One of the main strategic tasks of modernizing the territorial organization of power is the forming of effective local self-government. The key to successful implementation of the reform of local self-government and decentralization of power is the creation of united territorial communities. The effective functioning of the united territorial communities mainly depends on the financial, resource and institutional components. For Ukraine, the most acute problem is the loss of a human resource, which is actively diminishing due to the migration of labor abroad. Such a negative situation requires increased attention of local authorities to stimulation of entrepreneurship development. The article deals with the features of reforming the activities of state authorities and local self-government in the conditions of decentralization. The factors of formation of economically self-sufficient united territorial communities, in particular entrepreneurial activity, are determined. The algorithm of forming the potential of creating new united territorial communities in the Lviv region and the degree of dependence of the various factors on the basis of the regression model is constructed. The influence of lucrative enterprises and young people on the development and creation of new united territorial communities is highlighted. Therefore, stimulation of youth entrepreneurship should become a priority area for the development of the Lviv region. Among the instruments for promoting youth entrepreneurial activity, cooperation between state authorities, local self-government, educational institutions, large enterprises and financial institutions should be highlighted. It has been established that low living standards are the catalysts for the formation of new united territorial communities in the Lviv region, which make decisions to unite in new communities in order to improve the social and economic situation in their territory. Accordingly, an increase in the number of inhabitants and the expansion of the community increases the opportunities for the development of the area. The main source of filling local budgets of the community is tax revenues. In this case, the creation of new jobs, the use of existing and increased entrepreneurial potential will contribute to the successful reform of the territorial organization of power, the reduction of migration flows, and the development of infrastructure of the area. The consideration of social factors for the further research of forming of new united communities in the Lviv region is proposed.
