The object of the research is public institutions, which activities create certain conditions for improving the positive dynamics of economic relations in the regions, especially in Donetsk and Luhansk regions (Ukraine). The choice of the object is due to the high level of social tension and low level of public confidence in the authorities at all levels of public administration. Therefore, there is an objective need to study the peculiarities of the formation of civil society at the present stage of Ukraine's development, namely, institutions that implement the process of participation of the population in making current decisions on solving the problems of regional socio-economic development in the country. During the study, using methods of analysis and synthesis, analogy and comparison, as well as the method of formalization: it was proposed a step-by-step algorithm for the analysis of activities and public institutions operating at the regional and local level; it was reviewed the basic documents, normative-legal and regulatory acts which are regulating the activities of structures designed to implement public participation procedures in the formation and implementation of state, regional socio-economic policy, and addressing issues of local importance. In addition, in the course of research, the current situation regarding the activities of the investigated institutions is analyzed on the example of the Luhansk region. It has been identified that only one of the two identified types of organizations that are called to implement a mechanism for interaction between government, business and population is available. For today, the functioning of these structures is considered purely in the area of public administration. Effectiveness and economic efficiency of their activities are practically not carried out. Taking into account the identified shortcomings, duplication of functions and ineffective activities of existing public institutions, it is proposed to reorganize them and create one structure based on existing ones. This structure is intended to unite all participants of the social dialogue in order to form effective partnership relations and conduct positive reforms in the sphere regional socio-economic development, and the successful regulation of economic relations between the regions and the state.
