The article reveals the main ecological and natural and technogenic prerequisites for the formation of adverse environmental conditions in today's Ukraine. The authors consider the functional dimension of modern threats to sustainable development and propose a classification depending on their origin, including classic and synergistic threats, transformations of human consciousness as well as social, ecological and economic imbalances. It has been found that the main problems of institutional ensuring of the environmental protection in Ukraine are primarily caused property transformation, economic relations, restructuring of the mechanisms relating to the functioning of industrial enterprises, which is aggravated by the difficult social and economic situation in the regions. The study is devoted to the development of conceptual bases, principles and scenarios of modelling of environmental safety in the system of sustainable development. It considers artificiality, structural instability, quantifiability and duality of environmental safety. Factor and time components of safety determined according to the modified stochastic approach are also disclosed. They interpret the dependence of the environmental competitiveness of the region with regard to environmental hazard (component by component), innovation and investment activity aimed at improving the state of the environment. The authors of the paper argue that safety modelling, in view of institutional transformations (or responses), characterises the level of response to challenges, taking into account the analysis of environmental safety issues in terms of sustainable development, the state of legal mechanisms, the struggle against threats and risks, etc. In the light of the aforementioned, the authors of the article have developed an econometric model of the period and change in the dependence of the ecological competitiveness of the territory with regard to environmental hazard, innovation and investment activities aimed at improving the state of the environment. The obtained results, based on the modified stochastic approach using real information that quantitatively reflects the features of such processes, have prove a significant impact of genetic factors on the competitiveness of Ukraine.

The aim of the article is to outline theoretical and methodological approaches to harmonizing the interests of stakeholders in the system of sustainable finance on a platform approach to the organization of stakeholder interaction as partners in the process of ensuring sustainable management. It is established that the organization of sustainable management concerns the formation of financial relations in the interests of the maximum number of stakeholders, which will contribute to the homeostatic development of the economic system. The place and role of the financial component in harmonizing the interests of stakeholders are determined. Stakeholders in the financial relations of sustainable management are considered as a system set of groups and individuals from the internal and external environment of economic entities that provide homeostasis of the economic system through optimal distribution and use of financial resources in the process of interaction. A matrix of differentiation of stakeholders is constructed according to the importance of participation in the management process and the degree of their interest in decision-making. Passive and active hosts and users have been identified, among whom it is necessary to establish interaction to transfer as many participants as possible to the categories of active hosts and users and apply platform technological innovations for this purpose. It is determined that the stakeholders-hosts should act as agents of the territorial business ecosystem, forming the trend of sustainable management through collaborative interaction with each other. It was found that in the future it is necessary to create a full-fledged system of sustainable finance, in which in addition to the existing components of responsible investment and banking, sustainable insurance and stock markets, it is necessary to develop a sustainable public sector financial system, including sustainable fiscal and budgetary pension system and sovereign financing of sustainable development. The formation of the logistic cycle of sustainable economic reproduction due to the action of regulatory, stabilization, inclusive and other mechanisms of the system of sustainable finance is shown.

The conceptual and analytical approach to the definition of an integrative base of sustainable development of territories is proposed, which is based on the idea of construction of economic space and creates real conditions for the establishment and deployment of territorial economic integration. It is proved that the effect of the realization of the economic meta space of the state is influenced by the factor of reorganization of the regional map by cascading format of consolidation of industrial-economic, inter-sectoral and interregional interaction. It is recognized that it is expedient to take into account European economic-statistical principles when creating ten territorial economic and economic districts, the format and scale of which will correspond to the key principles of the liberal-social market model of spatial development.

For Ukraine’s conditions, it is important to find new forms of organization of economic activity, which will ensure the overcoming of “catching-up” of the world economy. It is advisable to solve the problem in terms of determining the features of the national space for sustainable development. At the same time, objectively, there is a need to adapt the definition of “space” as such to the practice of environmental and economic development management. From a methodological standpoint, the issue is to use the post-industrial approaches to define economic processes with a focus on the category of “interest”. Since economic space of the post-industrial type is formed by the flows of “interests” of business entities, which circulate and determine its structure, attention is focused on domination of energy and information in communicative processes. From the standpoint of the functioning of a proper communicative field, the effect of economic activity is provided by reducing the parameters of transaction duration and then reducing the costs to a corresponding acceptable level. Evolution of the communication system indicates a change in the nature of interaction of business entities with environment. The main issues are the ecological and economic encodings of the life space, which gradually transform into everyday reality and form the corresponding cognitive frames. Therefore, an important point is the search for modern forms of economic self-sufficiency of functioning of ecological systems at the level of requirements for their safe existence at the expense of rational use of natural resources assets. The author emphasizes the expediency of focusing on decentralized forms of managing the process of ensuring the ecological and economic development of territories, taking into account the relevant competences of local economic systems within the definition of their communication fields. Aforementioned approach can be fully solved in the framework of the so-called platform economy. As a phenomenon of macroeconomic level, the platform economy provides guidance on changing the mechanism of cost formation at the grassroots level. The ecological and economic concept of sustainable development fits into general trends associated with transformation of the markets towards expansion of network interactions, since business as well starts to develop according to the similar to natural ecosystem laws.
