The main essential aspects of the country economic security as a foundation for structural change and sustainable development of the national economy, strengthening its competitiveness, improvement of the economic entities efficiency are formulated in this paper. The processes affecting the economic security at the state, regions and individual enterprises levels are identified. Taking into account the available classifications of the economic security components, the role of information and cybersecurity is highlighted. It is determined that almost in all classifications of information security in one form or another is considered as an opportunity for information support and protection of confidential information of the socio-economic system. It is proved that «cybersecurity» category is gradually shifting from micro to macro level, from the problems of information protection on individual devices in local networks to the creation of a single cybersecurity system as a full component of national security at the state level. The assessment of cyberspace as the environment for potential criminal actions in the field of unauthorized access to the confidential information, software failures, automated systems functional breakdowns is carried out. It is identified how such characteristics of economic security as countermeasures resistance to internal and external threats, economic independence, self-reproduction and self-development, national interests, can be supported and protected in cyberspace Proposals for creating an effective system of cybersecurity state regulation and conditions for online information exchange within «public authorities – private sector – civil society», triangle, optimization of staffing cyber protection, development of the system of economic indicators of cyberspace functioning are introduced. Emphasis is placed on the research prospects concerning the stimulation of innovative activity aimed at the creation of effective organizational and technological model of the national cybersecurity system, the implementation of human resources, optimization of domestic legislation.

Abstract. The development of the world economy, despite the barriers, is quite dynamic. The drivers of growth and stabilization of national economies at present are not raw materials industries, nor even industrial enterprises, but companies that generate innovative products. The enterprises that are most dynamically developing and producing innovations include enterprises in the field of medicine and IT. The updated list of S&P 500 companies showed that 50% of all the most innovative companies in the world are registered in the United States. Despite the pandemic challenges, some economies have not suffered significant losses due to quarantine restrictions. Since the level of innovative development of the national economy is a total (integrated) expression of the whole complex of innovative products created by companies of such a country, the initial elements are the creation of favorable regulatory and state support for developers of innovative products, tax benefits and incentives, export support for innovative products and so on. In order to assess these achievements, international organizations have developed appropriate methods for measuring the index of innovation development, namely: Global Innovation Index (GII) (WIPO and Cornell University), Bloomberg Innovation Index (BII) (Bloomberg), Global Competitiveness Index (World Economic Forum), World Competitiveness Index (IMD World Competitiveness Center). Studies have shown that against the background of the flagship countries (Switzerland, Sweden, Singapore, USA, Germany, China, etc.), Ukraine is constantly losing its position in the rankings, which is an objective reason for deindustrialization of the economy and denationalization and privatization of strategic enterprises of national importance. Today, Ukraine ranks 45th (GII) and 56th (BII), respectively, and belongs to the group of countries with below-average incomes per capita. At the same time, Ukraine ranks 71st in terms of innovation spending and 37th in terms of innovation development (profit). The development of Ukraine’s innovation component, according to experts and specialists, is ahead of forecast values. Keywords: national economy, innovations, innovative development, innovative products, innovative companies, indices of innovative development, gross national income per capita.
