High adaptability of the used models confirms probability to make a choice of the best strategy of development of the state taking into account the construction potential in particular regions in Ukraine. The scientific value of the research lies in the use of dynamic models of the system to study the relationships of the elements of the micro and mezolevel subsystems. The forecast models reflect the value of the state regulatory policy in developing strategic priorities for economic growth.

Introduction Modern economic conditions in a period of significant macroeconomic imbalances and accumulated problems against the background of the spread consequences of financial and economic, banking and political instability require intensifying the development of dominant economic sectors. At the same time, improving the population living standards and the competitiveness of economic entities depend on the dynamics of development within fund-forming industries. At different stages in the development of economics, researchers on macroeconomic phenomena and processes in their work have noted the significant participation of construction sector in the expanded reproduction. Despite the significant impact on the economic security of the state, and due to the violation of key goals and strategic priorities of its operation, the construction sector, becomes a significant risk in source presenting on socio- economic threats for future periods, which are manifested through the prism of social, economic, institutional, technological and environmental aspects. It should be noted that construction companies, as well as the economy of Ukraine as a whole, face long-term systemic challenges that reflect both global trends and national obstacles on the way to
