First, the growth rate of health is modeled taking into account a number of parameters – the service life of health, their profitability, depreciation rate, the share of profits used to capitalize health. For rates the equation which is not solved analytically, and only by numerical iterative methods is received.In the second stage of research, the structure of production assets by shares of fixed and current in their total amount is taken into account. The corresponding equation is obtained, but more complex, to determine the growth rate of all production assets. A formula is developed for an approximate determination of the growth rate of production assets, taking into account their structure and a number of resource parameters.An equation is also being developed to determine the growth rate in the variant of innovative equipment upgrade with a change in return on assets. Relevant conclusions are made on the qualitative and quantitative characteristics of trends in the dynamics of the innovation process. All analytical results are interpreted on concrete numerical examples, in particular, it concerns both models for rates, and the received approximate results of the decision of the corresponding equations.A study was conducted on the share of investments in their total amount, which is aimed at increasing fixed assets, rather than replacing the disposal of fixed assets. An appropriate formula for calculating this fraction is proposed. This takes into account the growth rate of fixed assets and their service life. Analytical analysis, as well as numerical, showed that for higher rates and service life of fixed assets is greater. It is concluded that the economic practice of updating fixed assets to some extent justifiably focuses on longer service life of equipment, including in comparison with regulatory deadlines. The transition to innovative development will necessarily lead over time to the feasibility of reducing the time of use of equipment in the manufacturing sector. For all the developed dependencies, the corresponding numerical calculations are given, which confirm the logic and practice of real interdependencies that take place in the production activities of enterprises ER -
