Capturing Information and Communication Technologies as a General Purpose Technology / Les technologies de l'information et de la communication, une technologie génériqueLe Hir, Boris 20 November 2012 (has links)
Cette thèse a pour objet l'étude des Technologies de l'Information et de la Communication (TIC) en tant que Technologie Générique (TG) ainsi que leur rôle dans l'évolution de la productivité du travail aux Etats-Unis et en Europe durant les dernières décennies. La thèse est constituée de trois parties axées chacune sur l'une des trois propriétés fondamentales des TG: le progrès rapide de la technologie, l'ubiquité de la technologie et la capacité à créer des opportunités technologiques. La première partie décrit, dans un premier chapitre, l'innovation dans le domaine des TIC, en commençant par un bref historique de ces technologies, suivie d'une analyse des données contemporaines sur l'innovation dans ce domaine. Elle montre en particulier comment les Etats-Unis ont été, jusqu'à présent, plus performants que les pays Européens dans le développement des TIC. Dans un deuxième chapitre, cette première partie inventorie les difficultés de mesures induites par la vitesse et la nature du changement généré par ces technologies. La seconde partie de la thèse traite de la nature ubiquitaire des TIC. Elle décrit d'abord la diffusion des TIC au cours du temps à travers les pays et les secteurs économiques, puis, établit une revue de la littérature sur la contribution directe de la diffusion des TIC à la croissance de la productivité du travail aux US et en Europe. Le second chapitre de cette partie s'intéresse au comportement de demande de facteurs de production dans les secteurs producteurs de TIC ou intensifs en utilisation des TIC. Enfin, la troisième partie de la thèse se concentre sur la capacité des TIC à générer des opportunités d'innovation. Pour cela elle identifie d'abord la nature des innovations complémentaires et les efforts menant à ces innovations. Elle montre alors la nécessité d'améliorer la comptabilité nationale afin de prendre en compte ces efforts comme des investissements. Cette partie révèle ensuite que, dans les onze pays européens étudiés, le problème est particulièrement concentré sur quelques pays qui investissent peu en TIC et en actifs innovants et que ces deux types d'efforts sont complémentaires. / This thesis aims to study Information and Communication Technologies (ICT) as a General Purpose Technology (GPT) and their role in the labor productivity evolution in the United States and Europe during recent decades. This thesis is organized in three parts corresponding to the fundamental GPT features: the wide possibilities for development, the ubiquity of the technology and the ability to create large technological opportunities. The first part depicts, at first, the innovation in ICT, beginning with a short historical review of ICT inventions followed by the analysis of current data on innovation in this field. In particular, it shows how the US was better than the European countries in inventing ICT until now. Second, this first part makes an inventory of measurement difficulties due to the rate and the nature of the change created by such technologies. The second part of the thesis deals with the ubiquitous nature of ICT. It first describes the ICT diffusion across countries and industries and reviews the economic literature on the direct contribution of ICT on labor productivity growth in the US and Europe. The next chapter studies the factor demand's behaviour in sectors that are either ICT producers or ICT intensive users. The third part focuses on the ICT ability to create opportunities for complementarity innovations. Firstly, it identifies the nature of ICT complementary innovations and the corresponding efforts. It shows, then, that national accounts must be improved in order to take these efforts into account as investments. Secondly, this part shows that, among the eleven European countries studied, the problem is highly concentrated in a few countries that invest less both in ICT and in innovative assets and that these two types of effort are complementary.

Perceived Affordance and Socio-Technical Transition: Blockchain for the Swedish Public Sector / Uppfattad görlighet och socio-teknisk övergång: blockkedjor för svensk offentlig sektorJONSSON, JOHAN R. January 2018 (has links)
The Swedish public sector is under constant pressure to improve processes and services through further digitalization. Blockchain is a novelty technology which shows promise of enabling functionalities which are desired within the sector. However, as the technology is still in its infancy, the practical value it could offer the sector remains unproven. In this master thesis, the socio-technical transition of the public sector for adopting blockchain is analyzed using the multi-level perspective framework. The sector is operationalized as an incumbent socio-technical regime and blockchain as a collection of niche innovations. Affordance theory and the multi-level perspective are combined to analyze how the perception of blockchain affects the potential transition pathways. The primary empirical data is gathered through a series of interviews with key individuals from both the Swedish public sector and blockchain community, as well as from attending blockchain events. Secondary data is gathered through the review of various types of literature regarding the topic. The findings of the thesis show that the practical value and functionalities that blockchain offers and that match the needs of the sector are verification, authentication, traceability, automating simple logical functions, and digitizing unique value. The identified conceptual solutions deemed suitable today are: blockchain for identity management, blockchain for data verification, blockchains for property registers of, e.g., vehicles and real estate, and external industry blockchains for improved traceability of, e.g., supply chains and sales records. The thesis also derives recommendations for the public sector indicating that, e.g., active education, revision of regulation, and international cooperation would further a potential transition towards blockchain. It also finds that perceived affordances of a technology in its early stages affect the transition pathways; barriers of entry, number of potential adopting application sectors, the level of coordination, and the available resources for development are influenced by the perceptions. / Svensk offentlig sektor utsätts konstant för påtryckningar gällande fortsatt digitalisering av processer och tjänster. Blockkedjan är en ny teknologi som påvisar potential att kunna tillgodose funktioner önskvärda inom den offentliga sektorn. Dock är teknologin fortfarande i ett begynnande stadie och dess praktiska värde är ännu obevisat. I detta examensarbete analyseras offentliga sektorns potentiella socio-tekniska övergång till att ta blockkedjor i bruk med hjälp av multinivåperspektiv-ramverket. Sektorn operationaliseras som en befintlig socio-teknisk regim och blockkedjor som en samling av nischinnovationer. Görlighetsteori och multinivåperspektivet kombineras för att analysera hur uppfattningen av blockkedjor påverkar de potentiella övergångsvägarna. Primära empiriska data samlas in genom en serie av intervjuer med nyckelindivider från både svensk offentlig sektor och blockkedjegemenskapen, samt även från deltagande i blockkedjearrangemang. Sekundära data samlas in genom en studie av diverse typer av litteratur gällande ämnet. Examensarbetets resultat påvisar att det praktiska värdet och funktionaliteterna som blockkedjor tillgodoser och som passar med offentliga sektorns behov är verifikation, autentisering, spårbarhet, automatisering av simpla logiska funktioner, samt digitalisering av unika värden. De identifierade konceptuella lösningarna som bedöms lämpliga i dagsläget är: blockkedja för identitetshantering, blockkedja för dataverifikation, blockkedjor för egendomsregister, t.ex. för fordon och bostäder, samt externa industriblockkedjor för förbättrad spårning, t.ex. av försörjningskedjor och försäljning. Examensarbetet härleder även rekommendationer till offentliga sektorn, innefattande exempelvis aktiv utbildning, revision av reglementen, samt internationellt samarbete. Resultaten påvisar även att den uppfattade görligheten av en teknologi i ett tidigt stadie av innovation påverkar övergångsvägarna in i en regim. Detta genom att uppfattningarna influerar inträdesbarriärer, antalet potentiella applikationssektorer, koordinationsnivån, samt mängden tillgängliga resurser.
