国防费作为军事财力主体,表现了军事经济实力大小,是军事实力形成的基础;而军事实力又要求一定的国防费规模与之相适应。本文运用计量经济学的有关方法,研究国防费概念数量规模增量与军事实力存量增量的关系,从国防需求角度确定了国防费规模与国防费适度增长区间。 As the main body of military financial resources, the defense expenditures show the strength of the military economic power and form the basis for the formation of military power. And the military strength requires that the amount of national defense expenditures be compatible with it. This essay uses the econometric methods to study the relationship between the increment of defense cost concept and the stock of military power, and determines the range of defense expenditure and the modest growth of defense expenditure from the perspective of national defense demand.
