Bakgrund och problemdiskussion:Corporate social responsibility är ett ansvarsåtagande som expanderat i samhället de senaste årtiondena. Samhället präglas idag av en större medvetenhet och ställer allt högre krav på att företag ska agera hållbart i sin verksamhet. Modeindustin har fått utstå stor kritik i media men även i andra informationskanaler. Kritiken speglar framförallt deras externa leverantörers hållbarhetsåtagande, som företagen importerar sina produkter ifrån. Leverantörerna är framförallt etablerade i utvecklingsländer och har tidigare använt sig av barnarbete, haft bristfälliga anställningsvillkor och samtidigt haft negativ påverkan på miljön. Detta är några av anledningarna till att modeföretagen ställs inför allt hårdare krav. Det är därför av stor vikt att de synliggör för samhället sitt engagemang i CSR och därigenom uppfyller kraven som ställs på dem. Hållbarhetsrapportering har därför blivit ett av de mest betydelsefulla tillvägagångssätten inom modeindustrin som ett bevis för att de uppfyller CSR-åtagandet. Syfte:Syftet med uppsatsen är att ta reda på ifall modeindustrin implementerar CSR i sin verksamhet för att överleva på marknaden eller för att generera konkurrensfördelar och högre ekonomisk vinst. Metod:Undersökningen genomfördes på samtliga börsnoterade modeföretag i Sverige. Vi utförde en innehållsanalys där samtliga modeföretagens hållbarhetsrapporter analyserades och granskades för att få information om deras CSR-engagemang. Slutsats:Modeindustrin utformar generellt sätt CSR-rapporter av symboliska skäl. Företagen utför med andra ord hållbarhetsaktiviteter för att överleva på marknaden och försäkra sig om en långsiktig framtid. Hållbarhetsansvarstagande är något som framförallt deras nyckelintressenter; kunderna kräver,vilket företagen måste beakta för att inte försämra sitt rykte och kritiseras i media. / Background and problem discussion:The focus on corporate social responsibility has expanded in the society in the past few decades. Our society is characterized by an improved awareness of the topic and it imposes increased demands on companies in terms of being sustainably responsible in their business activities. The fashion industry has received a lot of criticism in the media and other information channels. Primarily, the criticism concerns the nature of activities, whether sustainably responsible or not, of third party suppliers with whom the fashion industry companies cooperate. Third-party suppliers are mostly located in developing countries and have previously been involved in the employment of child labor, providing inadequate employment conditions as well as having a negative impact on the environment. This is one of the factors leading to fashion companies now facing stricter requirements. Thus, it is of crucial importance that companies in the fashion industry engage in CSR activities and satisfy expectations on them. Therefore, the sustainability reporting system is one of the most prominent approaches in the fashion industry, offering a way to prove and communicate their CSR activities. Purpose:The purpose of this essay is to investigate whether the fashion industry implements CSR in their activities to either survive as a competitor in the market, or for the purpose of generating competitive advantage and higher financial profit. Method: All publicly listed fashion industry companies in Sweden were included in this research. We conducted a content analysis where all fashion industry companies' sustainability reports were analyzed and reviewed to generate information about their CSR engagement. Conclusion: he fashion industry delivers CSR reports for symbolic purposes. The fashion industry companies implement sustainably responsible activities in order to survive as a competitor in the market and in order to ensure a long-term future. Sustainable responsibility is of importance to the key stakeholders, i.e. the customers, of fashion industry companies, and therefore a topic that must be on the agenda of these companies in order to avoid damage to their reputation and criticism in media.

