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.
