Their use is important for the efficiency valuation of the adopted decision by the central, regional and local institucions, that conduct the policy and the measures of the sustainable and integral rural development. The capital coefficients of the rural area we can calculate as the territorial and sector ones, the approximate and marginal ones, the usual and tehnological ones, and the coefficients to gross or not base. Their circulation in a rural complex understand the certain specifications, the analysis of the important subbefects in the investment process and the accumulation of the fixed funds respectively. This is particulary related to the changes of the country prices in the circulation, as a result of the long-standing investments into the sustainable development and the rural areas.
