The article examines the challenges of enhancing capital productivity in the regions of Ukraine under wartime conditions, emphasizing it as one of the key drivers of territorial economic resilience. It notes that the intensification of investments aimed at modernizing production capacities, developing social and transport infrastructure, as well as rebuilding industrial facilities, significantly improves the efficiency of capital utilization and contributes to the creation of conditions for sustainable economic growth. The concept of a driver of regional capital productivity growth is defined as a key factor that stimulates the more efficient use of capital and increases its overall return. Based on an expert survey, the regional specifics of innovation activity in Ukraine’s regions during the war are examined, and its role in enhancing the productive capacity of the regions is determined. The dynamics of capital investments in regional economies are analyzed. The specifics of the activities of the main groups of investors in the regions are considered, and the priority areas for investment are identified and assessed. A covariation between the number of key types of investors and the number of selected priority investment areas, as well as the adaptability of regional policy under wartime conditions, are determined and explained in the context of the interaction between regional authorities and investors. Analysis of investment activity in Ukraine’s regions during the war shows that regional investment activity under such conditions is a critical factor influencing not only the short-term survival of regional economies but also the foundation for their recovery and long-term development. The analysis reveals significant differences across regions depending on their geographical location, level of economic development, and direct exposure to military threats. The authors conclude that increasing investment activity during wartime is a key driver that can preserve and enhance capital productivity in Ukraine’s regions, laying the groundwork for sustainable economic growth in the post-war period. Through systemic efforts of the state, international support, and adaptive measures to assist businesses, it is possible to achieve stable growth and economic recovery, which will subsequently form the basis for Ukraine’s integration into global economic processes and structures.
