connection to outside network, and the environment of the area which firms located. Innovation milieu is the social relationship which actors in the area could make it happen through interactions and group learning, which can advance the area’s innovation ability, and give the good environment condition for firms to innovate. Innovative milieu is the important issue in the present regional development researches, this research will integrate the three elements to discuss the influence on firms innovation activities and innovation success. The theory of the innovative milieu have transformed from discussion of “the localization of something” to focus on the relation of the work of the regional production system and the local innovative milieu. But, the lack of the quantification indicator, and the territory of the research field still need to break through, and is the focus of this research. This research divide Taiwan into 46 analysis area unit, then bring into the concept of the local production system, use two indicators to choose 26 elements as the scope of the research, and farther define 26 analysis area unit into 9 technology industry cluster area, and 17 traditional industry cluster area, to compare the differences of the industry field and the level of the development of the innovation milieu. This research take 8 innovative milieu related indexes, and compress into 2 indexes: “innovation synergy” and “innovation success” through the content analysis; this research use these two indexes to divide 46 areas of Taiwan into 4 types of innovation milieu: innovative milieu, no innovative milieu, innovation but without milieu, and milieu but without innovation. On the analysis of the firms’ innovation activities and the success, this research take two steps to discuss. At the first step, this research use the dummy variables of the different industry cluster area as the concept of the regional innovative milieu, to check the influence it could make on the firms innovation activities and the success; At the second step, this research use regional innovative milieu indexes to check the firms’ innovation success of the traditional and technology industry cluster area. The whole research shows that the firms of technology industry aggregation area are tend to invest on their own R&D, which the firms of traditional industry aggregation area often do their R&D by cooperating with others, and the innovation outcome of firms of the technology industry aggregation area is better. The regional innovative milieu has the conspicuous influence on the firms innovation activities and the success, especially to the technology industry cluster area, but the influence which the R&D cooperation could make on the innovation outcome is not good as expect. Thus, the making of the basic environment of the industry development, the aggregation of the knowledge facilities, and the build of the local network is the good impact for local firms to innovate, especially for the traditional industry aggregation area ones. At the same time, to reinforce the firms’ inner constitution is also the key to promote the firms innovation.

La thèse a pour but d’étudier la possibilité et la faisabilité économique de démarches de diversification des produits et d’amélioration des caractéristiques qualitatives des aliments par les entreprises, dans un contexte dans lequel ces modifications sont soumises à des contraintes techniques induisent des coûts non négligeables, non nécessairement valorisés par le marché. Dans ce cadre, nous cherchons à comprendre dans quelle mesure il est possible pour les autorités publiques d’intervenir pour inciter les entreprises à consentir des efforts suffisants (en termes d’investissement en amont) de façon à favoriser la mise en marché de produits conformes à la qualité voulue par la société. Nous avons appliqué ces perspectives de recherches à deux problématiques sociétales importantes et d’actualité, à savoir la coexistence des filières OGM et non OGM et la question de la santé et de la nutrition à travers l’enjeu de l’entrée de gammes de produits plus acceptables d’un point de vue nutritionnel (moins de sucre, de gras, …). Ces problématiques qui occupent les deux parties de la thèse sont élaborées en mobilisant des outils de la Théorie de l’Organisation Industrielle. Les résultats montrent que les choix spontanés de gammes de produits par les firmes ne sont pas toujours socialement satisfaisant, ce qui implique dans certaines conditions une intervention publique. Dans le cas de la coexistence OGM/non-OGM, le produit non-OGM peut ne pas avoir la caractéristique souhaitée en absence de régulation. Pour ce qui est des enjeux nutritionnels, les firmes présentes sur le marché n’offrent pas systématiquement des aliments favorables sur le plan de la santé en l’absence d’intervention publique. La thèse aboutit à la conclusion générale qu’il est souvent nécessaire de combiner plusieurs instruments publics. Dans le cas de la coexistence OGM/non-OGM, les pouvoirs publics peuvent gérer de manière efficace la coexistence en agissant simultanément sur le seuil d’étiquetage, les conditions de réalisation des tests et contrôles et le niveau de la pénalité. Dans le cas de la question nutritionnelle, l’intervention par le biais d’une subvention à la R&D présente certaines faiblesses telles que le risque d’instrumentalisation de la subvention par la firme ou induit des distorsions au détriment de la santé publique. Ceci suggère de combiner la subvention à la R&D avec un autre instrument tel que la taxation. / Our research aims at analyzing the economic feasibility of approaches for product diversification and quality characteristics