Resumen
Introduction. Implementation of program projects of social and economic development of the territories of Ukraine is inefficient, with overspending of the budget and completion not at the set time. This is due to the use of reactive project management methodologies that do not take into account the complexity of project implementation, the turbulence of the project environment. The lack of hybrid mechanisms for managing project programs of socio-economic development of territories based on the convergence of different methods of project management is an unresolved problem. The implementation of socio-economic development project programs is carried out using the mechanisms of financial regulation of territories on the basis of the "recipient-donor" model. Therefore, the development of mechanisms for hybrid management of project programs of socio-economic development of territorial systems based on the convergence of key methods of project management is an urgent scientific task. Purpose. The purpose of the work is to develop mechanisms for hybrid management of program projects of socio-economic development of the regions of Ukraine using the tools of financial regulation, public-private partnership and convergence of these mechanisms. Methods. The methods of hybridization and convergence of project management methodologies are used in the article. Results. Based on research, it is proved that the implementation of program projects of socio-economic development of territories requires the use of various components of project management through hybridization and convergence. The terminological base of project management has been expanded by introducing new definitions "hybrid project management of socio-economic development projects", "convergence of project management mechanisms". Processes of management of program projects of social and economic development of territories, on the basis of model "recipient-donor" are formalized. Conclusion. The analysis of current trends in the implementation of complex programs of socio-economic development projects has shown the ineffectiveness of existing project management methodologies associated with the lack of mechanisms for hybrid project management based on convergence of best practices in project management projects. A convergent model of hybrid management of projects of socio-economic development of territories by means of identification of the main challenges and problems in the life cycle of the regional system is developed, which takes into account indicators of project success in the program based on analysis of project management best practices.
