在经济活动分析中,经常使用绝对数与相对数反映经济指标的增减量与发展速度。以往,在统计图表中往往只习惯使用普通图表来反映经济指标绝对数的增减情况,这样容易给人一种错觉。为了从直观感觉上,加深对问题的全面了解,本文认为,应该推广使用半对数图表来反映经济指标的相对数变化情况。此外,在统计分析中,还广泛使用指数法分析各种因素的影响程度。对此,作者提出自己的一种新的分析方法——几何图形法,并与指数法进行对比,指出:几何图形法不仅可以运用在单因素分析中,在某种情况下,它比指数法分析更为准确,而且还可以运用在多因素分析中,它比指数法分析更为简单,便于掌握。
In the analysis of economic activities, the absolute number and the relative number are often used to reflect the increase and decrease of economic indicators and the pace of development. In the past, it was easy to give people an illusion that they often used to only use ordinary charts to reflect changes in the absolute number of economic indicators in statistical charts. In order to deepen the comprehensive understanding of the problem from the intuitive feeling, this paper believes that we should promote the use of semi-logarithmic chart to reflect the relative changes in economic indicators. In addition, in the statistical analysis, exponential method is also widely used to analyze the impact of various factors. In this regard, the authors propose their own a new analysis method - geometry method, and compared with the index method, pointed out: Geometry method can not only be used in univariate analysis, in some cases, it is more than the index method More accurate analysis, but also can be used in multivariate analysis, it is more simple than the exponential analysis, easy to grasp.
