一、“质循环”的必然趋势国防经济作为国民经济的子系统,其发展模式既遵循整个国民经济的运行规律,又有自己特殊的运行轨迹。国防经济“质循环”是国防经济自我运转的一种模式,它相对于“量循环”而言。“量循环”是指国防经济发展倾向于量的扩张,主要依靠大规模资源投入,实现国家安全目标。而国防占用资源越多、发展方式越粗放,质量和效率就越低,形成低水平循环。“质循环” I.

The “qualitative cycle” of national defense economy is a mode of national defense economy self-operation, which is relative to the “quantitative cycle”.
