The aim of the article is to enhance the management of the development of critical infrastructure in Ukraine at the regional level. The study substantiates the theses. First, in the context of devastating events and high risks to Ukraine’s critical infrastructure, as well as considering the processes of decentralization, it becomes urgent to strengthen the role of regions in ensuring the resilience, restoration, and development of critical infrastructure. Secondly, the effective functioning and development of critical infrastructure require appropriate management mechanisms. Thirdly, it is important to approach the management of the development of critical infrastructure from the perspective of regional and community development, and it becomes most efficient when carried out at both the State and the regional levels, relying on local potential and experience, with the regional community playing a significant role. Initially, data on losses and damage to infrastructure during military operations are presented, highlighting losses and damages incurred by the regions of Ukraine. Further, the factors and global experience of countries regarding the regional level of critical infrastructure management are analyzed. It is proposed to improve the management of critical infrastructure in Ukraine at the regional level based on the creation of regional coordination centers for the development of critical infrastructure with working groups. The functions of the regional coordination centers for the development of critical infrastructure are allocated. Prospects for further research in this direction involve addressing issues related to the information support for the management of critical infrastructure in Ukraine at the regional level.

The aim of the article is to develop approaches to the analysis and assessment of the functioning and development of the IT sectors of critical infrastructure in the economy of the country and its regions. The functioning of the IT sectors of critical infrastructure in the national economy is analyzed on the basis of data from the system of national accounts on indicators of output, intermediate consumption, gross value added, wages of employees, other taxes, gross profit, mixed income, the share of the sector in the country’s GDP, the number of employees in the sector, and volumes of exports. The regional activity of the IT sectors of critical infrastructure is analyzed. Based on the results of the carried out analysis, it can be determined that in 2017–2021 there is also some instability by several indicators: the negative dynamics of the functioning of the IT sectors of critical infrastructure in the national economy, the share of the IT sector in the economy of Ukraine is insignificant. The pre-war period of the functioning of the critical infrastructure IT sector in the national economy is characterized by a certain decline in the sector. Martial law gave a new impetus to the development of the IT sector in regions distant from hostilities. The authors have allocated the factors of development of IT sectors of critical infrastructure that support and strengthen such characteristics as functionality, rapid adaptability to turbulent operating conditions, continuity in work, sustainable confrontation and rapid recovery after any impact of threats, increasing the sustainability of the national economy. Prospects for further research are the elaboration of issues of an effective financial and economic mechanism for the development of critical infrastructure, public-private partnership, multi-channel financing.

The aim of the article is to improve the classification and systematization of risks of the country's critical infrastructure based on the study of world experience. Analyzing and summarizing the world's scientific and practical achievements regarding approaches to the classification and systematization of critical infrastructure risks, it was found that, despite slightly different approaches to their classification and systematization, a certain similarity is also traced, but still, taking into account the growth in the number and variety of risks, their classification and systematization need to be improved. As a result of the study, a classification and systematization of risks of the country's critical infrastructure has been proposed, which includes a number of features: by the level of occurrence; by belonging to critical infrastructure facilities and services; by the nature of the impact; by source of origin; by sector of occurrence. The classification and systematization of risks is necessary in order to better design, plan and implement measures and investments that will limit, neutralize or avoid negative consequences (energy, social, economic, etc.) arising from the impacts of risks. Prospects for further research in this direction are approaches to assessing the financial, economic and social consequences of possible and real risks to the country?s critical infrastructure, taking into account the cascading nature of modern risks.
