消费与积累的比例,是国民经济中最综合、最重要的比例关系之一。合理积累率的研究,对于保证国民经济按比例地发展和获得较好的宏观经济效果,有十分重要的意义。本文仅就合理积累率研究中经常碰到的两个问题作一些探讨。(一) 合理积累率研究中的一个重要问题,是积累效果与积累率及国民收入增长率之间的关系。通常是用下面的公式来反映它们的关系的: 设α为报告期合计的积累率,δ为报告期国民收入平均增长率(这里是把国民收入生产额与使用额的差别忽略不计的),κ为表现积累效果的系数(即每增加单位国民收入所需的积累额),则有
The ratio of consumption to accumulation is one of the most comprehensive and important proportions in the national economy. The study on the reasonable accumulation rate is of great significance for ensuring the proportional development of the national economy and obtaining better macroeconomic results. This article only discusses the two problems that are often encountered in the study of reasonable accumulation rate. (I) An important issue in the research on the reasonable accumulation rate is the relationship between the accumulation effect and the accumulation rate and the growth rate of national income. Usually, the following formulas are used to reflect their relations: Let α be the cumulative rate of the reporting period, δ the average rate of growth of the national income during the reporting period (in this case, the difference between the GNP and the utilization rate is neglected) κ is the coefficient of cumulative effect (ie, the cumulative amount of national income per unit of increase), then