Bakgrund och problem: Den allt mer digitaliserade världen har skapat andra förutsättningar att bedriva verksamhet på. Ett skifte har identifierats där betydelsen av värde och hur värde skapas har förändrats. Interaktionen mellan företaget och kunden har blivit platsen där värde urskiljs och uppstår. Den traditionella företagsmodellen har utmanats i en större utsträckning av en affärsmodell som är baserad på prenumerationer istället för engångsköp av en produkt. En prenumerationsbaserad affärsmodell innebär att företagen har förändrat sitt synsätt på kunderna och förmågan av att upprätta långsiktiga relationer med kunderna är av stor betydelse för att uppnå framgång. Samtidigt som en mer föränderlig omgivning kräver ett externt fokus för att företagen ska kunna vara agila och ha möjlighet till att hantera förändringar på marknaden. Genom ett större fokus på kunderna, omgivningen och framtiden krävs det en ny typ av ekonomistyrning. Då den traditionella ekonomistyrningen inte är anpassad efter dagens företag och deras förutsättningar vilket gör den otillräcklig. Syfte: Syftet med studien är att beskriva och förklara vilka situationsfaktorer som är utmärkande för företag som har en prenumerationsbaserad affärsmodell samt hur detta påverkar dessa företags värdeerbjudande och ekonomistyrning. Studien syftar även till att företag inom prenumerationsekonomin kan dra lärdom av den kunskap som studien tillför. Metod: Studiens tillvägagångssätt har varit av kvalitativ karaktär där forskningsdesignen varit i form av en intervjustudie där fem olika företag har studerats. Den empiriska insamlingen har bestått av semi-strukturerade intervjuer. Slutsats: De slutsatser som kan göras efter den genomförda studien är att prenumerationsbaserade företag präglas av ett flertal olika situationsfaktorer som kräver en ekonomistyrning med ett externt och framtida fokus. Kunden är en central del i företagets värdeskapande och det är av stor betydelse att företagen tillvaratar och värdesätter kundens åsikter. I en prenumerationsbaserad affärsmodell är det enkelt för kunden att se ifall företaget har tillvaratagit kundens åsikter, eftersom att detta är möjligt att urskilja redan i nästa månads leverans av produkten. Detta kräver i sin tur att företagen har korta beslutsvägar, till viss del decentraliserad organisation samt ett agilt och processfokuserat arbetssätt. Vilket är nödvändigt för att företagen ska kunna leverera ständig utveckling och förbättring av deras produkt. / Background and problem: The increasingly digitized world has created other conditions for doing business. A shift has been identified where the importance of value and how value is created has changed. The interaction between the company and the customer has become the place where value is distinguished and created. The traditional business model has been challenged to a greater extent by a business model based on subscriptions rather than one- time purchases of a product. A subscription-based business model means that companies have changed their approach towards customers and the ability to establish long-term relationships with customers is of great importance for achieving success. At the same time as a more changing environment requires that companies have a more external focus to be able to be agile and handle market changes. Through a greater focus on customers, the environment and the future a new type of management control system is required. Since the traditional management control system isn't adapted to today's companies and their conditions which makes it insufficient. Purpose: The purpose with this study is to describe and explain which contingencies that are characteristic for companies with a subscription-based business model and how these affect these companies value creation and management control system. The study also aims to contribute with knowledge to companies within the subscription economy. Method: The study's approach has been of a qualitative nature, where the research design has been in the form of an interview study where five different companies have been studied. The empirical collection consisted of semistructured interviews. Conclusion: The conclusion that can be made after the completion of the study is that subscription-based companies are affected by several contingencies that require a management control system with an external and future focus. The customer is a key part of the company's value creation and it is important that companies utilize and appreciate the customers opinions. The subscription based business model makes it easy for the customer to see if the company has taken charge of the customers opinions, since it is possible to distinguish already in the next month's delivery. This requires companies to have short decision-making processes, to a certain extent a decentralized organisation as well as an agile and process-focused operation method. Which is necessary for companies to deliver a constant development and improvement of their product.

