Problem setting. In Ukraine, state support for small businesses was introduced in 2000. Currently, the mechanism of state support of economic entities is regulated by a number of acts of national legislation. However, the place of the legal institution of state support in the system of economic law, its relationship with state aid, the criteria for the admissibility of state aid in the context of the unification of national legislation with EU legislation continue to remain debatable in the science of economic law. Analysis of recent researches and publications. Economic and legal problems of small and medium-sized enterprises and their state support were studied by many domestic and foreign scientists. Only recently, these issues were considered in the collective monograph of the Research Institute of Legal Support of Innovative Development of the National Academy of Sciences, the monograph of D.S. Korytin, who studied the legal regulation of the economic activity of small and medium-sized enterprises, the dissertations of Feofanova I.M., who considered the economic and legal aspect of the admissibility of state aid and Petrova N.O., who studied the administrative and legal principles of monitoring state aid sub economic entities in Ukraine. Purpose of the research is to determine the place of the institute of state support of small and medium-sized enterprises in the system of economic law of Ukraine. Аrticle’s main body. Small and medium-sized enterprises play a significant role in the world economy. However, the operating conditions of small and medium-sized enterprises in Ukraine are difficult. Obstacles are the imperfection and burdensomeness of the taxation system, the presence of administrative obstacles, unsettled issues of financing and lending, low level of state financial support, underdeveloped infrastructure supporting entrepreneurship, etc. Currently, to these reasons added the negative consequences of Russia’s full-scale aggression. Such an effective tool as state support helps small and medium-sized enterprises overcome the consequences of the war and develop their activities in the post-war period. Therefore, strengthening the state support for small and mediumsized enterprises and improving the mechanism of its provision is an extremely urgent issue for our state The activity of small and medium-sized enterprises is very important for the economy of Ukraine. In wartime, their effective activity contributes to increasing budget revenues and reducing unemployment, and in the post-war period should become the very lever that will accelerate the growth of the economy and the reconstruction of the country. However, the Economic Code of Ukraine contains regulations on state support and protection of all economic entities. and support of small and medium-sized enterprises is not the state’s priorities Conclusions and prospects for the development Small and medium-sized enterprises play a significant role in the economy of Ukraine. In wartime, their effective activity contributes to the increase of revenues to the budget and the reduction of unemployment, and in the postwar period, it should become the very lever that will accelerate the growth of the economy and the reconstruction of the country. On the other hand, the priority of state policy regarding the support and development of small and medium-sized enterprises is not fixed in the Economic Code of Ukraine, which needs to be corrected. The list of means of state regulation of economic activity contained in Article 12 of the Economic Code of Ukraine should be supplemented by such an institution of economic law as state support for small and medium-sized enterprises.
