Scientific Problems of Regional Development Assessment Methodology

The article considers systemic methodological problems in assessing regional development in the context of a modern regional economy. Based on a critical analysis of the literature review (2020–2025), the main problems were identified and grouped into four blocks: indicator-measurement (incomparability of data, subjective indicator selection, weight uncertainty, multidimensionality), spatial-statistical (ignoring spatial autocorrelation, equating differences to average values, issues of scale and digital transformation), institutional-management (the gap between strategic planning and monitoring, the formal nature of the assessment) and specialized (incompatibility of methodologies for different regions, mainly rural areas). The author’s classification of problems is proposed, which allows for a systematic discussion of ways to improve the methodological apparatus. Based on the results obtained, proposals are formulated for the development of methodological support, statistical basis and institutional environment for assessing regional development.