In this thesis the candidate explores the apparent gaps between strategy development and strategy implementation (the strategy alignment question), and between business end-user needs and the suppliers of information technology (IT) related products and services. With business intelligence (BI) emerging as one of the fastest growing fields in IT, the candidate develops a conceptual model in which BI is placed into context with other relevant subjects such as strategy development, enterprise architecture and modelling and performance measurement. The emphasis is on the development of processes and templates that support a closed loop control system with the following process steps: - A business strategy is defined. - The implication of the strategy on business processes, supporting IT resources and organizational structure is formally documented according to enterprise architecture principles. - This documented blueprint of the organization helps to implement the selected business strategy. - A performance measurement system is developed and supported by a well-designed data warehouse. - On a regular basis the measurements that were defined to support the implementation of the strategy, together with information from the external environment are interpreted and this analysis leads to either a new strategy, or refinement of the implementation of the existing strategy. Both options may lead to changes in the enterprise architecture, the execution of business processes and/or the performance measurement system. Some of the individual components of the model are supported by existing theories, for example the Zachman Framework for enterprise architecture and the Balanced Scorecard from Kaplan and Norton. The contribution of the author was to position them in the bigger picture to indicate how they can add value with regard to the establishment of business intelligence in organizations. Instead of packaging existing ideas slightly differently under a new name, the author intentionally searched for existing theories to fulfil certain requirements in the Bigger Picture BI Context Model. Apart from a set of templates that were adapted from various other sources and packaged into practical formats that can be used during facilitation sessions, the author has also developed and described the Fourier Model and the Pots of Money Model. The Fourier Model is a powerful conceptual model that helps a business to package solutions for market related requirements through selections of previously defined building blocks (technical components) that can be delivered through various business entities, depending on the requirements of the opportunity. The Pots of Money Model is a quantitative model embedded in a spreadsheet format to illustrate and communicate the effect of spending decisions in one area of the business on other areas. The candidate demonstrates the Bigger Picture BI Context Model in several case studies. The thesis is accompanied by a CD ROM, which contains over 700 references to relevant literature (most of them available in full text) and links to internet web sites, as well as examples of the software templates that support some of the steps in the context model. The following figure depicts the conceptual model in schematic format: (See figure in the abstract of 00front) / Thesis (PhD (Industrial Engineering))--University of Pretoria, 2006. / Industrial and Systems Engineering / unrestricted

The academic publishing sector in South Africa is facing many changes and challenges in a post- 1994 democracy. Most of these changes were brought about by the Higher Education Act No 101 of 1997. Challenges and new trends include new business and threats from multinational corporations; a limited buying market at higher education level; a need for localised content; new emerging technologies in publishing and knowledge distribution; the merging of 36 higher education institutions into 22; escalating book production costs and book prices; a non-book buying and book reading culture; illegal photocopying and widespread copyright infringement; changing student and lecturer profiles including the language of instruction; increasing pressure on academics to publish research; inefficient student loan schemes; decreasing library acquisition budgets and the transformation of the publishing industry itself in terms of BBBEE. Within the midst of all these challenges, publishers are faced with a new trend, that of selfpublishing of academic textbooks, which lecturers then prescribe to their own group of students. Self-publishing implies that authors undertake all processes related to publishing on their own, including the financial risk of publishing a book. There is a multitude of literature available on self-publishing, but very little focuses on this trend within the academic environment. A literature survey of self-publishing provided various reasons and conditions for the existence of the phenomenon. The researcher made use of two questionnaires that were sent to academic campus bookshops and academic self-publishing authors. From the results of these two surveys it is evident that academic self-publishing is an increasing trend in the higher education environment of South Africa. Reasons for self-publishing collected from the literature survey were supported by the empirical research findings from the two surveys. The main reasons for self-publishing in the academic environment include financial incentives; a volatile author-publisher relationship; issues of copyright and control; possible rejection suffered by authors; technological advances and a sense of community service among academics and lecturing staff. The study was able to prove the existence of academic self-publishing in the higher education environment of South Africa. Academic self-publishing is most apparent in the academic fields of Business, Economics and Management Sciences to the extent that it could have far-reaching financial impact on markets that are traditionally lucrative for commercial publishers. Commercial publishers are encouraged to engage with author associations and seek out possible new alternatives to satisfying author needs in a changing market place. / Dissertation (MIS)--University of Pretoria, 2008. / Information Science / unrestricted

