【Abstract】 The optimal size of national debts is the size where optimal overall effects are achieved in national-debt-related economic activities. It is also the critical point for national debts, above or below which their economic and social effects would diminish. Since national debts were reissued in China in 1981, their annu al issue has been increased on such a large scale that they have become the focu s of attention. The present expansion in the size of national debts is intended to enhance aggregate supply and hence stimulate growth. There exists, however, a limit to the expansion of national debts.更多还原
