Este trabalho está voltado para o estudo da relação entre tecnologia e dinâmica industrial. Para tanto, utiliza-se o conceito de regimes tecnológicos com enfoque nas barreiras tecnológicas à entrada em detrimento das condições de apropriabilidade. As barreiras tecnológicas à entrada são as características próprias ao conhecimento necessário para inovar que limitam o seu acesso por concorrentes potenciais, ou seja, fazem uma distinção clara entre a concorrência potencial e a concorrência efetiva. Desta forma, as características do conhecimento e do processo inovativo determinam e condicionam a estrutura de mercado e a dinâmica industrial. O conceito de regimes tecnológicos permite agrupar os setores cujas características do processo inovativo e de dinâmica industrial sejam semelhantes. A tipologia de regimes tecnológicos adotada foi elaborada por Marsili (2001), a partir de indicadores extraídos dos países desenvolvidos. Considerando que o processo inovativo difere significativamente entre países desenvolvidos e em desenvolvimento, o objetivo deste trabalho foi verificar se esta tipologia é adequada ao estudo da indústria brasileira. Para alcançar este objetivo, foram utilizados métodos da análise estatística multivariada e indicadores sobre tecnologia, inovação, estrutura de mercado e dinâmica industrial. Os testes empíricos realizados mostraram que a taxonomia de regimes tecnológicos não formou grupos setoriais significativamente distintos, de modo que fosse possível identificá-los. Além disso, a análise de clusters evidenciou, através de novos agrupamentos setoriais, que a indústria brasileira possui regimes tecnológicos que diferem dos definidos para os países desenvolvidos. Portanto, os resultados obtidos reforçam a importância de aprofundar a literatura sobre as características da mudança técnica nos países em desenvolvimento. / This work concerns the study of the relationship between technology and industrial dynamics. To assess this relationship, the concept of technological regimes, centered in the technological entry barriers instead of the apropriability conditions, is used. The technological entry barriers are the characteristics belonging to the knowledge necessary to innovate that limit the accesses to this knowledge from potential competitors, that is, they make a clear distinction between potential and effective competition. This way, the knowledge’s characteristics and the innovative process determine and condition the market structure and the industrial dynamics. The concept of technological regimes allows the grouping of the sectors whose characteristics of innovative process and industrial dynamics are similar. The typology of technological regimes adopted was elaborated by Marsili (2001), who used indicators extracted from developed countries. Considering that the innovative process differs significantly between developed and developing countries, the objective of this work was to verify if this typology is adjusted to the study of the Brazilian industry. To reach this objective, methods of multivariate statistical analysis and indicators of technology, innovation, market structure and industrial dynamics were used. The empirical tests carried through showed that the taxonomy of technological regimes didn’t form significantly distinct sectorial groups, so that it could be possible to identify them. Moreover, the analysis of clusters evidenced, through new sectorial clusters, that the Brazilian industry has technological regimes that differs from the ones defined to the developed countries. Therefore, the obtained results strengthen the importance of deepening the literature on the characteristics of technical change in developing countries.

Is a new proposed point of view, without competition between economy and the environment (as the conventional theory does). The ecology should be in the competitive strategies of the firm. Through computational simulation method was investigated the effectiveness of three types of policies, all different about their restrictiveness degree. Such policies are: an ecological tribute, a subsidy to green R&D, and a program for environmental education that means, in the market, a consumer‟s preference for ecology. Were simulated nine types of policies combinations, with different values for the parameters, with the objective to test the economics variables‟ sensibility. Hence, the main purpose is to find the best policy for the environment and its consequences for the industrial dynamic. The most important conclusion is that the success of an environmental policy depends on its restriction, as Porter has supposed / Este trabalho traz uma abordagem evolucionária para a discussão da problemática ambiental, propondo uma visão não concorrente (como realizada pela teoria convencional) entre economia e meio ambiente. Sugere-se a integração da variável ambiental como estratégia competitiva das firmas. Através do método de simulação computacional verificaram-se a eficácia de três tipos de políticas, todas diferentes quanto ao seu grau de restrição, quais sejam: um imposto ambiental, um subsídio à P&D verde , e um programa de educação ambiental que se traduz no mercado como uma preferência do consumidor à um produto ecológico. Foram simulados nove tipos de combinações derivados dessas políticas, com diferentes valores de parâmetros, a fim de se testar a sensibilidade das variáveis econômicas à estas políticas. Assim, objetivou-se averiguar qual tipo de política gera o melhor resultado ambiental, e suas conseqüências para a dinâmica industrial. Como principal conclusão, encontrou-se que o resultado da política ambiental depende do seu grau de restrição, corroborando com o que Porter chama de boa regulamentação .