“What constitutes corporate publishing?” is the question that motivated the research for this study. It is not easily defined, but can be contextualised as part of the communications and marketing strategy of an organisation. In essence it entails the conceptualisation, planning and realisation of professional publications in an organisation. By conducting interviews with publishing personnel in selected South African banks, best practices pertaining to corporate publishing structures and processes were derived. It was found that traditional book publishing activities, such as commissioning; planning and creating content; reviewing, copy-editing and proofreading; design and layout; production, marketing; printing; and distribution can be used as basis for a corporate publishing venture. The convergence of media, however, is challenging publishers to rethink traditional methods of publishing. Electronic publishing is opening new vistas for organisations as it is an efficient tool for them to build and strengthen their corporate identity and to reach wider markets. To acommodate electronic dissemination, the adoption of an integrated, parallel publishing workflow is proposed in the study. Utilising a single source document for creating multiple formats enhances the publishing process and ensures the longevity of information. In order to draw all the publishing activities in an organisation together in a consistent and cohesive way, a centralised publishing strategy seems to be the most effective solution. The golden thread running through this study is the important role of corporate publishers as service providers in information-rich organisations. / Dissertation (MA (Publishing))--University of Pretoria, 2005. / Information Science / unrestricted

Le développement des biocarburants soutenu par la communauté internationale connait un essor depuis le début des années 2000 à l'échelle mondiale pour réduire les émissions de gaz à effet de serre, répondre aux préoccupations énergétiques des pays industriels et diminuer la pauvreté énergétique dans les pays du sud. Cette stratégie rencontre plusieurs controverses qui portent sur les impacts socio-économiques des biocarburants et les trajectoires technologiques les mieux adaptées aux besoins de développement des pays d'Afrique sub-saharienne. L'objectif de la thèse est de comprendre les déterminants des processus d'innovation technologique sur la production des biocarburants. La thèse pose pour cela deux hypothèses. La première hypothèse structurée par le croisement entre les théories de la transition et les analyses systémiques de l'innovation repose sur le déterminisme institutionnel des processus d'innovation technologique qui structure l'émergence du secteur des biocarburants. La seconde hypothèse suppose que l'émergence et le développement du secteur bioénergétique résulte des conditions d'adoption micro-économiques et territoriales de la production des cultures énergétiques. Le test de ces hypothèses est réalisé en mobilisant un référentiel d'analyse en termes de système d'innovation dans le cas de la filière Jatropha au Burkina Faso. Les résultats soulignent que l'émergence des technologies biocarburants dans les pays d'Afrique subsaharienne est liée aux changements institutionnels induits par les crises énergétiques et environnementales. Ces changements institutionnels activent des ressources favorables à l'émergence et à la dissémination des technologies sur les biocarburants. Au Burkina Faso, ces changements sont impulsés par les politiques européennes et celles d'organisations sous régionales telles que l'UEMOA et la CEDEAO. Une modélisation économétrique permet de manière complémentaire de tester les conditions d'adoption micro-économique et d'implémentation des innovations technologiques sur les biocarburants. Les facteurs structurels de l'exploitation agricole (capital foncier, situation alimentaire, perception) ; la proximité des acteurs de la filière ; ainsi que les variables institutionnelles inhérentes au renforcement des capacités et compétences apparaissent structurants de ces processus d'adoption sur le Jatropha. Cette adoption dépend enfin des modèles technologiques qui permettent d'intégrer d'un point de vue territorial les phases de production de la matière première, transformation et utilisation dans un mécanisme de réponse aux besoins prioritaires du développement du Burkina Faso. / Biofuel development supported by the international community expands since the early 2000s globally to reduce emissions of greenhouse gases, meet the energy concerns of industrial countries and reduce energy poverty in the countries of south. This strategy meets several controversies that address the socioeconomic impacts of biofuels and the most appropriate technological trajectories to the needs of developing countries in sub-Saharan Africa. The aim of the thesis is to understand the determinants of the process of technological innovation on the production of biofuels. The thesis raises two hypotheses for this. The first assumption structured by intersection between the theories of transition and systemic analysis of innovation based on institutional determinism of technological innovation process that structures the emergence of the biofuel sector. The second assumption is that the emergence and development of the bioenergy sector resulting conditions of micro-economic and territorial adoption of the production of energy crops. The test of these hypotheses is achieved by mobilizing an analytical reference in terms of innovation system in the case of the Jatropha sector in Burkina Faso. The results highlight the emergence of biofuels technologies in sub-Saharan Africa is related to institutional changes induced by the energy and environmental crises. These institutional changes enable favorable resources to the emergence and diffusion of technology on biofuels. In Burkina Faso, these changes are driven by European policies and those of sub-regional organizations such as UEMOA and ECOWAS. Econometric modeling allows complementary way to test the conditions of microeconomic adoption and implementation of technological innovations on biofuels. Structural factors of the farm (land capital, food situation, perception); the proximity of the actors of the sector; and institutional variables inherent in capacity building and skills appear structuring of these processes of adoption of Jatropha. This adoption also depends technological models that integrate a territorial perspective the production phases of the raw material, processing and use in a response mechanism to the priority needs of the development of Burkina Faso.

