This paper presents a model of innovation diffusion based on physical approaches, describing stages of accelerating and decelerating growth. An exponential growth is described using a diffusion model, while a logarithmic one employs an electrical engineering model. The paper presents the correspondence of physical parameters with their economic counterpart: size of a company; characteristic of speed of information exchange between firms; company’s willingness to innovate; inter-firm influence and the breakthrough level of innovation. The theoretical model obtained was tested on historical data of innovation implementation in the fuel and energy complex, followed by adjustments of coefficients depending on the branch of innovation implementation. The developed model is applicable for describing the process of innovation dissemination in any industry in the country, as well as for investment and business planning in companies and decision-making on investments in innovation projects. When applied in industries with low levels of innovation activity, an increase in the level of high-tech production and the share of organizations implementing technological innovations is predicted. Using the example of Russia’s fuel and energy sector, rising in the technological level of enterprises and a decrease in import dependence are forecasted.</p></abstract><trans-abstract xml:lang="ru"><p>Анализ и оценка эффективности инноваций требует развития инструментов моделирования процесса их распространения в отрасли. В данной работе представлена модель распространения инноваций, основанная на физических подходах и описывающая стадии ускоряющегося и замедляющегося роста. Для описания экспоненциального роста используется диффузионная модель, а для логарифмического — электротехническая модель. В работе представлено соответствие физических параметров их экономическим аналогам: размер компании, характеристика скорости обмена информации между фирмами, готовность компании к внедрению инновации, межфирменное влияние и прорывной уровень инновации. Полученная теоретическая модель протестирована на исторических данных внедрения инноваций в топливно-энергетическом комплексе с последующей корректировкой коэффициентов, зависящих от региона внедрения инновации. Разработанная модель применима для описания процесса распространения инноваций в любой отрасли страны, а также при инвестиционном и бизнес-планировании в компаниях и принятии решений об инвестировании в инновационные проекты. При применении данного инструмента в отраслях с низким уровнем инновационной активности прогнозируется повышение уровня высокотехнологического производства и доли организаций, осуществляющих технологичные инновации. На примере топливно-энергетической отрасли России прогнозируется повышение технологичности предприятий и снижение уровня импортозависимости.</p></trans-abstract><kwd-group xml:lang="en"><kwd>technological development</kwd><kwd>innovations</kwd><kwd>innovation management</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>технологическое развитие</kwd><kwd>инновации</kwd><kwd>управление инновациями</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Голышева Е.
