It has been proven that the transformational processes taking place in Ukraine are related to the deepening of crisis phenomena in the economic sphere, the slowdown of the main indicators of regional development, the impact of the consequences of the COVID-19 pandemic, and military operations. In such conditions, it is necessary to rethink approaches to ensure the efficiency of the functioning of regions by improving the system of land resources management, as the main factors of their development. At the same time, the modern European experience of land administration and information provision of the formation and use of real estate based on the application of the multi-purpose cadastre is considered. The aim of this work – to develop scientifically based recommendations for the formation of a multi-purpose cadastre at the regional level. To achieve the goal, the following tasks were completed: determination of the multi-purpose cadastre at the regional level; identification of factors affecting the formation of a multi-purpose cadastre; presentation of the results of mathematical modelling of the factors of formation of the multi-purpose cadastre; the formation of geo-information support of a multi-purpose cadastre. Method. To obtain research results, special methods are used: structural and content analysis - to form a conceptual apparatus for defining a multi-purpose cadastre at the regional level; analytical and methods of expert analysis - to determine the spatial, urban planning, investment and environmental factors of the information support of the multi-purpose cadastre; analysis of hierarchies - to determine the weighting factors characterizing the mutual influence of indicators of information provision of the multi-purpose cadastre; mathematical modelling - for the development of models that determine the impact of spatial, urban planning, investment and environmental factors on the integral indicator of information provision of the multi-purpose cadastre; correlation-regression analysis - to establish the influence of the integral indicator of information provision of the multi-purpose cadastre at the regional level on the gross regional product; of geo-information analysis - for the development of geo-information support of the multi-purpose cadastre. Scientific novelty and practical significance. An integral indicator for assessing the level of information provision of the multi-purpose cadastre is proposed, which is determined based on spatial, urban planning, investment and environmental factors, which allows forming the information basis for the development of scientifically based recommendations for the creation and implementation of the multi-purpose cadastre at the regional level. The concept of "multi-purpose cadastre at the regional level" was defined, which considers the totality of spatial, urban planning, investment and environmental support, which allowed to build a multi-level information system for the formation of a quantitative basis of real estate management at the regional level. The method of integral assessment of the level of information support of the multi-purpose cadastre at the regional level is characterized, which is based on a multi-level system of factors, methods of assessment of analytical and qualitative indicators, analysis of hierarchies, local, generalizing and integral models, which made it possible to carry out mathematical modelling of these factors, to form geo-information support for adoption reasoned decisions in the field of real estate management. The results of mathematical modelling of the processes of development of information support of a multi-purpose cadastre based on the establishment of relationships between system factors and an integral indicator by applying the method of correlation-regression analysis are presented, which makes it possible to build predictive models and establish trends in the formation and use of real estate at the regional level, taking into account the spatial, urban planning, investment and environmental support. Scientifically based recommendations for the development and implementation of a multi-purpose cadastre were proposed based on the results of their level assessment and modelling, which made it possible to single out directions for increasing the level of information provision and application of the multi-purpose cadastre for increasing the efficiency of real estate use at the regional level [Ноlovachov et al., 2022; Ноlovachov, 2022].
