It is pointed out that although the interest rate mechanisms in China has gone through several adjustments and reforms, the results are not yet fully up to expectations. The interest rate does not adjust the national economic structure, and direct the trend of funds, nor regulate the general social supply and demand and balance the price and currency in circulation, to achieve a rational distribution of social resources. The interest rate policy of Central Bank does not have much actual influence on the economic departments, and this influence was continuously weakened in recent years. Countermeasures are suggested for improving the macro control of interest rate.展开更多

The purpose is to pro- pose an optimal extraction series of these resources during the lifetime of the Mine＇s maintenance. Fol- lowing the proposed optimal control model, a sensitivity analysis has been performed that includes the interest rate impact on the optimal solution. This study shows that the increasing of the interest rate sti- mulates faster extraction of the resources. The discounting factor induces that the resource has to be extracted faster hut this effect is counterbalanced by the diminishing returns of the annual cash flow. At higher parameters of ＂alpha＂ close to one of the power function about 80% from the whole resource will be extracted during the first 4 years of object/mine maintenance. An existence of unique positive root with respect to return of investment has been proposed and proved by two ways： by the ＂method of chords＂ and by using specialized software.展开更多
