摘要
目前,工业结构变动率的计算方法主要有两种:绝对变动率和平均偏差变动率。我们认为前者直观简单,但不能体现行业自身变动的大小;后者能反映行业自身变动的大小,但忽略了大行业与小行业之间的差别。为此,本文提出了两种改进的方法:加权平均偏差变动率和修正加权平均偏差变动率,并以实例进行了分析比较。
At present,Industrial structure change can be arrived at mainly by two means： absolute change rate and average deviation change rate.The absolute change rate is straightforward and simple,but it can not reflect the extent of change the industry experiences;the average deviation change rate can reflect the extent of change the industry experiences,but fails to capture the differences between major and minor sectors.Therefore,the paper makes a few improvements to average deviation change rate,proposing the weighted average deviation change rate and calibrated average deviation change rate.Moreover,the paper provides an example for analysis and comparison.
