从理论上分析,军费支出作为政府开支的一个特例,其乘数等于投资乘数,它只能部分影响机会成本;国家税收规模越大,国防税收的量就可能越大,因而国防税收乘数也可以说就是税收乘数。从现实上看,尽管军费支出乘数、国防税收乘数及效应影响国家的财政政策,但同时它们也能自动调节军事经济中的资源配置,优化军事经济的结构。 Theoretically, military expenditures, as a special case of government expenditure, have a multiplier equal to the investment multiplier, which can only partially affect the opportunity cost. The larger the national tax revenue, the greater the amount of defense tax revenue, so the national defense tax multiplier It can be said that tax multiplier. In reality, though the military expenditure multiplier, national tax multiplier and effect affect the country’s fiscal policies, they also automatically adjust the allocation of resources in the military economy and optimize the structure of the military economy.
