The algorithm of determination of priorities of target investment of territorial-industrial complex of Donetsk People's Republic on the basis of solution of optimization problem of maximization of utility function on balanced distribution of target investments between the main branches of industry of the region is developed and substantiated. The proposed algorithm will allow to improve the methodology of distribution of public-private investments in the sphere of territorial-industrial complex, to substantiate the expediency of determining the equilibrium state in the dynamics of interaction of industries. The author's solution is based on the dynamic model of inter-sectoral balance, utility function and optimization problem on its maximization on the set of admissible alternatives (priority levels of target investment) for one of two reasonable scenarios of economic development: recovery strategy or development strategy. The universality of the algorithm lies in the choice of the development scenario depending on the goal of managerial decision-making, which corresponds to the strategy of socio-economic development of the object and the state policy in this direction through the redistribution of investment flows of the territorial-industrial complex.