The evolution within an economic context is the result of the adaptation process of the firms the industrial structure of the sector, these ' adaptations ' correspond to the result of an intense action of search and selection, where the economic imbalance corroborates the existence of this process. Within the notion of technological paradigm established by Dosi (1988), the firm chooses the best alternative, procedures, criteria and rules established ex ante, their actions are derived from the conditions of uncertainty, defined by the basis of information obtained in addition to the accumulation of knowledge - formal and informal - the capacity to acquire technologies and viewing opportunities. Nelson and Winter (1982) show that technical progress is endogenous in nature, this progress can be built from the establishment of patterns of response actions, or rather routines. These routines can be divided into long and short term. As the dynamics of technical progress is endogenous technical change is coming this procedure adaptive routines, from the same are established technological trajectories, which differ from industry to industry, as the dominant technology in an industry is not necessarily put to other. In this context, this dissertation seeks to demonstrate the existence of such a process applied to the sugarcane sector, after it has undergone sweeping changes since the merger and acquisition through foreign capital investment companies or other sectors, corroborating the concentration of productive activity the hands of some economic groups thus are identified characteristics of both technology standards Schumpeter Mark I and Schumpeter Mark II, many firms are in this industry, however, the process of creative destruction promoted by the accumulation of knowledge is intense. The aim was to analyze the industrial dynamics present in the sugarcane industry through models, aiming at a better understanding about the transformation started with Proálcool and heated with deregulation and lastly the impact of the international economic crisis in 2008. For this purpose, we used data collected from the Procana, ANP (National Agency of Petroleum, Natural Gas and Biofuels) and reports production cost PECEGE (Continuing Education Program in Economics and Business Management) linked to ESALQ. For the analysis, we used statistical and econometric models (Factor Analysis, Multiple Regression Analysis and Analysis of Panel Data). How relevant results it is found that: i) the changes occurred may last for a few more years, ii) the endogenous variables of each plants is that they are influencing the intense transformation, since the applied technologies has originated in response patterns, iii) routinization has shown strong impact on industry structure resulting from the process of search and selection, plants are failing to adapt are declaring bankruptcy or being acquired by larger iv) as a result of creative destruction, economic groups are influencing the concentration of industry, this action is a result of the accumulation of capital and better adaptation v) the concentration of capital is taking place in the South Central region of the country, approximately within the ' polygon ' development, highlighted by Breitbach (2004) and expanding around this region. / A evolução, dentro de um contexto econômico é resultante do processo de adaptação das firmas a estrutura industrial do setor, essas ‘adaptações’ correspondem ao resultado de uma intensa ação de busca e seleção, onde o desequilíbrio econômico corrobora com a existência desse processo. Dentro da noção de paradigma tecnológico, estabelecido por Dosi (1988), a firma escolhe as melhores alternativas, procedimentos, critérios e regras estabelecidas ex-ante, suas ações derivam das condições de incerteza, definidas pela base de informações obtidas, além da acumulação de conhecimentos – formais e informais –, da capacidade de apropriação de tecnologias e da visualização de oportunidades. Nelson e Winter (1982) evidenciam que o progresso técnico é de natureza endógena, esse progresso pode ser construído a partir do estabelecimento de padrões de ações de respostas, ou melhor, rotinas. Essas podem ser divididas em rotinas de longo e curto prazo. Como a dinâmica do progresso técnico é endógena, a mudança técnica é oriunda desse procedimento de rotinas adaptativas, a partir do mesmo são estabelecidas as trajetórias tecnológicas, as quais diferem de indústria para indústria, pois a tecnologia dominada em um setor não necessariamente está posta para outro. Diante desse