补充资料:内部经济和内部不经济
内部经济和内部不经济
【内部经济和内部不经济】用以反映当一个生产单位扩大规模时由内部因素引起的收益变化状况的一对概念。 内部经济是指一个生产单位在扩大经营规模时由自身内部所引起的收益的增加。由于经营规模的扩大,企业内部可以实行更加精细的分工,降低管理人员的比重,购买大型的高效率的生产设备,充分利用副产品,减少购销费用,这些都会使企业的平均生产成本下降,使收益增加的幅度大于规模扩大的幅度,从而产生内部经济。 与内部经济相反的是内部不经济。内部不经济是指一个生产单位在扩大经营规模时,由自身内部所引起的收益的下降。由于规模过大使得管理不便、管理效率降低,内部通讯联系费用增加,需要增设购销机构,这些都有可能使生产过程呈现规模收益递减的特征,收益增加的幅度小于规模扩大的幅度,平均生产成本上升,造成内部不经济。
