The article deals with the peculiarities of formation and enforcement of the national investment security in terms of distribution of investment flows and demand for investments. The global market for investment resources was analyzed and its impact on the investment needs and security of the individual countries was evaluated. At the methodical level, the interrelation and interdependence of components of national investment security were defined. Leading security indicators were identified and characterized taking into account investment risks factors. A Process model of the country's investment security system was developed considering the risks and threats from the external environment and economic issues from the internal environment. The algorithm of complex assessment of the investment security of a country, based on the identification of stages and components of use of investments at the national level, was formed. A Model for evaluating the country's individual investment security measures was developed.

Purpose. To substantiate the methodological approach to the development of research components of the integrated system of complex economic analysis and internal control of the enterprise. Methodology. The main methods of this research are statistical methods, the latter being used for processing of statistic data; methods of formalization and mathematical simulation used for development of conceptual analysis base to control the enterprises activity. Findings. A complex model of diagnostics of enterprises activity in a competitive environment is proposed, which is based on the methodology of complex economic analysis with the use of financial and non-financial indicators. To assess the competitive advantages of the enterprise, we offer an algorithm to calculate an integrated indicator of the level of its competitiveness using a balanced scoring system. Originality. In the course of research, the scientific and methodological approach to a complex evaluation of influence of a research component on development of competitive strategy of the enterprise was developed. Unlike the existing ones, this approach involves: - development of an integrated system of complex economic analysis and internal control over business processes of enterprises with the use of modern information technologies, which allows assessing their competitiveness, forming a development strategy; - methodical procedures of internal control of the enterprise with the use of financial and operational budgets and management reports based on a balanced scoring system, using CVP-analysis, which allows forming flexible budgets. Practical value. The results of the study can be used by practitioners, scientists, government officials to monitor the development of the corporate architecture, to study enterprise development processes.

Entrepreneurship ensures the development of both the national economy and the population’s, well-being so it embodies a necessary process and factor for ensuring sustainable development. In the long run, sustainability is impossible without development and the entrepreneurship as one of its main stakeholders plays a triple role, acting at the same time as a significant factor, part of the economic component and a mechanism ensuring the sustainable development. The article examines issues of sustainable development entrepreneurship; considered is the substantial characteristics of management tools for system-integrated sustainable development entrepreneurship management, thus offering a system of digital tools services for sustainable development entrepreneurship digital platform and model for sustainable development entrepreneurship. The theoretical and methodological approaches to business development management proposed are designated to provide management focusing on sustainable development, system-integrated nature, anticipatory influence, use of rapidly growing digital capabilities, therefore forming an innovative basis for management and its object development. Its components are: a system of digital tools, a model of socially responsible business ideas and business projects selection; business models for sustainable development entrepreneurship. The study results are of essential practical importance for the process of one’s own business conducting with the use the rapidly growing opportunities opening.

Topicality. The concept of sustainable development synthesizes anthropocentric and biospherecentric principles and provides for optimal use in the economic and non-economic processes of the natural component, aligning the impact of man on nature and the ability of the latter to bear anthropogenic load, which will provide the ability of future generations to satisfy ecological needs. As people and their needs are at the center of socio-economic development, the notion of "sustainable human development" associated with the process of expanding individual choices in various fields is becoming increasingly relevant today: from guaranteeing economic, social and political rights and freedoms to the possibilities of creative self-realization and improvement. Aim and tasks. Despite the extensive study of sustainable development in the domestic and foreign scientific environment, a detailed study of the genesis of the concepts of "sustainable development" and "sustainability", as well as the components of sustainable development, is required. The purpose of the article is to review, systematize and analyze approaches to sustainable development, and compare them, as well as to formulate a paradigm of sustainability from the first appearance of the prerequisites of this concept to the origins and generalization of the genesis of the concept of sustainable development. Research results. Therefore, the result of the study is the formation of the paradigm of sustainability from the first appearance of the preconditions of this concept to the origins and generalization of the genesis of the concept of sustainable development. Thus, the inclusion of only three components in the concept of sustainable development (society, economy, environment) is common practice, but it is not the only correct component. Conclusion. Given the uncertainty in the domestic scientific environment of the system of sustainable development and the lack of complete analysis of approaches to its implementation, it is necessary to review and systematize these approaches, to compare them. This will allow us to understand sustainable development, not as an abstract phenomenon, but as a truly global paradigm for human survival in the third millennium, the transition to which is a translational process.