contexto, essa dissertação busca evidenciar a existência de tal processo aplicado ao setor canavieiro, afinal este tem passado por intensas transformações, desde fusão e aquisição até o investimento de capital estrangeiro ou de empresas de outros setores, corroborando para a concentração da atividade produtiva nas mãos de alguns grupos econômicos, dessa forma são identificadas características de ambos os padrões tecnológicos de Schumpeter Mark I e Schumpeter Mark II, diversas firmas estão presente no setor, entretanto, o processo de destruição criadora promovido pela acumulação de conhecimento é intenso. O objetivo foi analisar a dinâmica industrial presente no setor canavieiro através de modelos, visando uma melhor compreensão a respeito das transformações iniciadas com o Proálcool e acaloradas com a desregulamentação e por último com o impacto da crise econômica internacional de 2008. Para tanto, foram utilizados dados colhidos junto ao Procana, ANP (Agência Nacional do Petróleo, Gás Natural e Biocombustíveis) e relatórios de custo de produção do PECEGE (Programa de Educação Continuada em Economia e Gestão de Empresas) vinculado a ESALQ. Para a análise, foram utilizados modelos estatístico e econométricos (Análise Fatorial, Análise de Regressão Múltipla e Análise de Dados em Painel). Como resultados relevantes verifica-se que: i) as transformações ocorridas poderão perdurar por mais alguns anos; ii) as variáveis endógenas das usinas estão influenciando a intensa transformação, visto que as tecnologias aplicadas apresentam origem em seus padrões de resposta; iii) a rotinização tem apresentado forte impacto na estrutura do setor, resultante do processo de busca e seleção, as usinas que não estão conseguindo adaptar-se estão declarando falência ou sendo adquiridas por outras maiores; iv) como resultado da destruição criadora, grupos econômicos passam a influenciar na concentração do setor, essa ação é resultado da acumulação de capital e melhor adaptação v) a concentração do capital está ocorrendo na região Centro-Sul do país, aproximadamente dentro do ‘polígono de desenvolvimento’, destacado por Breitbach (2004) e se expandindo ao redor dessa região.

Concept populaire au sein de l’école française d’économie industrielle ainsi que dans le domaine des politiques industrielles de la période d’après Seconde guerre mondiale au début des années 1980s, la filière fait l’objet d’une résurgence dans la période actuelle. Ce retour s’est effectué, dans le langage et l’action politique, à la faveur des Etats Généraux de l’Industrie (EGI) de 2009. Toutefois, le flou qui entourait la notion de filière et qui avait conduit en partie à son abandon n’a pas été éclairci. Ce travail de thèse a pour objectif de proposer une vision de la notion de filière permettant d’en saisir les dynamiques dans le contexte économique actuel caractérisé par une internationalisation des activités productives. Outre cette dimension conceptuelle, les travaux qui vont suivre proposeront des méthodes de description et d’analyse de filière. Ces méthodes seront appliquées au domaine des oléo-protéagineux. La première partie de la thèse reviendra sur les acceptions et méthodes statistiques classiquement associées au concept de filière. La seconde partie quant à elle, en se basant sur les travaux de méso-économie politique, proposera une conception et une méthode méso-systémiques de la filière permettant d’en saisir les dynamiques. / The popular concept, within the French school of industrial economics and of industrial policies, filiere from post-World War II to the early 1980s, is experiencing a resurgence in the current period. This revival was made, in language and political action, thanks to the 2009 Etats Generaux de l'Industrie (EGI). However, the vagueness surrounding the concept of filiere, which has led in part to its abandonment, has not been clarified. The objective of this thesis is to propose a vision of the notion of filiere that will make it possible to understand its dynamics in the current economic context characterized by an internationalization of productive activities. In addition to this conceptual dimension, the work that follows will propose methods for describing and analysing filiere. These methods will be applied to the field of oleo-proteaginous. The first part of the thesis will return to the statistical meanings and methods traditionally associated with the concept of filiere. The second part, based on meso-economical politics, will propose a meso-systemic conception and method of filiere in order to understand its dynamic.

