Assessment of the Environmental Sustainability of Regional Development Based on the Driving Forces – State – Response Model

The aim of the study is to assess the environmental sustainability of the ecosystem of the Khanty-Mansi Autonomous Okrug - Yugra (KhMAO-Yugra) for the period from 2013 to 2023 based on the Driving Forces - State - Response ( PSR ) model. The Environmental Sustainability Index (ESI) of the ecosystem under consideration was determined using the Driving Forces - State - Response model, the system of indicators of which was modified taking into account the natural and climatic features of the region. The ESI values were calculated using the TOPSIS (The Technique for Order of Preference by Similarity to Ideal Solution) method, while the weighting coefficients of the PSR model indicators, in turn, were calculated using the weighting method of their information entropy (WIE). The weighting coefficients of the model components were defined as composite indices from the VC of the corresponding indicators. The state of sustainability of the ecosystem of the region was determined according to the classification of states of sustainability of the functioning of large systems described by a fixed set of indicators. Calculated values of the IEI index show that from 2013 to 2023, the Khanty-Mansi Autonomous Okrug-Yugra ecosystem was in a "State with Signs of Instability." From 2013 to 2017, ecological resilience declined rapidly, but since 2018, it has shown steady growth, reaching a "State Near Stable." Using the PSR model and the TOPSIS method with the MVIEP allows us to identify historical trends in changes in the region's ecosystem resilience, which is important for analyzing the effectiveness of organizational and technical solutions developed by the regional administration and key actors in its economic system.
