L’amortissement et l’autofinancement du processus d’investissement

A balanced economic development is essentially based on self-financing of investment cycle. The efficient use of energy resources and raw materials could rise by increasing the renewal of fixed capital, which is meaning also a shift to a higher technological level. From this correlation is resulting that the technical progress stands for an accelerator type multiplier of investments effects. Taking into account the economic growth factors and also the relationship between the efficiency, the degree of depreciation and the technical level a global model is built based on the propagation of investments self-financing. The model is showing the dependence of investments self-financing growth to the decrease in the functioning standard period of fixed capital, to their structural youthfulness and economic efficiency increase, seen through the ratio between net income and depreciation.
