Dynamika obchodního modelu v telekomunikacích

This doctoral thesis is focused on the most progressive part of telecommunications nowadays, on Internet governance and Internet domain name system. This field is not only highly interesting, but only very little researched area from the point of view of economics sciences compared to the traditional fields. Recently, the question of Internet governance was highlighted, but it has been neither resolved nor sufficiently discussed so far. The theory does not answer many questions raised by the praxis sufficiently. The aim of the thesis was to describe the branch in detail and to develop an original model, which would characterise the dependency of the number of registrations on other indicators. This doctoral thesis of Regina Filipova Fuchsova brings a detailed analysis of factors influencing the domain name system. This is the first analysis of this art ever, which targets top level domains .cz and .eu. Typology of TLD registries and connection of domain name selection with the company strategy are further new findings. Based on own analysis and case studies, the author concludes, that there is a relatively strong dependency of the number of registered domains under the respective TLD on national economy characteristics and that the model of the relationship of a ccTLD registry and respective government significantly varies in particular countries. This is due to the historical development and national specifics. The author further came to the conclusion, that national and generic TLDs are partially substitutes and partially complements on national markets. It depends on concrete market and the degree of ccTLD liberalisation, because generic TLDs act as substitutes to the country code TLD on not liberalised markets and/or where the ccTLD is rather expensive. As for the liberalised markets, the growth of a ccTLD goes hand in hand with the growth of gTLD and they compete less. National TLDs of the EU countries and the European TLD .eu show the nature of complements according to the statistical analysis. There are significant theoretical and practical contributions of this work because of its wide content and original analysis in this field. The findings can be practically used for registry benchmarking and ideas related to the delegation of new top level domains.