Competition for talent is heating up and will probably intensify, since demographic trends make it increasingly difficult for companies to replace valued employees when they retire. In response, many companies are trying to sharpen the way they market themselves to recruits, by applying branding techniques to recruitment. For a company to exploit its brand effectively when it fishes for talent, it must think of recruits as customers, determine which corporate attributes matter most to specific types of recruits, and understand how best to reach them. This diploma thesis analyzes Belgian business graduates' aspirations in terms of first employment and their perception of our company as potential employer and brings constructive and creative recommendations on how to improve its position as employer of choice.

Les organisations interprofessionnelles (OIP), complètement nouvelles dans le cadre institutionnel agricole argentin, sont nées au sein d’un processus plus large de transformation du secteur où la technologie va tenir une place de plus en plus centrale. La vocation innovatrice manifestée par les OIP a suscité le besoin de comprendre leur rôle dans les processus d’innovation des filières.Cette thèse a fait apparaître, à partir de l’étude de trois cas (l’OIP de la filière du soja, l’OIP de la filière du tournesol et l’OIP de la filière du riz) que les OIP ont des rôles différenciés dans les processus d’innovation des filières. Nous avons pu montrer que les différences dans ces rôles sont liées à la fois aux formes d’insertion des filières argentines dans des chaines de valeur globales et aussi au type d’acteurs qui dominent les systèmes d’innovation de chaque filière. Le cadre théorique mobilisé combine des approches institutionnalistes des mécanismes de coordination des acteurs avec des approches de la géographie critique qui permettent de rendre compte des processus qui conditionnent le développement des filières agroalimentaires concernées. L’analyse empirique, basée sur la triangulation de sources d’information et de techniques d’analyse de données différentes, nous a permis de mettre en relation les différentes dimensions de la problématique et d’interpréter les rôles des OIP dans les processus d’innovation. / Interprofessional organizations (OIP), new actors in the Argentine’s agricultural institutional framework, were born in the context of a broader transformation of the sector where technology takes an increasingly central place. The innovative spirit manifested by the OIP raises questions about its role in the innovation process of the value chain. This thesis shows, from the study of three cases (the soybean chain OIP, the sunflower chain OIP and the rice chain OIP) that the OIP have differentiated roles in the innovation process. We have shown that differences in these roles are related to the forms of insertion of Argentine industries in global value chains and also the type of players that dominate the innovation systems of each chain. The framework combines institutionalist approaches to the coordination mechanisms of the actors in the innovation processes with a focus on critical geography, which can account for the processes that affect the development of agricultural chains. / Las organizaciones interprofesionales (OIP), actores completamente nuevos en el mapa institucional agrícola argentina, nacieron en el marco de un proceso más amplio de transformación del sector donde la tecnología ocupa un lugar cada vez más central. La vocación innovadora manifestada por las OIP lleva a interrogarse sobre su papel en el proceso de innovación de la cadena de valor. Esta tesis muestra, a partir del estudio de tres casos (OIP de la cadena de la soja, la cadena OIP girasol y las OIA del sector arrocero) que la OIP tienen roles diferenciados en el proceso de innovación y que las diferencias están vinculadas a las formas de inserción de las en las cadenas globales de valor y también el tipo de jugadores que dominan los sistemas de innovación de cada cadena. El marco teórico combina los enfoques institucionalistas de los mecanismos de coordinación de los actores en los procesos de innovación con el enfoque de la geografía crítica, que puede dar cuenta de los procesos que afectan al desarrollo de las cadenas agroalimentarios.El análisis empírico, basado en la triangulación de las fuentes de información y diferentes técnicas de análisis de datos, nos ha permitido relacionar las diferentes dimensiones del problema e interpretar los roles de las OIP en proceso la innovación.

