Main problem: in the history of mankind there are many examples when the question of national interests remains unresolved. The category of "national interest" has firmly entered the modern political and scientific spheres of all countries of the world. Regardless of the level and nature of development, any country has certain national interests on which it should focus. Undoubtedly, these are economic interests. Future populations, whose state and national goals are not clearly defined, may be unplanned and fragmented. Consequently, it may be violently imposed on a foreign socio-political structure. Historical experience shows that the staging of specific problems can have a negative impact on the application and implementation of the necessary measures to prevent possible mistakes, to strengthen the security of the country. In order to make this article complete and exhaustive, it is necessary to pay attention to the concept of "concept", which reflects the active attitude of people to the surrounding world as the most important category. Purpose: The purpose of the study is to analyze the concept of economic security as a state-legal institution in the Republic of Kazakhstan. Methods: The following methods are used in the article: comparative-legal, system-structural, as well as the method of systematic analysis of needs. Results and their significance: Necessity, personal interests are one of the key links in the study of the essence of the social state. After all, the rule of law in its norms must express the social interests of man in life. These categories are intended to identify the indirect causes of social actions that lead to changes and additions in various spheres of public life. Every country has its own attractions. Interests are different. And the social group, and the team, and the individual combine their actions with their interests. Man interacts with it through its goal, which determines the interests of the environment. Therefore, at the level of common consciousness, a great value of interest is determined by individual actions and actions of people, as well as by mass historical events and phenomena. By looking at this issue in detail and analyzing its basic principles, we define the concept of economic interest. In order to ensure the economic security of Kazakhstan, it is necessary to rely on its own scientific and technological development, human and natural resources, that is, to decide on management in favor of domestic producers and ensure capital investment in priority sectors of the economy.
