「土地所有の偶有性」と有益費補償

抄録

　The purpose of this paper is to clarify the concept of terre-capital from the point of view of "accidental quality of land ownership." To this end, it is necessary to clarify the positioning in the principles of economics of the problem for unexhausted value of improvement, which may occur when a tenant capitalist in agriculture forms terre-capital. This problem is examined for unexhausted value of improvement from two sides: return of invested capital and return in terms of the increases in land rent. By supporting the idea that depreciation expenses based on the term of a land lease become a component of production costs in the case of terre-capital invested by a tenant capitalist, the following results are obtained.
　The problem for unexhausted value of improvement is not given an important positioning in the principles of economics, and is not concerned with the establishment of capital category. Consequently, the existence of recourse for unexhausted value of improvement is not necessary for the concept of modern land ownership. The problem of the unexhausted value of improvement is not a matter brought about by the inevitable law in a capitalistic society, but is instead a matter of consciousness and policy. Therefore, it was not "paradoxical" but "natural" that a legal remedy for the unexhausted value of improvement in England was established in the period of transition to monopoly capitalism.
