The issues of restoration and development of living conditions in post-conflict territories through the application of the concept of “SMART-city” are highlighted. The effectiveness of the SMART approach to local governance and the promotion of dynamic urban development has been proven. To determine the feasibility of applying the development of the concept of “SMART-city” to the tasks of restoration and development of Donetsk and Luhansk regions, the problematic issues and conditions in which their life processes take place are highlighted. A schematic representation of the logical interrelationships of the structural elements of the concept of Smart city of directions of restoration, development of spheres of life of cities in post-conflict territories is presented. It was determined that the concept of “SMART-city” is based on the interaction of 6 basic structural elements: smart economy, mobile access, smart environment, smart housing, progressive people, modern management, which fully ensures a guaranteed solution to the problems of restoration and development of the spheres of life of cities on post-conflict territories. It has been determined that the processes of implementation and development of the “SMART-city” concept are only gaining momentum around the world, therefore, modern strategic documents of territorial and national development should be revised in terms of integration and correlation with the principles of “SMART-cities” development. Some available mechanisms for implementing the Smart city concept are given. It is argued that the orientation of city management towards the concept of “SMART-city” will allow changing the status of territories from post-conflict and subsidized to “smart” without going through intermediate stages of recovery and development, which, on the one hand, requires much more funding, on the other, minimizes the time spent on recovery and will accelerate the receipt of future income, expand development prospects.
