Esta dissertação tem como objetivo investigar a criação de valor dos modelos de negócio
digitais, o seu impacto e a sua dependência dos utilizadores. Analisa-se como os modelos de
negócio digitais são a nova economia e como o sistema fiscal internacional não é capaz de
acompanhar certas mudanças. O resultado é a perda de soberania fiscal para as empresas
bigtech. Por conseguinte, o estudo procura explorar os obstáculos que o regime fiscal
internacional enfrenta e, como resposta, refletir se o utilizador pode ou não ser considerado o
novo nexo do regime fiscal internacional.
A investigação começa por reconhecer os diferentes modelos de negócio digitais, os modelos
de negócio emergentes, o seu funcionamento e a sua importância para o desenvolvimento
económico do mundo. Além disso, são examinados os conceitos controversos de participação
do utilizador e de criação de valor como duas importantes características-chave da economia
digital.
Assim, o estudo prossegue combinando os modelos de negócio digitais com o regime fiscal
internacional, explorando os enquadramentos teóricos que conduziram às infindáveis questões
que têm sido discutidas nas últimas décadas e, consequentemente, às contínuas propostas
internacionais e europeias para a resolução dos desafios digitais.
Por fim, a dissertação prossegue com a análise de um caso prático, onde é considerada uma
empresa multinacional, numa perspetiva financeira e de gestão, retirando conclusões sobre os
desafios quando se coloca a questão de "poderá o utilizador ser o próximo nexus?”

Finally, the dissertation continues by analyzing a practical case study, where it is taken into consideration a multinational enterprise, from a financial and management perspective, drawing conclusions about the challenges when the question of “could the user be the next nexus?” is called into question.
