摘要：The paper off ers answers to one of the typical problems of economic theory – how it is practically possible to measure and interpret the quality of economic time series at all economic levels. At the macroeconomic level, the task is solved by weighted geometric aggregation of input factors (labor and capital) into a summary input factor (SIF) – the method is similar to the Cobb-Douglas production function. Th e paper shows differences between our approach and the approach of growth accounting – our approach is based on more general conditions and covers not only situations of growth of economic indicators but also situations of their decline or stagnation. The approach also allows for distinguishing the compensation of input factors. Th erefore, the methodology presented in the paper can be used in many practical applications; for instance, it enables us to clearly calculate intensive and extensive parameters of economic growth
