The article is devoted to the study of the peculiarities of the application of public-private partnership (PPP) mechanisms in regions with low financial stability. The group of constituent entities of the Russian Federation in various federal districts with relatively low rates of gross regional product and a fairly high share of gratuitous receipts in the revenue side of the budget is selected for the study: Republic of Mordovia, Republic of Tuva, Zabaykalsky Krai, Pskov Oblast, Oryol Oblast, Jewish Autonomous Oblast. The evaluation of the effectiveness of the use of PPP tools in this group of regions in comparison with other subjects of the Russian Federation is carried out, the current regulatory framework regulating PPP in them is analyzed, as a result of which the key problems inherent in such territories are identified. Based on the best regional practices, a set of measures and adjustments to the regulatory framework aimed at improving the efficiency of using the PPP mechanism in regions with low financial stability is proposed.

The purpose of the work is to develop a mechanism for increasing the socio-economic development sustainability of the region based on the application of modern GIS technologies. The subject of this work is the organizational and economic relations that arise in the process of constructing a geoinformation system for modeling the spatial development of territories. This system is aimed at achieving sustainable economic growth in the region. The methods of empirical research (observation, comparison, collection and study of information), methods of current and prospective analysis and theoretical and practical material synthesis were used in the work. The article analyzes the available publications on the issues of regional sustainable development, which allowed to conclude of necessity to introduce modern geoinformation systems for the operational collection, processing and analysis of primary information on indicators of socio-economic development of the territories. The developed mechanism for increasing the sustainability of the socio-economic development of the region using geo-information systems includes three conceptual blocks: creation and functioning of a regional GIS-center with constant fi of databases and updating of operating systems; geoinformation system of macroeconomic and spatial territory development data analysis; modeling of regional development taking into account individual features of the territory and targets for sustainable socio-economic development. This mechanism is designed to increase the stability of the socio-economic development of the region, by taking into consideration the balance of interests of the state, business and society. This will ensure a non-decreasing rate of opportunity growth to meet the needs of present and future generations who live in the given territory and the preservation of the environment. The proposed mechanism for increasing the stability of spatial development of regions on the basis of geoinfrational technologies is a tool for improving the management system in the framework of implementing the state and regional economic policy of spatial development of Russia. The use of geoinformation systems in the development of measures to increase the sustainable socio-economic development of the region contributes to improving the quality of the complex system state analysis. It contributes to the solution of practical problems in allocating resources or analyzing the effectiveness of their deployment. It also contributes to the implementation of the strategic planning principles using digital technologies and to ensure the timeliness of the decisions made in the field under investigation.