Currently, more than half of all Swedish single-family houses have an installed heat pump and more heat is supplied by heat pumps in Sweden than in any other nation. Despite the enormous impact of heat pumps on the Swedish energy system, the transition towards their use has gone relatively unnoticed. Hence the title of this thesis, ‘A silent revolution’. This thesis provides an in-depth study of the Swedish transition towards heat pumps and how Swedish industries contributed to it. It approaches the topic from the perspective of value networks and ‘coopetition’, combined with the concept of complementarities. This approach has been inspired by the work of Verna Allee (2009) and Erik Dahmén (1991). In this thesis, value networks are networks of actors surrounding a specific business model, coopetition is used to describe the relationships between actors (as both competitive and cooperative), and the concept of complementarities is used to analyze the dynamics between synergistic elements and value networks in Sweden’s heat pump sector and energy system. Based on this approach, the thesis explains how a durable web of relations and interdependencies between complementarities has developed within the heat pump sector and the energy system in Sweden, and between the two, during the country’s transition to widespread use of heat pumps. Interest in heat pumps arose in Sweden and other parts of Europe during the 1970s. The Swedish energy system had been caught between international oil crises and national political mobilisation against nuclear power expansion. In this period of negative transformation pressure, the heat pump appeared as a promising alternative that could mitigate the use of oil and electricity for heating. In the 1970s, an early Swedish heat pump industry formed together with a growing heat pump market. A large number of diverse actors became involved in the Swedish heat pump sector, and the intense coopetition dynamics relating to heat pumps following the 1970s oil crisis contributed to durable connections between complementarities during the early stages of the transition. The 1980s saw a rapid expansion of large heat pumps in Swedish district heating facilities. In the mid-1980s, however, oil prices dropped back to their previous low levels. This change, combined with other factors, such as lifted subsidies and higher interest rates, created a crisis for Swedish heat pump industry. The industry underwent a 10-year period of low sales of small heat pumps and the market for large heat pumps died out and never returned. Nevertheless, several connections between heat pump–related complementarities remained in Sweden after the mid-1980s. In conjunction with value network reconfigurations, changes in company ownerships and governmental industry support, these complementarities helped the Swedish heat pump sector to maintain both production and service capacity. Due to developments that took place largely outside the heat pump manufacturing sector, by the mid-1990s it became possible for the struggling Swedish industry to offer more reliable and standardised heat pumps to the Swedish home heating market. During the years after 1995, the Swedish heat pump market grew to become the biggest in Europe. The industry’s early development and growth gave Swedish companies a comparative advantage over its European competitors, with the result that the manufacturing of heat pumps remained concentrated to Swedish-based manufacturing facilities even after the Swedish heat pump industry became internationalised after 2005. As of 2015, Sweden had the greatest amount of heat production from heat pumps per capita of any European nation, and many heat pump markets in other European countries are 10 to 20 years behind the Swedish market in development. This thesis shows how the Swedish heat pump industry has co-evolved with the market and how developments in the industry contributed towards causing the transition to heat pumps to occur so early in Sweden relative to other European markets. It also shows that coopetition dynamics in a socio-technical transition change with the emergence and characteristics of structural tensions between complementarities, which has implications for the strategic management of external relations and partnerships during socio-technical transitions. It further argues that the combination of the value network, coopetition, and complementarity concepts can be conceptualised for descriptive and exploratory studies on the role of firms and industries in socio-technical transitions, thereby offering a complement to existing dominant frameworks in the area of transition studies. / För närvarande har mer än hälften av alla svenska husägare en installerad värmepump. Värmepumpar levererar mer värme per capita i Sverige än i något annat land. Men trots värmepumparnas stora genomslag i det svenska energisystemet har övergången från olja och el till värmepumpar