Shterndok E. Modelling the impact of spatial factors on the valuation and use of megapolis land

The dissertation deals with the solution of the vital scientific problem in improving the effectiveness of valuation and use of megapolis land by modelling the impact of spatial factors on land use. The functional lines of urban land allocation were identified. The basic functional line in land allocation in the city of Kharkiv was found to be housing development with a predicted growth indicator. To ensure the territorial development of a megapolis, the focus is on high-rise apartment building development. This involves challenging issues related to unjustified use of territories beyond city limits, a low land use level with account of existing site development, and a degrading effectiveness of interaction among land users, landowners and state authority bodies. The theoretical concepts are systemised and the spatial factors influencing the valuation of megapolis land use are determined. A classification was suggested for models of spatial factors pertaining to the levels of their impact, appurtenance, and composition of variables and origin. This classification enabled identifying their properties for modelling the impact of spatial factors on land valuation and use. The trends in the formation and realisation of urban land relations are established. A structural-and-logic scheme for modelling the impact of spatial factors on the monetary valuation of megapolis land was developed. The factors were modelled by applying geoinformation support at the zonal, local and actual land lot levels. An approach was suggested to model the impact of spatial factors based on geoinformation support at the zonal, local and actual land lot levels, and on correlation-and-regression analysis. This enabled formalising the spatial dependence and improving the validity of monetary valuation of megapolis land. A scheme was developed for modelling the impact of spatial factors on the use of megapolis land. It is based on a developed multilevel system of indicators, suggested expert appraisal methods, hierarchy analysis, and local and integrated models. This enabled establishing the integral spatial criterion for elaborating methodical recommendations on improving land use effectiveness. Methodical recommendations were worked out to improve the effectiveness of megapolis land valuation and use. They are based on the results of using geoinformation support, determining the integral spatial criterion, and on established relations between this indicator and the level of land valuation in Ukraine regions. The recommendations enabled developing an information basis for monetary valuation at the zonal, local and actual land lot levels, and improving the effectiveness of interaction of spatial factors.
