The interdependent relations between economic growth and structural changes exist in the economy. While economic growth can be measured with one aggregate macroeconomic indicator such as gross domestic product or gross national product, in the area of the structural changes the measurement is more complex. The dynamics and intensity of the structural changes in the economy or their influence on the individual factors of economic growth cannot be measured by one indicator or by one paradigm. Many different approaches and methods of measurement and quantification of the structural changes exist in economics. In this article we tried to fixate on some of them: the index of specialization of sectors, index of concentration of industries, measurement of the intensity of the structural changes and the indicators of influence of the structural changes on the growth of labour productivity.