improvement by firms, in a context where these modifications are subject to technical constraints that induce high costs not necessarily valued by the market. In this context, we try to understand how it is possible for public authorities to intervene in order to encourage firms to make sufficient efforts (in terms of upstream investment) and facilitate the marketing of products in response to the needs of society. We apply these research perspectives to two important issues, namely the GM/non-GM coexistence and the health and nutrition issue through the development of product lines which are more acceptable from a nutritional point of view (for example, less sugar, fat, salt…). These two research issues are developed by mobilizing the tools of the Theory of Industrial Organization. The results show that the spontaneous choice of product lines by firms is not always socially satisfactory, which implies that in certain conditions, public intervention is desirable. In the case of GM/non-GM coexistence, non-GM products may not have the desired characteristics in the absence of regulation. In terms of health issues, companies in the market do not offer high nutritional value foods in the absence of public intervention. Overall, this thesis concludes that it is often necessary to combine several public instruments. In the first study, we show that the public authorities can effectively manage the GM/non-GM coexistence by acting simultaneously through the labelling threshold definition, the quality tests and controls, and the level of the penalty cost in case of non compliance. In the second study, we show that an intervention through Research and Development (R&D) subsidies has some weaknesses such as the risk of manipulation of the grant by firms, or the possibility of triggering distortions to the detriment of public health. This suggests combining the R&D subsidies with another instrument such as taxation

Cette thèse présente trois chapitres qui mobilisent un cadre d’analyse évolutionniste et qui étudient empiriquement la relation « innovation-performance » à partir de données CIS. Nous souhaitons montrer que les sources de l’innovation et les méthodes d’appropriation varient en fonction des secteurs d’activité et des stratégies d’innovation des firmes. Dans un premier temps, nous décrivons les tendances de l’innovation à partir de quatre vagues d’enquêtes CIS (1994-2006) et nous analysons la persistance de l’innovation sur un échantillon de 431 firmes avec une régression logistique binaire. Nous montrons que la persistance de l’innovation est plus élevée pour les firmes qui innovent en produits car ces firmes sont contraintes d’investir de manière continue dans des projets d’innovation pour rester compétitives. Les firmes qui innovent en procédés sont moins persistantes car leur stratégie est plus orientée vers des ajustements de la qualité des produits ainsi que vers l’amélioration des processus de production. Les deux derniers essais explorent avec la méthode des doubles moindres carrés le lien innovation-performance économique sur un échantillon de 7 742 firmes portant sur la période 2002-2005. Nous expliquons que la source principale de l’innovation des firmes à « forte intensité scientifique » est la R&D, d’une part, et que les méthodes d’appropriation des rentes de l’innovation passent par l’acquisition d’actifs complémentaires (tels que l’utilisation combinée de titres de propriété intellectuelle et de secrets de fabrication), d’autre part. En revanche, les firmes dans les autres catégories (notamment celles à fortes économies d’échelle) fondent leurs avancées technologiques sur des sources externes de l’innovation telles que les concurrents, les fournisseurs et les utilisateurs avancés. De plus, ces firmes utilisent de manière plus importante des méthodes d’appropriation commerciale telles que les marques ou les stratégies marketing, car leurs produits sont moins exposés au risque d’imitation certes, mais aussi parce qu’elles sont sensibles aux changements de coûts. / This thesis is structured in three essays based on evolutionary theoretical grounds and provides empirical evidence from CIS. It aims at showing that the sources of innovation and the appropriation of innovation rents vary in function of firms’ activities and innovation strategies.In essay 1, we describe four waves of CIS, covering the period 1994-2006 and we study persistent innovation behavior with a discrete choice model on a data set of 431 firms. We find that innovation persistence is more important for product innovators because they need novel products to be more competitive and therefore enrich their base of knowledge continuously. By contrast, process innovators are less persistent because innovation strategy is less “market” oriented and intends to meet quality or production adjustments. The two last essays explore with the two stage least squares method how firms benefit economically from their innovations on a sample of 7 742 firms, on the period 2002-2005. We show that science-based firms rely more on R&D investments to develop their products and maintain their leads by acquiring complementary assets, i.e. they use mixed methods to appropriate the rents of innovation (the combined use IPRs and strategic methods for instance secrecy). By contrast, firms in other categories (for instance firms using cost-cutting strategies) draw more on external sources of knowledge coming either from suppliers or advanced users. Additionally, these firms use more extensively trademarks or non technological methods of appropriation (as marketing devices), because they are less exposed to potential imitation and because they are price sensitive.

