This study seeks to improve non-survey regionalization techniques to better capture regional and local sectoral specializations and to produce more accurate sectoral multipliers for subnational development planning. The hypothesis is that a symmetrical and unrestricted use of the simple location quotient (SLQ), as part of the adjusted Flegg’s location quotient (aFLQ), such as the proposed KFLQ variation, can provide a more reliable database for modelling regional development. Under this approach, regional and local coefficients are allowed to surpass national averages. For the empirical analysis, the productive network of the West Greece region was simulated. Weighted and non-weighted type I backward sectoral employment multipliers were estimated to illustrate the differences resulting from the application of various regionalization techniques. The hypothesis was tested using the assumption that the parameter δ should be set so that KFLQ approaches 1 when the regional-to-national size of a sector approaches its average national allocation across regions. For SLQ, this occurs for each sectoral indicator at approximately 1.5. This assumption resolves the problem of the previously arbitrary definition of the exponent δ. </p></abstract><abstract xml:lang="ru"><p>В большинстве стран при разработке стратегий развития в части анализа производственных сетей сталкиваются с нехваткой первичных региональных и локальных данных «затраты–выпуск». Чтобы решить эту проблему, ученые на протяжении десятилетий занимаются разработкой безопросных методов для вторичного определения региональных и локальных межотраслевых коэффициентов прямых затрат, которые используются для оценки отраслевых мультипликаторов. Настоящее исследование сосредоточено на совершенствовании безопросных техник регионализации с учетом отраслевой специализации регионов и более точном расчете мультипликаторов для планирования развития на региональном и локальном уровне. Гипотеза исследования заключается в том, что симметричное и свободное от ограничений использование простого коэффициента локализации (SLQ) как части скорректированного коэффициента локализации Флегга (aFLQ), например, в предлагаемой вариации KFLQ, позволяет получить более надежную базу данных для моделирования региональных процессов развития. В этом случае действует принцип, согласно которому региональные и локальные межотраслевые коэффициенты прямых затрат могут превышать средние национальные значения для соответствующих отраслей. Для эмпирического анализа была смоделирована производственная сеть региона Западная Греция. Для демонстрации различий между методами регионализации были рассчитаны обратные мультипликаторы занятости типа I во взвешенном и невзвешенном вариантах по отраслям. Проверка гипотезы проводилась с учетом допущения, что параметр δ определяется таким образом, чтобы KFLQ стремился к 1, когда соотношение размеров отрасли в регионе и на национальном уровне приближается к среднему отраслевому распределению по всем регионам. Для SLQ это соответствует каждому отраслевому показателю примерно при значении 1,5. Такое допущение решает проблему произвольного выбора показателя δ в существующих методах.</p></abstract><kwd-group xml:lang="en"><kwd>Regional input-output analysis</kwd><kwd>non-survey techniques</kwd><kwd>logarithmic Flegg’s location quotients</kwd><kwd>KFLQ variation</kwd><kwd>West Greece region</kwd><kwd>employment</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>анализ региональных таблиц «затраты-выпуск»</kwd><kwd>безопросные методы</kwd><kwd>логарифмический коэффициент локализации Флегга</kwd><kwd>вариация KFLQ</kwd><kwd>Западная Греция</kwd><kwd>занятость</kwd></kwd-group></article-meta></front><body/><back><ref-list><ref id="ref1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Azorín, J.
