The purpose - A critical analysis of the main literature contributions dealing with the digital transformation of social subsystems in COVID-19, focusing on digital government system innovations. According to the current research, the following research questions have been prepared: What state-of-the-art approaches and solutions emerged in the COVID-19 period (or increased digitalisation) and will be a key socio-technological factor in future development digitalisation of urban (smart) ecosystems? Design/methodology/approach - The automated content analysis was provided with the software Leximancer 5.0. The authors prepared a topic analysis function to determine the most frequent topics and contents and use the automated content analysis's extraction of statistically manipulative information about the presence, intensity, and/or frequency of thematic and/or stylistic features of texts. Findings - It is expected that the emergence of a cyber-physical ecosystem will arrive soon, with smart communities having an important impact on changing the existing approaches, for example, learning, medical treatment, and smart governance. Originality/value - The chapter presents the possible changes in the post-COVID-19 world, which will accelerate processes for the emergence of the technological advanced urban environment and will be based on the outgoing digitalisation of processes. Furthermore, the chapter aims to present new knowledge based on the current findings of the future possible interaction between the citizens and governance (from communication to decision making and self-governance tools). The issue of citizens' trust in sharing their data with public infrastructure is also addressed. Research/ Practical/ Social/ Environment implications - The COVID-19 outbreak caused massive disruption to the industry and urban social ecosystems. The pandemic impacted drivers of a nation's economy and caused changes, such as the emergence of remote working, a bike-riding spike, different smart city projects were postponed or re-aligned, and technological projects aimed at protecting against COVID-19 have been given priority. Attention must also be paid to smart technologies, such as contact tracing and surveillance tools, raising concerns about privacy and human rights.Research limitations - The particular research limitation of the chapter is that the authors used a mixed-method for literature content research
