The functioning of the real sector of the economy in any country is based on the operation of non-current assets (such as equipment, technologies, structures) and current assets (including raw materials, finished products). The interaction of these two categories makes it possible to ensure the stable functioning of trade turnover and replenishment of the state budget.
Non-current assets have the property to wear out as they are used, both physically and mentally. The average service life of high-tech equipment, which today is the basis for reproducing what brings income to the state and wages to the real sector, is about 10 years, after which it requires updating taking into account new technologies and market needs.
Time is inexorably passing, and a lot of time has already passed since the introduction of sanctions. Everything that was put into operation at that time was mainly Western technologies and equipment, which, in fact, ensure to this day the reproduction of relatively competitive and in-demand products both on the domestic market and abroad, even under current restrictions.
Of course, one can refer to China in support of everything that the West previously supplied, but due to the commitment of the interests of the Celestial Empire to the American pointer and the risk of losing more for them if they step aside, this direction raises certain doubts. And the repayment of already accumulated debts to China has not yet had a downward trend. As they say: "pay off the old to get the new." And moreover, these are still external debts, not internal ones.
It seems that now there is only hope for the lifting of sanctions to restore what is gradually being lost or for reasonable and more active investment in the implementation of their own import substitution programs, the return on which will be in demand by the world market (the key here is reasonable).
Otherwise, the threatening depreciation of high-tech funds in the real sector will become an additional factor that can significantly worsen the current situation.
