This study examines total factor productivity (TFP) growth among Russian enterprises in 2018-2023 using stochastic frontier analysis (SFA) and firm-level data from the SPARK dataset (approximately 120,000 firms across major sectors). The analysis involves estimating stochastic production functions separately for 198 narrowly defined industries. This approach accounts for firm-specific inefficiency levels, capturing shortfalls relative to industry best practises (the stochastic production frontier), thereby decomposing TFP dynamics into technological progress (frontier expansion) and changes in efficiency relative to the frontier. Average annual TFP growth fluctuates between -2.4% and 3.9%, yielding approximately 5% cumulative growth over six years. Fluctuations during the 2020 COVID-19 pandemic and the 2022 sanctions shocks stemmed primarily from efficiency changes rather than frontier expansion: technological progress remained modest and stable. Although overall TFP growth remained positive in 2020, contactintensive services (accommodation and food, arts and entertainment, personal services) contracted sharply; wholesale trade and transportation drove the decline in 2021 amid lasting supply chain disruptions; nearly all sectors experienced negative growth in 2022 (except manufacturing, which accelerated); and most sectors rebounded strongly in 2023, except wholesale and retail trade. Using Rosstat input-output tables to classify industries by trade integration, the study finds that exporters were hit hardest in 2021-2022, while importers (especially in manufacturing) exhibited stable or even accelerating TFP growth, and non-traders remained stagnant.
