Abstract: That article is devoted to clarifying the theoretical vision of the economic cyclicality under the conditions of economic systems post-industrial transformation. In particular, taking into account the impact of post-industrial transformations (The increasing in the share of intangible production in gross value added and an increasing of the weight of intangible assets in gross capital formation were used as the indicators of such transformations) on the characteristics of economic systems, which are in focus of institutional theories (in particular the size of transactional costs, the costs and duration, inherent to processes of «imitation of leaders», the strength of motives and incentives for entrepreneurs’ innovation activities). It is substantiated that the reduction of the impact force, which the reproduction of physical capital has on the formation of cyclical impulses does not require an absolute reduction in the capital intensity of the national product (which is not observed in developed countries), but relative. This means that even with increasing capital intensity of output, the weight of physical capital may decrease due to the fact that information or scientific capacity of products grows faster, so the share of physical capital in the new value structure is reduced. It is also determined that since intangible assets are not subject to physical wear and tear, and are replaced only as they age, the intensity of its using does not affect the rate of capital depreciation. This property of intangible assets helps to limit the amplitude of cyclical fluctuations, i.e. acts as a «built-in stabilizer», in contrast to the mechanisms of reproduction of physical capital, which contributed to the increase in the amplitude of cyclical fluctuations.
