Abstract
Introduction. In the face of structural shocks, traditional econometric methods lose their effectiveness in forecasting regional economies, especially when working with short time series. The objective of this study is to develop a methodology for analyzing and forecasting short-term regional dynamics based on neural network modeling, adapted to the specifics of regional statistics.
Materials and Methods. The empirical base consisted of annual Rosstat data for the Trans-Baikal Territory for 2003–2022, representative of resource-rich territories of the Russian Federation. Recurrent neural networks with LSTM architecture were used. The author's approach includes assessing the systemic significance of indicators using a composite index and comparing training sample generation strategies (sliding and expanding windows).
Results. The differential effectiveness of forecasting methods for different types of indicators was revealed. The expanding window method demonstrated high accuracy for indicators with stable trends (gross regional product forecast error of approximately 0.3 % in 2020–2021), while the sliding window method was more effective for volatile indicators. The developed toolkit for analyzing the systemic significance of indicators revealed a stable cluster structure of the regional economy, including production-investment and socio-demographic clusters. Verification of the models confirmed their resilience to typical fluctuations but demonstrated fundamental limitations under the unprecedented geopolitical shocks of 2022.
Conclusion. The practical significance of this study lies in the development of a comprehensive toolkit for improving the effectiveness of regional economic planning and forecasting in the face of structural change. The material may be useful in the activities of regional government and strategic planning bodies.