Os projetos de pesquisa e desenvolvimento na CNEN são financiados pelos recursos diretos do orçamento da União e das Agências de Fomento como a FINEP e o CNPq. De um modo geral os gerentes de projetos acreditam que conseguem ter sucesso quando completam um projeto no prazo programado, no orçamento e nos requisitos previstos, que é comumente conhecido como “restrição tripla” ou “triângulo de ferro”. Entretanto, na revisão da literatura verificou-se outros critérios de avaliação do sucesso nos projetos, como os benefícios gerados à sociedade, o desenvolvimento das capacidades da equipe, as oportunidades futuras, novas tecnologias, entre outros. Diante dessa questão, buscando auxiliar o gestor na avaliação dessa tipologia de projetos, a pesquisa propôs um modelo com critérios e requisitos baseado na revisão da literatura e buscou através de um questionário medir os graus de importância e de utilização desses critérios junto aos especialistas da CNEN, que atuam diretamente na execução desses projetos. Os resultados revelaram que os critérios propostos no modelo possuem um grau de importância alto, com uma queda em relação à utilização, indicando que os critérios utilizados no modelo podem auxiliar os gestores na avaliação dessa tipologia de projeto. / Science and technology are directly related to the development of a country. The research and development projects at CNEN are financed by the direct resources of the budget of the Union and of the Development Agencies such as FINEP and CNPq. In general, project managers believe they can succeed when they complete a project within the programmed schedule, budget, and anticipated requirements, which is commonly known as a "triple constraint" or "iron triangle." However, in the review of the literature, other criteria for evaluation of success in projects, such as the benefits generated by society, the development of the team's capabilities, future opportunities, new technologies, among others, were verified. Faced with this question, seeking to assist the manager in the evaluation of this typology of projects, the research proposed a model with criteria and requirements based on the literature review and sought through a questionnaire to measure the degrees of importance and use of these criteria with the specialists of CNEN , Which act directly in the execution of these projects. The results showed that the criteria proposed in the model have a high degree of importance, with a decrease in relation to the use, indicating that the criteria used in the model can help managers in the evaluation of this type of project.

