The tax and customs privileges provided to industrial parks in different countries of the world are defined. The legal aspects of creation and functioning of industrial parks in Ukraine are analyzed. The main barriers that hinder the formation and localization of industrial parks at the level of united territorial communities have been identified. The structural and logical scheme of the concept of creation and functioning of industrial parks in Ukraine is constructed. Regional development strategies for 2021-2027 are considered. Based on the analysis, it is established that in a significant number of strategic documents the priority areas include accelerating the achievement of competitiveness and innovation of the region’s economy on the basis of smart specialization.