gått relativt obemärkt förbi. Därav titeln på denna avhandling, ”en tyst revolution”. Denna avhandling ger en djupgående beskrivning av den svenska övergången från olja och el till värmepumpar och av hur den svenska industrin bidragit till utvecklingen inom det svenska värmepumps- området. Forskningsansatsen i denna avhandling bygger på ett värdenätverks- och ’coopetition’-perspektiv i kombination med användningen av det dynamiska analytiska begreppet komplementaritet. Denna ansats är inspirerad av Verna Allees (2009) och Erik Dahméns (1991) arbeten. Begreppet värdenätverk används i denna avhandling för att beskriva det nätverk av aktörer som omger en specifik affärsmodell, begreppet ’coopetition’ används för att beskriva relationerna mellan aktörer (som både konkurrerande och samarbetande) och begreppet komplementaritet används för att analysera dynamiken mellan synergistiska delar och värdenätverk i den svenska värmepumpsektorn och det svenska energisystemet. Genom detta tillvägagångssätt beskrivs hur ett hållbart nät av relationer och ömsesidiga beroenden mellan komplementariteter har utvecklats, dels inom själva värmepumps- sektorn, dels mellan värmepumpssektorn och energisystemet i Sverige, under den svenska övergången mot ökad användning av värmepumpar. Intresset för värmepumpar steg i både Europa och Sverige under 1970- talet. Det svenska energisystemet var under tryck från både internationella oljekriser och nationell politisk mobilisering mot svensk kärnkrafts-utbyggnad. Under denna period när det svenska energisystemet var under negativt omvandlingstryck framstod värmepumpen som ett lovande alternativ som skulle kunna minska användningen av både olja och el för uppvärmning i Sverige. På 1970- talet bildades en svensk värmepumpindustri i samband med en växande värmepumpsmarknad. Ett stort antal aktörer av olika typer engagerade sig i den växande svenska värmepumpsektorn under denna period. Den intensiva samarbetsdynamiken kring värmepumpar som följde oljekrisen från 1970-talet bidrog till bildandet av varaktiga kopplingar mellan komplementariteter under denna tidiga fas i värmepumpsövergången. Under tidigt 1980-tal steg den relativa försäljningen av villavärmepumpar kraftigt och under mitten av 1980- talet skedde en ännu kraftigare utveckling av stora värmepumpar i svenska fjärrvärmeanläggningar. Men i mitten av 1980-talet sjönk oljepriset tillbaka till sina tidigare låga nivåer. I kombination med andra faktorer, så som slopade subventioner och höjd ränta, uppstod en kris för värmepumpar i Sverige. Den följande 10-års perioden karakteriserades av låg försäljning av små värmepumpar. Marknaden för stora värmepumpar försvann helt och skulle aldrig återkomma. Men flera kopplingar mellan värmepumpsrelaterade komplementarier kvarstod i Sverige även efter mitten av 1980-talet. I kombination med värdenätverkskonfigurationer, förändringar i företagsägande och statligt stöd till industrin, bidrog dessa hållbara kopplingar mellan komplementarier till att upprätthålla både produktion och servicefunktioner inom den svenska värmepumpsektorn. På grund av den tekniska utvecklingen, som i stor utsträckning skedde utanför tillverkningssektorn, blev det i mitten av 1990-talet möjligt för den kämpande svenska värmepumpsindustrin att erbjuda mer pålitliga och standardiserade villavärmepumpar till den svenska hemmamarknaden. Under åren efter 1995 växte den svenska värmepumpmarknaden till att bli den största i Europa. Den svenska marknadens och industrins utveckling och tillväxt gav svenska företag en relativ fördel gentemot sina eftersläntrande europeiska konkurrenter, med följden att tillverkningen av värmepumpar förblev koncentrerad till svenska anläggningar även efter det att en stor del av svensk värmepumpsindustri blivit uppköpt av utländska företag efter 2005. År 2015 var Sverige fortfarande det land med mest värme från värmepumpar per capita i Europa och den svenska utvecklingen var 10- 20 år före andra europeiska värmepumpmarknader. Denna avhandling beskriver samutvecklingen mellan den svenska värmepumpssektorn och det svenska energisystemet och hur den industriella utvecklingen bidragit till att den svenska övergången till värmepumpar var relativt tidig i jämförelse med andra europeiska marknader. Avhandlingen visar också att aktörsdynamiken i en socio- teknisk övergång förändras med uppkomsten av strukturella spänningar mellan komplementariteter, vilket har betydelse för hur externa relationer och partnerskap hanteras av företag och organisationer som genomgår omfattande socio-tekniska övergångar. Vidare argumenteras för att begreppen värdenätverk, coopetition, och komplementariteter kan kombineras i ett konceptuellt ramverk för att beskriva och analysera företags och industriers roller i omfattande socio-tekniska övergångar och därigenom komplettera nuvarande dominerande konceptuella ramverk för studier av omfattande socio-tekniska övergångar. / <p>QC 20171023</p>
