Military actions on the territory of Ukraine have had massive negative consequences. To address these issues, the efforts of state and local authorities, scientists, and businesses have been united. In connection with the adoption of Law of Ukraine No. 5323 dated July 9, 2022, titled "On Amendments to Certain Legislative Acts of Ukraine on the Fundamentals of the State Regional Policy and the Policy of Restoration of Regions and Territories," Ukrainian scientists were tasked with finding mechanisms for the effective restoration of territories of various functional types. The article presents the results of theoretical and empirical studies, which led to the conclusion that it is realistic to achieve effective restoration of Ukraine's territories after the current war by introducing special economic and investment regimes that also serve as incentives for sustainable development. A theoretical review of the instruments for financing Ukraine's restoration allowed us to highlight their differences. The European and Japanese experience of recovery after military conflicts has enabled us to propose acceptable approaches to rebuilding Ukraine. The survey helped determine the commencement dates and priorities for the restoration of these territories. Using this data, a concept of sustainable development for the territories was formulated, represented by a cognitive model of sustainable development post-war. Additionally, a list of benefits provided to investors on priority development areas, along with a scheme for reconciling interests between the state, investors, and territorial communities, has been established.
