AS A COMPONENT OF NATIONAL SECURITY Abstract. At the current stage of social and economic development the issues of the national security and its public and legal regulation, both externally and internally, are becoming more urgent. The national security supports the very existence and development of man, society and state. And the balanced state policy as well as the efficient legal regulation plays an important role in this process. The fundamental principles of the legal and regulatory environment in Ukraine are defined by the Constitution of Ukraine, the Law of Ukraine on National Security, and other legal-regulatory and international acts. And the most significant component of the national security is the economic security influencing all life spheres of a person and the whole society. The economic security is the basis of economically effective state and a necessary condition for its sustainable development. The economic security is provided at the national and international levels. At present the economic security is primarily defined by internal threats, such as uneven economic development of some territories, decline in certain industries, low living standards, etc. The analysis of the social and economic state of Ukraine clearly demonstrates that reasons for threats to the economic security of the country are of a regional nature. The appropriate level of security can be maintained by a complex system of measures aimed at improving macroeconomic performance of the country, which positively influences the local social and economic systems. An appropriate level of the economic security can be reached by implementing a system of organizational and legal measures, including economic, legal, organizational and managerial, which are enforced by competent authorities and local governments by means of various forms and methods of the state legal regulation in order to ensure rights of man and citizen, improve the living standards, and achieve sustainable development of the state. Keywords: economic security, national security, public and legal regulation, food safety, sustainable development. JEL Classification F52 Formulas: 0; fig.: 2; tabl.: 0; bibl.: 19.
