      <abstract xml:lang="ru">
        <p>Зависимость фондоотдачи от длительности эксплуатации горных пред­приятий исследована недостаточно. Определение ее позволило бы более обос­нованно планировать фондоотдачу с учетом возрастных характеристик пред­приятий, а наличие количественных оценок, характеризующих связь «фондо­отдача - возраст предприятия», способствовало бы повышению уровня отрас­левого прогнозирования фондоотдачи ...</p>

        <p>The dependence of stock return on the duration of operation of mining enterprises is not sufficiently investigated. Determining it would allow more reasonable planning of stock return, taking into account the age characteristics of enterprises, and the availability of quantitative estimates that characterize the relationship “stock return - age of the enterprise”, would contribute to improving the level of sectoral forecasting of stock return ...</p>
