The problems of a constant resumption of the creation process of the intellectual values and the intellectual services have not so far been considered in the economic literature for a number of reasons: first: an intellectual sphere has not been treated as an economic system; second: spare time of population has not been treated as a resource; third: an assimilated resource of spare time of population has not been included into a cost of an intellectual service; fourth: the peculiarities of economic relations in the intellectual sphere have not been elaborated; fifth: the peculiarities of economic interests in the intellectual sphere have not been disclosed, etc.
Any consideration of the problems on a reproduction of the intellectual sphere is to be started with establishing the resource streams coming in and out of it. This is an initial moment without which it is rather difficult to set up the critical points, a proportion, an equality and inequality in the schemes of a simple and expanded reproduction, to transfer to a higher level of understanding and solving the problems of this peculiar sphere of a human activity.
