It is established that the activity of industrial enterprises in conditions of instability of the economic situation in the country, political situation, deterioration of the welfare of the population, imperfection of the current legislation, increase of tax pressure, that is external factors of activity, is aimed at strengthening of competitive positions by penetration a new market segment, production of innovative products, reduction of costs, rational use of resources, under the condition of implementation of technological advances.
It is determined that the level of innovation activity of enterprises is characterized by a gradual deterioration, since scientific and technological achievements are rather slowly used, manufactured products, based on the use of innovative developments, are not in demand on the foreign market, because it is uncompetitive along with the products of leading enterprises. It is substantiated that there are no favorable conditions for rising the innovation activity of industrial enterprises, since most of them are in crisis or unprofitable, not provided with sources of financing for attracting innovative technologies, sharing experience with international organizations. It is proved that the solution of these problems is the implementation of the innovation policy of industrial enterprises, which is possible under the conditions of formation and use
of economic mechanism of innovation activity (EMIA). Elements of organizational and economic mechanism of innovative activity and innovative development of industrial enterprises are proposed under condition of formation of innovation policy.

In the practice of repairing the machines in agriculture, the following strategies are mainly applied: forced repairs; conducting repairs in plan order and a combined strategy with elements of both strategies.
An investigation was carried out and analytical dependencies were obtained to determine the function of the recovery (characteristic of the failure flow) of the machine components in the forced repairs (after failure), to carry out repairs in a planned order and a combined strategy with elements of the first two strategies to calculate the required pool of spare parts to maintain machine performance.