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。

本研究以區域創新系統觀點，分析在兩岸區位優勢差異下，影響台灣製造業廠商兩岸研發區位選擇及廠商研發網絡治理情形，強化既往研究未同時關注台商、兩岸地區及偏重個案研究的不足之處；經實證結果發現，區位優勢、研發部門類型、市場規模、政策條件、產業群聚、知識流通及研發經費投入等變數為台商兩岸研發區位佈點的影響變數，除了市場規模及市場型研發部門與研發區位選擇呈現負向關係外，其他皆與區位選擇呈現正向關係，顯示除因台灣市場規模太小造成台商選擇至對岸設立研發部門外，台灣在其他表現上皆較對岸具有吸引力，台灣仍具有不可忽視的區域創新能量，建議政府部門應在產業政策上有新作為，提供廠商各項研發所需要的協助，以吸引更多本土企業於台灣設立研發部門，以不斷累積及提升台灣的研發競爭力。 區域創新系統強調區域內行動者的網絡連結及互動，形塑該地區無可取代的區域特色，為彌補研發區位選擇的量化研究，無法表達出區域創新系統內廠商在地化網絡連結及互動的情況，本研究在研發網絡治理部分以華碩企業集團為研究對象，探討其如何運用本身及當地資源，建立在地化網絡及維持網絡關係運作等網絡治理議題，經研究結果發現，由於華碩企業集團具有豐富的研發經驗、高水準的研發人員及雄厚的資金，扮演在地化網絡主要行動者的角色，掌握與其他行動者（例如政府部門、研究機構、大專院校及其他廠商等）間關係建立的主導權，在研發技術的傳遞上係以公司內部的垂直組織網絡為主要傳遞路徑，與區域創新系統內各行動者的網絡關係及在地鑲嵌程度不強。 / With the viewpoint of regional innovation system, this paper analyzes the impacts of R&D locational choices and enterporises’ R&D network governance that manufacturing firms in Taiwan have under the differentiation of locational advantages between China and Taiwan as well as consolidates some points which are incompletely focused in the past on Taiwanese firms, two sides of Taiwan Strait, and overweighing case-studies. The empirical evidences bring that the impacts of variable to locational distribution of Taiwanese manufacturing firms across the strait are many: locational advantages, the types of R&D unit, the scales of market, policy conditions, industrial clusters, knowledge flows and R&D investment. Except for the negative correlations between the scale of market/type of R&D unit and R&D locational choices, the rest variables have the positive correlation with R&D locational choices, which means that, barring that the scale of market in Taiwan is so small that Taiwanese firms choose to institute R&D spots in China, other variables in Taiwan are more attractive than those in China; Taiwan possesses innegligible energy of regional creativity. The suggestion is that the government has to take new actions on industrial policy, providing the assistance to R&D that enterprises need, in order to attract more and more local enterprises to set up their R&D functions in Taiwan for accumulating and advancing Taiwan’s competitive power continuously. Regional innovation system emphasizes on actors’ network linkages and interactions within one region, shaping irreplaceable regional characteristics for that region in order to atone for the quantitative research of R&D locational choices which cannot express the situation of enterprises’ localized network linkages and interactions within regional innovation system. Taking ASUS as example, this research, in terms of network governance, confers how ASUS draws on own and local resources for network governance issues like establishing localized networks and maintaining the operation of network relations. After the analysis, it is found that, on account of ASUS with abundant R&D experiences, high-level R&D staffs and tremendous funds, ASUS plays the role as key actor in the localized network, controlling the predominant power established by relations between other actors (i.e. public sectors, research institutes, colleges/universities, other enterprises and so on). In terms of R&D technology transfer, vertical networks in the inner company as main transfer passage is less attached with every actor’s network relation and its local embeddedness within regional innovation system.

This thesis consists of five individual essays and an introductory chapter. The essays are all in the field of industrial dynamics and more specifically focus on firm entry and exit in Swedish industrial sectors. The essays mainly contribute to the empirical literature on entry and exit. In four of the five essays, panel data methods are used in the empirical investigation. The first essay presents the patterns of entry and exit in industrial sectors in Sweden and studies the importance of different determinants of entry and exit rates in industries. The second essay focuses on the relationship between entry and exit. The third essay has a regional perspective, focusing on regional determinants of entry and exit. It also investigates the importance of the differences in industry structure for differences in entry and exit rates across regions. The fourth chapter uses the theory of product life cycle to investigate how knowledge intensity differs in entering and exiting firms in different stages of the product life cycle. The fifth and last essay focuses on the importance of firm demography, in terms of firm size and age, for the decision to perform process R&D, product R&D or combine process with product R&D.