Dados governamentais abertos é resultado, de uma série de novas exigências da sociedade para com seus governos. Entre estas exigências pode-se citar a busca por uma maior transparência e participação na gestão dos recursos públicos, maior controle sobre a qualidade dos serviços prestados, além de uma maior responsabilização por parte de seus gestores sobre a utilização destes recursos. Os governos para tentar atender a estas exigências fazem uso dos recursos da tecnologia de informação e comunicação, assim surge à possibilidade da disponibilização de dados em formato aberto, que tem como premissas básicas a transparência, colaboração e inovação. O tema dados governamentais abertos assume grande importância, pois aproximadamente uma centena de países desenvolve iniciativas neste sentido. De forma paralela a este fato, gestores públicos enfrentam desafios na implementação de projetos de dados governamentais abertos, pois este requer múltiplas interações entre governos e sociedade e ainda não existe um entendimento disponível em guias, ferramentas ou teorias para lidar com a abertura de dados no setor público.Este trabalho teve como objetivo principal propor um modelo genérico de produção e utilização de informações sob a ótica conceitual da cadeia de valor; o modelo visa atender as necessidades do ecossistema brasileiro de dados governamentais abertos. A coleta de dados foi realizada através de entrevistas com membros de governos e da sociedade. Os resultados apontam que possíveis vantagens são visualizadas por membros de governos e da sociedade pela atuação em dados governamentais abertos. Os resultados confirmam a existência e necessidade da formação de redes entre governos e sociedades, bem como a importância de diversos atores da sociedade que atuam neste ecossistema, como fatores facilitadores ou motivadores para a realização de diversas atividades. Existem diversas barreiras ou fatores inibidores, em especial com questões relacionadas a legislação e qualidade da informação disponibilizada. O modelo proposto aponta atores e respectivas atividades, bem como quais fatores podem prover sustentabilidade ao desempenho das mesmas e indica como determinada atividade impacta as demais. De forma coerente as premissas da cadeia de valor, o modelo proposto contém atividades primárias e secundárias. / Open Government Data is the result of new demands from society towards their governments. Among these demands can cite search for greater transparency and participation in the management of public resources, greater control over the quality of services, and greater accountability on the part of its managers on the use of these resources.Governments to try to meet these demands make use resources of information technology and communications and the possibility arises of providing data in open format. Open Government Datahas the basic premises transparency, collaboration and innovation. The theme is of great importance because approximately one hundred countries are developing initiatives in this sense.Parallel to this fact, public managers has challenges in implementing initiatives of Open Government Data. This requires several interactions between governments and society and there is still no understanding available in guides, toolsor theories to deal with the opening of data in the public sector.This work aimed to propose a generic model of production and use of information in the conceptual view of the value chain. The model aims to meet the needs of the Brazilian ecosystem Open Government Data collection was conducted from interviews with government members and society.The results indicate that members from government and society realize benefits by acting in Open Government Data.The results confirm the existence and or need for networking among governments and societies.Actors from society that act as factors that facilitate or motivate for performing various activities by others actors.There are several barriers, specially with legal factors and information quality.The model indicates actors and their activities, and what factors can provide sustainability to the same performance and indicates how a particular activity impacts the others. Consistently the assumptions of the value chain, the model contains primary and secondary activities.

