Институциональные модели развития системы земельных отношений в сельском хозяйстве | Institutional models for the development of land relationship system in agriculture

الروسية. The purpose of the work is to build models for the development of the system of land relations (LR) in agriculture. The task of the research was to substantiate the methods, techniques, methods, tools that ensure the consistent construction of functional and structural institutional models. A modular-trigger system is proposed that allows implementing a multicriteria approach to assessing the use of lands from agricultural land by affiliation, types, and compliance with land legislation. Ineffective participants in land relations, lack of clarity in the implementation of control, incentive measures, the need to create a single governing body were identified based on the materials of the activities of agricultural organizations (AO) of the Saratov region for 2015–2019. The functional institutional model of the development of the system of LR in agriculture includes subjects, a verifier, a management core, describes direct and feedback links between elements, is focused on obtaining structured information about the current situation and trends in land use, electronic interaction between government authorities and AO. The structural institutional model is supplemented by the interaction of subdivisions of the Department of Land Relations in Agriculture at the regional and district levels with the territorial bodies and departments of the Ministry of Agriculture, Rosprirodnadzor, Rosselkhoznadzor, Rosstat, and Rosreestr. The calculation of the coefficient of economic efficiency is formalized as the ratio of the number of effective agricultural land users to their total number, the scope of its variation is established with the specification of each range. According to the results of the analysis of land use of agricultural organizations in the Saratov region, the least effective micro zone was determined – the Zapadnaya one. The practical significance lies in assessing the predictive efficiency of the core of the model for the development of the system of LR in agriculture. In the Saratov region, the coefficient of agricultural land use efficiency can be 0.24 (an acceptable level).