Ma thèse porte sur les chaines de valeurs globales et le commerce international.Les progrès technologiques et la baisse des coûts de communication ont favorisé la fragmentation des processus de production entre différents pays et secteurs et l’expansion des chaines de valeurs globales. Cette nouvelle organisation entraine des modifications majeures au niveau des flux du commerce international et une interdépendance croissante des économies.L’objectif de cette thèse est donc d’étudier l’impact de l’organisation des chaines de valeur globales sur les problématiques du commerce international, que ce soit à l’échelle macroéconomique (avantages comparatifs des pays) ou microéconomique (performance des entreprises).Il s’agit d’une thèse sur travaux, composée de trois chapitres.Le premier chapitre analyse l’organisation d’une chaine de valeur globale à partir des avantages comparatifs. Je montre ainsi que les avantages comparatifs sont différents lorsqu’ils sont mesurés à l’aide de données commerciales en valeur ajoutée par rapport aux données commerciales traditionnelles. Cette nouvelle mesure des avantages comparatifs implique un schéma de spécialisation sectorielle différent dans une chaine de valeur globale. L’identification des facteurs à l’origine des avantages comparatifs dans ce contexte de fragmentation met en évidence le rôle crucial de la qualité institutionnelle, son effet étant plus important que les facteurs traditionnels tels que le travail ou le capital.Les deux derniers chapitres étudient les chaines de valeur globales à travers l’organisation des entreprises dans le secteur aéronautique en France, dans la région Midi-Pyrénées Aquitaine.Le deuxième chapitre évalue l’impact du recours à la sous-traitance sur les performances des entreprises de l’aéronautique, en se basant sur des données d’enquête de l’Insee de 2006 à 2011. J’étudie plus particulièrement l’impact de la localisation de la sous-traitance et je démontre que les entreprises ayant recours à la sous-traitance domestique et internationale affichent, en moyenne, une productivité plus élevée que celles qui ne sous-traitent pas ou sous-traitent uniquement au niveau domestique. L’utilisation de régressions quantiles montre que l’effet est d’autant plus élevé pour les entreprises les moins productives.Enfin, le dernier chapitre étudie l’impact de la crise financière de 2007-2008 sur les entreprises du secteur de l’aéronautique. Je distingue deux types d’entreprises, celles qui produisent des biens différenciés et celles qui produisent des biens standardisés. Les résultats mettent en évidence la plus forte résilience des entreprises produisant des biens standardisés. Cette meilleure résilience s’explique par une plus grande capacité à diversifier leurs marchés en cas de crise, notamment via l’utilisation de logiciels facilitant la sous-traitance et diminuant les coûts de coordination ainsi que leur statut d’exportateur, qui permet d’accéder plus facilement aux marchés internationaux. / My thesis is about global value chains and international trade.Technological progress and lower communication costs have foster the fragmentation of the process of production across countries and sectors and the expansion of global value chains. This new organization led to major changes in international trade flows and a growing interconnectedness of economies.The objective of this thesis is to study the impact of the organization of global value chains on international trade either at the macroeconomic level (countries’ comparative advantages) or microeconomic (firm performances).This thesis is organized on three chapters. The first chapter assesses the impact of global value chains on the comparative advantages of countries based on value added trade data.In this first chapter, I investigate the organization of global value chains based on comparative advantages. I show that comparative advantages are different when computed using value added trade data compared to gross trade data, which leads to a different sectoral specialization in a global value chain. The identification of the determinants of comparative advantages shows the importance of the quality of institutions, its impact is greater than traditional factors like labor or capital.The two last chapters study global value chains through plants in the aircraft industry in France, in the region Midi-Pyrénées Aquitaine.The second chapter provides empirical evidence of the impact of outsourcing and its origin on plant level performance in the aircraft sector based on panel data from 2006 to 2011. Specifically, I study the impact of the localization of outsourcing and show that, in average, plants that outsource their activities both domestically and internationally exhibit a higher productivity level, compared to plants not outsourcing or outsourcing only domestically. Quantile regressions shows that this effect is higher for lower productive plants.The last chapter describes the impact of the 2007-2008 financial crisis on plants on the aircraft sector in France. I identify two types of plants, generic outsourcers, producing standardized goods, and contractual outsourcers, producing customized goods. I show that generic outsourcers were more resilient during the crisis than contractual ones. Digitization, which reduces coordination costs and exporting activities, which permits to diversify their markets, explain part of the resilience of generic outsourcers to the crisis impact.
